Just print it in JavaScript syntax instead of HTML syntax.

    var data = {
        <c:forEach items="${cTagBean.tagList}" var="ctag" varStatus="loop">
            '${ctag.name}': ${ctag.age}${!loop.last ? ',' : ''}

So that it end up as valid JavaScript object (assuming that name returns String and age returns Number):

    var data = {
        'foo': 10,
        'bar': 5,
        'waa': 20
