I offer that we expanded the UxGet function a little with parameter callback function.

It can be, by Uxget call from javascript. For example for processing of the conditional display-hiding and layout arrangement when it is necessary to cause function right after loading of AJAX of result.

example of use (in html page):

<script  type="text/javascript">
	var hiding = false;
	function update_expand_hiding_status() {
		// some updates ... of css and div attributes
	}

	function maintable_update(){
		if (enable_update){
			//UxGet($MainReportTableUpdate);
			UxGet($MainTableUpdate,update_expand_hiding_status);
		}
	};

</script>

modification of skylark.js::

function UxGet(request,callback) // <===========Add parameter as callback function
{
	var xmlhttp = AjaxRequest();
	xmlhttp.onreadystatechange = function() {
		if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
			ProcessAjaxResult(xmlhttp.responseText.split('\1'));
			if (callback) {    // <=========== if parameter callback is passed,
				callback();// <=========== call parameter function.
 			}                  // <===========
		}
	}
	xmlhttp.open("GET", request, true);
	xmlhttp.send();
}
