问题描述

我有一种情况,我必须将鼠标悬停在菜单链接上,然后单击下拉子菜单.我正在使用的代码如下:

I have a scenario where I have to hover over a menu link and click on the drop down sub menus. The code that I'm using is below:

public void changeLanguageTest() throws InterruptedException
    {
        WebElement LanguageMenu = driver.findElement(By.cssSelector(".change-language>button"));
        action.moveToElement(LanguageMenu);
        WebElement mongolianLang = driver.findElement(By.cssSelector(".change-language>ol>li:nth-child(3)>a"));
        action.moveToElement(mongolianLang).click().build().perform();
        Thread.sleep(3000L);
    }

但是当我运行这段代码时,它失败并显示一条错误消息:-

But when I run this code, It fails with an error message :-

我也尝试了下面提到的代码,但是没有成功,并且发生了相同的错误.

I tried below mentioned code too but no success and same error occurred.

BaseClass.action.moveToElement(LanguageMenu).moveToElement(mongolianLang).click().build().perform();

我正在使用webdriver v2.53并在FF v47.0.1上运行它.

I'm using webdriver v2.53 and running it on FF v47.0.1.

推荐答案

作为在此处记录的错误 geckodriver尚未实现actions.我们将执行的操作是现在在 W3C WebDriver standard 中定义的那些,而不是Selenium的那些

As a bug logged here geckodriver does not yet implement actions. The actions we will implement are those being defined right now in the W3C WebDriver standard and not those of Selenium.

硒已经表示将提供 Selenium-to-W3C-WebDriver 填充程序采取行动,但这可能需要一些时间才能实施. geckodriver/Marionette中的实施尚未开始.

Selenium has said they will provide a Selenium-to-W3C-WebDriver shim for actions, but this may take some time to produce after we have made our implementation. Implementation in geckodriver/Marionette has not yet started.

geckodriver的v0.12.0中提到的 ,为 new actions API 实施了路由,但在木偶中尚未完全实现

As mentioned here from v0.12.0 of geckodriver, Implemented routing for new actions API, but it too is not yet fully implemented in Marionette

您应该升级 geckodriver .

You should upgrade your geckodriver.
