I need to write a function that involves many components. It would be nice
to add a behavior to a form, like you have with a TextField, that would
construct a function that included all of the relevant components of that
form. The function I need to write looks like this:
function keyPressed()
{
if (window.event.keyCode == 49)
{
document.getElementById('button1').click();
}
if (window.event.keyCode == 50)
{
document.getElementById('button2').click();
}
if (window.event.keyCode == 51)
{
document.getElementById('button3').click();
}
...
}
<body onKeyPress="keyPressed()" ... >
Do you have any suggestions or ideas?
