如何使用Selenium WebDriver悬停并单击不可见元素? [英] How to Hover over and click on an invisible element using selenium webdriver?

问题描述

我的HTML页面上有一个不可见的元素，当鼠标悬停在该元素上时，该元素将变为可见.

There is an invisible element on my HTML page which becomes visible when a mouse hover is done on the element. What I Have to do is

1. 将鼠标悬停在元素上
2. 单击元素(它将显示4个选项)
3. 单击选项之一

我正在将Java API用于Selenium Web驱动程序，以下是我一直在尝试的

I am using Java API for selenium web driver and following is what I have been trying

Actions builder = new Actions(driver);
builder.moveToElement(MainMenuBTN).click().build().perform();

subMenuBTN.click();

1. MainMenuBTN =鼠标悬停时可见的元素
2. subMenuBTN =从菜单选项中选择的元素 显示的

1. MainMenuBTN = element that becomes visible when you hover the mouse over it
2. subMenuBTN = element that is being chosen out of the menu options that are displayed

正在发生的是，MainMenuBTN上的click()正在生成ElementNotVisible异常. 为了避免这种情况，我尝试了以下操作，但是没有用.

What is happening is, the click() on MainMenuBTN is generating ElementNotVisible exception. I tried following to avoid this, but did not work.

Actions builder = new Actions(driver);
builder.moveToElement(mainMenuBTN).build().perform();
builder.click();

subMenuBTN.click();

A注意:mainMenuBTN和subMenuBTN是由以下元素生成的WebElements

A Note : mainMenuBTN and subMenuBTN are WebElements generated by

driver.findElement(By.xpath("xpath_string"))

我错过了什么吗?帮助赞赏！
