分步说明:
新建 Asp.Net MVC2 项目
型号:
public class TestModel
{
public int Property
{ get; set; }
}
家庭 Controller :
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(TestModel model)
{
return Content(model.Property.ToString());
}
}
索引.aspx:
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MVCTest.Models.TestModel>" %>
<!DOCTYPE html>
<script type="text/javascript" src="<%=Url.Content("~/Scripts/MicrosoftAjax.js")%>"></script>
<script type="text/javascript" src="<%=Url.Content("~/Scripts/MicrosoftMvcAjax.js")%>"></script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Index</title>
</head>
<body>
<%using( Ajax.BeginForm( "index", "home", new AjaxOptions()
{
HttpMethod = "Post",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "Result"
} ) ){ %>
<div class="editor-field">
<%=Html.TextBoxFor(model => model.Property, new {@type = "number", @step = "1"})%>
<%=Html.ValidationMessageFor(model => model.Property)%>
</div>
<button type="submit" value="click Me">Click Me</button>
<% } %>
<div id="Result">
</div>
</body>
</html>
鉴于 mvc 应用程序拒绝在 Chrome/Safari 浏览器中正常工作 - 我收到
model.Property == 0 在我发布的 Controller 方法中。
当我删除 html5 属性时，更改:
<%=Html.TextBoxFor(model => model.Property, new {@type = "number", @step = "1"})%>
到
<%=Html.TextBoxFor(model => model.Property)%>
它按预期工作。
那么从 Chrome/Safari 的角度来看，我的带有 html5 属性的 ajax 表单有什么问题？ IE/FF 浏览器在任何情况下都能正常工作。

只是为了比较 - IE 中的 ajax 请求:

Accept: */*
Accept-Language: ru

x-requested-with: XMLHttpRequest, XMLHttpRequest

显然，由于某些未知原因，Chrome/Safari 和 IE/FF 中的请求有所不同。有什么想法吗？
最佳答案
开发了一些解决方法 - 迁移到 MVC3 ，在 web.config 中启用了 UnobtrusiveJavaScript，如下所示:
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
然后丢弃对 MicrosoftAjax.js 和 MicrosoftMvcAjax.js 的引用，而是使用这些引用:
<script type="text/javascript" src="<%=Url.Content("~/Scripts/jquery-1.4.4.min.js")%>"></script>
<script type="text/javascript" src="<%=Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")%>"></script>
解决了问题，但对我来说它看起来像是一个错误，我会向 MS 报告它。
