Topic: enabling and disabling a checkbox

Subject: enabling and disabling a checkbox
Date Posted: 27 February 2003 at 7:41am

Can someone please help me with this.
I have already come up with the code but it is not working.
What I really need out of this code is to disable all checkboxes except the first one so that processing can be done with that first one.
Once processing is complete with the first one, a checkmark is placed on the checkbox disabling and the next checkbox is enabled for processing.
Once that next one is processed, a checkmark is placed on the checkbox beside it disabling it while enabling the next checkbox for processing until all are processed.
So far, once a checkmark is placed on the first one, everything is disabled.
here is the code i have so far:

<HTML>
<HEAD>
<TITLE>enable</TITLE>
<script language="javascript">
function enable(inBox){
//check to make sure that the last box hasn't been reached.
lastBox = 3;
//disable current box
eval("document.myForm.cb" + inBox + ".disabled = true");
//enable next box (if not finished)
if (inBox < lastBox){
    inBox = inBox + 1;
    eval("document.myForm." + inBox + ".disabled = false");
}
}
</script>

</HEAD>
<BODY>
<form name="myForm">
<table>
<tr>
    <td>First Order
      <input type=checkbox name=cb1 onClick="enable(1)">
    <td>Second Order
      <input type=checkbox name=cb2 onClick="enable(2)" DISABLED>
    <td>Third Order
       <input type=checkbox name=cb3 onClick="enable(3)" DISABLED>
    </td>
   </tr>
</table>
</form>
</BODY>
</HTML>

</HEAD>
<BODY>
<form name="myForm">
<table>
<tr>
    <td>First Order
          <input type="checkbox" name="cb1" id="cb1" onClick="enable(1)">
     </td>
    <td>
          Second Order
          <input type="checkbox" name="cb2" id="cb2" onClick="enable(2)" DISABLED>
     </td>
    <td>
          Third Order
       <input type="checkbox" name="cb3" id="cb3" onClick="enable(3)" DISABLED>

btw, to save from copying, pasting, and saving, http://216.119.87.228/sections/playground/scripts/enableCheck.asp - here's that above code running :)

MorningZ, thanks a bunch but it is still not working correctly.

The only time the next checkbox is actived should be after the current checkbox is checked.

For instance, if the first checkbox for first order has not been checked, the rest should be disabled making it impossible for anyone to check them until the first one is checked off as being completed.

again, thanks for the help!

so are you saying/asking that the code needs to also deactivate a later checkbox if a user unchecks a box?

ya know, i'd really try to help, but you need to explain better
