Is there an “exists” function for jQuery?

Question

How can I check the existence of an element in jQuery?

The current code that I have is this:

if ($(selector).length > 0) {
    // Do something
}
<         


        

Answer 1

You could use this:

jQuery.fn.extend({
    exists: function() { return this.length }
});

if($(selector).exists()){/*do something*/}
