Selenium WebDriver SubMenu点击不起作用

Question

I am not able to Click on SubMenu item using selenium webdriver using c#. I am using IE9 and FireFox 13. I have tried Action Builder but it does not work. It gives an error saying element cannot be clicked.

    WebDriverWait Wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(5));
    IWebElement menu = Wait.Until((d) => webDriver.FindElement(By.Id("id1")));
    IWebElement menuOption = Wait.Until((d)=>webDriver.FindElement(By.Id("ID2")));
            Actions builder = new Actions(webDriver);
            builder.MoveToElement(menu).Build().Perform();
            Thread.Sleep(5);
            //then click when menu option is visible
            menuOption.Click();

I have used even javascript : js.ExecuteScript("return $(\\"a:contains('ID1')\\").mouseover();"); // Mouse hove to main menu
webDriver.FindElement(By.Id("ID2")).Click();

Please give some solution to click on hidden elements

Answer 1

You could use Expected Conditions to wait for element being clickable after hovering above it ( Thread.sleep() is almost always the bad choice. And 5 ms won't be enough.).

The docs for this class ( ExpectedConditions in OpenQA.Selenium.Support.UI namespace) are broken as I can see them now, but if you can follow the Java code in the link above, here are the Expected conditions for Java - it's really almost the same in C#, too.

Instead of using the statement Thread.sleep() . You can try to click on the element after making sure that it is displayed.

After you get the WebElement you want to click on , check if it is displayed by using the isDisplayed() method within the ExpectedContition statement about which @Slanec is talking about in the above post.

By this you can make sure you will click on the element only after Wait.Until() returns true . ie the menuOption is displayed.

I'm writing the code in java as I do not know C#. But I guess you can figure out what I'm trying to say -

    new WebDriverWait(driver, 60).until(new ExpectedCondition<Boolean>() {

        public Boolean apply(WebDriver driver ) {


            return driver.findElement(By.Id("ID2")).isDisplayed();
        }
    });

I hope that this helps you.
