如何从 ViewBag 中获取 bool 值？

Question

I am trying to receive bool values from ViewBag.

But the issue is that to receive value I am using:

var test = '@ViewBag.Test'

In this way value will be 'True' or 'False' (string). Of cource I can use something like if (test == 'True') but, is there a way to get from ViewBag bool value dirrectly, or at least convert it?

EDIT:

I need to get ViewBag value in javascript part.

Answer 1

In controller code is ViewBag.Test = true;

In View code is

var test=@(ViewBag.Test.ToString().ToLower());
console.log(test);

Now the data type of variable test is a bool. So you can use:

if(test)
    alert('true');
else 
    alert('false')

Answer 2

You could use unboxing:

@((bool)(ViewBag.Test??false))

This provides a default value (false) if Test does not exist in the ViewBag and typecasts the result.

Answer 3

If your value is bool in controller then use cshtml page

bool test='@ViewBag.Test';

As viewbag needs not casting I think when you assign your value in a bool variable it gives you bool value in your view(cshtml) page

Answer 4

您只需要删除引号var test = @ViewBag.Test

Answer 5

Only need:

<script>
   var test = '@ViewBag.Test';
   if(test)
       {console.log(test);}
   else
       {console.log(test);};
</script>
