javascript – 如何在角度使用npm模块？

npm模块,因为当我尝试将其包含在模板中时出现错误：

<script src="https://js.braintreegateway.com/v2/braintree.js"></script>

我有一个名为billing的状态,我用它来路由到我的模板,控制器’BillingController’.我希望能够注入braintree-web和myscript.js：

<script>
  braintree.setup(
          // Replace this with a client token from your server
          clientToken,
          "dropin", {
            container: "payment-form",
            form: "checkout",
          });
</script>

请帮忙.我怎样才能做到这一点？

编辑：

目前,这是我的最底层

<!-- braintree sdk -->
    <script src="https://js.braintreegateway.com/v2/braintree.js"></script>

    <!-- braintree setup -->
    <script>
      var clientToken = removed;
      braintree.setup(
          // Replace this with a client token from your server
          clientToken,
          "dropin", {
            container: "payment-form",
            form: "checkout",
          });
    </script>

这些是我得到的错误：

看起来像braintree脚本没有加载(？)

谢谢您的帮助

这是角度特殊的模块.然后你应该创建像app.js这样的文件并粘贴这段代码：

var yourApp = angular
  .module('yourApp', ['braintree-angular'])
  .constant('clientTokenPath', '/path-or-url-to-your-client-token');

例如：

(function () {
    'use strict';

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

    app.constant('clientTokenPath', '/path-or-url-to-your-client-token');

    app.config(['$interpolateProvider', function ($interpolateProvider) {
        $interpolateProvider.startSymbol('[[');
        $interpolateProvider.endSymbol(']]');
    }]);


}());

你的controller.js可能是这样的：

(function() {
    'use strict';

    angular
            .module('yourModuleName')
            .controller('DashboardCtrl', DashboardCtrl);

    DashboardCtrl.$inject = ['$scope', '$braintree'];

    function DashboardCtrl($scope, $braintree) {

        var client;
        $scope.creditCard = {
            number: '',
            expirationDate: ''
        };

        var startup = function() {
            $braintree.getClientToken().success(function(token) {
                client = new $braintree.api.Client({
                    clientToken: token
                });
            });
        };

        $scope.payButtonClicked = function() {

            // - Validate $scope.creditCard
            // - Make sure client is ready to use

            client.tokenizeCard({
                number: $scope.creditCard.number,
                expirationDate: $scope.creditCard.expirationDate
            }, function (err, nonce) {

                // - Send nonce to your server (e.g. to make a transaction)

            });
        };

        startup();

    }


}());

请注意,app.js应该包含在其余的控制器,工厂和服务之前,以及在angular.js和braintree.js库之后.
