Question

I have added a transparent div on a window(with treeview) as follows in a function :

function add()
{
$dialog.html('<div id="div1"  style="background: url(img/trans.png); opacity:0.1; filter:alpha(opacity=10); "></div>');
}

How do I remove this div so that I can see the contents of the window again in another function.

Answer 1

$('#div1', $dialog).remove();

It’ll remove the div which id’s #div1 from the $dialog.

If you use $dialog.html() you’ll overwrite the html content, so try to use append if you want to get it back.

Look this demo.
