how to check values entered are in greater order...using javascript..


        The addcandidate function ,will add two textboxes of count 10 , I need to validate , that
entered values of textboxes follows  this...
1.Candidate --> Entered value should be greater always to the previous candidate texbox
1.Percent------->Entered values can be greater or equal to the previous percent textbox ...

how can i validate this peculiar condition plzz help??

  i.e (entered textbox value should be like this)
  candidate percent
   15              7
   16              9
   20             10
   22             12
   25             12
   30             20

if any entered values goes wrong should alert....
<a href="javascript:;" onclick="addcandidate()">Add candidatete</a>
    <input type="text" name="candidate1"   id="candidate1" runat="server"  />
    <input type="text" name="percent1" id="percent1" runat="server"  />
    <input type="text" name="candidate2" id="candidate2"  runat="server"  />

i see CoolerSport's answer goes all well.

And follow below for his code should work fro you.

name all canditate textbox as canditates and get lenth of textboxes using
var len = document.all.item("canditates ").length; and use in place of 10 in line -- for (var i = 1; i <= len; i++)


And loop  accordingly.

cheers,

Last one lacks closing tag, so it doesn't render properly in EE :D
