how to create jquery plugin

 In this article, we are going to see, how to create a jquery plugin.

sometimes you want to make a piece of functionality available throughout your code. for example, you want a single method you can call on a jquery selection that performs a series of operations on the selection. in this case, you may want to write a plugin.

here I'm writing a basic jquery plugin

(function($) {

    $.TDATE = (function() {

        return new Date();

    })();

}(jQuery));

or:

(function($) {

    $.TSUM = function(a,b) {

        return a + b;

    };

}(jQuery));

or:

(function($) {

    $.fn.TCOLOR = function() {

        this.css('color','red');

  return this;

    };

}(jQuery));

$('#error').TCOLOR();
