Jquery Plugin Public Method/function

I am trying to achieve something like the following but dont know whats wrong: $.a = function() { // some logic here function abc(id) { alert('test'+id); } } $.a.abc('1');

Solution 1:

Since $.a must be a function in itself, you'll have to add the abc function as a property to the $.a function:

$.a = function () {
    // some logic here...
};

$.a.abc = function (id) {
    alert('test' + id);
};

If abc must be defined from within the $.a function, you can do the following. Do note that $.a.abc will not be available until $.a has been called when using this method! Nothing inside a function is evaluated until a function is called.

$.a = function () {

    // Do some logic here...// Add abc as a property to the currently calling function ($.a)arguments.callee.abc = function (id) {
        alert('test' + id);
    };
};

$.a();
$.a.abc('1');

Solution 2:

$.a = (function(){
    var a = function() {
        //...
    };
    a.abc = function() {
        //...
    }
    return a;
})();
