AJAX一般处理程序

1、

前台调用AJAX方法和返回处理：

<script type="text/javascript">
function Tpfb(wzfbID) {
$.messager.confirm("系统提示", "您确定要发布吗？", function (r) {
if (r) {
$.ajax({
cache:false,
type: "GET",
url: ‘TP_WZFB.ashx?HandlerType=WZFB&FBWZID=‘ + wzfbID + ‘&TITLE=‘ + $("#txtTitle").val(),
dataType: ‘json‘,
success: function(data)
{
if (data.State == "1")
{
$.messager.alert("系统提示", "发布成功!");
parent.location.href = parent.location.href;
}
else
$.messager.alert("系统提示", data.Message, "error");
}
});
}
});
}
</script>

2、ASHX（一般处理程序文件）的参数接收和处理方法：

//接收

public override void OnRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string strContext = "";
string HandlerType = context.Request["HandlerType"];
switch (HandlerType)
{
case "WZFB":
strContext = Tpfb(context);
break;
default:
break;
}
context.Response.Write(strContext);
}

//处理方法

private string Tpfb(HttpContext context)
{
//投票信息ID
string fbwzID = context.Request["FBWZID"];

return Hzjg.GlobalExpand.ToJson(oMes);//结果要返回JSON格式字符串，与前台调用AJAX保持一致

}
