Is there a way to send a Razor boolean variable to an Angular directive?

Within my cshtml file, I am working with a boolean variable. However, when attempting to pass this variable to my Angular directive, it is being received as "False" rather than "false". Even hardcoding it to be "false" in lowercase does not solve the issue.

This is how my cshtml file looks:

@{
    var myVar = false;
}

<some-directive test="@myVar"></some-directive>

The Angular directive I am using for testing purposes has the following structure:

angular.module('someApp')
  .directive('someDirective', function () {
      return {
          restrict: 'E',
          scope: {
              test: '@'
          },
          link: function ($scope, element, attrs) {

              console.log($scope.test) // False
              console.log(!$scope.test) // false
              console.log(!!$scope.test) // true
          }
      }
  });

If you're looking for part of the solution, check out this link here.

For Angular specifically, make sure to use a directive variable like test: '=' instead of test: '@'. This way, your variable will be recognized as a boolean value "false" rather than just the text "false".

In your Razor file, consider using the following code snippet to convert from "False" to "false":

@{
    var myRazorVar = false;
}

<some-directive test="@myRazorVar.ToString().ToLower()"></some-directive>
@* or *@
<some-directive test="@Json.Encode(myRazorVar)"></some-directive>

Answer №2

Due to the case sensitivity of both languages and their varying patterns for Booleans (even in numbers), a solution is:

<specific-instruction test="@Json.Encode(myVar)"></specific-instruction>  

This will properly convert C# data to JavaScript format.

Answer №3

Make sure to use '=' instead of '@' in your scope definition.

angular.module('myApp')
  .directive('myDirective', function () {
      return {
          restrict: 'E',
          scope: {
              value: '='
          },
          link: function ($scope, element, attrs) {

              console.log($scope.value) // false
              console.log(!$scope.value) // true
              console.log(!!$scope.value) // false
          }
      }
  });

After some trial and error, I managed to make it function with the following code:

const serializedData = JSON.stringify(Model.ReplicateReopeningClientFiles);
