How to put a jsp variable into a javascript function?

Please read the following coding. I want to pass the variable ans from jsp to the function check_answer() of javascript. ans is a string got from database. But I cannot put the variable ans into the Javascript function. Can anyone help?
<script language="Javascript">
function check_answer() {
if (testing.result.value==ans ){
window.alert("You have got 10 marks.");
</script>
<body>
<form name="testing"...>
<%
ResultSet rs = stmt.executeQuery("select * from level where...");
while(rs.next())
out.println("<tr>");
out.println("<td>" + rs.getString("question") + "</td>");
ans = rs.getString("answer");
out.println("</tr>");
out.println("<input type='text' name='result'>);
out.println("<input type='button' value='Enter' onclick='check_answer()'>");
%>

The following should be able to pass ans.
<script language="Javascript">
function check_answer(ans) {
if (testing.result.value==ans ){
window.alert("You have got 10 marks.");
</script>
<body>
<form name="testing"...>
<%
ResultSet rs = stmt.executeQuery("select * from level where...");
while(rs.next())
out.println("<tr>");
out.println("<td>" + rs.getString("question") + "</td>");
ans = rs.getString("answer");
out.println("</tr>");
out.println("<input type='text' name='result'>);
out.println("<input type='button' value='Enter' onclick='check_answer('<%= ans%>')'>");

How do I enter a variable into an equation?

How do I enter a variable into an equation?

Jacob,
Spreadsheets don't use equations, so the usual nomenclature can be confusing.
When you enter something into a spreadsheet cell, it is either a Literal Value (Constant), or an Expression, preceded by an equal sign, that tells the spreadsheet to display something. Every Cell Reference in the Expression is a Variable. The equal sign in this case does not signify an equality, it just signals the spreadsheet that you want it to do something, defined by the expression that follows.
Here's an equation: A1 = B1 + C1 + 10, where B1 and C1 are variables and 10 is a constant.
To figure out what the value of A1 is, you write an expression in cell A1. That Expression would be: =B1 + C1 + 10. The operation that is performed by the spreadsheet is that it looks at B1 and C1, adds whatever it sees there and then adds the constant 10, and displays the result in A1.
It can get very complex. Expressions can contain Functions that catch the Time or generate a random number, or round a value, etc. Just remember that anything you see in a cell can be changed, so that content, that cell address, is a variable

I loaded my ipad photos from camera and all the pictures sorted by date. Next, I did a sync with my computer and the photos were all reorganized into IMPRT folders an out of date sequence. Any idea how to put the photos back into date files?

I loaded my ipad photos from camera and all the pictures sorted by date. I later sync my ipad with my computer and the photos were all reorganized into IMPRT folders an out of date sequence. Any idea how to put the photos back into date files other than reloading all of them from camera?

What version of iPhoto?
Select one and rotate it. Then rotate it back. Does that make it appear?
A much better work flow is the keep the photos after importing. Check the success the import, wait for at least one successful backup cycle then use you camera's format command to reformat the card

Parsing JSP variable into JavaScript

Hi,
I am trying to parse a JSP variable into a pice of JavaScript code:
<%
some jsp code .....
String table_name=cols[0].toString();
%>
<script language="javascript">
var jsTemp = <%=table_name%>
alert ('jsTemp')
</script>
<%some more JSP....
This does not create an alert, any ideas why? Am I missing a quote/semi-colon somewhere?

Sure this is being executed,
when trying to run, this does not work:
String table="TEST";%>
<script language="javascript">var jsTemp = <%=table%> alert ('jsTemp');</script>
<%more JSP...
when trying to similarly run, I get the popup 'HELLO':
String table="TEST"; //not used anymore%>
<script language="javascript">var jsTemp = "HELLO"; alert ('jsTemp');</script>
<%more JSP...
Is there supposed to be a semi-colon after <%=table%> ? Or is there another issue with this bit of code?

How to import existing jsp project into jdeveloper

can someone help me how to import existing jsp project into jdeveloper?
can give me step by step to import..cause i am new for jdeveloper..
thank you very much

Well there are two options - if you have a WAR file with the code in it, then you can use the file->import WAR.
Or you can use the new->Project from source code.
Note that you'll probably need to do some library settings and some directory setting after that.
Have a look at this demo for basic steps:

How do I look up how to put Cafe townsend tutorial into dreamweaver

How do I ask how to put Cafe Townsend Tutorial into dreamweaver. I have a mac. The tutorial notes say follow this line
(Mac OS X) Macintosh HD/Users/your_user_name/Documents/local_site. I don't understand what each section means. If someone called explain it that would be great as I ended up with an empty folder in dreamweaver with the name 'Cafe Townsend' on it. Thank you

Right. It's an empty local site folder until you put something into it.
Go to step 2. Download and unzip the Check_Magazine.Zip files
http://download.macromedia.com/pub/developer/check_magazine.zip
Go to step 3. Copy the check_magazine folder into your local_sites folder (Cafe Townsend).

