Element.Click not executed when using PhantomJS se

问题:

I am using our existing tool that works perfectly using the Firefox and Chrome implementations of the Selenium IWebdriver.

I am now doing some experimentation using the PhantomJS implementation. So far so good. However, as soon as I want to click a button it does nothing.

I can retrieve the element, however, looking closer at its properties the 'Selected' property states the following:

    Error Message => 'Element is not selectable' caused by Request => {"headers":{"Accept":"application/json, image/png","Connection":"Close","Host":"localhost:37704"},"httpVersion":"1.1","method":"GET","url":"/selected","urlParsed":{"anchor":"","query":"","file":"selected","directory":"/","path":"/selected","relative":"/selected","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/selected","queryKey":{},"chunks":["selected"]},"urlOriginal":"/session/fcaf88a0-40b4-11e3-960d-bdce3224aacf/element/%3Awdc%3A1383063211142/selected"}

I would gather this is the cause that my click is not executed, however, I cannot make heads or tails from this error message. using Google did not help either.

Any help would be much appreciated.

Thanks in advance.

We had a lot of similar issues with PhantomJS.

So, couple of steps to figure out what the root cause to it

1. Set you screen size (as suggested in comments; PhantomJS uses 400x300 by default):

   driver.Manage().Window.Size = new Size(1920, 1080); //Size is type in System.Drawing"
   

2. Use to verify that your element is actually visible:

   new WebDriverWait(driver,
   TimeSpan.FromSeconds(timeOut)).Until(ExpectedConditions.ElementExists((By.Id(login))));
   

3. Click on the element with Javascript

   IJavaScriptExecutor js = _driver as IJavaScriptExecutor;
   js.ExecuteScript("arguments[0].click();", buttonToClick); //buttonToClick is IWebElement
   

For Java it would be as follows:

1. Screen size

   driver.manage().window().setSize(new Dimension(width, height));
   

2. Verifying element is visible

   WebDriverWait wait = new WebDriverWait(webDriver, timeoutInSeconds);
   wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("LOCATOR")));
   

3. Clicking with JS

   JavascriptExecutor js = (JavascriptExecutor)driver;
   js.executeScript("arguments[0].click();", buttonToClick); //buttonToClick is WebElement
