jquery插件公共函数

这个最适合我。

(function($){
    $.fn.editor = function(options){
        var defaults = {},
        settings = $.extend({},defaults, options);
        this.each(function(){
            function save(){
                alert('voila'); 
            }
            $.fn.editor.externalSave= function() {
                save();
            }
        });

    }
})(jQuery);

呼叫

$(function(){
    $('div').editor();
    $.fn.editor.externalSave();
});

call method

var save = function () {

   var self = this; // this is a element of each

};

(function($){
    $.fn.editor = function(options){
        var defaults = {},
        settings = $.extend({},defaults, options);
        this.each(function(){
           save.call(this) // you can include parameters 
        });
    }
})(jQuery);
