Json解析

HTML5已原生支持json的解析，window.JSON.parse()将json格式字符串转换为json对象，window.JSON.stringify()将json对象转换为json格式字符串。

示例：

<!DOCTYPE HTML>
<html>
<head>
    <title>Window.JSON</title>
    <meta charset="gb18030">
</head>
<body>
    <button type="button" id="btn1">解析json字符串</button>
    <button type="button" id="btn2">json对象转换为json字符串</button>
    <div id="res">
    </div>
    <script language="JavaScript">
    <!--
        var jsonStr = "{\"total\":100,\"data\":[{\"id\":10001,\"name\":\"scott\"},{\"id\":10002,\"name\":\"tiger\"}]}";
        var jsonObj = window.JSON.parse(jsonStr);
        document.getElementById("btn1").onclick = function() {
            var str = "json字符串解析为json对象<br>";
            str += "<span>Total:"+jsonObj.total+"</span><br><span>Data:";
            for (var i=0;i<jsonObj.data.length ; i++)
            {
                str += "id:" + jsonObj.data[i].id + ",name:" + jsonObj.data[i].name+"<br>";
            }
            str += "</span><br>";
            document.querySelector("#res").innerHTML = str;
        }
        document.getElementById("btn2").onclick = function() {
            var jsonObj = {total:100,data:[{id:10001,name:"scott"},{id:10002,name:"tiger"}]};
            var jsonStr = window.JSON.stringify(jsonObj);
            var str = "转为json字符串：<br>" + jsonStr;
            document.querySelector("#res").innerHTML = str;
        }
    //-->
    </script>
</body>
</html>
