Jquery: Checking to see if div contains text, then action

Yes, I now made think for me. And it works fine!!!

if($("div:contains('CONGRATULATIONS')").length)
                        {
                            $('#SignupForm').hide(500);
                        }

Ayman is right but, you can use it like that as well :

if( $("#field > div.field-item").text().indexOf('someText') >= 0) {
        $("#somediv").addClass("thisClass");
    }

if( $("#field > div.field-item").text().indexOf('someText') >= 0)

Some browsers will include whitespace, others won't. >= is appropriate here. Otherwise equality is double equals ==

Your code contains two problems:

• The equality operator in JavaScript is ==, not =.
• jQuery.text() joins all text nodes of matched elements into a single string. If you have two successive elements, of which the first contains 'some' and the second contains 'Text', then your code will incorrectly think that there exists an element that contains 'someText'.

I suggest the following instead:

if ($('#field > div.field-item:contains("someText")').length > 0) {
    $("#somediv").addClass("thisClass");
}
