Question

I am trying to invoke the primefaces commanlink via javascript and want to know whether it executed successfully or not and if it is successful i need to get the values which sent by callbackfunction. I am capturing the return value of the commandlinke which is a bunch of javascript. How to get the args(topicComment) value in my senario. I think i can do a workaround by setting few more hidden fields, but i want to see how to get it directly.

Javascript

$('.postButton').livequery("click", function (){
        var comment_content = $(this).parent().siblings().children('textarea').val();
        $('#topic_comment').val(comment_content);
        var object=$('#postCmdLink').click();
        var output;
        for (property in object) {
              output += property + ': ' + object[property]+'; ';
            }
            console.log(output);
}

Server side

public void addComment(){
        .................................
        context = RequestContext.getCurrentInstance();
        context.addCallbackParam("topicComment", topicBean.getTopicCommentVO().getTopicCommentGuid());

}

Instead of clicking CommandLink by jQuery:

var object=$('#postCmdLink').click();

Uses Primefaces AjaxAPI to call ajax and register a callback to get the result:

PrimeFaces.ajax.AjaxRequest({
         formId:'userForm'
         ,source:'userForm'
            ,process:'userForm'
         ,update:'msgs'
         ,params:{
            'param_name1':'value1',
            'param_name2':'value2'
         }
          ,oncomplete:function(xhr, status, args) {alert('Done');}  
        });

Primefaces User documentation 3.1.1 section 7.2 Ajax API page 454.
