Im using struts2 tags for my application. I need to change the value randomly from script to s:set tag and populate into the javascript array. If i add dynamically means i get the output as 2012 - diff + 1 but my expected output as 2011 . How can i achieve this, my code is

var threeDatas = [];
var prevyear = [];
var diff;
var flagthree = false;

<% int j = 0;%>

<s:iterator value="testlist">
    prevyear.push(<s:property value="year"/>);
    if (<%= j - 1%> !== -1) {
        if (prevyear[<%= j - 1%>] !== prevyear[<%= j%>] - 1) {
            diff = prevyear[<%= j%>] - prevyear[<%= j - 1%>];
        }
        if (diff > 1) {                                                   
            for (inc = 1; inc < diff; inc++) {
                <s:set var="incyear"> <s:property value="year"/> - diff+1</s:set>
                 threeDatas.push(['<s:property value="#incyear"/>', null, null]);
            }
            flagthree = true;
            diff = 0;
        }

<% j++;%>

</s:iterator>

i need my final array value should be link

['x', 'Cats','Dogs'],
     ['2008',   10, null],
     ['2009',   20, null],
     ['2010',   null, null],
     ['2011',   null, 23],
     ['2012',   null, 34]

You can use the eval() method in JavaScript. So, if you can generate something like

var incyear = eval('<s:property value="year"/> - diff + 1');
