Append to a list? 1

[static786]

I'm trying to create a lis for which every time the code is executed, it appends the new values to the end of the list. I've tried the following, and it does'nt work. Can someone provide suggestions. (for some reason it always equals null?)

if(listXY == null)
{
alert("list eq null");
var listXY=clickedX+","+clickedY;
}
else
{
alert("list eq summit");
listXY=","+listXY+","+clickedX+","+clickedY;
}

You need to declare your variable listXY as a global variable. Don't declare it local to the function...

var listXY = null; // outside the function

function somefunc() {
...
if(listXY == null)
{
  alert("list eq null");
  [s]var[/s] listXY=clickedX+","+clickedY;
}
else
{
  alert("list eq summit");
  listXY=","+listXY+","+clickedX+","+clickedY;
}
...
}

Cheers,
Jeff
