从JavaScript在ViewBag存储值 [英] Store a value in ViewBag from javascript

问题描述

我怎么能存储在ViewBag从JavaScript访问它的值？

How can I store a value in the ViewBag accessing it from javascript?

推荐答案

您可以不是一个值ViewBag从JavaScript存储。 ViewBag是一个服务器端的概念，只存在于服务器上。的Javascript运行在客户端上。至于从ViewBag一些数据存储到一个javascript变量而言，你可以使用下列内容：

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:

<script type="text/javascript">
    var foo = @Html.Raw(Json.Encode(ViewBag.FooBar))
</script>

现在这是说我总是建议人们反对ASP.NET MVC使用ViewBag / ViewData的。我建议使用强类型的视图，视图模型。所以，你的code将是这样的：

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:

@model MyViewModel
<script type="text/javascript">
    var foo = @Html.Raw(Json.Encode(Model))
</script>
