I want to call one javascript function from my button click on server side and pass the arraylist, string array or list as a parameter to the function. I would then need to iterate through all the elements of these collection and perform some action on the data. Can you tell me the javascript code to access these elements ?

Consider the following structure that I have in the Javascript:

JavaScript

function ABC(_Arraylist/List/String Array){

//I would like to perform some action on the collections data here. 

}

Thanks.

Sample code to generate and access a collection is:

XML

<script type="text/javascript">
    function generate(){
        var arr = new Array();
        <c:forEach items="${articles}" var="a" varStatus="status">
            $('#listitems').append(
                "<li>"+${a.title}+"</li>"
            );
            arr[${status.index}] ="${a.slideShow.images}";
        </c:forEach>
    }
    function generate(){
        var arr = new Array();
        <c:forEach items="${articles}" var="a" varStatus="status">
            alert(arr[${status.index}]);            
        </c:forEach>
</script>

Solution 2

Used the string instead of passing arraylist to the javascript and then created the arrays from the string.This solved my problem
