title: document.getElementsByTagName('select') - select only from particular form
body: <p>I'm trying to select drop-downs and check them, so I'm using this code to do so -  <code>document.getElementsByTagName('select');</code> but the problem I'm facing is that I've got several forms on one page and I want to choose only drop-downs from form called <code>myform3</code> for example! </p>
  
  <p>I found one example it looks like this - <code>myform3.document.getElementsByTagName('select');</code>  <strong>but it only works in IE</strong></p>
  
  <p>Could you tell me how to do that in every browser?</p>
