javascript - Submit form without page reloading

Question

I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form...

So anybody who wants can send a tip of the ad to some friends email-adress.

I am guessing the form must be submitted to a php page right?

<form name="tip" method="post" action="tip.php">
  Tip somebody: 
  <input 
    name="tip_email"
    type="text" 
    size="30" 
    onfocus="tip_div(1);" 
    onblur="tip_div(2);"
  />
  <input type="submit" value="Skicka Tips" />
  <input type="hidden" name="ad_id" />
</form>

When submitting the form, the page gets reloaded... I don't want that...

Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery...

I've found what I think is an easier way. If you put an Iframe in the page, you can redirect the exit of the action there and make it show up. You can do nothing, of course. In that case, you can set the iframe display to none.

<iframe name="votar" style="display:none;"></iframe>
<form action="tip.php" method="post" target="votar">
    <input type="submit" value="Skicka Tips">
    <input type="hidden" name="ad_id" value="2">            
</form>
