路由懒加载:
const routes = [
进页面就全部加载:
{
path: '/',
name: 'Home',
component: Home
},
路由懒加载:
{
path: '/about',
name: 'About',
// route level code-splitting
// this generates a separate chunk (about.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
}
]

vue中组件间传值常⽤的⼏种⽅式(上)
⽗⼦组件传值
props / $emit
⼦组件中通过定义props接收⽗组件中通过v-bind绑定的数据
⽗组件中通过监听⼦组件中$emit的⾃定义事件接收数据
$parent / children
⼦组件中通过this.$parent这个对象获取⽗组件中的数据
⽗组件中通过this.$children这个数组获取⼦组件中的数据
$ref
⽗组件中定义⼦组件中的ref属性后,通过this.$refs.定义的属性名获取⼦组件数据
父传子:






第三种 ref

需求app.vue 传给child.vue
child.vue
mounted() {
console.log(this.$parent.baba);
//监听app发送过来的
bus.$on("sendChild", val => {
// console.log(val);
this.appSend = val;
});
}
app.vue
<button @click="passGetChild">app传给child</button>
methods: {
passGetChild() {
//发射
bus.$emit('sendChild','i come from app')
}
},
孙组件传值
app.vue 传给 child.vue
