之前一直看过vue.js官网api,但是很少实践,这里抽出时间谢了个入门级的demo,记录下一些知识点,防止后续踩坑,牵扯到的的知识点:vue、vue-cli、vue-router、webpack等。
首先看下实现的效果:
源码下载戳这里:源码
1、使用vue-cli脚手架创建项目
vue init webpack tll
备注:使用webpack模板创建名为tll的项目,这里会按照提示输入一些项目基本配置,比如项目名称、版本号、描述、作者、是否启用eslint校验等等,不知道咋填的直接回车即可
2、根据提示启动项目
tll项目创建完成后,vue会自动提示几个命令运行,直接依次执行:
cd tll
npm i
npm run dev
这样,一个自动配置好的vue项目便运行起来了,包含热更新、自动校验等,当然这些配置在build文件夹下的webpack.base.conf.js里面,找到loader、preloader加载器,直接注释掉相应功能也行。比如我写代码时,配置了eslint后,稍微有个空格啥的
多余eslint都会报错导致整个项目无法运行,这时直接注掉preloader中和eslint相关的即可。
3、编写组件
在src的components目录下,创建home.vue组件,详细代码:
<!--首页组件-->
<template>
<div class="home">
<h3>{{msg}}</h3>
</div>
</template> <script>
export default {
name:"home",
data(){
return {
msg:"这里是home视图"
}
}
}
</script> <style scoped>
h3{
background-color: #c5c5c5
}
</style>
同样地,创建user.vue组件:
<template>
<div>
<h3>{{msg}},获取到的参数是:{{$route.params.id}}</h3>
</div>
</template> <script>
export default{
name:"user",
data(){
return {
msg:"这里是user视图"
}
}
}
</script>
<style scoped>
h3{
background-color:gold
}
</style>
最后是product.vue组件:
<template>
<div class="product">
<h3>{{msg}},获取到的参数是:{{$route.params.id}}</h3>
</div>
</template> <script>
export default{
name:"product",
data(){
return {
msg:"这里是product视图"
}
}
}
</script>
<style scoped>
h3{
background-color:violet
}
</style>
4、修改app.vue,添加路由
<template>
<div id="app">
<nav class="top-menu">
<ul>
<!--遍历li,输出顶部工具栏-->
<li v-for="item in menulist">
<router-link :to="item.url">{{item.name}}</router-link>
</li>
</ul>
</nav>
<hr>
<div>
<router-view></router-view>
</div>
</div>
</template> <script>
export default {
name:"app",
data:function (){
return {
menulist:[
{"name":"首页",url:"/home"},
{"name":"用户",url:"/user/18"},
{"name":"产品",url:"/product/20"},
]
}
}
}
</script> <style>
#app { }
.top-menu ul, .top-menu li {
list-style: none;
}
.top-menu {
overflow: hidden;
}
.top-menu li {
float: left;
width: 100px;
}
</style>
5、创建详细路由配置
在src根目录下直接新建文件router.js作为我们的自定义路由,详细代码:
import VueRouter from "vue-router"
import Home from "./components/Home.vue"
import User from "./components/User.vue"
import Product from "./components/Product.vue" export default new VueRouter({
routes:[
{path:"/home",component:Home},
{path:"/user/:id",component:User},
{path:"/product/:id",component:Product}
]
})
这下便创建了三个导航的匹配路由,最后只要再做一件事即可,那便是让路由生效:将router挂载到vue实例上。
6、挂载路由组件到vue实例
修改main.js文件如下:
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App' // 引入路由组件、自定义路由组件
import VueRouter from "vue-router"
import router from "./router" //使用路由组件
Vue.use(VueRouter) /* eslint-disable no-new */
new Vue({
el: '#app',
template: '<App/>',
components: { App },
router:router
})
7、一个增删改查应用
效果如下:
