รบกวนถามเกี่ยวกับการส่งตัวแปรใน ajax คับ งงมาหลายวันแระ

	function ds_ajax(p,txtSearch) {
		
		init_ajax();
		var url = 'list_data.php';
	var pmeters = '&page='+p+ '&sid=' + Math.random();
	var pmeters = "&page=" + p + "&txtSearch=" + txtSearch + '&sid=' + Math.random();

HttPRequest.open('POST',url,true);

HttPRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
HttPRequest.setRequestHeader("Content-length", pmeters.length);
HttPRequest.setRequestHeader("Connection", "close");
HttPRequest.send(pmeters);
