title: javascript form submit issues
body: <p>There is one form i have and a user can click on preview button or save button , both buttons send data to different locations.</p>
  
  <p>Here is the relevant code:</p>
  
  <pre><code>prevAction = location.href;
  document.getElementById('preview').value='true';
  document.getElementById('form1').target='_blank';
  document.getElementById('form1').action = 'http://www.xxx.com/do/preview';
  document.getElementById('form1').submit();
  document.getElementById('form1').target='';
  document.getElementById('preview').value='';
  document.getElementById('form1').action = prevAction;
  </code></pre>
  
  <p>Now it works fine with 99.9% users , however only 2 users have complained so far that it doesn't work for them. One of them is using mac and says it doesnt work in safari and firefox both. When he hits preview , the form data doesn't seem to be post and after hitting preview if they hit save , the form data doesnt go thru as well.Can you guys tell me what i am doing wrong here.</p>
  
  <p>Also one thing which might be relevant .. i mootools is loaded in the head section but this piece of code doesnt make use of it.. can this have an effect?</p>
