篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了我的miniQuery相关的知识,希望对你有一定的参考价值。
经过两周的JS OOP学习,为了记录这难忘的时刻,写了一个mini的Query
下面便是代码咯!
(function(){ //构建变量保存window. var _$ = window.$; var _Query = window.Query; var Query = window.Query = window.$ = function(selector){ return new Query.fn.init(selector); } //处理原型 Query.fn = Query.prototype = { //给这个包添加一个初始化方法 init : function(selector){ //获取所有选择器指定的元素对象 var eles = document.querySelectorAll(selector); //将所有元素添加到this中,形成对象型数组 Array.prototype.push.apply(this,eles); //将this返回 return this; }, Query : "1.0.0", length : 0, size : function (){ return this.length; } }; // Query.fn.init.prototype = Query.fn; //实现继承,通过调用这个方法,可以不断的为Query添加功能 //添加静态 //添加实例 Query.exdent = Query.fn.exdent = function(){ //参数是一个对象 var o = (arguments[0] instanceof Object ? arguments[0] : {}); //将对象的属性和属性值一个个动态添加到this中 for(p in o){ this[p] = o[p]; } } //添加静态方法 Query.exdent({ //解决冲突 noConflict: function( deep ) { window.$ = _$; if ( deep ) window.jQuery = _Query; return jQuery; }, //循环 each : function(data, callback){ for(d in data){ try{ callback(parseInt(d),data[d]);

通过Query.exdent和Query.fn.endent方法,可以为Query添加无数静态方法,原型方法!有兴趣的朋友可以拿过去试一试!虽然有些东西考虑的不完善。。。
