My attempted methods.
我尝试的方法。
Looking at the JS via browser, the @ViewBag.CCis just blank... (missing)
通过浏览器查看 JS，@ViewBag.CC只是空白...（缺失）
var c = "#" + "@ViewBag.CC";
var d = $("#" + "@ViewBag.CC").value;
var e = $("#" + "@ViewBag.CC").val();
var c = "@ViewBag.CC";
var d = $("@ViewBag.CC").value;
var e = $("@ViewBag.CC").val();

if you are using razor engine template then do the following
如果您使用的是剃刀引擎模板，请执行以下操作
in your view write :
在你看来写：
<script> var myJsVariable = '@ViewBag.MyVariable' </script>
UPDATE:A more appropriate approach is to define a set of configuration on the master layout for example, base url, facebook API Key, Amazon S3 base URL, etc ...```
更新：更合适的方法是在主布局上定义一组配置，例如基本 url、facebook API 密钥、Amazon S3 基本 URL 等......```
<head>
<script>
var AppConfig = @Html.Raw(Json.Encode(new {
baseUrl: Url.Content("~"),
fbApi: "get it from db",
awsUrl: "get it from db"
}));
</script>
</head>
And you can use it in your JavaScript code as follow:
你可以在你的 JavaScript 代码中使用它，如下所示：
<script>
myProduct.fullUrl = AppConfig.awsUrl + myProduct.path;
alert(myProduct.fullUrl);
</script>

ViewBagis server sidecode.Javascriptis client sidecode.
ViewBag是服务器端代码。Javascript是客户端代码。
You can't reallyconnect them.
你无法真正连接它们。
You can do something like this:
你可以这样做：
var x = $('#' + '@(ViewBag.CC)').val();
But it will get parsed on the server, so you didn't really connect them.
但是它会在服务器上被解析，所以你并没有真正连接它们。
