Submit The Form When The User Presses Enter
Different browsers have different default behaviors about what to do when the user hits enter in a form. MSIE almost always submits the form, while Netscape will often just beep at you. Although it's usually best to leave the default browser behavior as it is, for some forms people just naturally tend to hit "enter" when they are ready. This is particularly true for login forms. With a little JavaScript we can set the form to submit on enter.
First, copy this script exactly as-is into the <HEAD> section of your document:
<SCRIPT TYPE="text/javascript">
<!--
function submitenter(myfield,e)
{
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (keycode == 13)
{
myfield.form.submit();
return false;
}
else
return true;
}
//-->
</SCRIPT>
For each field which should submit the form when they hit enter add an
onKeyPress attribute like this:
<FORM ACTION="/cgi-bin/html/mycgi.pl">
name: <INPUT NAME=realname SIZE=15><BR>
password: <INPUT NAME=password TYPE=PASSWORD SIZE=10
onKeyPress="return submitenter(this,event)"><BR>
<INPUT TYPE=SUBMIT VALUE="Log In">
</FORM>
Add the attribute like it is in the example. No modification is needed. This gives us this form:
