我尝试过的简单代码：

    driver.findElement(By.xpath("//input[@name='txtAccountName']")).sendKeys("CRSsolutions_test_" + today + "_tanksafe");

网页： http://ussbyintv8057.acetst.com/Enterprise_CRS/Login/login1.aspx

进入此页面的步骤：

  1. 使用用户名adyami和密码1234登录 2.点击顶部的新政策链接
  2. 从pf产品列表中，选择“坦克安全”
  3. 单击下一步
  4. 这是我们需要提供帐户名称和状态的页面

很可能您只需要等待元素出现即可。使用explicit wait代替findElement：

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement txtAccountName = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@name='txtAccountName']")));
txtAccountName.sendKeys("CRSsolutions_test_" + today + "_tanksafe");

此模式最多允许等待10秒，但如果满足条件，则返回速度更快。条件elementToBeClickable确保该字段是可单击的，这是输入值的前提。

查看U是否未通过使用wait进行定位，那么您需要使用绝对xpath来定位该元素。或者您也可以使用CSS选择器。

有时，对于有角度的网页，正常的xpath无法定位元素。如果它是有角度的，那么我建议使用量角器工具来自动进行硒

否则，如果相对xpath找不到您的元素，则绝对xpath将起作用。
