<div id="a"></div>
if($("#a").is(':empty') )
alert("empty");
In IE8, it shows alert but Mozila 3.6 and Opera 11 do not show the alert. Why?
Answer:
if(!$.trim( $("#a").html() ) )
alert("empty");
this code run in ie and mozila
Your code is valid and should work in those browsers. I tested it in FireFox and Chrome and it works.
Verify that you do not have any other elements in your page that also have an id of
a. Most browsers compliant with web standards correctly refuse to acknowledge any duplicated elements and often it causes JavaScripts to fail due to errors.
