Check if a DIV id exists with JQuery

Question

Using Javascript I\'m trying to test whether or not a DIV with the id \"test_div\" exists in the document.

I\'m using

if (getElementById(\"test_div\"))
<         


        

Answer 1

Your case is incorrect in your sample code. You should be invoking getElementById, with a lowercase d. Javascript is case sensitive.

If you're using jquery, make sure to prefix id with a #, like so $("#test_div"), so jquery knows you want to query for an element id.

Answer 2

You would have to do document.getElementById(id). But seeing how you are using jquery - you could also do $(id).length > 0 to check if the element exists
