Passing an array into a JSP from a struts action.
I am passing an array of string values from my database into a jsp via a form bean. The array of string values were retrieved and and loaded into the form bean in a Struts action.. However, when I do this:
<input id='ValueList' type='hidden' value='<%=valueList%>' />
The array is not getting assigned correctly to the hidden input variable correctly.
These javascript lines are not working well:
var answer = [];
answer = document.getElementById('V
alert('MY VALUE LIST:::::' + answer[0]);
Is there a way to do this that actually works?

dxdinh has a good point. Try using
<input id='ValueList' type='hidden' value='${valueList[0]}' />
<input id='ValueList' type='hidden' value='${valueList[0]}' />
As per i know thats not possible bcz your array list have more than beans values so you cant take that values in java script .
do one thing just print this value
<input id="ValueList" type="text" value="<%=valueList%>" />
you will get result like this

so you can put that values like this
<%
List a=(ArrayList) request.getAttribute("valu
Formbean fb;
for (int i=0; i<a.size;i++)
{
fb=(Formbean) a.get(i);
%>
<input type="hidden" id="hidd<%=i%>" name="hidd" value="<%=fb.getName()%>">
<%}%>
in java script
var answer = document.formname.hidd.val
thats all

in java script
var answer = document.formname.hidd.val
thats all

dravidnsr has made a correct point. He left alot of useful examples. I would like to give him 200 points. I did give the other responder the initial points. I really do appreciate their effort. This is better than a text book since I got great help on a problem I encountered in practice.
I don't know Struts but that can't work. The expression <%= %> is for accessing scripting variables on the page. I think you should try
<input id='ValueList' type='hidden' value='${valueList}' />
or
<input id='ValueList' type='hidden' value='<%=session.getAttri
or maybe
<input id='ValueList' type='hidden' value='<%=request.getAttri
