Is there a case insensitive jQuery :contains selector?

Question

Is there a case insensitive version of the :contains jQuery selector or should I do the work manually by looping over all elements and comparing their .text() to my string?<

Answer 1

May be late.... but,

I'd prefer to go this way..

$.extend($.expr[":"], {
"MyCaseInsensitiveContains": function(elem, i, match, array) {
return (elem.textContent || elem.innerText || "").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;
}
});

This way, you DO NOT tamper with jQuery's NATIVE '.contains'... You may need the default one later...if tampered with, you might find yourself back to stackOverFlow...
