我使用的以下代码未单击按钮并显示错误
消息。

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

Error message shows “no such element: Unable to locate element.

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

1. WebElement clickNext1 = webDriver.findElement(By.cssSelector(“button[ng-class=’pccCTRL.pow.Page1InputsValid() ? ‘btn-success’ : ‘btn-default’‘]”));
   clickNext1.click();

2. webDriver.findElement(By.partialLinkText(“Next”)).click();

3. webDriver.findElement(By.cssSelector(“button[type=’button’]”)).click();

Here is the screenshot showing the html code segment of the button I’m trying
to

Hoping to get feedback. Thank you.
