Question

When passing boolean value from controller to the view using ViewData, how do I retrieve it as a boolean value in javascript?
example:

Controller:

ViewData["login"] = true;

View

    <script type="text/javascript">
var login = <%= (bool)ViewData["Login"] %>;   /// this doesn't work, throw javascript error;
</script>

yeh surely i can do

  <script type="text/javascript">
var login = '<%= ViewData["Login"] %>';   /// now login is a string 'True'
</script>

But i rather keep login object as a boolean rather a string if that’s possible.

Just remove the single quotes.

<script type="text/javascript">
    var login = <%= (bool)ViewData["Login"] ? "true" : "false" %>;
</script>

This will result in:

var login = true;

Which will be parsed as a boolean in the browser.
