vue封裝可復(fù)用組件confirm,并綁定在vue原型上的示例

 //暴露出去，別忘記掛載到vue的原型上 
 // => 在main.js里面先引入 import theConfirm from './components/confirm/confirm.js'
 // => 再掛載 Vue.prototype.$confirm = theConfirm;
 //在需要的地方直接用以下方法調(diào)用即可：
 // this.$confirm({
 //  type:'提示',

// (runtime-only or standalone) has been set in webpack.base.conf with an alias.

//這里就是對(duì)組件的綁定
