I am trying to set a background color for an ID + Variable but I can't figure it out. There must be something really small that I am not aware of.

Here is what I have:

var abc = $dialog.data( url );

alert(abc)

This Alerts: item1

var cde = '#' + abc

alert(cde)

This Alerts: #item1

So far so good. Now, I'm trying to change the background for that ID.
So:

This works:

$(body).css('background-color', 'black');

This doesn't:

cde.css('background-color', 'black');

$(cde).css('background-color', 'black');

$(# + abc).css('background-color', 'black');

All are in the same function.

What I'm I doing wrong?

Thanks a lot

The only reason I see that your code is not working is because the value that you pass to jQuery (namely cde or # + abc) is not of type String.

You can do some test for that :

var test = #item1;

alert(test === cde);

alert(typeof(cde));

If the type is not string, then you could simply do :

$(cde.toString()).css('background-color', 'black');
