Adding extra zeros in front of a number using jQuery?

Question

I have file that are uploaded which are formatted like so

MR 1

MR 2

MR 100

MR 200

MR 300

Answer 1

By adding 100 to the number, then run a substring function from index 1 to the last position in right.

var dt = new Date();
var month = (100 + dt.getMonth()+1).toString().substr(1, 2);
var day = (100 + dt.getDate()).toString().substr(1, 2);

console.log(month,day);

you will got this result from the date of 2020-11-3

11,03

I hope the answer is useful
