对于 selenium，asp.net RadioButton 始终显示为 false

Question

我有一个如下的用户界面，我正在尝试自动化它。

我的html内容如下：

<div class="medium-5 columns tableheading-td">
  <ul id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers" class="assessment-main-layout tabled-list" onchange="ChangeTextColorForSelectedRadio(this);">
    <li>
      <input id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0" type="radio" name="ctl00$ctl00$ContentPlaceHolder1$QuetionListPlaceHolder$BigFiftyPersonalityQuestion1$BigFiftyPersonalityQuestionItem1221754$rdbListAnswers"
        value="0">
      <label for="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0"> </label>
    </li>
    <li>
      <input id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_1" type="radio" name="ctl00$ctl00$ContentPlaceHolder1$QuetionListPlaceHolder$BigFiftyPersonalityQuestion1$BigFiftyPersonalityQuestionItem1221754$rdbListAnswers"
        value="1">
      <label for="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_1"> </label>
    </li>
    <li>
      <input id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_2" type="radio" name="ctl00$ctl00$ContentPlaceHolder1$QuetionListPlaceHolder$BigFiftyPersonalityQuestion1$BigFiftyPersonalityQuestionItem1221754$rdbListAnswers"
        value="2" style="">
      <label for="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_2"> </label>
    </li>
    <li>
      <input id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_3" type="radio" name="ctl00$ctl00$ContentPlaceHolder1$QuetionListPlaceHolder$BigFiftyPersonalityQuestion1$BigFiftyPersonalityQuestionItem1221754$rdbListAnswers"
        value="3">
      <label for="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_3"> </label>
    </li>
    <li>
      <input id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_4" type="radio" name="ctl00$ctl00$ContentPlaceHolder1$QuetionListPlaceHolder$BigFiftyPersonalityQuestion1$BigFiftyPersonalityQuestionItem1221754$rdbListAnswers"
        value="4">
      <label for="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_4"> </label>
    </li>
  </ul>
</div>

我正在尝试按如下方式单击我的单选按钮：

IWebElement webElement= CommonProperties.driver.FindElement(By.Id("ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_2"));
webElement.ClickElement();

但它说元素显示为假。 他这是什么原因，我该如何解决这个问题？

我已经尝试过使用 xpath：

 IWebElement webElement= CommonProperties.driver.FindElement(By.XPath("//*[@id='ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0']"));

（有两个用于单选按钮和标签的 xpath。即使遇到同样的问题。

//*[@id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0"]

//*[@id="ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers"]/li[1]/label

我使用过的 Nuget 如下：

Answer 1

exception details : element not visible (Session info: chrome=72.0.3626.109) (Driver info: chromedriver=2.37.544315 (730aa6a5fdba159ac9f4c1e8cbc59bf1b5ce12b7),platform=Windows NT 10.0.10586 x86_64)

这表明您使用的是旧版本的chromedriver=2.37.544315，它与chrome version 72 不兼容。您需要升级您的 chrome 驱动程序才能兼容。我相信这会解决您的问题。

请看下面link。

Answer 2

你可以尝试使用 visibilityOfElementLocated 这个来等待元素点击之前

WebDriverWait wait = new WebDriverWait(driver, 10);
var clickableElement = wait.Until(ExpectedConditions.visibilityOfElementLocated(By.XPath("//*[@id='ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0']")));

Answer 3

我能够找出我的问题。根据样式类单选按钮被禁用。因此它总是显示为假。我可以通过单击相关标签文本来单击单选按钮。我是这样做的

 // get lable for selected radio button
IWebElement radioButtonSelectedLabel = CommonProperties.driver.FindElement(By.CssSelector("label[for='ContentPlaceHolder1_QuetionListPlaceHolder_BigFiftyPersonalityQuestion1_BigFiftyPersonalityQuestionItem1221754_rdbListAnswers_0']"));
// click on the label
radioButtonSelectedLabel.ClickElement();
