HTML/Javascript - Submitting a form using an image map

Here is a demo of the code
http://www.polarhome.com:793/~ed301/vote.html

I need the form to be submitted when the individual image mapped sections are clicked passing the variable value=(1 to 5) to the form submission.


Heres the code

<form method=post>
<!-- This line would normaly be <input type=hidden name=itemid value="<?=$id?>"> obtaining the $id from the php page-->
<input type=hidden name=itemid value="1">
<table width=30%>
<tr>
<!-- Content -->
</tr>
<tr>


<img src="vote.jpg" name=map width="120" height="50" border="0" usemap="#Stars">
<map name="Stars">
  <area shape="rect" coords="25,21,40,41" name=rateit value=1 onClick="this.form.submit();" onmouseover = "document.map.src = '1-star.jpg';" onmouseout = "document.map.src = 'vote.jpg';">
  <area shape="rect" coords="39,21,54,41" name=rateit value=3 onClick="this.form.submit();" onmouseover = "document.map.src = '2-star.jpg';" onmouseout = "document.map.src = 'vote.jpg';">
  <area shape="rect" coords="53,21,68,41" name=rateit value=3 onClick="this.form.submit();" onmouseover = "document.map.src = '3-star.jpg';" onmouseout = "document.map.src = 'vote.jpg';">
  <area shape="rect" coords="67,21,82,41" name=rateit value=4 onClick="this.form.submit();" onmouseover = "document.map.src = '4-star.jpg';" onmouseout = "document.map.src = 'vote.jpg';">
  <area shape="rect" coords="81,21,96,41" name=rateit value=5 onClick="this.form.submit();" onmouseover = "document.map.src = '5-star.jpg';" onmouseout = "document.map.src = 'vote.jpg';">
</map>


</tr>
</table>
</form>

Thanks Ed301

 

Could you just link each of the elements in the image map to some kind of dynamic url to mimic the data your form would have sent?

eg
replace
onClick="this.form.submit();"

with

href="/mypage.php3?itemid=<?=$id?>&vote=1"
href="/mypage.php3?itemid=<?=$id?>&vote=2"

etc

 

Thanks for your reply I have used your suggestion and added urls to the mapped sections. I just need to make sure google doesnt index the page with the voting number.
