Question

Starting Situation

These two commands should be equivalent.

jQuery('a').filter(':contains(about)');

and

jQuery.find('a').filter(':contains(about)');

Problem

In fact, the first command performs well, whereas the second throws the following exception:

TypeError: :contains(about) is not a function

Why ist that? Shouldn’t jQuery('a') and jQuery.find('a') return the same object? If not, what’s the difference?

Explanation

I am dynamically building a JQuery command chain (part of a JQuery Java Wrapper which is used in my project Abmash). Therefore, i prefer a chain of methods like jQuery.find('a').filter(':contains(about)').

Answer 1

jQuery.find('a') returns a array (Array.filter() takes a function as argument.)

jQuery('a') returns a jQuery-array-like-Object
