其实有点标题党了，呵呵，主要是项目的特殊性，出于性能考虑项目经理规定不能用任何服务端控件(包括Repeater控件)，同时尽量减少服务端处理，并尽可能压缩最终生成的html源代码，所以只用JS实现。
代码:

/*
hashTable的javascript实现

function hashTable() {
this.__hash = {};
//添加key-value键值对
this.add = function(key, value) {
if (typeof (key) != "undefined") {
//if it not contains in hashtable
if (!this.contains(key)) {
this.__hash[key] = typeof (value) == "undefined" ? null : value;
return true;
}
else {
return false;
}

//删除key-value键值对

this.count = function() {
var i = 0;
