无法读取未定义的属性 'configure'

Question

我收到错误：

core.js:5882 ERROR TypeError: Cannot read property 'configure' of undefined

当我在 Angular 中为万事达卡实施 Hosted Session Integration 时 2. 这是我的代码：

付款-detail.component.ts

<div>Security Code:<input type="text" id="security-code" class="input-field" value="1234" readonly></div>
<div><button id="payButton" onclick="pay();">Pay Now</button></div>

如果我从 $.PaymentSession.configure 中删除 $.，我将无法找到 PaymentSession。

我按照 Maxine Lafarie 的建议使用了这段代码：

$.getScript( "your-script", function( data, textStatus, jqxhr ) {
  console.log( data ); // Data returned
  console.log( textStatus ); // Success
  console.log( jqxhr.status ); // 200
  console.log( "Load was performed." );
});

这是结果：

undefined payment-detail.component.ts:31 success payment-detail.component.ts:32 200 payment-detail.component.ts:33 Load was performed.

将 url 粘贴到浏览器我得到一个脚本：

Answer 1

您是否绑定记录了 $.getScript 的响应？

你可以这样做：

$.getScript( "your-script", function( data, textStatus, jqxhr ) {
  console.log( data ); // Data returned
  console.log( textStatus ); // Success
  console.log( jqxhr.status ); // 200
  console.log( "Load was performed." );
});

无论如何，我不知道您是在整个应用程序中使用 jQuery 还是只是为了 getScript 方法的“好处”，但我建议您避免混合使用Angular 和 jQ，因为 Angular 绝对可以做 jQuery 能做的所有事情。

如果您想以 Angular 方式加载第 3 方脚本，您可以 .

所以检查是否：

jQuery 被很好地导入 and/or 在你调用它时加载到你的组件中
调用 $.getScript 方法后，您有一些成功日志
导入第 3 方脚本的 Angular 方法有效（可能更好）

编辑：

自从您导入脚本后，您就可以这样调用全局属性： $.PaymentSession.configure 但我认为你必须这样称呼它：PaymentSession.configure
