如何在下拉列表中获取选定的值

HTML代码：

<select  name="appealStatusId" class="form-control input-sm">
  <option value="1">
      Pending
  </option>

  <option value="2">
      Overall Appeal Approved
  </option>

  <option value="3" selected="selected">
      Overall Appeal Not Approved
  </option>

Answer 1

您可以 select 根据下拉选项中的值、文本或 ID 来选择元素。

通过使用文本：

IWebDriver driver = new ChromeDriver();

driver.Navigate().GoToUrl("your_URL");

driver.Manage().Window.Maximize();

IWebElement element_name = driver.FindElement(By.Name("appealStatusId"));

SelectElement statusId = new SelectElement(element_name);

// To print all available options    
Console.WriteLine(statusId.Options);

// To iterate over the dropdown options and select the one which matches with the text you want to select
foreach(IWebElement  element in statusId.Options)
     {
          if(element.Text == "Overall Appeal Not Approved")
          {
               element.Click();
          }
     }

或使用 SelectByValue:

IWebDriver driver = new ChromeDriver();

driver.Navigate().GoToUrl("your_URL");

driver.Manage().Window.Maximize();

IWebElement element_name = driver.FindElement(By.Name("appealStatusId"));

SelectElement statusId = new SelectElement(element_name);

statusId.SelectByValue("3");

Answer 2

要在下拉列表中获得所选值，您必须引入 WebDriverWait for the element_to_be_clickable() and you can use either of the following :

• 使用 CssSelector:

  SelectElement status = new SelectElement(driver.FindElement(By.CssSelector("select[name='appealStatusId']")));
  IWebElement selected = status.SelectedOption;
  Console.Write(selected.Text);
  

• 使用 XPath:

  SelectElement status = new SelectElement(driver.FindElement(By.XPath("//select[@name='appealStatusId']")));
  IWebElement selected = status.SelectedOption;
  Console.Write(selected.Text);
  

• 使用名称:

  SelectElement status = new SelectElement(driver.FindElement(By.Name("appealStatusId")));
  IWebElement selected = status.SelectedOption;
  Console.Write(selected.Text);
