Testing a checkbox

[Trevor L.]

I have this code

<form action="" id="form1" name="form1">
Please answer yes or no <br/>
<input type="checkbox" id="yes" name="yes" />Yes <br/>
<input type="checkbox" id="no" name="no" />No <br/>
<input type="button" value="Send" onclick="sendmess()" />
</form>

This results in this being displayed
Please answer yes or no
Yes
No

No matter whether I tick or don't tick either box, the value returned is on.
e.g. I have a function:
function sendmess()
{
alert ('YES ' + document.forms['form1'].elements['yes'].value +
' NO ' + document.forms['form1'].elements['no'].value )
return
}

On clicking Send, all of these return the same result
Yes
No

Yes
No

Yes
No

Yes
No


Yes
No

The result is an alert:
YES no NO on

How do I test which box has been ticked ?

You haven't added the Value attribute.

<form action="" id="form1" name="form1">
Please answer yes or no <br/>
<input type="checkbox" id="yes" name="yes" value="Yes" />Yes <br/>
<input type="checkbox" id="no" name="no" value="No" />No <br/>
<input type="button" value="Send" onclick="sendmess()" />
</form>

Thomas,

This makes no difference whatsoever

I changed it to
<input type="checkbox" id="yes" name="yes" value="Yes"/>Yes <br/>
<input type="checkbox" id="no" name="no" value="No" />No <br/>

but no matter which checkbox is checked or not, using this code to display
the result
document.forms['form1'].elements['yes'].value
document.forms['form1'].elements['no'].value
gets the result
Yes
No

Is the problem with the Javascript ?

 

[Thomas A. Rowe]

The problem is with your JavaScript. Are you also using FP Form Field validation, if so that would
be a reason for it not working.

Thanks Thomas,
Stefan pointed me in the right direction
http://www.irt.org/articles/js027/index.htm

My JS needs to display document.forms['form1'].elements['no'].checked

No, I am not using FP Form Field validation

See http://www.irt.org/articles/js027/index.htm

Stefan,

I forgot to say thanks. As stated in the reference, the correct property to
test is "checked". When I did this all was fine.

 

[Stefan B Rusynko]

you're welcome
