Question

我想使用selenium web驱动程序选择一个单选按钮。我的代码是

<div class="radio-switch-group" aria-label="RequestForCheckBox" role="menu">
<label>
    <input type="radio" name="request_for" value="self" ng-model="data.form.requestFor" class="ng-pristine ng-untouched ng-valid">
    <span class="radio-label" translate=""><span class="ng-scope">Self</span></span>
</label>
<label>
    <input type="radio" name="request_for" value="other" data-ng-click="$scope.getDataHandler()" ng-model="data.form.requestFor" class="ng-pristine ng-untouched ng-valid">
    <span class="radio-label" translate=""><span class="ng-scope">Others</span></span>
</label>
</div>

我尝试使用下面显示的代码找到元素

WebElement other = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"make-request-form\"]/div/section/div[2]/div/form/div[1]/div/div/div/label[2]/input")));
other.click();

但低于

 Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: //*[@id="make-request-form"]/div/section/div[2]/div/form/div[1]/div/div/div/label[2]/input (tried for 20 second(s) with 500 milliseconds interval)

有人可以帮我解决这个问题吗。

Answer 1

根据抛出的异常，您正在等待超时运行。

在默认超时20秒或您使用的xPath错误后，您的对象不存在。您可以尝试使用以下xPath选择第二个标签：(//input[@name="request_for"])[2]

Tipp：为了快速测试，将HTML代码传递到xPath生成器（例如：https://www.freeformatter.com/xpath-tester.html）并测试xPath表达式，而无需重新运行Selenium。

Answer 2

根据 HTML ，您已共享并且您的代码试验将继续进行，因为您将单击其中一个单选按钮而不是 ExpectedConditions visibilityOfElementLocated()您需要使用 elementToBeClickable() ，如下所示：

要点击与文字自我关联的单选按钮，您可以使用以下代码行：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-pristine ng-untouched ng-valid' and @value='self']"))).click();

要点击与文字其他关联的单选按钮，您可以使用以下代码行：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-pristine ng-untouched ng-valid' and @value='other']"))).click();

Answer 3

尝试使用visibilityOfElementLocated()代替{{1}}

无法使用selenium java选择单选按钮
