Selenium - Handle Iframes/Frames easily

Hi all,
Here I am going to list out ways to handle iFrames parts in selenium automation as I read from some sites.
Example-1:

1. //Gmail Body is an iframe. Here we are writing content to body of new mail in selenium
2. var bodytext="Sample Body Text for Testing";  
3. var iframe_locator = "css=table:contains('Subject:') +*  iframe\";
4. var iframe_body = selenium.browserbot.findElement(iframe_locator).contentWindow.document.body;
5. if (browserVersion.isChrome) {    
6.   iframe_body.textContent=bodytext;
7. }  else if(browserVersion.isIE) {
8.   iframe_body.innerText=bodytext;
9. }

Example-2:

1. //Switch to the frame - use index/name
2. driver.switchTo().frame("frameName"); 
3. //Also you can use like 
   SwitchTo.Frame(relative=up)
   SwitchTo.Frame(relative=top)
   

   
   

   // Do your operations in frame 
4. //Switch back to the parent window
5. driver.switchTo().defaultContent();
