java - ChromeDriver 无法访问选择

Question

我正在尝试强制 ChromeDriver 从选择框中选择一个项目。然而它失败了

    Options = select.getOptions(); 

奇怪的是，在下面的代码中，getText();方法打印出选择中的所有项目:

  productChoooser.getText() = ...
  BASE 2013
  BASE 2014

但我仍然遇到异常...尝试单击选择框中的项目的代码:

    List<WebElement> Options;
    WebElement productChoooser = driver.findElement(By.id("mainForm:aucPanelId:1:product"));
    System.out.println("productChoooser.getText() = " + productChoooser.getText());
    Select select = new Select(productChoooser);
    Options = select.getOptions();
    String product = "BASE 2013";
    for (WebElement option:Options){
        System.out.println("option.getText() = " + option.getText()); 
       if(option.getText().equals(product)){
           option.click();
       }
    }

有人知道如何避免吗？我尝试将 Chrome 和 chromedriver.exe 更新到最新版本，但没有成功...

        WebElement select = webDriver.findElement(selector);
        List<WebElement> optionList = select.findElements(By.tagName("option"));
        for (WebElement option : optionList) {
            if (option.getText().trim().equalsIgnoreCase("your value")) {
                option.click();
                break;
            }
        }
