How to check null objects in jQuery

Question

I\'m using jQuery and I want to check the existence of an element in my page. I have written following code, but it\'s not working:

if($(\"#btext\" + i) != n         


        

Answer 1

use $("#selector").get(0) to check with null like that. get returns the dom element, until then you re dealing with an array, where you need to check the length property. I personally don't like length check for null handling, it confuses me for some reason :)
