如何使用jquery扩展插件中的公共方法?

$.fn.myPluginName = function(PublicOptions) {

    // Remember the root assigned object.
    var Root = this;

    // Set private defaults.
    var Defaults = {
        param1:       'param1',
        param2:       'param2',
        onSuccess:    function(){}
    };

    // Do a deep copy of the options - http://goo.gl/gOSSrg
    var Options = $.extend(true, {}, Defaults, PublicOptions);

    // Private debug function.
    function log(msg) {
        console.debug(msg);
    }

    // Define the public api and its public methods.
    var PublicApi = {

        method1 : function (PublicOptions) {

            return "extended method 1";
        },
        method2 : function (PublicOptions) {

            return "extended method 2";
        }
    };

    // Return the PublicApi object.
    return PublicApi;
};

我希望将它们放在var PublicApi = {}

中的扩展方法
var extensionMethods = {

   method3: function(){
       return "extended method 3";
   },

   method4: function(){
       return "extended method 4";
   }
};

目前,console.log($(this).myPluginName());

Object {method1=function(), method2=function()}

但如果我可以将方法扩展到,那将是理想的,

Object {method1=function(), method2=function(), method3=function(), method3=function()}

有可能吗?

您可以通过稍微修改代码(例如

)将对象传递给插件
$.fn.myPluginName = function(extMethods){
    //(...) Some code here
    PluginApi = { ... }   // your default methods go here
    if(typeof extMethods == "object"){
       for(var key in extMethods)
           PluginApi[key] = extMethods[key];
    }
}

if块的作用是,它检查提供的参数是否为对象,然后使用PluginApi循环将属性名称的方法添加到for...in

您可以拨打$(this).myPluginName(extensionMethods);
