element-ui实现input输入框金额数字添加千分位组件

创建一个amountFormat.js

const MoneyTest = /((^[1-9]\\d*)|^0)(\\.\\d{0,2}){0,1}$/;// 金额添加千分位const comdify = function (n) {if(!n) return n;let str = n.split('.');let re = /\\d{1,3}(?=(\\d{3})+$)/g;let n1 = str[0].replace(re, "$&,");return str.length > 1 && str[1] ? `${n1}.${str[1]}` : `${n1}.00`;};//去除千分位中的‘，’const delcommafy = function (num){if(!num) return num;num = num.toString();num = num.replace(/,/gi, '');return num;};const valdateFn = function (rule,val,cb) {setTimeout(() => {if(val) {let inputVal = delcommafy(val);if (rule.test(inputVal)) {cb()} else {cb('只能是数字金额,最多两位小数')}}cb()})}// 验证金额数字可以为负数const moneyValid = function (rule,val,cb) {valdateFn(/((^-?[1-9]\\d*)|^-?0)(\\.\\d{0,2}){0,1}$/,val,cb);};// 验证金额数字不可以为负数const moneyNValid = function (rule,val,cb) {valdateFn(MoneyTest,val,cb);};// 获取输入框的值// const getInputValue = function (el) {//     let inputVal = el.target.value || '';//     return comdify(delcommafy(inputVal));// };// 获取输入框的值export const getInputValue =  (el) =>{let inputVal = el.target.value || '';return comdify(delcommafy(inputVal));};

vue页面中的使用

import { getInputValue } from "@/utils/amountFormat.js";

template中：<el-inputstyle="width: 220px"placeholder="请输入注册资本"v-model.number="formData.registCaptial"@blur="inputMoneyFomet($event, 'registCaptial')"clearable:disabled="detailFlag === 1 ? true : false"></el-input>javascipet中：inputMoneyFomet(el, name) {this.formData[name] = getInputValue(el);},
