Making a Submit Button appear dynamically

[codehead]

Hello All:

I want to make a Submit Button appear when a check box is checked on a form. Does anyone know how to do this or can anyone point me to a similar example that I could adapt to my usage?

Thanks!

this is actually a javascript question..post in that forum for a better answer, but here is an example code...

<form action="post" action="your_processor" onsubmit="return false;"> 
<input type ="checkbox" name="agree" value="anything"> 
<b>Click me or the buck stops here.</b> 
<input type="submit" name="submitbutton" onClick="check_agree(this.form);" value="Go"> 
</form> 
<script language="javascript"> 
function check_agree (form) { 
if (form.agree.checked) { 
form.submitbutton.disabled = true; 
form.submit(); 
} 
else { alert('if you don\'t agree, we set you free.'); } 
} 

</script>

Hi DNG,

There seems to be a logic flaw....when I check the checkbox, I get the "else" message, instead of the Submit Button being disabled.

Thanks!

are you sure that you named the form fields correct...check your submit button name and check box name

the above example runs fine for me...

this link also has another similar code sample...take a look at it and adjust it to your needs...

Could it not be working because I'm using multiple checkboxes (under the same checkbox name) that are being populated from a database?

<table>
<tr>
<% do while not tl_org.EOF %>
<td><input type="checkbox" name="TL_ORG" value="<% = tl_org("ORGANIZATION") %>" onClick="disSubBut(this.form);"></td><td><strong><% = tl_org("ORGANIZATION") %></strong></td>
<% tl_org.movenext %>
<% Loop %>
</tr>
</table>

thats should not be a problem i guess because in anycase we are doing

if (form.[red]yourcheckboxname[/red].checked)

did you post this question javascript forums...i am sure you will get a better reply there...
