Question

Its probably simple but I am not able to do it. I want to find and select all elements of a class which are not contained under a given id.
For Example: Below here, how to find elements of class “me” outside id “con”

<div id="con">
    <div class="me">hi1</div>
    <div class="me">hi2</div>
</div>
    <div class="me">hi3</div>
    <div class="me">hi4</div>

Answer 1

$(".me").not("#con .me");

Using not() you can specify a selector that the elements should not match.

This could also be written as:

$(".me:not(#con .me)");
