json等于后台回调来的字符串,我想取key和value.怎样取呀. 谢谢

[whatpn]

后台方法
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string show2()
{
return "{ \"options\": \"[{\"text\":\"王家湾\",\"value\":\"9\"},{\"text\":\"李家湾\",\"value\":\"10\"},{\"text\":\"邵家湾\",\"value\":\"13\"}]\" }";
}


前台
$.ajax({
url: "test.asmx/show2",
type: "post",
dataType: "json",
contentType: "application/json;charset=utf-8",
data: "{}",
success: function(data) {
var json = data;
alert(json);
for (var i in json) {
alert(json[i]);
}
},
error: function(msg) {
alert("出错了！");
}
});


json[i] 返回的值

{"Table":[{"id":"1","name":"宏仁"},{"id":"2","name":"建滔"},{"id":"3","name":"星源航天"},{"id":"4","name":"建滔 3"},{"id":"5","name":"test"},{"id":"6","name":"宏仁"},{"id":"7","name":"生益"}]}
