将axios挂载到vue的原型上,那么在各个组件中都能使用,因为面向对象
下载axios
npm install axios
在vue中的使用
main.js中:
import Axios fomr ‘axios‘
Vue.prototype.$https = Axios
下载element-ui
npm install element-ui -S
在Vue中引入element-ui
在main.js中写入以下内容:
import Vue from ‘vue‘;
import ElementUI from ‘element-ui‘;
import ‘element-ui/lib/theme-chalk/index.css‘;//样式文件需要单独引入
import App from ‘./App.vue‘;
Vue.use(ElementUI);
new Vue({
el: ‘#app‘,
render: h =>(App)
});
