我遇到的问题是当代码第一次运行时optionalClick(By.cssSelector(CONSTANTs.OK_CONTINUE_AS))此代码在元素存在时运行。但是当代码第二次运行时，optionalClick(By.cssSelector(CONSTANTs.OK_CONTINUE_AS))此代码不应该运行，因为该元素将不存在。

现在我希望其他人工作，但我正在冻结。我认为我的问题是在屏幕之间切换，如果我是对的，但我在这里完全混淆。

对于optionalClick方法，请使用explicit wait。如果在10秒内找到元素（根据代码），则单击元素。否则会引发超时异常并在catch块中处理它。

try{
   (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(by)));
   driver.findElement(by).click();
   }
catch(TimeoutException te){
}

如果下一个元素不存在，则打破for循环
