Java 从下拉列表中选择元素

我想在Joomla中测试一个应用程序。 我有一个包含以下代码的下拉列表：

<div class="control-group">
    <div class="control-label">
        <label id="jform_category-lbl" for="jform_category" class="required">
            Categoria<span class="star">&#160;*</span>
        </label>
    </div>
    <div class="controls">
        <select id="jform_category" name="jform[category]" class="required" required aria-required="true">
            <option value="9">stanza singola</option>
            <option value="10">stanza doppia</option>
            <option value="11">posto letto</option>
        </select>
    </div>
</div>

我正在使用Java来测试这个站点。 我如何从下拉列表中选择节doppia选项？

您考虑过使用类吗

我已经在你提到的网站上试过了，它对我很有效。 实际上，您需要使用自定义xpath从下拉列表中选择值并将其存储在列表中。然后单击所需的值

有时选择不起作用，您可以使用此解决方法在下拉列表中选择值

下面是同样的工作代码

import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.support.ui.WebDriverWait;

public class SelectDropdown {

    public static void main(String[] args) {

        WebDriver driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
        driver.manage().window().maximize();
        driver.get("http://bachecalloggi.listedisinistra.org/index.php/annunci");
        driver.findElement(By.xpath("//button[contains(text(),'Ricerca Avanzata')]")).click();
        select1(driver);
    }

        public static void select1(WebDriver driver) {
                  //Clicking on the Element to open the dropdown. 
                  WebElement clickme = driver.findElement(By.xpath("//*[@id='filter_energy_class_chzn']/a/span"));
                  clickme.click();
                  //Sometime need to wait, as it take some time to load the values in dropdown.
                  //Thread.sleep(3000);

                  //Picking all the value from Dropdown. Use Custom Xpath for this.
                  List<WebElement> options = driver.findElements(By.xpath("//*[@id='filter_energy_class_chzn']//*[@class='chzn-results']/li"));

                  for (int i=0; i<options.size(); i++){
                   if (options.get(i).getText().equalsIgnoreCase("B")){
                    options.get(i).click();
                   }
                  }         

        }
}

创建Select对象会有帮助，这在第一个答案中提到。我尝试了，但没有成功：我在公共页面上遇到了相同的问题：这是代码：`public void testFilterAds抛出异常{driver.findElementBy.xpath//button[containstext，'Ricerca Avanzata'].click；WebElement elemnet=driver.findElementBy.idfilter\u energy\u class；Select=new Selectelemnet；//按值Select.selectByValueb；//按索引Select.selectByIndex2；//按文本Select.selectByVisibleTextB；Thread.sleep500000；}`未选择任何内容：您使用的代码与我使用的代码不同。您可以在第页的filter_energy_class下拉列表中发布一个completa class以选择B吗？请
