将PayPal Checkout Button 用作Angular.js 元素指令时，如何设置它的style选项？

this.paypal = {
  // ...
  style: {
    color: 'black',
    shape: 'rect'
  }
}

似乎style无法在绑定中传递该选项，style因为这已经是保留HTMLElement属性？

<paypal-button
  client="$ctrl.paypal.client"
  commit="true"
  env="$ctrl.paypal.env"
  style="$ctrl.paypal.style"
  on-authorize="$ctrl.paypal.onAuthorize"
  on-cancel="$ctrl.paypal.onCancel"
  payment="$ctrl.paypal.payment">
</paypal-button>

明白了，你必须使用ng-attr-style="$ctrl.paypal.style"它，它会起作用。

ng-attr-style允许您评估表达式，而不是解释style该输入元素属性的字符串文字。完整的解释可以在标题“ ngAttr用于绑定到任意属性”下找到。

请参阅plnkr 链接以获取在指令内的 paypalbutton 上应用样式的工作代码

您可以将整个贝宝变量传递给控制器​​范围内的指令。

scope: {
    paypal: '='
},

然后你可以将变量绑定到模板

<test-directive paypal="$ctrl.paypal"></test-directive>


(function() {
      var app = angular.module("myApp", ['ui.bootstrap', 'paypal-button']);
      app.controller('testCtrl', ['$scope', function($scope) {
        var $ctrl = this;
        $ctrl.paypal = {
          env: 'sandbox',

          client: {
            sandbox: 'AWi18rxt26-hrueMoPZ0tpGEOJnNT4QkiMQst9pYgaQNAfS1FLFxkxQuiaqRBj1vV5PmgHX_jA_c1ncL',
            production: '<insert production client id>'
          },

          payment: function() {
            var env = this.props.env;
            var client = this.props.client;

            return paypal.rest.payment.create(env, client, {
              transactions: [{
                amount: {
                  total: '1.00',
                  currency: 'USD'
                }
              }]
            });
          },

          commit: true, // Optional: show a 'Pay Now' button in the checkout flow

          onAuthorize: function(data, actions) {

            // Optional: display a confirmation page here

            return actions.payment.execute().then(function() {
              // Show a success page to the buyer
            });
          },
          style: {
            color: 'black',
            shape: 'rect'
          }
        };
      }]);
      
      app.directive('testDirective', [function () {
        return {
            restrict: 'E',
            template: '<paypal-button env="paypal.env"   style="paypal.style" client="paypal.client"  payment="paypal.payment"  commit="paypal.commit"  on-authorize="paypal.onAuthorize"></paypal-button>',
            scope: {
                paypal: '='
            },
            link: function (scope, element, attrs, controller) {
            }
        };
    }]);
    }());
