【加急！！】json转成数组，求高手指教，在线等...
aspx中有一个json对象msg，代码如下：
$.ajax({
type: "POST",
url: "UserExists.ashx",
//用text接收
dataType: "text",
data: "userId=loadTiemTree",
success: function (msg) {
var $form = $("form");
if (msg != null && msg != "") {
//把msg转换成数组

//显示后台数据
$form.append("<div style=\"width:1000px;margin:0px auto;\"><div style=\"width:495px;float:left;border:1px outset red;\">"
+ msg + "</div></div>");
$("#page_tag_load").hide();

} else {
$("#page_tag_load").hide();
}
}
});

输出后的结果如下：
[{"newid":"673"},{"newimg":"~/Sources/Image/treetime/20121010205839534.jpg"},{"newcontent":""}",{"newsclick":"0"},{"newtime":"2012/10/10 20:58:36"}][{"newid":"672"},{"newimg":"~/Sources/Image/treetime/20121010205844616.jpg"},{"newcontent":""}",{"newsclick":"0"},{"newtime":"2012/10/10 20:58:19"}][{"newid":"671"},{"newimg":"~/Sources/Image/treetime/20121010205713751.jpg"},{"newcontent":""}",{"newsclick":"0"},{"newtime":"2012/10/10 20:57:53"}][{"newid":"670"},{"newimg":"~/Sources/Image/treetime/20121010205758428.png"},{"newcontent":""}",{"newsclick":"0"},{"newtime":"2012/10/10 20:57:31"}]
我想在页面上把它转成数组，然后获取数组里面的信息赋给控件，该怎么做啊，求高手指教，在线等。


[解决办法]
一般是使用
eval(msg)

你的数据不规范

{"newcontent":""}",
这里有多余的"


正确格式可以这样

JScript code

<script type="text/javascript">  msg = '[{"newid":"673"},{"newimg":"~/Sources/Image/treetime/20121010205839534.jpg"},{"newcontent":""},{"newsclick":"0"},{"newtime":"2012/10/10 20:58:36"}][{"newid":"672"},{"newimg":"~/Sources/Image/treetime/20121010205844616.jpg"},{"newcontent":""},{"newsclick":"0"},{"newtime":"2012/10/10 20:58:19"}][{"newid":"671"},{"newimg":"~/Sources/Image/treetime/20121010205713751.jpg"},{"newcontent":""},{"newsclick":"0"},{"newtime":"2012/10/10 20:57:53"}][{"newid":"670"},{"newimg":"~/Sources/Image/treetime/20121010205758428.png"},{"newcontent":""},{"newsclick":"0"},{"newtime":"2012/10/10 20:57:31"}]'.replace(/\]\[/g, "],[");  arr = eval('new Array(' + msg + ')');  for (i = 0; i < arr.length; i++) {    alert(arr[i][0].newid);    alert(arr[i][1].newimg);  }</script>
