Regex for input text box

Question

I have a text box for user input where user can enter only comma separated numbers. Comma at the end of the string is also allowed

I am done with regex for that

var regex=/^[0-9\,]+$/;

How to apply higher bound limit on each comma separated number?

lets say, maximum number is 10 digit

following is valid

11,22,333,555555 and

11,23,

following is invalid

111111111111111111111111,4,4

Answer 1

Use the following pattern:

var regex = /^[0-9]{1,10}(?:,[0-9]{1,10})*$/;

This says to match any number of 1 to 10 digits, followed by a comma and another 1-10 digit number, this quantity zero or more times.
