js-map

copy直接用即可

function Map()
{
this.container = new Object();
}


Map.prototype.put = function(key, value)
{
this.container[key] = value;
}


Map.prototype.get = function(key)
{
return this.container[key];
}


Map.prototype.keySet = function() 
{
var keyset = new Array();
var count = 0;
for (var key in this.container) 
{
// 跳过object的extend函数
if (key == 'extend') 
{
continue;
}
keyset[count] = key;
count++;
}
return keyset;
}


Map.prototype.size = function() 
{
var count = 0;
for (var key in this.container) 
{
// 跳过object的extend函数
if (key == 'extend')
{
continue;
}
count++;
}
return count;
}


Map.prototype.remove = function(key) 
{
delete this.container[key];
}


Map.prototype.toString = function()
{
var str = "";
for (var i = 0, keys = this.keySet(), len = keys.length; i < len; i++) {
str = str + keys[i] + "=" + this.container[keys[i]] + ";\n";
}
return str;
}

以下是用法
// var mapProtocol = new Map();
// map.put("a", "aaa");
// map.put("b","bbb");
// map.put("cc","cccc");
// map.put("c","ccc");
// map.remove("cc");
// var array = map.keySet();
// for(var i in array) {
// document.write("key:(" + array[i] +") <br>value: ("+map.get(array[i])+") <br>");

//}

var onCallback = g_mapProtocol.get(g_intCurProtocol); 

ajax(url, onCallback);

注册协议于方法在map中

g_mapProtocol.put(eGmc2Cockpit_CallText, protocol_CallText);
g_mapProtocol.put(eGmc2Cockpit_Unreach_Notify, protocol_UpdateAllActiveGuard);
g_mapProtocol.put(eGmc2Cockpit_UpdateAllActiveService, protocol_UpdateAllActiveGuard);

protocol_CallText = function (resText)
{
document.getElementById("Label2").innerHTML = resText;
g_intCurProtocol = -1;//这个需要设置回去
}
