JS HTML Interaction and Radio Buttons?

[robdunfey]

Hi,

Two questions.

1) I cant seem to be able to write text to a textarea from my javascript file. The textarea resides in a form, in a table, on a html page stored in the same folder as the js file? I have tried using things like document.getelementbyid("myform&quot.value="hello" and swapping document for top (whatever that means?) but cant get it to work?

2) I have a set of radio buttons, in a form, in a table in a html page. I want to execute js code in a js file when any of the buttons is a)checked or b)unchecked? Does anybody now how this may be done? Or the location of a simple to follow example?

Kind Regards,

Rob

try the following

<form name=&quot;myForm&quot;>
<textarea name=&quot;test&quot;></textarea>
</form>
<script language=&quot;javascript&quot;>
document.myForm.test.value='Hello';
</script>

each radio button has an onclick event, which should do what you need.

thanks for the swift reply.

i get an error saying document.myForm.test is null or not an obeject? does it make any difference that the html and js are stored in separate files?

thanks,

Rob

Hi,

I have it working. I changed 'document' to 'top', I dont know why this makes a difference but if someone could explain that would be great.

As for the radio button on click, how would you deal with it losing focus? i.e. onunclick?


Thanks,

Rob

The onclick event is called whenever a radio button is clicked - to turn it off or to turn it on.

Rob,

'top' refers to the top-level window object when your page has frames.

use onblur to capture an element losing focus.
