Items是一个数组，还得访问下标。colObj["Items"][0]["topid"]
colObj.Items 是一个数组
for (var i = 0; i < colObj.Items.length; i++) {
    var item = colObj.Items[i];
    var name = item.name;
    var topid = item.topid;
    // ...
}

打开网页慢死了大叔抢了我的SF其实jQuery和js在访问数组上面应该没有问题的吧
贴图：DEMO下载：http://www.codefans.net/soft/5582.shtml我要取的值是这个特效列表里选定后的值呀。
colObj["Items"][0]["topid"]确实能取到但是我取这个没用呀，用户选择后要发到服务器上，如何知道用户选择的ID呢？？？？
{"name":"菜单项目标题1","topid":"0","colid":"1","value":"菜单项目标题1","fun":function(){}},  有个回调函数"fun",但是这个怎么用啊
LZ 这样获取各个菜单的值，<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

]};function ShowText(){
var l=colObj["Items"].length;
var str='各个菜单的各个值如下\n';
for(var i=0;i<l;i++){
str+='第 '+i+ ' 个菜单, 的 ';
str+=' name 值 = '+colObj["Items"][i]["name"]+' , ';
str+=' topic 值 = '+colObj["Items"][i]["topid"]+' , ';
str+=' colid 值 = '+colObj["Items"][i]["colid"]+' , ';

str+=' fun 值 = '+colObj["Items"][i]["fun"]+' , ';
str+='\n';
}
alert(str);
}
ShowText();

<p>获取各个菜单的值...</p><a href="javascript:ShowText();">show the menu TEXT </a>
