Implementing Hidden Fields?

Hi
Im trying to create a registration form.
I have created the form which includes user name and password
text fields, by using the record insertion form wizard.
Dreamweaver has inserted a hidden field, but how do I change
the properties of this to insert the data into a database (mysql).
I am also using Java, JSP.
Thanks for your help, Lou.

Hidden fields in an HTML form are passed to the server via HTTP (GET or POST) in exactly the same way as visible fields.

Pivot Table - Calculate Variance - Hidden Fields?

I need some help adding a target value field inside a pivot table in excel.
Here is what my current pivot table looks like.
Regions                 1 year - Actual              1 year - Target??
Difference
                  (April 2013 to MArch 2014)
(Target - Actual)?
Region1                $6,355,696.75
Region2                $6,775,309.87
Region3                $2,230,424.76
Regions expand into managers which in turn expand to consultants.
What I want to do is add a column for target values of the 3 different regions and then create another calculated field that will show the difference between the target and actual values.
Can this be done without writing any stored procedures in SQL? I want to do this in excel itself.
The target values are not calculated so can we store them in hidden fields or something in the pivot or excel?

1. Click anywhere in Pivot and go to Options tab > Formulas > Calculated Field.
2. Create a calculated field called Target (whatever name your choose). If your target is say 7000000, put this value in Formula field. You may put it with or without =
3. Now after this, you can once again create a new Calculated Field. Let's say this is Variance. If you variance is Target - Actual, put this as =Target-Actual in Calculated Field.
4. Your pivot will have whatever you wanted.

How to pass hidden field values on a click of a table row

hi all,
href = "bookAndNonBook.do"
I am very new to struts. I have created a table using displaytable tag which displays results in a tabular format. In addtion, i have a hidden field (prodType), the table rows are getting highlighted when i get my mouse on a particular row.
Following is the code from the results.jsp file
<body
onload="addRowHandlers('row', 'rowMouseOver')"
bgcolor="#FFFFFF" text="#000000" leftmargin="100" topmargin="50"
marginwidth="" marginheight="" rightmargin="30">
<html:form action="/bookAndNonBook" method="post">
<display:table name="sessionScope.productSearchList" id="row"
sort="list" export="true" defaultsort="1" defaultorder="ascending"
pagesize="15" decorator="org.displaytag.decorator.TotalTableDecorator"
class="dataTable">
<display:column property="prodType" title="ProdType" class="prodType"
headerClass="prodType" media="html" />
<display:column title="Title" property="titleName" sortable="true"
class="title" headerClass="title" />
</display:table>
</html:form>
</BODY>
I am calling a funtion addRowHandlers which passes the table id (which is row) and the rowMouseover for highlighting the rows on mouse over.
the code for function addRowHandlers is
function addRowHandlers(tableId, rowClassName) {
var previousClass = null;
var table = document.getElementById(tableId);
var rows = table.getElementsByTagName("tr");
for (i = 1; i < rows.length; i++) {
rows.onmouseover = function () {
previousClass = this.className;
this.className = this.className + " " + rowClassName ;
this.style.cursor="hand";
rows.onmouseout = function () {
this.className = previousClass;
this.style.cursor='';
rows.onclick = function (){
var cell = this.getElementsByTagName("td")[0];
var ProdType = cell.innerHTML;
alert("value of prodType = " + ProdType);
when i run the above code and click on a particular row it returns me the value in the hidden field i.e. prodType for that particular row
Now where i am having problem is i want that on the basis of prodType my jsp file should call different actions for different prodType as returned....somwhat a function like this
function submitProduct(prodType) {
if(prodType == "BK")
resultsForm.action = "/bookProduct.do";
else if(prodType == "NB")
resultsForm.action = "/nonbookProduct.do";
but i am unable to figure out that how do i this..
Any help will be really appreciated
Thanks
Sam

can you please suggest some good struts forums where i can post my question
thanks in advance

