How to do mouse hover using Selenium WebDriver in Firefox 19?

问题

I have used selenium 2.31.

I have used Actions class for mouse movement. Using this I moved the mouse over a menu and its submenu appeared only for a fraction of second unlike with older version of firefox .

Beacuse of this issue I cannot select the sub menu using driver.findElement as it throws an exception "element cannot be scrolled into view".

Is there any solution for this?

回答1:

With the actions object you should first move the menu title, and then move to the popup menu item and click it. Don't forget to call actions.perform() at the end. Here's some sample Java code:

Actions actions = new Actions(driver);
WebElement menuHoverLink = driver.findElement(By.linkText("Menu heading"));
actions.moveToElement(menuHoverLink);

WebElement subLink = driver.findElement(By.cssSelector("#headerMenu .subLink"));
actions.moveToElement(subLink);
actions.click();
actions.perform();

Another way to go about this is to use Selenium's JavaScript Executor to force the style of the element to be displayed.

An Example of this would be along this lines in C#

//Use the Browser to change the display of the element to be shown
 (IJavaScriptExecutor)driver).ExecuteScript("document.getElementById('myId').stlye.display="block");

//navigate to your link that is now viewable 
driver.FindElement(By.Xpath('//LinkPath')).Click();

From there, you can find the XPath to your element and use selenium to click on the element. You can cascade this to find children of your main element as well

//(IJavaScriptExecutor)ffbrowser).ExecuteScript("document.getElementById('myId').children[1].children[1].style.display='block'");

Note that this is only possible if you have a hover element that changes the display style when hovered over.

Try this code... It's c sharp code...

//Webelement is the main menu Link
webElement = driver.FindElement(By.XPath("Your element xpath"));
Actions act = new Actions(driver);
        act.MoveToElement(webElement).Perform();//This opens menu list

        System.Threading.Thread.Sleep(5000);//This line will help you to hold menu 
 //This web element is the sub menu which is under main menu
        webElement = driver.FindElement(By.XPath("Sub menu path"));
        act.MoveToElement(webElement).Perform();//This opens menu list
        System.Threading.Thread.Sleep(5000);//Holds menu
    //This web element is the option you have to click
        webElement = driver.FindElement(By.XPath("Path"));
        webElement.Click();

This will be helpful if you are using Ruby.

1.First you need to find element by xpath or id.

2.Then use the method action.move_to().perform.

Here is the code:

    hover = WAIT.until{$driver.find_element(:xpath,"xpath")}
    driver.action.move_to(hover).perform

This answer helped solve my problem.

My challange was to find a link under a menu option. The link was not visible until I hovered over the Menu.

This crucial part for me was finding out that in addition to hovering over the menu, I next had to hover on the link in order to interact with it.

List<WebElement> list = driver.findElements(By.xpath("//a"));
        for (int i=0;i<list.size();i++){
        if(list.get(i).getText().equalsIgnoreCase("cacique intimates M"))
            {
    new Actions(driver).moveToElement(list.get(i)).click().build().perform();
    System.out.println("Clicked on Parent Category");
    new Actions(driver).moveToElement(list.get(i)).moveToElement(driver.findElement(By.linkText("SPECIALTY BRAS"))).click().build().perform();
        break;
    }                           
    }
