java - 无法使用 selenium java 选择单选按钮

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>

我尝试使用下面所示的代码来定位元素

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();

但是低于

 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，您正在等待超时中运行。

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

提示:为了进行快速测试，请将 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。