Hidden field in form returns null value

Hi all - I searched for this but found nothing that fit my problem although various other problems came up.
I have a Login jsp, with a simple form for username and password:
<form name="login" method="post" action="servlet/ControlServlet"
onSubmit="return validateForm()"><table width="180" border="0"
cellspacing="0" cellpadding="0">
            <tr>
              <td width="96" class="logintext">Username</td>
              <td width="84"> </td>
            </tr>
            <tr>
              <td><input name="username" type="text" size="15"
maxlength="15"></td>
              <td><input type="submit" name="Submit" value="Login"></td>
            </tr>
            <tr>
              <td class="logintext">Password</td>
              <td> </td>
            </tr>
            <tr>
              <td class="logintext"><input name="password" type="password"
size="15" maxlength="15"></td>
              <td><input name="actionCode" type="hidden" value="0"></td>
            </tr>
            <tr>
              <td> </td>
              <td><div align="center"><a href
="Register.jsp"><i>Register</i></a></div></td>
            </tr>
          </table>
          </form>Nothing complex in that form. my hidden field is actionCode and it should pass a 0 to my ControlServlet servlet.
Here is a snippet from my servlet:
import java.io.* ;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ControlServlet extends HttpServlet {
public void doPost(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html");
            //get the printwriter to output for debugging
            PrintWriter out = response.getWriter();
            //read in form variables
        //String formUsername = request.getParameter("username");
        //String formPassword = request.getParameter("password");
        String action = request.getParameter("actionCode");
        //convert String to int for action
        //int actionInt = Integer.parseInt(action);
        //add action variable to request
        request.setAttribute("aktion", action);
            //debug point 1
            //use requestDispatcher to forward session info to JSP
           RequestDispatcher dispatcher =
           request.getRequestDispatcher("/mvcoutput.jsp");
           dispatcher.forward(request, response);I have commented out a bit for debugging purposes, but basically, the form variables are read in, the username and password don't give me any problems, but the actionCode does. Upon forwarding to a basic jsp for testing my output displays value "null" when using the command:
request.getAttribute("aktion")Any reason why the hidden field is playing silly buggers ??
cheers

Anyone ???
If I have a field in an html form which is hidden, do I retrieve it in the SAME WAY that I retrieve the non hidden form fields i.e. using the request.getParameter() method ??
Cheers.

Add hidden fields in ALV

Hi all,
   I wanna add a new field in ALV field catalog, so that when user choose function Change Layout to decide which fields are showed, they can choose the new field.
In orginal source, the ALV uses field catalog from structure<b> LIPOV.</b> And the field I wanna add is just a normal text field (char15, for example) and its data will be extracted from a select statement.
So, Here is the logic of report:
data: ls_fieldcat type slis_fieldcat_alv.
call function 'REUSE_ALV_FIELDCATALOG_MERGE'
        exporting
          i_internal_tabname     = 'itab_data1'
          i_structure_name       = 'LIPOV'
          i_client_never_display = 'X'
        changing
          ct_fieldcat            = ct_fieldcat[]
        exceptions
          inconsistent_interface = 1
          program_error          = 2
          others                 = 3.
After this call, i add new field
    ls_fieldcat-col_pos = 110. " above function will retrieve a field catalog with 109 records
    ls_fieldcat-fieldname = 'new_text_field'.
    ls_fieldcat-tabname = 'itab_data1'.
    ls_fieldcat-seltext_l = 'NEW'.
    ls_fieldcat-no_out = 'X'.
    APPEND ls_fieldcat to ct_fieldcat .
    clear ls_fieldcat.
Here, I copy all data from<b> itab_data</b> to <b>itab_data1</b>
Display:
   call function 'REUSE_ALV_LIST_DISPLAY'
      exporting
        i_buffer_active          = 'X'
        i_callback_pf_status_set = gf_status
        i_callback_user_command = gf_user_command
        i_structure_name         = 'LIPOV'
        is_layout                = gs_layout
        it_fieldcat              = ct_fieldcat
        it_events                = lt_events
        it_sort                  = gt_sort
        is_variant               = gs_variant
      tables
        t_outtab                 = <b>itab_data1</b>
      exceptions
        program_error            = 1
        others                   = 2.
Please note that there are something special here:
Originally, ALV displayed with internal table itab_data.
The new filed is a part of internal table itab_data1.
<b>And the problem is:</b>
When I choose Change Layour (Ctrl F8) to select the new field to display, It does not appear in HIDDEN FIELD.
Any suggestion, plz.
Thank you very much.

Clemens Li,
Thanks for your advice.
I have a new problem. Now, the new field appears in Selection. However, displaying the new field is impossible. My problem is:
- In default, 8 fields will display. Then, I use CHANGE LAYOUT to choose the new field which will be at 9th position. -> <b>I got a dump</b>... It informs that a Field Symbol is not assigned.
- Now, with the 8 fields above, I replace 8th position by the new field => It does not give me a dump but New field shows value of 8th field. I mean, if at first, 8th field is Quantity with value 10. Then I replace 8th field by my new field. When displaying again, it also gets 10 as its value.
- It is so strange. Because in function 'REUSE_ALV_LIST_DISPLAY', I used itab_data1, which consists of all field of itab_data and an addition field (NEW). I dont know why it does not show value of the new field while all old fields have right values. (before using that function, I copied all contents of itab_data to itab_data1)
So, everybody can help me this? Thanks

How can I display a letter grade in my gridview after calculating percentage into a hidden field in Visual Studio?

