Question

I have a jstl file which consists of a javascript snippet.

<res:useJS target="exec-js">
new current.myfunction({
my_arg:{
<c:forEach items="${arguments.value}" var="dataresults" varStatus="loopcount">
    <c:out value="\"${dataresults}\" ${!loopcount.last ? ', ' : ']'}"/>
</c:forEach>
 });
<res:useJS>

But when I run it I get an error saying “invalid property id” and when I look at the content – something like this has been passed. "data_res1&#034,"data_res1&#34,. I need to have double quotes in the results as that’s how I am parsing it in the javascript function. Any ideas on how this could be done?

<c:out> converts special characters to HTML entities to prevent injections.

You can use StringEscapeUtils.escapeJavaScript from Apache commons to escape your string and then output the plain value with

"${escapedText}" ${!loopcount.last ? ', ' : ']'}
