本文介绍了使用JavaScript遍历对象和map集合的方法。首先通过for...in循环遍历map集合中的键值对，并展示了如何访问每个元素。接着演示了如何遍历包含多个对象的数组列表，对每个对象进行操作。

//首先你要遍历的东西是一个对象，如['name':''zhangsan','key':'mongy']，如果是字符串形式的应该先eval下

1 .遍历map集合

var data =[{"ccac8078-07a6-46c9-b450-b696db1a6f99":"qsss","01":"wlc","name":"wlc"}];
    var map = data[0];
    for (var key in map) {
              alert("map["+key+"]"+map[key]);
          }

2，遍历对象

var list = [{"cid":"c3e1109c-5279-4cd3-a5c6-36f31e94b78e","cloginname":"yuxiaojie","cpassword":"123","cremark":"ww","cstatus":"\u0000","ctype":"\u0000","cusername":"wangalichao","dcreatedatetime":null,"dmodifydatetime":null},{"cid":"ccac8078-07a6-46c9-b450-b696db1a6f99","cloginname":"qsss","cpassword":"w","cremark":"www","cstatus":"\u0000","ctype":"\u0000","cusername":"w","dcreatedatetime":null,"dmodifydatetime":null}];

for (var i in list) {
alert(list[i]);
}
