maskedit input onBlur() problem.

maskedit input onBlur() problem.

Hi,
The maskedit clear the input on lost focus  (onBlur), in my case i'm using the onBlur function of the input for some function. 
the onBlur function that i'm using coms first and the value of the input is "_________" 
and in my function i'm chaking if myText.value == "" and its not, the value is "_________" and its cozing me problems.
is the any way to forceing the masked input to do the clear of the input and then to do my function?

thanks
