hi,
assuming u use jstl, u need to create javascript variable during html generation out of the values got from struts form bean. it could look like this:
------ .jsp file ----
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<script type="text/javascript">
var X = [];
var Y = [];
<c:forEach items="${formBeanName.mdfProductNames}" var="grpProdName">
X.push( '${grpProdName.mdfProductName}' );
Y.push( '${grpProdName.subGroup}' );
</c:forEach>
// here u already have the two arrays filled up with data
</script>
------- end of .jsp file
"formBeanName" is a name of a formbean u use to store the list of your beans

Problem in assigning script array to Js variable

There is a huge list(20,000) of cities that has to be put into a script array for the further use in the jsp page. so this script array is created once for all when the login is made for the application and stored a session variable. The sample of the script array is like-----
<script>
strArrCityName[17463]= "Zoar";
strArrCityID[17463]= "10599";
strArrCityStateID[17463]= "3";
strArrCityName[17464]= "Zoarville";
strArrCityID[17464]= "10600";
strArrCityStateID[17464]= "3";
</script>
the entire stuff from <script>---</script>(uncluding the script tags is stored as a string in the session (strSessionCityArr))
Now the porblem is i need to store this array into a js variable on jsp page load.
I order to that i need to declare a js variable in jsp page
ex::
<html>
<body>
This is a sample jsp page created by <%= strUserName%>
<script>
var cityarry = "<%=session.getAttribute('strSessionCityArr')%>";
</script>
</body>
</html>
when i assign the array to the js variable , the <script> tag inside the string is conflicting with the <script> tag that of the jsp page.
This throws the js error and the futher loading of the page is stopped.
The reason i am storing it in the js variable is i will be painting the script array dyanamically on click of a button.
Also in need both the script tags in the array is in other jsp pages i will painting the array on page load by using the out.println(strCityArray)
I need a way in which this script array can be stored in js variable or any method by which i can directly get it from the session on button click
Thanx in advance
Manu

i had tired constructing the script array using the JS but JS logic is always slower ...my point was not to do it all with JS code. My point was that unless you know how to properly define it as JS-only code, then it makes it hard to figure out how to break that up to Java generated code. It's clear to me that you don't have a very good grasp of what you're trying to do.
The second point is, in some JSPs i need the <script> tags to be included in the array. No they don't. You can always put the <script> tags around what your Java variable includes if you are using that content in several places...
<script><%= session.getAttribute('strSessionCityArr') %></script>

How to assign java script variable to a hidden parameter in JSP?

Hi All,
I want to assign the variable in the Jscript to a hidden parameter in JSP page.
<select name="sortingOption" class="sortingOptions" onchange="changeSortOption(this)">
<c:forEach var="sortingOption" items="${sortingOptionList}">
<c:set var="sortingOptionValue" value="${sortingOption}" target="java.lang.String"/>
<c:choose>
<c:when test="${sortingOptionValue == sortingOptionValueFromRequest}">
<option value="${sortingOptionValue}" selected="selected">${sortingOptionValue}</option>
<input type="hidden" name="srchType" value="none"/>
</c:when>
<c:otherwise>
<option value="${sortingOptionValue}">${sortingOptionValue}</option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>
In changeSortOption script,they capture the value selected by the user and then they submit the form.I want to assign that value to a hidden parameter in JSP,can someone tell me how to do that?
I dont have the Jscript code with me right now to post here.

To the point: just by accessing/manipulating the HTML DOM using JS. Learn JS and HTML DOM. There are basic tutorials at w3schools.com. Besides, your code syntax is still invalid. The input hidden elemend doesn't belong in a select element. Learn HTML. There's a basic tutorial at w3schools.com as well.
For future HTML/JS problems please consult the appropriate forums. This has not much to do with JSP. There are ones at webdeveloper.com.

