ขอความช่วยเหลือหน่อยครับ คือตามรูปเลยครับ ผมได้ส่งค่าผ่าน url และมารับค่า และทำการส่งค่าผ่าน Ajax เพื่อน select ข้อมูลออกมา ข้อมูลนั้นเป็นภาษาไทยครับขณะที่ส่งมาเป็นภาษาไทย

$('#detail').live("click",function(e){
				 e.preventDefault();
				var val=$(this).val();
				var url="popupDetail.php?detailCode="+val;
				var name="";
				var windowWidth="850";
				var windowHeight="850";  
				var myleft=(screen.width)?(screen.width-windowWidth)/2:100;	
				var mytop=(screen.height)?(screen.height-windowHeight)/2:100;	
				var properties = "width="+windowWidth+",height="+windowHeight;
				properties +=",scrollbars=no, top="+mytop+",left="+myleft;   
				window.open(url,name,properties);
				alert(url);
			});

function PageQuery(q) {
			if(q.length > 1) 
	  this.q = q.substring(1, q.length);
			else
	  this.q = null;
			this.keyValuePairs = new Array();
			if(q) {
	  for(var i=0; i < this.q.split("&").length; i++) {
			 this.keyValuePairs[i] = this.q.split("&")[i];
	  }
			}
	
			this.getKeyValuePairs = function() {
	  return this.keyValuePairs; 
			}
			
			this.getValue = function(s) {
	  for(var j=0; j < this.keyValuePairs.length; j++) {
			 if(this.keyValuePairs[j].split("=")[0] == s)
		return this.keyValuePairs[j].split("=")[1];
	  }
	  return false;
			}
	
			this.getParameters = function() {
	  var a = new Array(this.getLength());
	  for(var j=0; j < this.keyValuePairs.length; j++) {
			 a[j] = this.keyValuePairs[j].split("=")[0];
	  }
	  return a;
			}
	
			this.getLength = function() {
	  return this.keyValuePairs.length;

	}
	function queryString(key){
			var page = new PageQuery(window.location.search);
