js实现的map
这是一个通过js实现的map，不是我自己编写的，是群里的一位朋友分享的，我觉得有需要的时候可以考虑使用。
function Map() {var struct = function(key, value) {this.key = key;this.value = value;}var put = function(key, value){for (var i = 0; i < this.arr.length; i++) {if ( this.arr[i].key === key ) {this.arr[i].value = value;return;}}this.arr[this.arr.length] = new struct(key, value);}var get = function(key) {for (var i = 0; i < this.arr.length; i++) {if ( this.arr[i].key === key ) {return this.arr[i].value}}return null;}var remove = function(key) {var v;for (var i = 0; i < this.arr.length; i++) {v = this.arr.pop();if ( v.key === key ) {v=null;continue;}this.arr.unshift(v);}}var size = function() {return this.arr.length;}var isEmpty = function() {return this.arr.length <= 0;}this.arr = new Array();this.get = get;this.put = put;this.remove = remove;this.size = size;this.isEmpty = isEmpty;} 1 楼 mercyblitz 2010-06-28 JS自带Directory，其实就是Map实现。