Accessing JSP variables in Included Javascript

Hey All,
I want to hide my javascript to be viewed on the client browser.
I know we can do that with the javascript include ,But i am using JSP variables in
Included javascript.I can't access those variables any more.
Does anybody know any workarround.
Thanx
Vijay

Hi Vijay,
I am also facing the same problem of hiding javascript in the client browser. My javascript variables are getting initialised on the fly using JSP. Since JSP is compiled on the server side, one can't compile .js file on the client side.
What u can do is to divide your page into frames with
<frameset rows="100%,0%">. Now put your form hidden fields or the .js file in frame 2 which is not visible to the user and then assign your jsp variables in the frame2 html/jsp page. Now access your variables from frame2 in frame1 using
var i = parent.frames[1].document.forms[0].elements[0].value
Assuming that there is 1 form and 1 hidden field in frame2 html/jsp page.
I hope u get the logic rite....
I had done it for application but problem is that our users are real MORONS and they keep doing ctrl+F5 which takes them to the Indexpage.
If you get some other solution then please mail it to my email address
[email protected]

How to pass a JSP var to a Script function called in a netui:checkbox

How to pass a JSP variable to a Java Script function called in a netui:checkbox onSelect?
I have a requirement where based on the checkBox selected or deselected in a repeater tag I would have to select or deselect other checkboxes in a netui:form. I am trying to pass the index or unique name of the checkbox to the JavaScript function. When I try this code I am getting a Syntax Error!! and getting a " item undefined" in the javascript. This works when I use just the html form tag but when I use the <netui:form> tag I am facing this issue. Any help would be highly appreciated.
function selectACheckBoxOnClick(name) {
alert ("called selectACheckBoxOnClick ");
alert ("called name "+name);
<netui-data:repeater dataSource="{pageFlow.unregisteredContractAssetsDTOArr}">
<netui-data:repeaterItem>
<% String checkboxName = "selectACheckBox_"+i;
String serialNum = "serialNum_"+i;
String hidenboxName = "hiddenACheckBox_"+i;
String loopNo = new Integer(i).toString();
System.out.println("Loop String :"+ loopNo);
System.out.println("CheckBox Name:"+ checkboxName);
System.out.println("serialNum :"+serialNum); %>
<tr bgcolor="#ffffff">
<td align="center">
<netui:checkBox dataSource="{container.item.selectedAssetFlag}" onSelect="selectACheckBoxOnClick(<%=checkboxName%>);" tagId="<%=checkboxName%>"/>
</td>
          <td class="small"><netui:label value="{container.item.model}"/></td>
          <td class="small">
<netui:hidden dataSource="{container.item.splitAssetNo}" tagId="<%=serialNum%>"/>
<netui:label value="{container.item.serial}"></netui:label></td>
          <td class="small"><netui:label value="{container.item.equpimentId}"/></td>
          <td class="small">
<netui-data:getData resultId="siteId" value="{container.item.siteNo}" />
<%String siteId = (String) pageContext.getAttribute("siteId");%>
<netui:anchor action="getSiteLevelAssets" formSubmit="true">
<netui:parameter value="{container.item.siteNo}" name="siteNo" />
<netui:label value="{container.item.siteNo}" />
</netui:anchor>
</td>     </tr>
<%i++;%>
</netui-data:repeaterItem>
</netui-data:repeater>
This code works within a form:
               <td align=center>
                    <input type=image name="unassign" onclick="javascript:unassignReplacement(<%=replacementSupply.getPMSupplyId()%>)" src="<%=request.getContextPath()%>/images/bt_sm_x.gif" border=0 alt="Unassign">
                    </td>
Thanks,
Salome

hi
i did not go thru your code completly
but u can use the following for your problem
the checkbox in the repeater must have unique TagID
counter = 0; (initialize)
<netui-data:repeaterItem>
<netui:checkBox dataSource="" tagId='<%="count"+String.valueOf(counter)%>' onClick="some function()" />
<%counter++;%>
</netui-data:repeaterItem>
here if u have 3 checkbox
They will have Tagid's as count1 , count2 and count3
now in the javascript somefunction()
use the following line
for(j=0;j<<%=counter%>;j++)
document.forms(0)[getNetuiTagName"count"+j)].checked=false;
}

How to store serval char variables into a string variable?

I have serval char variables, but i don't know how to put them together (without using arrays). I am thinking to store these char variables into a string variable but i don't know how to do it. For example,
char letter1 = 'a', letter2 = 'b', letter3 = 'c';
String letters;
then how can i do to make letters = "abc" from using letter1,2,3?
I am just a beginner of Java, if anyone can help me, i will appreciate that very much!!!

String letters=""+leter1+letter2+letter3;is fine and dandy. What it actually compiles to is
String letters = new StringBuffer().append(letter1).append(letter2).append(letter3).toString();Which ofcourse is much more code to write, but still good to know.
So do see the API for java.lang.StringBuffer.

i already have the JSP file with me. can somebody please tell me how to put that onto the APEX?
Thanks,

One way using JSP portal is, creating Portal project with JSP Dynpage applications
You can use NWDS tool to create JSP Dynpage based Portal components.
Procedure to create and deploy Portal components,
1. Open Enterprise Portal Perspective in NWDS
2. Create -> new Portal Project -> Give the valid name
3. Right click on the project -> Choose Portal Object -> JSP Dynpage -> Give all the information including JSP name. -> Finish
4. Right Click on the project structure -> Properties -> Java Build Path -> All the following jars
htmlb, com.sap.portal.html_api.jar, servlet
5. Navigate to your JSP page located under the folder PORTAL-INF, Write logic
6. Right click on the portal projet-> Refresh -> Re-Build
7. Right Click on the portal project -> Export -> Give the Valid Portal serverdetails, Admin user name and password
8. You can create iView (iView from PAR) in content admin for the developed portal component
