如果你确实有合法的需要从一个部分运行一些js，这里是你可以做到的，jQuery是必需的:

<script type="text/javascript">        
    function scriptToExecute()
    {
        //The script you want to execute when page is ready.           
    }

    function runWhenReady()
    {
        if (window.$)
            scriptToExecute();                                   
        else
            setTimeout(runWhenReady, 100);
    }
    runWhenReady();
</script>

OP的目标是将内联脚本定义到他的Partial View中，我假设这个脚本仅特定于该Partial View，并将该块包含到他的脚本部分中。

我明白他想要局部视图是独立的。这个想法类似于使用Angular时的组件。

我的方法是将脚本原样保存在Partial View中。现在的问题是，当调用Partial View时，它可能会在所有其他脚本(通常被添加到布局页面的底部)之前执行脚本。在这种情况下，您只需让Partial View脚本等待其他脚本。有几种方法可以做到这一点。我之前用过的最简单的方法是在body上使用事件。

在我的布局中，我会在底部有这样的东西:

// global scripts
<script src="js/jquery.min.js"></script>
// view scripts
@RenderSection("scripts", false)
// then finally trigger partial view scripts
<script>
  (function(){
    document.querySelector('body').dispatchEvent(new Event('scriptsLoaded'));
  })();
</script>

然后在我的局部视图(在底部):

<script>
  (function(){
    document.querySelector('body').addEventListener('scriptsLoaded', function() {

      // .. do your thing here

    });
  })();
</script>

另一种解决方案是使用堆栈来推送所有脚本，并在最后调用每个脚本。其他解决方案，如前所述，是RequireJS/AMD模式，它也非常有效。

如果你确实有合法的需要从一个部分运行一些js，这里是你可以做到的，jQuery是必需的:

<script type="text/javascript">        
    function scriptToExecute()
    {
        //The script you want to execute when page is ready.           
    }

    function runWhenReady()
    {
        if (window.$)
            scriptToExecute();                                   
        else
            setTimeout(runWhenReady, 100);
    }
    runWhenReady();
</script>

这是一个很常见的问题，所以我会把我的答案贴出来。

我也遇到过同样的问题，虽然它不是理想的，但我认为它实际上工作得很好，并且不使部分依赖于视图。

我的场景是，一个动作本身是可访问的，但也可以嵌入到一个视图中——一个谷歌映射。

在我的_layout中我有:

@RenderSection("body_scripts", false)

在我的索引视图中有:

@Html.Partial("Clients")
@section body_scripts
{
    @Html.Partial("Clients_Scripts")
}

在我的客户视图中，我有(所有的地图和assoc。html):

@section body_scripts
{
    @Html.Partial("Clients_Scripts")
}

我的Clients_Scripts视图包含要呈现到页面上的javascript。

通过这种方式，我的脚本是隔离的，并且可以在需要的地方呈现到页面中，而body_scripts标记只在razor视图引擎第一次发现它时呈现。

这让我把所有东西都分开了——这对我来说是一个很好的解决方案，其他人可能有问题，但它确实修补了“设计”的漏洞。

假设您有一个称为_contact的部分视图。Cshtml，您的联系人可以是合法的(姓名)或物理主体(名，姓)。你的视图应该关心被渲染的内容，这可以用javascript实现。所以延迟渲染和JS内部视图可能需要。

我认为唯一可以忽略它的方法是，当我们创建一种不引人注目的方式来处理这种UI关注点时。

还要注意MVC 6将有一个所谓的视图组件，甚至MVC未来也有一些类似的东西，Telerik也支持这样的东西…

从这个线程中的解决方案，我提出了以下可能过于复杂的解决方案，让你延迟渲染任何html(脚本)在一个using块。

使用

创建section

Typical scenario: In a partial view, only include the block one time no matter how many times the partial view is repeated in the page: @using (Html.Delayed(isOnlyOne: "some unique name for this section")) { <script> someInlineScript(); </script> } In a partial view, include the block for every time the partial is used: @using (Html.Delayed()) { <b>show me multiple times, @Model.Whatever</b> } In a partial view, only include the block once no matter how many times the partial is repeated, but later render it specifically by name when-i-call-you: @using (Html.Delayed("when-i-call-you", isOnlyOne: "different unique name")) { <b>show me once by name</b> <span>@Model.First().Value</span> }

渲染“sections”

(即在父视图中显示延迟的部分)

@Html.RenderDelayed(); // writes unnamed sections (#1 and #2, excluding #3)
@Html.RenderDelayed("when-i-call-you", false); // writes the specified block, and ignore the `isOnlyOne` setting so we can dump it again
@Html.RenderDelayed("when-i-call-you"); // render the specified block by name
@Html.RenderDelayed("when-i-call-you"); // since it was "popped" in the last call, won't render anything due to `isOnlyOne` provided in `Html.Delayed`
