用jQuery的$.each方法无法解析WebServers返回的JSON
通过jQuery的Ajax方法获取到WebServers返回的JSON数组，但是通过each方法解析时，获得的数据始终是undefined.
通过FireBug查看返回的数据是正确的，数据内容是：{"d":"[{id:2,Name:\u0027维生素A\u0027,Introduction:\u002712466说\u0027,Time:\u00272012/10/7 19:27:00\u0027}]"} 通过json.d也可以获取到数据，就是使用each方法无法遍历，在遍历的时候，用alert(this)，显示的数据和json.d显示的一样，感觉完全没有分拆样
代码如下
Websevers代码
public string NutrientsList()
{
string result = string.Empty;
IList<NutrientsInfo> info = new List<NutrientsInfo>();
info = nut.INutrientsAllList();
if (info.Count < 1)
{
result = "null";
}
else
{
result = "[";
for (int i = 0; i < 1; i++)
{
result += "{id:" + info[i].ID + ",Name:\'" + info[i].Name + "\',Introduction:\'" + info[i].Introduction + "\',Time:\'" + info[i].CreatTime + "\'}";
result += ",";
}
result = result.TrimEnd(',');
result += "]";
}
return result;
}
$.ajax({
type: "POST",

beforeSend: function () {
$("#NutrientsList").empty().html("<div style="text-align:center">正在读取菜谱！<\/div>");
},
success: function (result) {
if (result == "null") {
$("#NutrientsList").empty().html("<div style="text-align:center">没有找到营养素！<\/div>");
}
