When you TAB from one textfield to the next in a HTML form and use the onChange event of the first field to check the value, the focus will go to the next field, even if the return value in the onChange event was false. If you want to check for a value, the onChange event is the right place/time to do so, but if a typed textfield value was incorrect, you don't want to loose the focus on that field.
Reproducible: Always
Steps to Reproduce:
Use the HTML and javascript below to see what happens and compare with the way Internet Explorer handles it.
<html>
<body>
<script type="text/javascript">
function fieldIsValid(field){
if (field.value != "HellO WorlD"){
alert("Value is not ok.");
field.value = "";
return false;
} else{
alert("Value is ok.");
return true;
}
}
</script>
<form>
<input type="text" onChange="return fieldIsValid(this)">
<br>
<input type="text" >
</form>
</body>
</html>

Don't think so. Ref my comment on bug 267675
This bug describes the fact that ff dos'nt respect the return
value from onchange-handler and always selects next/previous/any control
according to the action which triggered the onchange-event (tab, shift/tab,
mouse-click)
The problem may be handled by:
function myOnChange(field)
{
if (field.value!='Ok value')
{
window.selectedField = field;
if (!/^Mozilla/.test(navigator.userAgent)) { field.focus(); }
else { setTimeout('window.selectedField.focus()', 1); } // Workaround for mozilla 'bug'
return false; // Respected by IE only
}
return true;
}
.. but it would have been nice if it could be fixed to work as in IE
