okay thankyou, its working  

but this way absolutely looks dangerous and odd by changing the default value of messager option button..  
because every time i want to reset the button value i need to put the $.messager.defaults.cancel = 'Cancel' value again..

by the way i saw the custom parameter of ok and cancel button in documentation, but i find no example or explanation about this..

Thankyou again..
