Passing information from Razor client (cshtml) to AngularJS

Question

I have the following razor file:

@{
    ViewBag.Title = "Blah";
    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.InitModule = "myFooModule";
}

@section Scripts{
    <script src="~/Scripts/angular-route.js"></script>
    <script src="~/Scripts/angular-route.min.js"></script>
    <script src="~/js/recipes.js"></script>
}
<div data-ng-view

Here is my angularjs code:

var testModule = angular.module("myFooModule", ['ngRoute']);

appetizerModule.config(["$routeProvider", function ($routeProvider) {
    $routeProvider.when("/", {
        controller: "myController",
        templateUrl: "/Templates/test.html"
    });
    $routeProvider.otherwise({ redirectTo: "/" });
}]);

I would like to pass a variable with data like "myuserinfofromPage" from my razor page to my angularJs so that I can use that data ("myuserinfofromPage") to perform certain set of operations. I am struggling to get a clean way to pass data as I am new to AngularJS. What's the best way to pass simple data from Razor(cshtml) to my Angular code?

Solution 1

You could embed the following in your razor page:

 <script>
  app.value('myValue', @Html.Raw(Json.Encode(Model)))
 <script>

Where Model is a .NET object you want to render.

Then inject it into your controller:

 app.controller('ctrl', function($scope, myValue) 
 {
      //use myValue
 });

Solution 2

You can pass data in json format to you view and after bootstrap your data using factory ie:

testModule.factory('UserService', function () {

      var _userInfo= @Html.Raw(ViewBag.UserDataInJsonFormat); //<- your data is going here

      return {
      userInfo : _userInfo

      }

}

Thanks pixelbits and sylwester for your responses. I have used angular directives to pass the element data and stored it in $scope variable in my angular controllers. Reference: fdietz.github.io/recipes-with-angular-js/directives/…

This worked perfectly. Thank you! Just what I needed!

Does it matter if it is _Layout or View?

@sylwester I am getting Unexpected token @ in JSON at position 0. Is there anything additional needed?

@stevek it looks like you have got not valid json
