จากบทเรียน Ajax Auto Fill Textbox อยากทำให้ Row มันเพิ่มแถวเองไปเรื่อยๆ เมื่อเรากรอกรหัส ทำยังไงครับ

	function fncCreateElement(){
	
	   var mySpan = document.getElementById('mySpan');
		
	   var myLine = document.getElementById('hdnLine');
	   myLine.value++;

	   // Create input text
	   var myElement1 = document.createElement('input');
	   myElement1.setAttribute('type',"text");
	   myElement1.setAttribute('name',"txtGalleryName"+myLine.value);
	   myElement1.setAttribute('id',"txt"+myLine.value);
	   mySpan.appendChild(myElement1);	
	
	   
	   // Create input file
	   var myElement2 = document.createElement('input');
	   myElement2.setAttribute('type',"file");
	   myElement2.setAttribute('name',"fileUpload"+myLine.value);
	   myElement2.setAttribute('id',"fil"+myLine.value);
	   mySpan.appendChild(myElement2);	

	   // Create select
	   var myElement3 = document.createElement('select');
	   myElement3.setAttribute('name',"selSelect"+myLine.value);
	   myElement3.setAttribute('id',"sel"+myLine.value);
	   mySpan.appendChild(myElement3);	

	   // Create Option //
	   fncCreateSelectOption(myElement3)
		
       // Create <br>
	   var myElement4 = document.createElement('br');
	   myElement4.setAttribute('name',"br"+myLine.value);
	   myElement4.setAttribute('id',"br"+myLine.value);
	   mySpan.appendChild(myElement4);

	}
