How to pass an AngularJS variable to a script tag within an HTML view

Here's a dilemma I'm facing. I have a third-party script that needs to be integrated into my AngularJS application, within the HTML using a <script> tag. My goal is to pass scope variables (such as name and email) to this script. Initially, I am exploring if it's possible to pass a scope variable from the controller to a script tag during page load. Alternatively, I consider transforming the script into a template, but I am unsure of the best approach. I am concerned that even if I manage to achieve the basic concept, the script tag might render actual data before the variable is successfully passed.

Below is the snippet of HTML:

  <body>
    <div ng-controller="MainCtrl">
        Angular variable: {{foo}}
    </div>
  </body>
  <script type="text/javascript">
    console.log(foo); // Is it $scope.foo?
  </script>

This is how the controller is set up:

var app = angular.module('app', []);

app.controller('MainCtrl', function($scope) {
      $scope.foo = 'bar';
})

Answer №1

If you're looking to integrate a third-party script (such as a jQuery plugin) into your AngularJS application, it's important to create a wrapper for that script in the form of a directive or component.

Simply including the script won't suffice - trust me on this.

I stumbled upon a helpful example that demonstrates how to create an AngularJS directive to encapsulate a simple jQuery plugin:

<html>
<head>
    <title>AngularJS wrapping jQuery plugin</title>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script src="https://raw.github.com/SamWM/jQuery-Plugins/master/numeric/jquery.numeric.js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js"></script>

    <script type="text/javascript">
        var app = angular.module('myApp', []);
        app.directive('numberMask', function() {
            return {
                restrict: 'A',
                link: function(scope, element, attrs) {
                    $(element).numeric();
                }
            }
        });
    </script>
</head>

<body>
    <div ng-app="myApp">
        <div>
            <input type="text" min="0" max="99" number-mask="" ng-model="message"> 
        </div>
    </div>

</body>
