Java Selenium-如何在基于AngularJS的页面中单击没有ID或ng-class的按钮 [英] Java Selenium - How to Click a Button that has no ID or ng-class in AngularJS based page

问题描述

我使用的以下代码没有单击按钮并显示错误消息.

The following code I've used is not clicking the button and showing the error message.

WebElement clickNextButton = webDriver.findElement(By.cssSelector("button[ng-class='btn-success']"));
clickNextButton.click();

错误消息显示没有这样的元素:无法找到元素.{"method":"css选择器"，"selector":"button [ng-class ='btn-success']"}

Error message shows "no such element: Unable to locate element. {"method":"css selector","selector":"button[ng-class='btn-success']"}

我还尝试了以下代码段，但均未成功:

I've also tried the following code segments without success:

  WebElement clickNext1 = webDriver.findElement(By.cssSelector("button[ng-class='pccCTRL.pow.Page1InputsValid() ? 'btn-success' : 'btn-default'']"));
  clickNext1.click();

 webDriver.findElement(By.partialLinkText("Next")).click();

  webDriver.findElement(By.cssSelector("button[type='button']")).click();   

以下是屏幕截图，显示了我要尝试操作的按钮的html代码段
