E: quick js question about calling functions

I would like to call the function when the enter key is pressed in an input box (input type="text"). I know about how to do it with buttons and links, but not with textboxes; it should not be a clickable object; I just want the user to be able to hit enter and have the function called. Thanks. 


Have a great day,
Alex

G'day Alex,
Yup it certainly can be done. For clickable objects such as 
buttons the tag
which I use goes along the lines of <input type="button" 
value="Click Me"

onclick="myFunction()"/> and with hyperlinks I use <a
href="javascript:myFunction()">Click Me</a>. It's also generally 
good
practice to put the functions in a separate .js file and add a 
<script
type="text/javascript" src="my_functions.js"></script> within the 
head

section of your page.



HTH.



Cheers.
AB

Hi all,
Just a quick question: in a webpage, I have a textbox.  I would
like the user to be able to hit the ENTER key in this box and
call a function, instead of needing to click a button.  The page
is a simple game meant to be played offline, so the page should
not go anywhere or reload itself.  Basically, I want the enter
key inside a textbox to take the place of a button.  Can this be
done?



Have a great day,
Alex
