51工具盒子要是生活送了你一个柠檬，那你应该再要点盐与龙蛇兰。
首先在src下面建个utils包，创建个index.js
然后写上我们的全局函数
|---------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | hljs javascript //获取当前传入参数类型 export function getObjType(obj) { var toString = Object.prototype.toString var map = { '[object Boolean]': 'boolean', '[object Number]': 'number', '[object String]': 'string', '[object Function]': 'function', '[object Array]': 'array', '[object Date]': 'date', '[object RegExp]': 'regExp', '[object Undefined]': 'undefined', '[object Null]': 'null', '[object Object]': 'object' } if (obj instanceof Element) { return 'element' } return map[toString.call(obj)] } export default { getObjType } |
然后在main.js中引用并挂载全局
|------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | hljs javascript import Vue from 'vue' import App from './App.vue' import router from '@/router' import ElementUI from 'element-ui' import 'element-ui/lib/theme-chalk/index.css' import utils from '@/utils' Vue.use(ElementUI) Vue.config.productionTip = false //挂载全局 Vue.prototype.$utils = utils new Vue({ router, render: h => h(App), }).$mount('#app') |
最后就可以使用了
