js常用方法或对象封装------待续中。。。。
/** * @author wsf */;(function (){/** * 模拟继承 * @param {Object} dest * @param {Object} src */function extend(dest,src){for(var i in src) dest[i] = src[i];return dest;}extend(Object.prototype,{extend:extend});//为object添加extend方法var arrayAddM = {/** * 为array对象添加indexOf方法 * @param {Object} v */indexOf : function (v){for(var i = 0; i < this.length;i++){if(this[i]===v) return i;}},/** * 为array添加get方法 * @param {Object} v */get : function (v){alert(this.indexOf(v));return this[this.indexOf(v)]},/** *为array增加put方法：将指定元素插入到数组指定下标出 * @param {Object} v * @param {Object} idx */put : function (v,idx){return this.slice(idx,0,v)},/** * 数组删除元素方法 * @param {Object} v */remove : function (v){return this.slice(this.indexOf(v),1)},/** * 是否包含指定元素 * @param {Object} v */contain : function (v){return this.indexOf(v)>=0}}Object.extend(Array.prototype,arrayAddM);//为数组对象添加方法var stringAddM = {/** * int value */intVal : function (){return parseInt(this);},/** * float value */floatVal : function(){return parseFloat(this);},/** * 判断是否为数字型 */isNum : function (){return isNaN(this*1);}}Object.extend(String.prototype,stringAddM);//为string 对象添加加方法var mapAddM = {store : new Array,/** * entry函数 * @param {Object} key * @param {Object} val */entry : function (key,val){this.key = key;this.value = val;},//put方法put : function (key,val){this.store[this.store.length] = new this.entry(key,val);},//get方法get : function (key){for(var i = 0 ; i < this.store.length;i++){if(this.store[i].key === key)return this.store[i].value;}},//remove方法remove : function (key){for(var i = 0 ; i < this.store.length;i++){this.store[i].key === key && this.store.splice(i,1);}},//keysetkeySet : function (){var keyset = new Array;for(var i = 0 ;i< this.store.length;i++) keyset.push(this.store[i].key);return keyset;},//valsetvalSet : function (){var valSet = new Array;for(var i = 0 ; i < this.store.length;i++) valSet.push(this.store[i].value);return valSet;},//clearclear : function (){this.store.length = 0;},//size size : function (){return this.store.length;}}Map = function (){};Map.prototype = {};Map.constructor = new Map();Object.extend(Map.prototype,mapAddM);//为Map增加方法})();
