jQuery Plugin: Adding Callback functionality

Question

I\'m trying to give my plugin callback functionality, and I\'d like for it to operate in a somewhat traditional way:

myPlugin({options}, function() {
    /*          


        

Answer 1

Just execute the callback in the plugin:

$.fn.myPlugin = function(options, callback) {
    if (typeof callback == 'function') { // make sure the callback is a function
        callback.call(this); // brings the scope to the callback
    }
};

You can also have the callback in the options object:

$.fn.myPlugin = function() {

    // extend the options from pre-defined values:
    var options = $.extend({
        callback: function() {}
    }, arguments[0] || {});

    // call the callback and apply the scope:
    options.callback.call(this);

};

Use it like this:

$('.elem').myPlugin({
    callback: function() {
        // some action
    }
});
