格式化数字为金额格式
export const formatMoney = (number, decimals = 0, decPoint = '.', thousandsSep = ',') => {
number = (number + '').replace(/[^0-9+-Ee.]/g, '')
let n = !isFinite(+number) ? 0 : +number
let prec = !isFinite(+decimals) ? 0 : Math.abs(decimals)
let sep = (typeof thousandsSep === 'undefined') ? ',' : thousandsSep
let dec = (typeof decPoint === 'undefined') ? '.' : decPoint
let s = ''
let toFixedFix = function (n, prec) {
let k = Math.pow(10, prec)
return '' + Math.ceil(n * k) / k
}
s = (prec ? toFixedFix(n, prec) : '' + Math.round(n)).split('.')
let re = /(-?\d+)(\d{3})/
while (re.test(s[0])) {
s[0] = s[0].replace(re, '$1' + sep + '$2')
}
if ((s[1] || '').length < prec) {
s[1] = s[1] || ''
s[1] += new Array(prec - s[1].length + 1).join('0')
}
return s.join(dec)
}格式化金额组件
尤雨溪git下载，这里是引入
const digitsRE = /(\d{3})(?=\d)/g
export function currency(value, currency, decimals) {
value = parseFloat(value)
if (!isFinite(value) || (!value && value !== 0)) return ''
currency = currency != null ? currency : '$'
decimals = decimals != null ? decimals : 2
var stringified = Math.abs(value).toFixed(decimals)
var _int = decimals ?
stringified.slice(0, -1 - decimals) :
stringified
var i = _int.length % 3
var head = i > 0 ?
(_int.slice(0, i) + (_int.length > 3 ? ',' : '')) :
''
var _float = decimals ?
stringified.slice(-1 - decimals) :
''
var sign = value < 0 ? '-' : ''
return sign + currency + head +
_int.slice(i).replace(digitsRE, '$1,') +
_float
}使用
导入js文件，因为是根据函数名导出，所以，导入需要进行解构
import { currency } from "@/util/currency";
export default {
.........
// 局部过滤器
filters: {
currency: currency,
},
} 格式化组件使用
<div class="item-total">
<span>{{totalPrice | currency('$')}}</span>
</div>如果在全局使用
main.js
import {
currency
} from "@/util/currency";
Vue.filter('currency', currency)以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
