vue組件的注冊
1.通過components方式注冊
2.通過router方式注冊(兩者可以並行存在).
3.如果是render+router方式, 那么router只能寫在render的組件template里.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="app">
<app01></app01>
<router-link to="/app001">/app001</router-link>
<router-link to="/app002">/app002</router-link>
<router-view></router-view>
</div>
<template id="app01">
<div>
<p>app01</p>
</div>
</template>
<template id="app001">
<div>app001</div>
</template>
<template id="app002">
<div>app002</div>
</template>
<script src="node_modules/vue/dist/vue.js"></script>
<script src="node_modules/vue-router/dist/vue-router.js"></script>
<script>
let app01 = {
name:'app01',
template: "#app01",
};
let app001 = {
name:'app001',
template: "#app001",
};
let app002 = {
name:'app002',
template: "#app002",
};
let routes = [
{path: '/app001', component: app001},
{path: '/app002', component: app002},
];
let router = new VueRouter({routes});
let vm = new Vue({
el: "#app",
components: {
app01
},
router
})
</script>
</body>
</html>
router方式靈活,可以作為components注冊組件的子組件存在
作為誰的子, 取決於router-link和router-view寫在誰下了.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="app">
<app01></app01>
</div>
<template id="app01">
<div>
<p>app01</p>
<router-link to="/app001">/app001</router-link>
<router-link to="/app002">/app002</router-link>
<router-view></router-view>
</div>
</template>
<template id="app001">
<div>app001</div>
</template>
<template id="app002">
<div>app002</div>
</template>
<script src="node_modules/vue/dist/vue.js"></script>
<script src="node_modules/vue-router/dist/vue-router.js"></script>
<script>
let app01 = {
template: "#app01",
};
let app001 = {
template: "#app001",
};
let app002 = {
template: "#app002",
};
let routes = [
{path: '/app001', component: app001},
{path: '/app002', component: app002},
];
let router = new VueRouter({routes});
let vm = new Vue({
el: "#app",
components: {
app01
},
router
})
</script>
</body>
</html>
render方式注冊組件
上面這個鏈接里說了: render+router
方法1:
render: c => c(app01)作用:
0,注冊組件
1.生成標簽
2.自動插入標簽
特點: 會覆蓋div.app下的內容
方法2:
render: c => c('app01')作用:
1.生成標簽
2.自動插入標簽
特點: 會覆蓋div.app下內容
document的的創建標簽方法
方法3: template
template: '
1,生成標簽
2,插入標簽
特點: 會覆蓋app下內容
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="app">
<h1>test</h1>
</div>
<template id="app01">
<div>
<p>app01</p>
</div>
</template>
<script src="node_modules/vue/dist/vue.js"></script>
<script>
let app01 = {
name: 'app01',
template: "#app01",
};
let vm = new Vue({
el: "#app",
template: '<app01/>',
components: {
app01
}
})
</script>
</body>
</html>
小結:
| render: c => c('app01') | template: '
|
|---|---|
| 1.生成標簽 | 1.生成標簽 |
| 2.插入標簽 | 2.插入標簽 |
| 覆蓋app下的內容 | 覆蓋app下的內容 |
| 配合runtime用 | 配合vue.js用 |
| 局部組件 | 全局組件 |
|---|---|
| 1.創建 | 1,創建 |
| 2.注冊 | - |
| 3.使用 | 3,使用 |
第二欄是 template: '<app01/>'
webpack: 使用render+runtime-only方式
- 方法1
new Vue({
el: '#app',
render: creatElment => creatElment(App),
});
- 方法2
通過render渲染一個元素, 然后把 App 當組件來用
new Vue({
el: '#app',
render: c => c('App'),
components: {
App
}
});
注意: 這種情況下, App 組件並不是根組件
webpack: 使用vue.js
- 方法3:
<div id="app">
<App></App>
</div>
import Vue from '../node_modules/vue/dist/vue.js'
import App from "./App.vue";
new Vue({
el: '#app',
components: {
App
}
});
- 方法4：
import Vue from '../node_modules/vue/dist/vue.js'
import App from './App.vue'
new Vue({
el: '#app',
template: '<App/>',
components: {
App
}
});
webpack: vue-cli使用的方式
vue-cli默認使用的是../node_modules/vue/dist/vue.js,而非runtime.
import Vue from '../node_modules/vue/dist/vue.js'
import App from './App.vue'
import login from './components/login.vue';
import register from './components/register.vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);
let routes = [
{path: '/login', component: login},
{path: '/register', component: register},
];
let router = new VueRouter({routes});
new Vue({
el: '#app',
template: '<App/>',
components: {App},
router
});
- 將login和register直接導入App.vue
- 將login和register先導入account.vue, 在將account.vue導入App.vue/
router方式導入
