Rails spinoffs - Apr 2007 - Help:How2Build enterToTab() function with prototype.js

HI,brothers
There are two inputs(type=text) on a page,when i type something in the
first input and then press "Enter" on the keyboard, i wanna put my
cursor to the second input automatically.

I then wrote a function called "enterToTab" to deal with that,as
below,but it failed.Can u help me to fix my enterToTab function?Thx.

function enterToTab(e){
  if(e.keyCode==Event.KEY_RETURN){
    e.keyCode=Event.KEY_TAB;
  }
}

Element.observe(window,''load'',function(){
  $(''input1'').observe(''keydown'',enterToTab);
});

I debug the code above with firebug,it shows "setting a property that
has only a getter",but i don''t know how to fix...

Your better option would be to detect the enter key as you have but then 
to call the focus() method of the other input field.  This should move 
the cursor.  The error your getting is a result of trying to change the 
keyCode of the error object, which you cannot do.
