从asp.net中的Ajax POST检索数据

本文介绍了从asp中的Ajax POST检索数据的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个像这样的ajax帖子

I have an ajax POST like this

$(document).ready(function () { var pcontent = document.body.innerHTML; var url = new URI(); $.ajax({ url: url, type: "POST", data: { "pcontent": pcontent }, success: function (data) { alert($(data).find(".right-panel").html()); }, complete: function () { }, error: function (jqXHR, error, errorThrown) { if (jqXHR.status) { alert(jqXHR.responseText); } else { alert("Something went wrong"); } } }); return false; });

我几乎不困惑如何检索在我的代码后面发布的数据(pcontent).实际上，在特定的类文件中，我需要实现此逻辑.

I am little confused how i could retrieve data (pcontent) that i post here in my code behind.actually in a specific class file i need to implement this logic .

推荐答案

您必须创建一个控制器动作:

You have to create a controller action:

public class HomeController: { // model public class PDocument { public string pcontent {get;set;} } [HttpPost] public ActionResult SaveDocument(PDocument pcontent){ // do something return new JsonResult() { Data = new { Success = true } }; } }

JS:

$.ajax({ url: "Home/SaveDocument", type: "POST", data: { "pcontent": pcontent} ...});

注意:

• 如果已设置，则无需在服务器上创建模型

• You don't need to create a model on server if set

$.ajax({ url: "Home/SaveDocument", type: "POST", data: pcontent }); // server side public ActionResult SaveDocument(string pcontent){ // do some thing }

出于安全原因，您的html必须在调用ajax之前进行编码

For security reason, your html must be encoded before calling ajax
