View Full Version : [SOLVED]How to validate a form?

24 Jan 2008, 7:29 AM
i wrote a formpanel
the vtype of its items are working well,
i means if the input is not legal by my set, the tipMsg will show
but i can still click the button sumbit

so i catch the onsumbit events, and want to write some code here to cancel the sumbit action when the input data is not legal

but i find the method return value of Ext.form.VTypes is void
i don't know how to validate with Extjs

could someone tell me the right way to cancel user sumbit when the input data is not legal

in general if you are wanting to do some advanced form validation before submitting you would write your own submit handler rather than relying on any built-in handler. Also the form.isValid() and form.isDirty() methods may be of use to you.
