json前台解析list<实体>问题
$.ajax({
type: "POST",
contentType: "application/json",
url: "gorg.aspx/select",
data: "{time:'" + date + "',grogid:'" + parastr + "'}",
dataType: 'json',
success: function (list) {
$(list.d).each(function () {
//alert(list.id, function (i, item) {
//alert(list.Id);
//$('#id1').append(this.toString() + " ");
//alert(list.d.join(" | ").grogid);
});

// jQuery.each(list.time, function (i, item) {
// alert(item.time + "," + item.grogid);
// });
}
});

------解决方案--------------------
什么问题？
list返回的什么内容，楼主要实现什么效果？
------解决方案--------------------
success: function (list) {
data = jQuery.parseJSON(list.d); /*这里是否解析要看后台返回的数据格式，如果不返回表名则无需要 parseJSON */
t = "<table border='1'>";
$.each( function (i, item) {
t += "<tr>";
t += "<td>" + item.UserId + "</td>";
t += "<td>" + item.UserName + "</td>";
t += "</tr>";
})
t += "</table>";
$("#result").html(t);
}
------解决方案--------------------
是自定义的
完整的例子，可以直接拷贝粘贴运行的，。需要.net 3.5之后的版本
