1. src目录下新建filters目录，filters目录里新建index.js文件（写过滤方法）
import moment from 'moment/moment'
const toFixed = (value = 0) => {
let val = Math.round(value * 100) / 100
return val.toFixed(2)
}
const dateFormat = (dataStr, pattern = 'YYYY-MM-DD HH:mm:ss') => {
// 判断数据如果为空返回'--' 否则返 回日期
if (!dataStr) {
return ' -- '
}
return moment(dataStr).format(pattern)
}
export { toFixed, dateFormat }
2. main.js里面注册filters
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import ElementUI from 'element-ui'
import { get, post } from './utils/http'
import * as filters from './filters/index'
import 'element-ui/lib/theme-chalk/index.css' // 默认主题
import './assets/css/icon.css'
Object.keys(filters).forEach(key => {
Vue.filter(key, filters[key])
})
| 管道符使用即可
