Selenium WebDriver: How to wait for iFrames to load completely?

Question

I'm testing a page with an iFrame whose contents are generated by JavaScript dynamically. I have to wait for the iFrame loaded completely to make sure that all the elements are present. I tried the following code, it didn't work.

WebDriver frame = wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("frmMain"));

I also tried to wait for some element in the iFrame to be present. It didn't work, neither.

Any help would be greatly appreciated, thanks!

Answer 1

Select any element on IFrame which takes maximum time to load e.g. any button or image and the wait using the following code.

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated((By
                .name("element"))));

Or rather you can wait for for iFrame to appear and then switch to it and then use the above statement !
