Question

我正在尝试创建一个自动将我登录到网页的应用。页面不是我的，所以我看不到它背后的代码。 http://pcc.magister.net（第一个通知屏幕后的页面）

现在我设法插入了用户名和密码，但我似乎无法触发点击页面上的按钮。我得到了这个：

var functionString = string.Format(@"document.getElementsByClassName('primary-btn ripple')[0].click();");
await Display.InvokeScriptAsync("eval", new string[] { functionString });

但我得到的只是错误。＆＃39; System.Exception的＆＃39;在System.Private.CoreLib.ni.dll和0x80020101事件中，这是一般的javascript错误。

DOM资源管理器中的按钮如下所示：

<mg-button is-loading="$ctrl.isLoading" caption="doorgaan">
<button class="primary-button ripple" type="submit" ng-class="{'active': $ctrl.isLoading}">
</button></mg-button>

任何比我更聪明的人看到我在这里做错了什么？