For school I am working on an app using C# in visual studio that allows a student to enter their name, the number of points they earned and the points possible. When they click a submit button, the grade percentage is calculated in a hidden field and then
the percentage and letter grade should spit out into the gridview. THe issue I am having is trying to figure out how to translate within the if statements regarding the percentage amount equalling whatever letter grade, and then spit that letter grade out
into the gridview. Here is the code I have so far:
        protected void btnSubmit_Click(object sender, EventArgs e)
            SqlStudent.Insert();
            hdnGradePercent.Value = (((int.Parse("txtPointsEarned.Text")) / (int.Parse("txt.PointsPoss.Text")) * 100)).ToString();
            if ((int.Parse(hdnGradePercent.Value) >= 0) & ((int.Parse(hdnGradePercent.Value) <= 59)))
(this is where I am having trouble. I can't figure out how to get the letter grade and percent to spit out into the   gridview.)
            else if ((int.Parse(hdnGradePercent.Value) >= 60) & ((int.Parse(hdnGradePercent.Value) <= 69)))
            else if ((int.Parse(hdnGradePercent.Value) >= 70) & ((int.Parse(hdnGradePercent.Value) <= 79)))
            else if ((int.Parse(hdnGradePercent.Value) >= 80) & ((int.Parse(hdnGradePercent.Value) <= 89)))
            else if ((int.Parse(hdnGradePercent.Value) >= 90) & ((int.Parse(hdnGradePercent.Value) <= 100)))
Any help would be greatly appreciated! I've been stuck on this for hours and I"m losing my mind!!

Hidden fields in a form Dreamweaver 8

I have a problem I can't resolve. I have with a bunch of
hidden fields in a form. The problem I have is that some of the
anchor points are not showing in design view for all the fields,
just a couple show up. I have View Invisible elements in Visual
aids turned on.
Fields 1,2,3,9,10,11,15 don't show
Fields 4,5,6,7,8,12,13,14 show
Here's the code, can someone tell me what I did wrong?
Any help will be appreciated

Hi Max,
This is possible in portal forms.
The code to get the value of a field is some thing like this.
You need to generate this javascript function using pl/sql in the Additional pl/sql Section - ... before displaying the page or ... after displaying the page.
htp.p('
<script>
function myFunc(ele)
var l_form = ele.form;
var win;
var val;
var l_url = "<url>?";
for (var i = 0; i < l_form.length ; i++){ // This is the way you traverse along all the form elements.
if (l_form.elements.name == "<field to be refered>"){ //something like this for the field you wish to refer ==> QUESTION_RESULT.MASTER_BLOCK.QID.01
val = l_form.elements[i].value;
l_url = l_url+val;
win=window.open(l_url);
</script>
Then call any fiels you wish to for the purpose of set or get of values.It can be even a hidden field.
Hope this helps,contact for further clarifications.

Adding a check box to my page clears the value in a hidden field on page 0

Hello, I hope that someone can assist me. I have a page that has multiple submit buttons on it. When I click a submit button the page refreshes to render the new content. I have a hidden field, and its region is set to one on page 0. Without any check boxes on my page, I can set a value in the hidden field, and it remains there even if I click on any submit buttons. If I put a check box on the page and then press a submit button, the value is cleared in the hidden element which is not desired. I did notice that in this case with the check box, if I refresh the browser the hidden field value is not cleared. Perhaps the page is being rendered differently after the submit because of the checkbox. Does anyone have any ideas of what is happening?

That doesn't sound right. Adding a checkbox shouldn't have that effect. Please try to reproduce this on htmldb.oracle.com so we can take a look or post a screenshot of your relevant page components.

Setting the value of a hidden field in a Visual Web jsf page

Hey All,
I am new to jsf and need some help with the following. I have written a method in the java portion of the jsf page that will get the selection(s) from a listbox and return them as a string. I need to assign the value of that string to a hidden field in the jsp portion of the page, so that I can pass the string as a parameter to a servlet. I have tried the following code in the "button_action", in the java portion of the jsf page, to assign the value of the string, returned from method, to the hidden field:
hiddenField.setValue(string);
This is not working. Any and all help on this matter is greatly appreciated.
Thanks in advance.

Here is the tag for the hidden field when the "hidden field" component is added from the pallette, I addded the "value" and "id". The name of the class is ReportStandard, which extends the AbstractPageBean.
<webuijsf:hiddenField binding="#{ReportStandard.utilSelHF}" id="utilSelHF" value="#{ReportStandard.utilParams}"/>This is how I am calling the hidden field in the servlet:
utils = request.getParameter("form1:utilSelHF_field");Here is the code for the button_action:
public String runReport_button_action() {
this.utilParams = get_utilSelection();
return "sRptrslts";
}

Access HTML hidden field value in JSP

<form name="login">
<input type="hidden" name="language" value="en">

You read it as any other field :
String lng=request.getParameter("language");
The string lng will contain the value "en"

Can't set a hidden field value from onClick event with a runtime expression

Hi,
I need to set a hidden field in an onClick event of button but it's not working.
<html:submit styleClass="btnLink" onclick="document.empForm.hidden.value='<%= empID%>'">
<%= empID%>
</html:submit>
Althought the second expression is evaluated and written successfully "the button value"
I heard that this is because you can't mix the value of an attribute of a custom tag with both string literal and run time expressions.
Is there any work around to solve that?
I can't use EL as I'm using old JSP version

I guess, it should work; instead of html:submit, try with button.

