How to post zk url through javascript

Question

Assume you have a content.zul and you want to get it via ajax in javascript, this can be done by using zk built in jquery in zul page or using jquery in pure html.

zul sample:

<zk>
    <script><![CDATA[
        function loadContent () {
            jq.ajax({
                url: "content.zul",
                type: "post",
                // callback handler that will be called on success
                success: function(response, textStatus, jqXHR){
                    jq('$content').html(response);
                }
            });
        }
    ]]></script>
    <div id="content"
        onCreate='Clients.evalJavaScript("loadContent();");' />
</zk>

html sample:

<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
        <script type="text/javascript">
            window.onload = function () {
                $.ajax({
                    url: "content.zul",
                    type: "post",
                    // callback handler that will be called on success
                    success: function(response, textStatus, jqXHR){
                        $('#content').html(response);
                    }
                });
            }
        </script>
    </head>
    <body>
        <div id="content"></div>
    </body>
</html>
