摊销下拉元素存在问题

WebElement drpAmortization = driver.findElement（By.xpath（“// select [@ id ='Amortissement']”））;

我已经检查了页面的html代码，而下拉列表不是传统的选择下拉列表。它只是一个像按钮一样的按钮。所以方法如下，

  1. 单击向下箭头按钮：

    driver.findElement(By.xpath("//*[@id='form_calculateur_versements']/div[4]//b")).click();

    2. 现在可以看到选项。

    1. 从下拉列表中选择选项：

      driver.findElement(By.xpath("//*[@id='form_calculateur_versements']/div[4]//li[2]")).click();

      2. 我从上面代码的下拉列表中选择了第二个选项。

      类似的方法适用于页面中的所有下拉菜单。

      希望这会对你有所帮助。感谢。

Amortization下拉列表不是标准的选择控件，因此您使用的xpath将不起作用。此外，标准Webdriver API（如selectByVisibleText等）不能用于从此类下拉列表中选择值。但是，您可以编写自己的自定义通用方法来从中选择值，如下所示：

public static void selectText(String dropDownLabel, String value) {
  String showOptions = "//label[normalize-space(text())='" + dropDownLabel + "']/following::b[1]";

  driver.findElement(By.xpath(showOptions)).click();
  WebDriverWait wait = new WebDriverWait(driver, 10);
  String option = "//label[normalize-space(text())='" + dropDownLabel + "']/following::li[normalize-space(text())='"
          + value + "']";
  wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath(option))));

  driver.findElement(By.xpath(option)).click();
}

在上面的代码中，单击下拉列表后，Webdriver将等待下拉选项出现，然后单击所需的选项。如果您有进一步的疑问，请与我们联系。

以下是您的问题的答案：

关于解决方案的几句话：

  1. 诱导ExplicitWait没有ExpectedCondition会违反wait=new WebDriverWait(driver, 50);中出现的隐含目的，您可以考虑将其删除。
  2. xpath //div[@class='slider-handle min-slider-handle custom']不是唯一的。您可以考虑构建一个唯一的xpath。
  3. xpath //div[@class='slider-track-high']不是唯一的。您可以考虑构建一个唯一的xpath。
  4. 您已从Dimension导入了java.awt.Toolkit;班级，而您可能会考虑从Dimension
    5. 导入org.openqa.selenium.Dimension;班级
  5. 根据最佳编程惯例，您可以考虑腾出所有Thread.sleep();并通过ExplicitWait替换
  6. Amortization是Modal Dropdown，因此您可以考虑正确处理它。
  7. 您可以考虑将代码块中不必要的导入从org.junit.Assert;删除，因为它从未实现过。

  8. 以下是您自己的代码，其中包含一些最小的调整，在控制台的程序末尾打印Value selected from Dropdown is : 20 years。
