Mask javascript variable value -

i want mask javascript variable value.basically getting phone number fields value in variable , after getting want mask in other format.

i have tried jquery mask plugin mask control's string format.but want mask string variable.

ex:

let have phone string "0000000000" , storing in variable :-

var number ="0000000000" 

and after want mask in other formats.like-

1) number = number.mask('000-0000'); 2) number = number.mask('(000) 000-0000');

there similar question (javascript phone mask text field regex).

you can using regular expressions (see code working @ http://jsfiddle.net/bbewn/45/):

var value = '1234567'; var formatted = value.replace(/^(\d{3})(\d{4}).*/, '$1-$2'); 

notice each part of regular expression wrapped within parenthesis, (\d{3}) , (\d{4}) in example above, can referenced build formatted text string using $1 , $2 respectively.

if have n parts of regular expression wrapped within parenthesis, able reference them build formatted text string $1, $2, ..., $n respectively.

so, other format mention ((000) 000-0000), code this:

var formatted = value.replace(/^(\d{3})(\d{3})(\d{4}).*/, '($1) $2-$3'); 

you can find great javascript regular expressions reference @ https://developer.mozilla.org/en-us/docs/web/javascript/guide/regular_expressions
