how to make the button default when press enter

[kay lin]

Hi all:
Could somebody let me know how to make the form default to submit button when user presses "ENTER" key as they finish filling out the form?


Many thanks

Well, if you have a function, that will return true, if "they finish filling out the form", you can just have onkeypress handler for the whole document, and submit a form.

Do something like that code (Note, it is not tested, different pieces cut&pasted from different places)

 
function isTheyFinishFillingOutTheForm(){
   return true; //you need to implement that
}
 
   if (document.getElementById&&!document.all) {
       // NS6
        document.captureEvents(Event.KEYPRESS);
        document.onkeypress= NSkeypress;
   }
 
   if (document.layers) {
        document.captureEvents(Event.KEYPRESS);
        document.onkeypress= NSkeypress;
   }
 
   if (document.all) {
     document.onkeypress=IEkeypress;
   }
 
   function NSkeypress(e)
   {
       if (e.which == 13 &&  isTheyFinishFillingOutTheForm()) {
          //submit form here
       }
       return true;
   }
 
   //for IE
   function IEkeypress()
   {
      if (window.event.keyCode == 13 && isTheyFinishFillingOutTheForm()) {
         //submit form here
      }
      return true;
   }
