Html没有正确呈现，并且没有使用Ajax.ActionLinks设置Viewbag.Title [英] Html not correct rendered and no Viewbag.Title is set using Ajax.ActionLinks
问题描述
_ViewStart.cshtml
@{
Layout = Request.IsAjaxRequest() ? null : "~/Views/Shared/_Layout.cshtml";
}
_Layout.cshtml
...
</head>
<body>
<div id="NavigationPanel">
@{ AjaxOptions options = new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "ContentPanel",
OnBegin = "OnBeginAnimateContentPanel",
OnComplete = "OnCompleteAnimateContentPanel",
};}
<div>
<p>@Ajax.ActionLink("Users", "Index", "User", options)</p>
<p>@Ajax.ActionLink("Groups", "Index", "Group", options)</p>
<p>@Ajax.ActionLink("Permissions", "Index", "Permission", options)</p>
</div>
</div>
<div id="ContentPanel">
@RenderBody()
</div>
</body>
</html>
Global.Asax.cs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Main", action = "Index", id = UrlParameter.Optional }
);
}
MainController.Index操作：
public ActionResult Index()
{
return View();
}
主视图Index.cshtml
@{
ViewBag.Title = "Test-Index";
}
this is the Index View of the MainController
用户/组/权限控制器的索引视图+操作类似于MainController的索引。标题设置为ViewBag和一些小测试文本。
The Index View + Action for the User / Group /Permission Controller are like the Index of the MainController. A Title is set to the ViewBag and some little test text.
这里有一个问题。
当我单击其中一个Ajax.ActionLInks时，虽然View在#ContentPanel中正确呈现，但每个视图的标题（用户/组/权限）永远不可见...但是当我检查html源代码时：
The title of each View (User/Group/Permission) is never visible although the View is rendered correctly in the #ContentPanel when I click one of those Ajax.ActionLInks...BUT when I check the html source code:
ContentPanel中的内容是索引视图中的内容???
The content in the ContentPanel is the one from the Index View ???
为什么是这样以及如何我可以为每个Ajax.ActionLink设置我的View标题吗？
<body>
<div id="NavigationPanel">
<p><a data-ajax="true" data-ajax-begin="OnBeginAnimateContentPanel" data-ajax-complete="OnCompleteAnimateContentPanel" data-ajax-mode="replace" data-ajax-update="#ContentPanel" href="/User">Users</a></p>
<p><a data-ajax="true" data-ajax-begin="OnBeginAnimateContentPanel" data-ajax-complete="OnCompleteAnimateContentPanel" data-ajax-mode="replace" data-ajax-update="#ContentPanel" href="/Group">Groups</a></p>
<p><a data-ajax="true" data-ajax-begin="OnBeginAnimateContentPanel" data-ajax-complete="OnCompleteAnimateContentPanel" data-ajax-mode="replace" data-ajax-update="#ContentPanel" href="/Permission">Permissions</a></p>
</div>
<div id="ContentPanel">
this is the text within the Index View of the MainController
</div>
</body>
推荐答案
当您查看来源时，您正在查看最初加载的来源;通过AJAX加载的内容不会出现。但是，如果使用DOM检查器，它将显示动态加载的内容。至少这是它在Chrome中的工作方式;我想其他浏览器是相同的。
When you view source, you're looking at the source that initially loaded; content loaded via AJAX will not appear. However, if you use the DOM inspector, it will show dynamically loaded content. At least this is the way it works in Chrome; I imagine other browsers are the same.
检查DOM检查器，看看代码是否符合预期（在Chrome和Firefox上右键单击Inspect element） ）。
Check the DOM inspector, and see if the code is what you expect (right-click, "Inspect element" on Chrome and Firefox).
至于设置标题，用AJAX无法完成，至少没有一些Javascript帮助。在部分视图中，请尝试以下Javascript：
As for setting the title, that can't be done with AJAX, at least not without some Javascript help. In your partial views, try the following Javascript:
<script>
document.title = "My New Title Here";
</script>
