提问by Krishna Yadav
I want to click submenu item using selenium webdriver which is invisible bydefault. It becomes visible on mousehover . I tried with some code and it is giving error as shown below
我想使用默认情况下不可见的 selenium webdriver 单击子菜单项。它在 mousehover 上变得可见。我尝试了一些代码，它给出了如下所示的错误
Caused by: org.openqa.selenium.remote.ErrorHandler$UnknownServerException: Element is not currently visible and so may not be interacted with.
Caused by: org.openqa.selenium.remote.ErrorHandler$UnknownServerException: Element is not currently visible and so may not be interacted with.
Here the code:
这里的代码：
Actions actions = new Actions(driver);
WebElement menuHoverLink = driver.findElement(By.linkText("RENT"));
//WebElement menuHoverLink = driver.findElement(By.className("current"));
actions.moveToElement(menuHoverLink);
WebElement subLink = driver.findElement(By.cssSelector("a[href='nemc.com/rentals/easy-rent']"));
actions.moveToElement(subLink);
actions.click();
actions.perform();

Use the Actionsclass to do a mousehover on your menu item and then a click on the submenu option. You can refer to Actions class to get an overview of the methods available and a good help hereto understand how to use these interactions.
使用Actions类将鼠标悬停在菜单项上，然后单击子菜单选项。您可以参考 Actions 类来获得可用方法的概述，并在此处提供很好的帮助，以了解如何使用这些交互。
Actions actions = new Actions(driver); WebElement menuHoverLink = driver.findElement(By.linkText("RENT"));
actions.moveToElement(menuHoverLink).perform();
driver.findElement(By.cssSelector("a[href='nemc.com/rentals/easy-rent']")).click();
I am hoping your locatros are correct..you might want to use a[contains(@href,'nemc.com/rentals')'
我希望你的定位是正确的..你可能想使用 [contains(@href,'nemc.com/rentals')'

Try using the below code. It should work.Try adding perform() to your moveToElement statement as shown below.
尝试使用以下代码。它应该可以工作。尝试将 perform() 添加到您的 moveToElement 语句中，如下所示。
Actions actions = new Actions(driver);
WebElement menuHoverLink = driver.findElement(By.linkText("RENT"));
actions.moveToElement(menuHoverLink).perform();
WebElement subLink = driver.findElement(By.cssSelector("a[href='nemc.com/rentals/easy-rent']"));
sublink.click();

In some applications the Actioninteractions may not work. Personally i faced the problem and then i used the below solution. I took this solution from selenium issue tracker page.
在某些应用程序中，Action交互可能不起作用。我个人遇到了这个问题，然后我使用了以下解决方案。我从 selenium 问题跟踪器页面获取了这个解决方案。
WebElement targetElement = driver.findElement(By.id("locator"));
JavascriptExecutor js = (JavascriptExecutor) driver;
String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
js.executeScript(mouseOverScript, targetElement);
driver.findElement(By.id("Click locator")).click;

I stumbled across a similar issue recently, with phantomJSand ghostdriver. In my case, the problem was the window size - the HTML element was outside the visible area and my mouse movements were having no effect (default size is 400x300, which is rather small).
我最近偶然发现了一个类似的问题，phantomJS和ghostdriver。就我而言，问题在于窗口大小 - HTML 元素在可见区域之外，我的鼠标移动没有效果（默认大小为 400x300，相当小）。
You can check the window size with
您可以检查窗口大小
driver.manage().window().getSize()
And you can change it with
你可以改变它
driver.manage().window().setSize(new Dimension(width, height));
