Need to switch between frames in Selenium

Question

I have a WebDriver code and need to switch between two frames. I recorded the testcase using selenium IDE and when expored the Java code, I got the values as
selectFrame relative=top select Frame=middle Frame

But the problem is, its not able to recognize relative=top and middleFrame. How to solve this error in WebDriver. I'm using Java?

Answer 1

For switching between frames, use driver.switchTo().frame(). First locate the frame id and define it in a WebElement. Ex:- 

WebElement fr = driver.findElementById("id");

Then switch to this frame using this code:- 

driver.switchTo().frame("Frame_ID");

This is how it should fially look like:

WebElement fr = driver.findElementById("theIframe");
driver.switchTo().frame(fr);

Then to move to default frame, use:- 

driver.switchTo().defaultContent();
