How to handle iFrames in Selenium WebDriver?

In Webdriver, you should use driver.switchTo().defaultContent(); to get out of a frame.

You need to get out of all the frames first, then switch into the desired frame.

driver.switchTo().defaultContent(); // you are now out of the frames

driver.switchTo().frame("your frame id comes here");// move to the desired frame

Why shouldn’t I just use * for my postMessage?

Browsers have a same-origin policy to prevent different domains from interacting with each others’ DOMs. 

This is why Stripe is safe to use. Because Stripe’s credit card input field is inside Stripe’s iframe, even if the iframe is on a site called scamwebsite.com, there is no way for scamwebsite.com to actually query the DOM to see what your credit card info is.

However, browser vendors realize that there are situations where you want to be able to communicate with an iframe, like maybe you want to listen for when Stripe Checkout is done so you can proceed to the next page. This is where postMessage comes in. 

https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

postMessage offers a messaging API so that you can communicate with the iframe, as long as you and your iframe both explicitly expect this communication.

And the way you would use it would just be like this:

iframeWindow.postMessage(’saying hi to my iframe’, ‘https://stripe.com’)

Now, the documentation says that the 2nd argument, targetOrigin, can actually be a wildcard. That makes things easy. 

iframeWindow.postMessage(’saying hi to my iframe’, ‘*’)

Why wouldn’t I just always use that?

Well, let’s say you are sending pretty sensitive info through postMessage. If you knew the destination was a reputable company like Stripe, you probably would not bat an eye. However, what if Stripe’s iframe decided to change its own location? What if it redirected itself to thisisascam.com? Then, your postMessage would still be received, and thisisascam.com would have the chance to receive your sensitive info.
