Selenium：无法单击在使用find元素时找到的按钮，这在JS和Simple formatted way[duplicate]中都失败

Question

我试图单击一个按钮，尝试使用其id、CSS和XPath，该按钮可通过findElement获得，但在单击时不执行操作。这是示例代码，也遵循异常。

  WebElement PageSpeedTestbutton1 = driver.findElement(By.cssSelector("#files")); 
            System.out.println("Found");    
            WebElement PageSpeedTestbutton2 = driver.findElement(By.xpath("//input[@id='files']"));
            System.out.println("Found");    
            PageSpeedTestbutton1.click();
            PageSpeedTestbutton2.click();
            System.out.println("Clicked Checker");



Results:

Answer 1

以下错误表明您的元素可用，但不可单击。

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: Element is not clickable at point 

尝试下面的代码，它应该可以工作。

WebElement PageSpeedTestbutton1 = driver.findElement(By.cssSelector("#files")); 

Actions action = new Actions(driver);
action.moveToElement(PageSpeedTestbutton1).click().build().perform();

或

WebElement PageSpeedTestbutton1 = driver.findElement(By.cssSelector("#files")); 

JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", PageSpeedTestbutton1);

编辑

List<WebElement> PageSpeedTestbuttons = driver.findElements(By.cssSelector("#files"));
        if (PageSpeedTestbuttons.size()>0)
        {
            WebElement PageSpeedTestbutton1 =PageSpeedTestbuttons.get(0); 
            Actions action = new Actions(driver);
            action.moveToElement(PageSpeedTestbutton1).click().build().perform();
        }
        else
        {
            System.out.println("Element is not available");
        }
