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.

  • show, how you set this variable – Backs Aug 19 '15 at 08:43

    Use a viewmodel instead of a viewbag. it's a slight bit more overhead to set up since you need to define everything in a class, but will save your sanity in the long run. are you trying to use the variable in JS or in razor? – user1666620 Aug 19 '15 at 08:45
  • In js. In perspective yes, it will be changed to model, but right now, I need ViewBag. – Olegs Jasjko Aug 19 '15 at 08:49
  • Can't you just change `var test = '@ViewBag.Test';` to `var test = @ViewBag.Test;` ? – Fabjan Aug 19 '15 at 09:06

You could use unboxing:

var test = @((bool)(ViewBag.Test??false))

Condensed into single line, handles missing ViewBag element.
Null coalescing operator returns the value of ViewBag.Test or false if "Test" doesn't exist. Finally value is typecast.

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')

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

You simply need to remove quotes var test = @ViewBag.Test

Only need:

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