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 = "";
    }
    let sign = (val == (val = Math.abs(val)));
    val = Math.floor(val*+0.50000000001);
    let cents = val%;
    val = Math.floor(val/).toString();
    if(cents<) {
       cents = "" + cents
    }
    for (var i = ; i < Math.floor((val.length-(+i))/); i++) {
        val = val.substring(,val.length-(*i+))+',' + val.substring(val.length-(*i+));
    }

    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>
