我想爲現有的jQuery插件創建一個腳本#封裝。該jQuery插件實現了「原型繼承與DOM到對象的橋模式」,可以在this link腳本#封裝原型繼承jQuery插件
// myObject - an object representing a concept that you want
// to model (e.g. a car)
var myObject = {
init: function(options, elem) {
// Mix in the passed-in options with the default options
this.options = $.extend({}, this.options, options);
// Save the element reference, both as a jQuery
// reference and a normal reference
this.elem = elem;
this.$elem = $(elem);
// Build the DOM's initial structure
this._build();
// return this so that we can chain and use the bridge with less code.
return this;
},
options: {
name: "No name"
},
_build: function(){
//this.$elem.html('<h1>'+this.options.name+'</h1>');
},
myMethod: function(msg){
// You have direct access to the associated and cached
// jQuery element
// this.$elem.append('<p>'+msg+'</p>');
}
};
// Object.create support test, and fallback for browsers without it
if (typeof Object.create !== 'function') {
Object.create = function (o) {
function F() {}
F.prototype = o;
return new F();
};
}
// Create a plugin based on a defined object
$.plugin = function(name, object) {
$.fn[name] = function(options) {
return this.each(function() {
if (! $.data(this, name)) {
$.data(this, name, Object.create(object).init(
options, this));
}
});
};
};
// Usage:
// With myObject, we could now essentially do this:
// $.plugin('myobj', myObject);
// and at this point we could do the following
// $('#elem').myobj({name: "John"});
// var inst = $('#elem').data('myobj');
// inst.myMethod('I am a method');
再次什麼是問題? – 2013-03-26 12:36:08
