click command in selenium webdriver does not work

问题:

I have just recently done an export of my selenium IDE code to selenium web driver. I have found that a lot of the commands that worked in IDE either fail to work or selenium web driver claims to not support at all. So far I've been tackling these issues one at a time which is less than ideal...

Currently I'm working on finding out why clicking on a button does not work with web driver while it had previously worked in selenium IDE. My browser is FF 13 and my OS is Ubuntu.

Code Snippet

WebElement loginButton = driver.findElement(By.name("submit"));
loginButton.click();

I had previously tried

driver.findElement(By.name("submit")).click();

however the above line failed as well. The element is getting selected, however it does not log us in as I would like. I found other pages with similar problems, but their problem seemed to be with Internet Explorer not Firefox. I don't even want to think about the problems IE will give me down the road.

thanks,

P.S. A tip on a better way to migrate from selenium IDE to Selenium Webdriver without losing all the tests I've written could solve this issue as well.

回答1:

If you know for sure that the element is present, you could try this to simulate the click - if .Click() isn't working

driver.findElement(By.name("submit")).sendKeys(Keys.RETURN);

or

driver.findElement(By.name("submit")).sendKeys(Keys.ENTER);

A major thing to watch out for is whether a button is Enabled or not. You can still click them and nothing will fall over and the element is there but it is not ready to be clicked on so just doesnt do anything.

I've been using webdriver and its taken me most of the day to figure this out!

The following method seems to work reliably (in my environment for one button!)

    private void TryClick(By selector)
    {
        var wait = WaitUpTo(TimeSpan.FromSeconds(10));
        var element = wait.Until(ExpectedConditions.ElementIsVisible((selector)));

        //really important bit!
        WaitUpTo(TimeSpan.FromSeconds(5))
            .Until(d => element.Enabled);

        element.Click();
    }

you use it something like

TryClick(By.XPath("//button[contains(.//*,'Some Text')]"));

Thanks for all the answers everyone! I have found a solution, turns out I didn't provide enough code in my question.

The problem was NOT with the click() function after all, but instead related to cas authentication used with my project. In Selenium IDE my login test executed a "open" command to the following location,

/cas/login?service=https%1F%8FAPPNAME%2FMOREURL%2Fj_spring_cas_security

That worked. I exported the test to Selenium webdriver which naturally preserved that location. The command in Selenium Webdriver was,

driver.get(baseUrl + "/cas/login?service=https%1A%2F%8FAPPNAME%2FMOREURL%2Fj_spring_cas_security");

For reasons I have yet to understand the above failed. When I changed it to,

driver.get(baseUrl + "MOREURL/");

The click command suddenly started to work... I will edit this answer if I can figure out why exactly this is.

Note: I obscured the URLs used above to protect my company's product.

Please refer here https://code.google.com/p/selenium/issues/detail?id=6756 In crux

Please open the system display settings and ensure that font size is set to 100% It worked surprisingly

There's nothing wrong with either version of your code. Whatever is causing this, that's not it.

Have you triple checked your locator? Your element definitely has name=submit not id=submit?

I was using firefox and some reason, it was not taking the click command though from past 2months it was working. My feeling was to make use of sendKeys and this page solved the problem. Now I am using sendKeys(Keys.Enter)
