delimited-input v0.5.0

delimited-input

Proof-of-concept

Reading long numbers or codes is hard without some kind of delimiter to provide pacing or idea of the scale. This library provides support for formatting user input as it's written.

This library is fairly early in development but it should provide some basic support for formatting rules already.

Example input and output

• Big number: writing 7283947 shows like this 7,283,947
• Credit card: writing 4265827561095863 shows like this 4265 8275 6109 5863
• Product code: writing abj39lv2jvk3 show like this abj3-9lv2-jvk3

Test at the project homepage.

Example usage

Auto-format user input as it is modified:

<input id="numeric_input" type="text" value="7,283,947"/>

var thousandsDelimiter = DelimitedInput(",", 3);
document
  .getElementById("numeric_input")
  .addEventListener("keydown", thousandsDelimiter);

Node

var DelimitedInput = require("delimited-input");

RequireJS

requirejs(["delimited-input"], function(DelimitedInput) {
  /*...*/
});
