For example I have a form with field: "employee_name".
When people input empoyee name into it, ex: "John Smith".
Sometime there is a space in the front of the string like this: " John Smith".
How can I remove that space programatically? Could anyone advice me
For instance: which event should I use? method etc.
If you have a little of free time, could you decribe as detail as you can
about the way to solve problem?
