javascript - vue 全局组件为什么不能跟vue实例分开到不同的文件中？
问题描述
global.js文件:var app;app = new Vue({ el: '#app', data: {value: 'hello world', }});login.js
Vue.component(’login’, { template: ’<h1>login</h1>’})index.html
<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>Daemon</title> <script src='https://www.haobala.com/wenda/js/jquery-3.2.1.js' charset='UTF-8'></script> <script src='https://www.haobala.com/wenda/js/semantic.min.js' charset='UTF-8'></script> <script src='https://www.haobala.com/wenda/js/vue.js' charset='UTF-8'></script> <link rel='stylesheet' href='https://www.haobala.com/wenda/css/semantic.min.css'></head><body> <p id='app'><p class='ui container'> <p class='ui pider'></p> <p class='ui blue button'>{{value}} </p> <login></login></p> </p> <script src='https://www.haobala.com/wenda/js/global.js' charset='UTF-8'></script> <script src='https://www.haobala.com/wenda/js/login.js' charset='UTF-8'></script></body></html>
结果报错:[Vue warn]: Unknown custom element: <login> - did you register the component correctly? For recursive components, make sure to provide the 'name' option.(found in <Root>)
哪位大侠能为小白指点下？
问题解答
回答1：html中我做了一下修改，调整了js引入的顺序，因为需要在保证app根组件渲染的时候，其中用到的组件已经声明注册。

全局API系列都必须在实例化之前申明
