Vue.js货币格式化函数
函数:
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, '$1,') + _float }
引入:
import {currency} from './../util/currency'
定义局部过滤器:
filters:{ currency:currency },
使用:
<div class="item-total"> Item total: <span class="total-price">{{totalPrice|currency('$')}}</span> </div>
全局过滤器:在main.js
import {currency} from './util/currency'
Vue.filter("currency",currency);
使用:
<div class="cart-tab-4"> <div class="item-price-total">{{(item.productNum*item.salePrice)|currency('$')}}</div> </div>
效果:
