number-flip v1.2.3
number-flip
Change number with flipping animation
install
$ npm install --save number-flip
usage
import number-flip
import { Flip } from 'number-flip'
use it!
create one and make it flip immediately:
new Flip({
node: $('.flip'),
from: 9527,
to: 42
})
flip one with delay:
new Flip({
node: $('.flip'),
from: 9527,
to: 42,
delay: 1 // second
})
create one and flip it later:
const el = new Flip({
node: $('.flip'),
from: 9527
})
el.flipTo({to: 42})
customize animation duration:
new Flip({
node: document.querySelector('.flip'),
from: 9527,
to: 42,
duration: 2 // second
})
more complex usage
new Flip({
node: document.querySelector('.flip'),
from: 73,
to: 25,
duration: 2,
delay: 1,
easeFn: function(pos) {
if ((pos/=0.5) < 1) return 0.5*Math.pow(pos,3);
return 0.5 * (Math.pow((pos-2),3) + 2);
},
// for more easing function, see https://github.com/danro/easing-js/blob/master/easing.js
systemArr: ['零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖']
})
CSS customizable:
HTML structure of a 3-digits flip would be like:
.number-flip
.ctnr.ctnr0
.digit*10
.ctnr.ctnr1
.digit*10
.ctnr.ctnr2
.digit*10
The height / width of .number-flip
is based on the height / width of .digit
, you can customize the size by changing the css of .digit
:
.number-flip { ... }
.ctnr { ... }
.digit { ... }
or you can rename it in config:
new Flip({
containerClassName: 'c',
digitClassName: 'd',
separatorClassName: 's'
})
separator:
Spearator allowed
new Flip({
node: $('.flip'),
from: 95279527,
separator: ','
})
even more
new Flip({
node: $('.flip'),
from: 95279527,
separator: ['万', '亿', '兆'],
separateEvery: 4
})
syntax
var flipInstance = new Flip(options)
flipInstance.flipTo(instanceOptions)
return value

.flipTo
takes one instanceOptions
, so you can start the flip animation whenever you want.

defaults to 0.5 second.delay
optional

.easeFn
optional
: A easing function to be executed. If not specified,easeFn
defaults easeInOutCubic.systemArr
optional
