Question

如何从元素中选择elementS。例如，我有下一个元素div块，并希望从这个div块中选择所有类型等于radio的元素：

 private static readonly By divBlock =By.XPath("//*[@contains(@id, 'qst_8220_qst_8235')]");

 private static readonly By elementType = By.XPath(".//*[@type='radio']");

此代码对我不起作用：

foreach (var elem in WebDriver.FindElement(divBlock).FindElements(elementType))
        {
            elem.Click();
        }

错误：对象引用未设置为对象的实例。

Answer 1

尝试这种方式：

IWebDriver Driver = new (select some driver);

var divBlock = Driver.FindElement(By.Xpath("//*[@contains(@id, 'qst_8220_qst_8235')]"));

var elementType = Driver.FindElements(By.XPath(".//*[@type='radio']"));

foreach (var elem in elementType.Count)
{
elem.Click();
}

Answer 2

IWebElement有方法findelements。所以你可以尝试这种方式

private static readonly By divBlock =By.XPath("//*[@contains(@id, 'qst_8220_qst_8235')]");

private static readonly By elementType = By.XPath(".//*[@type='radio']");

IWebElement Block = Driver.FindElement(divBlock);

List<IWebElement> elementTypes = Block.FindElements(elementType);

Console.WriteLine(elementTypes.count);

foreach (var elem in elementTypes)
{
    elem.Click();
}
