Selenium:该元素无法滚动到 View 中

Question

您好，我遇到了下面提到的错误。
我无法点击屏幕截图中提到的买方按钮。
我也试过等待、 sleep 功能。
但无法超越这一点。任何人都可以帮助我。

任何人都可以帮我解决这个问题:
Inspect Element code is .

代码是:

driver.findElement(By.name("login")).click();  //Click on login button
    System.out.println("hello world-----4");

    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {

        e.printStackTrace();
    }   
    System.out.println("hello world-----5");
    WebElement element = driver.findElement(By.xpath("//*
[@id=\"modeuser\"]/div/ul/li[3]"));
    ((JavascriptExecutor) 
driver).executeScript("arguments[0].scrollIntoView(true);", element);
    element.click();                                                                                    
//Click on usertype



Error:

HTML is :

<div class="right hide-on-med-and-down head_right_mar" id="modeuser">

                        </li>
                    </ul>
                </div>


            </div>

Answer 1

首先，验证元素在您的框架中 .

如果不是，您将需要切换到正确的框架才能单击元素:

driver.switchTo().frame(driver.findElement(By.name("iframeWithElement")));

此外，您可以执行许多步骤来提高单击不同 UI 元素时的稳定性:

明确 等待它的存在在 DOM 中

滚动 进入元素 View

检查是否 可点击

对稳定性有帮助吗？

WebDriverWait wait = new WebDriverWait(driver, 3);
JavascriptExecutor js = ((JavascriptExecutor) driver);

//presence in DOM
wait.until(ExpectedConditions.presenceOfElement(By.id("ID")));

//scrolling
WebElement element = driver.findElement(By.id("ID")));  
js.executeScript("arguments[0].scrollIntoView(true);", element);

//clickable
wait.until(ExpectedConditions.elementToBeClickable(By.id("ID")));

例如，如果我正在处理 site ，我将使用:

Wait.until(ExpectedConditions.presenceOfElement(By.class("article-feed-title")));
