Package Exports

bill-counter-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bill-counter-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Installation

download

npm install bill-counter-js -S

How to use

NOTE

You must run the function after 'DOMContentLoaded' event.

Similar to jquery's $(document).ready().

DOMContentLoaded is a web standard and jQuery is not a web standard.

Browser

<script src="https://unpkg.com/bill-counter-js@0.0.6/dist/bill-counter.min.js"></script>

<script>
  document.addEventListener('DOMContentLoaded', () => {
    $B.countByN('selector-id', targetMoney, N, interval);
  });
</script>

see example source

ESM

import { $B } from 'https://unpkg.com/bill-counter-js@0.0.6/dist/bill-counter.esm.js';

document.addEventListener('DOMContentLoaded', () => {
  $B.countByN('selector-id', targetMoney, N, interval);
}

see example source

Common JS

const { $B } = require('bill-counter-js');

$B.countByN('selector-id', targetMoney, N, interval);

API Documents

1. Count by N

$B.countByN(id, end, n, (interval = 0.1));

Count the numbers by n.

Perhaps most similar to the counter.

2. Fast counting

$B.countFast(id, end, (duration = 100));

Count any number in a certain amount of time.

I think it will be very effective as an animation.

3. Count Object

The above two functions only worked for DOM objects. But sometimes you need to modify the Model, not the View, like Vue.js. Try using countObjectByN or countObjectFast.

It is basically the same except that the first argument is object.

Copy the code below and run node source.js!

const { $B } = require('bill-counter-js');
const obj = {
  value: 0,
};

$B.countObjectByN(obj, 1000, 1, (interval = 1));

function test() {
  return new Promise(resolve => {
    let i = 0;
    const sid = setInterval(() => {
      console.log(obj);
      i++;
      if (i === 1000) {
        clearInterval(sid);
        resolve();
      }
    }, 1);
  });
}

(async () => {
  await test();
})();

4. Locale Setting (Formatting)

// default
$B.localeOptions = {
  format: true,
  locale: 'en-US',
  currency: 'USD',
};

format: Do you format in currency? (true = yes)
locale: What language do you speak? (Learn More)
currency: What currency are you using? (Learn More)

5. Define your formatter

The default formatter uses the ECMAScript Internationalization API. (INTL) If you don't like this, define your own formatter.

$B.formatStyler = (number) => {
  // your formatter!
}

If you want to change back to the default style,

run $B.formatStyler = $B.defaultFormatStyler;