Hidden field value init. by a var in Netscape && MSIE ...

          Hi there,
          I have a hidden field specified this way :
          <input type = "hidden" name = <%=myName%> value = "<%=myValue%>">
          Suppose that myValue is 'Ionut RUSUBOCA'
          If I run this with Netscape 4.75 it works just fine.
          If I run this with Microsoft IE 5.50.4522.1800 I get an error that points to the
          way the hidden field value is specified.
          If I change ...... value = "<%=myValue%>" ..... to .... value = <%=myValue%>
          ... ( that is, if I remove the double quotes ) then MSIE is Ok but ... instead
          of 'Ionut RUSUBOCA' I only get 'Ionut'.
          Could you, please, help me make MSIE see the correct value that is 'Ionut RUSUBOCA'
          ? ( like Netscape )
          Which browser are not W3C compliant in this matter ?
          Thank you,
          rivisa


          Thanks for the reply.
          Well, I quoted everything and still does not work with MSIE.
          Indeed, when I quote value="<%=myValue%>", I get in MSIE value = "Ionut RUSUBOCA"
          but it does not make any difference : it breaks.
          If I take out the quotes ( value = <%=myValue%> ) then the source is viewed as
          value = Ionut RUSUBOCA and when the form
          gets submitted I only get 'Ionut' as value.
          This is weird, so to speak.
          Can you reproduce this thing in your system ?
          Thanks,

Acrobat 9.3.2 printing hidden fields automatically

We have a few clients internally running Acrobat Standard 9.0.0 and their documents are printing fine. One user upgraded to 9.3.2, and now when they try and print some of our documents, a hidden field area is automatically printing. I can't seem to find a way to turn it off. It doesn't appear in the document, or in print preview. Choosing to Examing the document and remove it removes the text, but not the spacing that the hidden area added. is there a setting to never print this? It's not something we want to have to adjust each time we open a document.

Glad it helped; (for any nit-pickers out there I should have typed 8.2.2, sorry).
There are others with similar issues:-

Why my JSP page can't get the value of a hidden field

Hi, I got an interesting question here.
I use req.getParameter() method to get a hidden field in Servlet, it works just fine.
However, when I use the JSP to catch the value of that hidden field, JSP just can't, but if I change the type from hidden to text, it works fine again.
the code is as follows:
there are two jsp pages:game.jsp and GameMonitor.jsp.
In game page:
============================================================
<FORM action=GameMonitor.jsp method=post
webbot-action="--WEBBOT-SELF--">Display the names of all the players currently
connected to the server       <INPUT tabIndex=1 type=submit value=Lookup name=B1>
<INPUT TYPE=hidden,value=1 name=p1>
<P></P></FORM>
===========================================================
I want GameMonitor.jsp to catch the value of hidden field "p1" by calling request.getParameter()
the code catching it in the GameMonitor.jsp is:
============================================================
String option = request.getParameter("p1");
          out.println("option=["+option+"]");
          try{
               if(option.equals("1")){
===========================================================
supurisingly, the result is option=[], which means it didn't catch the value of the p1 submitted by POST method.
Does anybody here can tell what's wrong in the code?

Thank you so much, I also found this error, which makes JSP not able to catch the hidden field, however, if I change it to text type, even the comma exists, it still works. pretty interesting!
>
<INPUT TYPE=hidden,value=1 name=p1>Modify the above lline and write like this....
<INPUT TYPE="hidden" name="p1" value="1">
And ensure that you're submitting the form data.
Though nothing much has been changed, just try whether
these help!!!

Hidden Field Value

I want to import a value from a visible field to a hidden
field. The data will be sent to a mySQL DB via php. I've tried
changing the php script to obtain the results I want
unsuccessfully. A hidden field should also do the trick but I'm not
sure how to accomplish the task. A google search turned up some
javascript which I've been working with today, but still haven't
gotten to work correctly.
Basically, the form has a text field called duration. I want
the user inputed value of the duration field to be copied to a
hidden field called xc. Thanks for any input or ideas?

BTW, using the following onSubmit and script works correctly
as the database receives the information, but a pop-up is triggered
when the Submit button is pressed. Any ideas why this is?
If I can rid the pop-up, the js will work great.
function CopyValue(obj1, obj2)
var visibleField = obj1;
obj2.value = visibleField.value;
alert(obj2.value);
onSubmit=CopyValue(duration, xc)

Implementing Hidden Fields?
