jquery $.ajax 获取josn数据

    <script type="text/javascript" src="jquery-1.9.1.js"></script>
    <script type="text/javascript">
        function test() {
            $.ajax({
                type: "get",
                cache: false,
                url: "../../ajax/Task.aspx",
                data: ‘id =1‘, // URL后面参数
                success: function (json) {
                    json = eval("(" + json + ")");
                    $.each(json, function (i, item) {

                        alert(parseInt(item.iname), parseInt(item.iid));
                    });
                },
                error: function (msg) {
                    alert("错误：" + msg);
                }
            });
        }
    </script>

后台代码:
public void ProcessRequest(HttpContext context)//只是大概个例子 为了学习
{
        context.Response.ContentType = "application/json";
        string[] Arraya = new string[] { "张三", "李四", "王二", "赵五" };
        string returns = "";
        returns = "{\"people\":[";
        for (int i = 0; i < Arraya.Length; i++)
        {
            returns += "[{\"iname\":\"" + Arraya[i] + "\",\"iid\":\"001\"}]" + (i != (Arraya.Length - 1) ? "," : "");
        }
        returns += "]};";
        context.Response.Write(returns);//返回之后 就是上面js里直接定义的json格式
    }
