$FNLIST contains a string that looks like this...

'6263,2894,4231,2937,4846,4790,2909,2852,4875,4881,4801,2931,4831,4832,4833,4778,2878,4809,4883,4061,4869,2941,7134,'

Message: Object doesn't support this property or method

Line: 228

Char: 3

Code: 0

URI: http://path/tap.php

 

The JS Code :

 

function UnfoldTree(divArray)
{
	alert(divArray);
	var myArray = divArray.Split(',');
	for(i in myArray)
		{
			document.getElementById( i ).style.display = 'block';
		}
}

I suspect the problem is that  the "Object doesn't support this property or method"

 

I suspect you are wanting to reference the objects with IDs the same as the values in your array?

 

When you do a For...In within JavaScript, the FOR value is not the value in the array - it is the index of the value. I think what you want to do is this:

 

function UnfoldTree(divArray)
{
alert(divArray);
var myArray = divArray.Split(',');
for(index in myArray)
{
	document.getElementById( myArray[index] ).style.display = 'block';
}
}

Still get that same error, and your assumption is correct. Somewhere on the page i have these ID's generated that store the data, and they are not displayed by default, and clicking that 1 button will show them all. If you know any other way to do this other then what i'm trying please feel free to show me, im open to all ideas.

Got it!

 

function UnfoldTree(divArray)
{	
	alert(divArray);
	var fnarray = divArray.split(",");
	for(i in fnarray)
		{
			alert(fnarray[i]); // Show divs isntead.

		}
}

 

it's because the .Split was with initial capitol letter instead of .split.  DOH !!! i hate case sensitive programming.
