vue 自定义过滤器 格式化金额（保留两位小数）

1、js部分

import Vue from 'vue'Vue.filter('money', function(val) {val = val.toString().replace(/\$|\,/g,'');if(isNaN(val)) {val = "0"; } let sign = (val == (val = Math.abs(val)));val = Math.floor(val*100+0.50000000001);let cents = val%100;val = Math.floor(val/100).toString();if(cents<10) {cents = "0" + cents}for (var i = 0; i < Math.floor((val.length-(1+i))/3); i++) {val = val.substring(0,val.length-(4*i+3))+',' + val.substring(val.length-(4*i+3));}return (((sign)?'':'-') + val + '.' + cents);})

2、html 部分

<template><div id="box"><p style="text-align:center;">总金额: {{ this.money | money}}</p></div></template><script>import './filter/filter.js'export default {data () {return {money: 1000000.89}},}</script>
