• • Java中的代码**

public class SeleniumService {

    private int dirationInSeconds = 120;

    private WebElement findChildByXpath(WebDriver driver, WebElement parent, String xpath) throws WebElementNotFoundException {
        loggingService.timeMark("findElementByXpath", "begin. Xpath: " + xpath);

        WebElement result = null;

        try {
            result = new WebDriverWait(driver, Duration.ofSeconds(dirationInSeconds))
                    .until(ExpectedConditions.elementToBeClickable(By.xpath(xpath)));
        } catch (TimeoutException e) {
            throw new WebElementNotFoundException();
        } catch (Exception e) {
            // Mustn't be here.
            System.out.println(e.getMessage());
            System.out.println("QUIT!");
            System.exit(0);
        }

        return result;
    }
}

上面的代码不起作用，因为它是关于"WebDriverWait（driver）"的。它与"driver"得到的页面相关，而不是父元素。
此代码适用于：

WebElement frequencyElement = parent.findElement(By.xpath("//span[@class='dc-Text__text dc-verticalAlign dc-verticalAlign_text_12-16 dc-verticalAlign_addon_12 dc-typography dc-typography_size_12-16 dc-typography_role_main dc-typography_color_gray dc-typography_bold dc-Text dc-Text_textAlign_left']"));

但是这段代码没有配备WebDriverWait。
你能帮我把这两个代码组合起来，这样子元素就应该被找到，WebDriverWait就被应用了。