Using Java Script to set cookies of a JSP form

Hi,
i m new to JSP as well as Javascript. i have a JSP which has two fields which are generated dynamically based on a no. of rows in a datasource, for eg. product datasource and the fields are productId,A. I also have one href link which opens another jsp. I want to set the cookie for productid when the user clicks on the link. i have written a javascript for setting the cookie. but i get a error saying the variable prodid object is null or not an object.The code is something like this,
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
function setck(field) {
for (i = 0; i < field.length; i++) {
var pid = field.value;
if ( pid != null && pid.length > 0)
document.cookie = "CookieProductId" + i + "=" + pid;
</script>
</HEAD>
<BODY>
<center>
<form name=myform >
<jbo:ApplicationModule id="am" configname="FleetCardsBC.FleetCardsBCModule.FleetCardsBCModuleLocal" releasemode="Stateful" />
<jbo:DataSource id="dsProd" appid="am" viewobject="FmmProductsView"/>
<jbo:DataSource id="dsProdRes" appid="am" viewobject="FmmProductRestrictionsView"/>
<table>
<%int nRow = 0;%>
<%
nRow++;
String s1 = null;
Cookie[] cookies = request.getCookies();
if (cookies != null)
for (int i=0; i<cookies.length; i++)
s1 = "name: "+cookies[i].getName()+ " value: "+cookies[i].getValue();
out.println(s1);
%>
<jbo:RowsetIterate datasource="dsProd" >
<tr><td>Product Id </td>
<td><input type=text name="prodid" ></td>
<td>A value </td>
<td><input type=text name="A" ></td>
<td>
<a href="prodresdet.jsp" onfocus="this.value=setck(this.form.prodid)" >More Details</a>
</td>
</tr>
</jbo:RowsetIterate>
</table>
</form>
</center>
</BODY>
</HTML>
Interestingly the cookies get set if instead of a link i use a button. Can someone tell what m i doing wrong, using a link.
Thanks in advance
Unmesh

Doesn't work consistently.
Here is the file modified with your script:
https://www.box.com/s/09dzlu2kmiv7uziqef7j
The way it should work is that, when you enter in a code, such as 1, a type appears on the right hand side- either C or S. A C is an automatic Fail and should appear in the pass/fail box after entering in the 1 under the code column. After the Fail appears, the script should be called and the subform should appear.
Then, if you were to change the 1 under the code to a 6, the resulting type is an S which makes the pass/fail box turn to Pass. At this point, the subform should disappear.
Does that make sense?

Assigning a jstl variable to java Script variable

Hai All,
I created one jsp page with java script with JSTL.
I retrive arrayList from simple java bean in jsp page with help of JSTL .
Now i want assign the ArrayList value through JSTL to Java Script Array.
How to convert JSTL to Java Script.
Please give me details asp.
thanks ,
Bala

You can do this:
<% request.setAttribute("x", "hello"); %>
<c:out value="${x}"/>or if you want to go from JSTL to scriplet you can:
<c:set var="testvar" value="hello" scope="request"/>
<%= request.getAttribute("testvar") %>Both of these will output "hello"
<c:set> defaults to the page scope, so you could substitute pageContext for request and get the same results (remove scope="request" first though).

How to pass values to variables in WAD 7.0 using java script

Hi.,
My requirement is based on WAD 7.0.
The sales value has to displayed in WAD using graph with various chart types.
I have created variables for plant and material group in a query.
I have created drop down box for plant with all plants in it, check box for material group and a Submit button in WAD in FORM tag of HTML coding.
Once all the values are set in drop down box, checkbox and if the user clicks on submit button, the values has to captured by the variables for which I have created and the graph has to be aligned to the new values in variables.
Kindly help me how to use java script to get the values from FORM and pass it to variables.
Regards,
Selva

Hi Selva,
You do not need to use Javascript for this. Instead you can achieve this by using API Commands in WAD 7.0.
Please configure Action on the ButtonGroup webitem to use 'Commands'.
->Choose Command 'Set Variables Values / SET_VARIABLES_STATE' under Commands for Web Templates
->Set Display Variable Screen setting to OFF
->Choose Query Variable for Plant, Select Variable Type as 'Binding Type', Binding Type as 'Data Provider Selection', Data Provider as the one you have assigned to the Dropdown webitem, Characteristic as 0PLANT or as that assigned to the Dropdown webitem
->Repeat above steps for Query Variable Material Group
Now when you make a selection from the Dropdown webitems, the Chart output will change accordingly. Let me know if this helps.

Column link - call java script & assign current report column value to item

Hi,
How to call java script and assing current report column value to item?
I have a button column in the report to 'delete' the selected row.
I want to first show dialog box with message 'Are you sure?'. If yes, process to delete
will be executed, else no action.
In order to fire JS, I used Column Link ->Target=URL.
Problem: The alert is showing but I don't know how to pass selected row's primary
key value to process (to delete selected row).
I have a item which can be used to store selected primary key value but don't know how to assign the value
when button pressed.
Thanks in advance
Dip

Ok. The issue has been resolved by following way.
PAGE PROCESS: delete_request
begin
delete xyz
where id = :P8_id;
commit;
end;BUTTON URL:
javascript: DelRec(null,'CREATE', 'f?p=&APP_ID.:8:&SESSION.:delete_request:NO::P8_id:#id#');Java Script:
<script language="JavaScript1.1" type="text/javascript">
function DelRec(msg, req, url){
var confDel = msg;
if(confDel ==null){
confDel= confirm("Are you sure?");
}else{
confDel= confirm(msg);}
if (confDel== true){
redirect(url); }
</script>
