一般处理程序：
public void ProcessRequest(HttpContext context)
{
string action = context.Request.Params["action"];
switch (action)
{
case "TestAction":
GetJsonString();
break;
}
context.Response.ContentType = "text/plain";
}
public void GetJsonString()
{
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Sizes = new string[] { "Small" };
List<Product> list = new List<Product>();
for (int i = 0; i < 12; i++)
{
list.Add(product);
}
HttpContext.Current.Response.Write(JsonConvert.SerializeObject(new { Result = 1, Msg = "获取数据成功", Data = list }));
}
第一次加载js：
$(function () {
$.ajax({
type: "get",
url: "/action/Handler.ashx",
data: { action: "TestAction" },
dataType: "json",
success: function (data) {
alert(data.Result);
alert($.isArray( data.Data));
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
alert(textStatus);
}
});
})
