Help needed - Moving values to another drop down

**harikrishna_di** · 05-19-2009, 06:05 AM

Hi,

I want to move values from one drop down to another drop down. When I move the selected value is being removed from first drop down. Instead, I want to keep the value in first drop down & move it to second drop down.

This is the code i am using.

Code:

function moveoutid()
	{
		var sda = document.getElementById('fromList');;
		var len = sda.length;
		var sda1 = document.getElementById('toList');
		for(var j=0; j<len; j++)
		{
			if(sda[j].selected)
			{
				var tmp = sda.options[j].text;
				var tmp1 = sda.options[j].value;
				sda.remove(j);
				j--;
				var y=document.createElement('option');
				y.text=tmp;
				try
				{sda1.add(y,null);
				}
				catch(ex)
				{
				sda1.add(y);
				}
			}
		}
	}

	function moveinid()
	{
		var sda = document.getElementById('fromList');
		var sda1 = document.getElementById('toList');
		var len = sda1.length;
		for(var j=0; j<len; j++)
		{
			if(sda1[j].selected)
			{
				var tmp = sda1.options[j].text;
				var tmp1 = sda1.options[j].value;
				sda1.remove(j);
				j--;
				var y=document.createElement('option');
				y.text=tmp;
				try
				{
				sda.add(y,null);}
				catch(ex){
				sda.add(y);	
				}
	
			}
		}	
	}
