Yep..that is how you would do it. Something like:
<input type="text" name="SomeName" onfocus="some_javascript_routine()"
onblur="..." value="...">
I know onfocus is when the control gets keyboard focus..I thin the onblur=""
is the one where the control loses focus whether its a tab or a mouse click
into another control. Your routine it calls would validate the field at that
time.
I wrote some javascript validation routines using Regular Expressions of
javascript so that when they submit the form it validates the whole form.
You simply put <input type="hidden" name="validate"
value="required,digits_only,phone,email,etc.."> right before a field you
want validated, and the form onsubmit="" calls the one function in
javascript that iterates over every field in the form. If an error occurs it
displays an image next to the field indicating its an error, and doesn't
submit the form.
