Ajax post 无法与 .net 4 框架结合使用参数中的 html
将我们的项目升级到.net 4.0框架（从3.5开始）后，我们在参数中使用html进行ajax调用时遇到了一些问题。一旦用户在文本区域中输入一些 html，ajax 调用就不再执行。如果用户仅输入纯文本，则没有问题。
<script language="javascript">
/* Doesn't work */
var html = "<p>test</p>";
var body = "default.aspx?html=" + urlEncode(html);
var des = new AJAXInteraction(url, handleResponse, 'saveloader');
des.doPost(body);
/* Work */
var html = "test";
var body = "default.aspx?html=" + urlEncode(html);
var des = new AJAXInteraction(url, handleResponse, 'saveloader');
des.doPost(body);
</script>
有人有什么想法吗？
After upgrading our project to the .net 4.0 framework (from 3.5), we facing some problems with ajax calls with html in the parameters. As soon as the user enters some html in a text area the ajax call isn't executed anymore. If the user enters plain text only, there is no problem.
<script language="javascript">
/* Doesn't work */
var html = "<p>test</p>";
var body = "default.aspx?html=" + urlEncode(html);
var des = new AJAXInteraction(url, handleResponse, 'saveloader');
des.doPost(body);
/* Work */
var html = "test";
var body = "default.aspx?html=" + urlEncode(html);
var des = new AJAXInteraction(url, handleResponse, 'saveloader');
des.doPost(body);
</script>
Anyone any idea?

也许将页面指令中的
validateRequest设置为 false 可以解决您的问题。在您要发布到的页面中执行此操作：默认情况下，ASP.NET 检查 HTML 代码等潜在危险输入的请求并阻止此类请求。请记住，禁用请求验证时您必须自己清理输入！

Probably setting
validateRequestin your page directive to false, will solve your problem. Do this in the Page you're posting to:ASP.NET by default checks requests for potentially dangerous inputs like HTML code and blocks such requests. Keep in mind that you have to sanitize the input yourself when disabling request validation!

在 ASP.NET 4 中，默认情况下，对所有请求启用请求验证，并且忽略每页的 validateRequest 设置。
要恢复 ASP.NET 2.0 请求验证功能的行为，请在 Web.config 文件中添加以下设置：

In ASP.NET 4, by default, request validation is enabled for all requests and the validateRequest setting per page is ignored.
To revert to the behavior of the ASP.NET 2.0 request validation feature, add the following setting in the Web.config file:
