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?<

In jQuery 1.8 you will need to use

jQuery.expr[":"].icontains = jQuery.expr.createPseudo(function (arg) {                                                                                                                                                                
    return function (elem) {                                                            
        return jQuery(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;        
    };                                                                                  
});
