关于js调用内部函数，并返回值（附代码）
var SystemInfo = {
//数据源
dsource: " ",
setSource:function(x)
{
this.dsource = x;
},
getXmlDoc:function()
{
var myAjax = new Ajax.Request(this.dsource,{method: 'get ',onComplete:this.getInfo});
},
getInfo:function(x)
{
return x.responseText;
}
}

SystemInfo.setSource( "http://...... ");
var ret = SystemInfo.getXmlDoc();
alert(ret);

这里面用到了prototype，
但是最后得不到x.responseText...
不知哪里出错，请指正

[解决办法]
var SystemInfo = {
//数据源
dsource: " ",
setSource:function(x)
{
this.dsource = x;
},
send:function()
{
var myAjax = new Ajax.Request(this.dsource,{method: 'get ',onComplete:this.getInfo});
},
getInfo:function(){}
}


//新实例
var dd = new SystemInfo();
dd.setSource( "http://...... ");
//这里实现委托
dd.getInfo = function(res){
alert(res.responseText);//这里添加处理代码
};

dd.send();//发送


OK?
