javascript - Check if value matches mask -


i have input has mask of date __/__/____. stored in variable. there way detect if matches mask properly?

the event binded on blur, returning values 22/12/___.

is there way detect if fits scheme integers , slash or doesn't?

$('#btn').click(function() {    value = $('#my-input').val()   // should in format 99/99/9999 , not 12/12/12__     // here need check if in right format.    if (checkformat(value)) {     } } 

you can use regex validate this.

var regex_check = /^\d{2}\/\d{2}\/\d{4}$/ ; 

//edit - vanilla javascript

 function foo(date) {       var regex_pattern = /^\d{2}\/\d{2}\/\d{4}$/ ;       var check = new regexp(regex_pattern);       var res = check.test(date);        // return true or false       return res;     }
