You cannot store a value in ViewBag from javascript. ViewBag is a server side concept and exists only on the server. Javascript runs on the client. As far as storing some data from ViewBag into a javascript variable is concerned you could use the following:
您不能通过 javascript 在 ViewBag 中存储值。ViewBag 是服务器端的概念，只存在于服务器端。Javascript 在客户端上运行。至于将 ViewBag 中的一些数据存储到 javascript 变量中，您可以使用以下内容：
<script type="text/javascript">
var foo = @Html.Raw(Json.Encode(ViewBag.FooBar))
</script>
Now this being said I always advice people against using ViewBag/ViewData in ASP.NET MVC. I recommend using strongly typed view and view models. So your code will look like this:
既然如此，我总是建议人们不要在 ASP.NET MVC 中使用 ViewBag/ViewData。我推荐使用强类型视图和视图模型。所以你的代码看起来像这样：
@model MyViewModel
<script type="text/javascript">
var foo = @Html.Raw(Json.Encode(Model))
</script>

You can't. ViewBag is a server-side thing, Javascript runs on client side.
你不能。ViewBag 是服务器端的东西，Javascript 在客户端运行。
