I figured it out. i was finally able to locate some sample code online that
changes it to a red color when the value changes. I still don't know how to
make it display a message such as "Value changed". I have a popup menu that
appears, but that doesn't seem efficient and probably aggravating. It's
weird how there seems to be a difficult and an easy way of doing things in
javascript.
echo "<input value='$streetnumber' name='txtStreetNumber' onchange='if
(this.value!=this.defaultValue) { fieldChanged(this) }'>";
function fieldChanged(val)
{
val.style.background='#FF0000'; //gives the background a red color
alert ("This field has changed its value. If you do not wish to save, please
exit the page");
}
