I have an int variable in that gets passed into a jsp file from a java class. I now want to pass this int value from the jsp to a javascript file I have. I am stuck with a coming up with a solution. I have tried the following but still does not work:
javascript:
jQuery(document).ready(function() {
jQuery('div.awsmp-hero-featureSwap').each(function() {
jQuery(this).find('div.hero-featureSwap').each(function() {
var width = 0;
var height = 0;
var count = 1;
var perpage = "${products_per_page}"; // ***** this is the value I want from the jsp*****
var totalcarousel = jQuery('.hero').length;
jQuery(this).find('div').each(function() {
width += jQuery(this).width();
count = count + 1;
if (jQuery(this).height() > height) {
height = jQuery(this).height();
}
});
jQuery(this).width(((width / count) * perpage + 1) + (perpage * 12) + 60 + 'px');
jQuery(this).height(height + 'px');
});
});
JSP:
<c:set var="products_per_page" value="3" />
<c:if test="${not null model.listSize}">
<c:set var="products_per_page" value="${model.listSize}" />
</c:if>
I just want to pass the the "products_per_page" value to the javascript. should be very simple...

Try doing it this way->
servlet_file.java
HttpSession session = request.getSession();
session.setAttribute("idList", idList);
.jsp file
<%
HttpSession session1 = request.getSession();
ArrayList<Integer> idList = (ArrayList<Integer>) session1.getAttribute("idList");
%>
.js file
alert("${idList}");

I passed the request argument to my onclick handler in js the following way:
<s:submit name="kurierButton" onclick="openKurierWindow('%{#attr.OUTBOUND_KURIER_URL}');" value="%{#attr.OUTBOUND_KURIER}"/>

You can use this, is not very recommendable.... but works.. Hard-coding the value into the html file like this:
<body>
.....
var x = <%= some_value %>;
.....
</body>

you can put your <c:set>
block into an HTML element as its value then get the value easily using Javascript or jQuery
example :
<input id="ppp" type="text" value="<c:set var='products_per_page' value='3' />"/>
js:
var products_per_page = document.getElementById("ppp").value;
