What is the best practice of including jQuery ext functions?

Question

I currently have a file that I named JQuery.ext.js, which I include in all of my pages. Inside this file, I have many functions that perform the following actions:

(function($) {


    /**
     * Checks to see if a container is empty. Returns true if it is empty
     * @return bool
     */
    $.fn.isEmptyContainer = function() {
        //If there are no children inside the element then it is empty
        return ($(this).children().length <= 0) ? $(this) : false;
    };

    /**
     * Strip html tags from elements
     * @return jQuery
     */
    $.fn.stripHTML = function() {
        var regexp = /<("[^"]*"|'[^']*'|[^'">])*>/gi;

        //Loop through all elements that were passed in
        this.each(function() {
            $(this).html($(this).html().replace(regexp, ""));
        });
        return $(this);
    };

    /**
     * This function will check the length of a textarea and not allow the user to go beyond this length.
     * You should use the onkeypress event to trigger this function
     *
     * @param event event This value should always be event when passing it into this function
     * @param maxlength int The maximum amount of character that the user is allowed to type in a textarea
     */
    $.fn.enforceMaxLength = function(event, maxlength) {
        //Only allow the client code to use the onkeypress event
        if(event.type == 'keypress') {
            //If the client code does not pass in a maxlength then set a default value of 255
            var charMax = (!maxlength || typeof(maxlength) != "number") ? 255 : maxlength;

            //If the user is using the backspace character then allow it always
            if(event.which == 8) { return true; }
            //Else enforce the length
            else { return ($(this).val().length <= charMax); }
        }

        //Will only get here if the event type is not keypress
        return false;
    };
})(jQuery);

Is there any other way to do this? or is it like most people do?

Thanks for any help, Metropolis

EDITED

Added different plugins for the code and removed verification plugins

Answer 1

It all depends on the volume of these functions. If you have a list of very common functions that you constantly use in your applications, I would put them in a separate file and include them if necessary.

Edit

, / jQuery, , :

(function ($) {
   // my list of functions, plug-ins, or classes; as needed by the application
}(jQuery);

. : , /, 3 : jquery.myvalidation.js, jquery.myformatting.js .. , , , , "" jQuery ( ) ( ).
