What jQuery plugins do you use to make your life easier?

Question

JavaScript

To work with jQuery, by default, I take jquery-cookies into every project, and then I realized that there are more opportunities to make my life easier. But fantasy doesn't work.

Recommend a plug-in or better several at once - a set to simplify life. Something that can be safely included in every project. Well, plugins like jquery-cookie.

Answer 1

Pretty good almost everywhere

jQuery.fn.exists = function () {
        return this.length !== 0
    }

Also often

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

Of the detepicker plugins, one of the autocompletes is often needed. but not always the same.
