Here's a basic example:

Code: Select all

<script type="text/javascript">
var ray=
{
validate:function(el)
   {
   var chckArr = el.getElementsByTagName('input'),check=false;
   for(var i = 0; i < chckArr.length; i++ )
      if(chckArr[i].getAttribute('type')=='checkbox')
         check=chckArr[i].checked?true:false;

   if(!check)
      {
      alert('You must click any of the checkbox to proceed to the delete part.');
      return false;
      }
   }
}
</script>
<form id="myform" onsubmit="return ray.validate(this)">
<input type="checkbox">
<input type="checkbox">
<input type="checkbox">
<input type="checkbox">
<input type="submit" value="delete">
</form>

thanx alot 4 ur help..i really appreciate it..but there is a small problem here..the script is valid only if the last checkbox is ticked..let's say i have 10 checkboxes, if i don't click any of those boxes, the alert message will pop up..it's good..but, if i click all the boxes excluding the last box, the alert message also popped up. can u fix this prob for me?..thanx again..

Just replace this part:

Code: Select all

check=chckArr[i].checked?true:false;


...with:

Code: Select all

check=chckArr[i].checked?true:check;

forgive me I'm a bit of a rookie
so I would like to use the same code, except I want the button at the end to be a link.



so I just replaced the last line of

<input type="submit" value="A link for megan">

With

<FORM METHOD="LINK" ACTION="the url">
<input type="submit" value="Tester">
</FORM>

when I use this by itself it works fine but with your code it dosent work.
can't figure it out...
