应为ajax里面经常会用json方式传数据，所以组合成json方式
<html>
<head>
<title></title>
<script language="javascript" type="text/javascript">
/*对象*/
var obj = {
"30001":{"name":"小明","age":25},
"00001":{"name":"张三","age":30}
};
/*一方式*/
var first = obj["30001"];
var second= obj["00001"];
//alert(first.name)
/*二方式*/
for(var i in obj){
// alert(obj[i].name)
}
/*字符串模拟json对象*/
/*定义json数据格式,用eval把json原本的字符串转换成对象*/
var json = "({\"30001\":{\"name\":\"小明\",\"age\":25},\"00001\":{\"name\":\"张三\",\"age\":30}})";
var jsonObj = eval(json);
alert("json对象里面name值："+jsonObj["30001"].name)
</script>
</head>
<body>
</body>
</html>
