Hey, I am new to jQuery , I want to check onblur on input box this format cda 123 . mean first 3 characters space and 3 integers. Usually I see that code is written on Input
Just use some jQuery input mask plugin, for example this http://digitalbush.com/projects/masked-input-plugin/
Then you can use:
jQuery(function($){ $(".InputMask-cccsnn").mask("aaa 999"); });
