本篇文章主要讲述vue-router(前端路由)使用的详细步骤
目录
1.npm安装(vue2安装vue-router@3/vue3安装vue-router@4)
2.main.js注册vue-router
3.创建router配置文件
4.在父组件中(使用了element组件侧导栏)
写入变换路由时页面改变加载的内容位置,使用组件(RouterView)
写入"编程式路由跳转的方式"(this.$router.push)
若进入就想让其显示哪个路由对应的页面内容
父组件完整代码示例:
5.App.vue中写入父组件
Demo动态演示
1.npm安装(vue2安装vue-router@3/vue3安装vue-router@4)
我这里以vue2创建的项目中实战为示例
npm i vue-router@3
2.main.js注册vue-router
import VueRouter from 'vue-router'
import router from './router/index';
Vue.use(VueRouter)
new Vue({
el:'#app',
render: h => h(App),
router:router
});
3.创建router配置文件
创建文件:在src目录下创建"router"文件夹,里面创建"index.js"
index.js里面配置代码如下:
import VueRouter from 'vue-router'
//引用自定义的组件
import ShouYe from '@/components/ShouYe'
import User_Center from '@/components/User_Center'
import user_management from '@/components/user_management'
import info_management from '@/components/info_management'
//抛出自定义声明的路由器
export default new VueRouter({
//给引用的自定义的组件添加名字,路径等属性
routes:[
{
name:'shouye1',
path:'/ShouYe',
component:ShouYe,
},
{
name:'usercenter1',
path:'/User_Center',
component:User_Center
},
{
name:'usermanagement1',
path:'/user_management',
component:user_management
},
{
name:'infomanagement1',
path:'/info_management',
component:info_management
}
]
})
4.在父组件中(使用了element组件侧导栏)
写入变换路由时页面改变加载的内容位置,使用组件(RouterView)
<RouterView style="margin-left: 100px;"></RouterView>
写入"编程式路由跳转的方式"(this.$router.push)
methods: {
// 跳转系统首页
shouye() {
this.$router.push({
name: "shouye1",
});
},
}
若进入就想让其显示哪个路由对应的页面内容
mounted(){
this.$router.push({
name: "shouye1",
});
},
父组件完整代码示例:
<template>
<div>
<div class="top">
<img style="margin-left: 70px;" src="../assets/Lielong.png" />
<div style="color: aliceblue;margin-left: 100px;margin-top: 40px;font-size: larger;">{{ Breadcrumb }}</div>
<el-button style="font-size: larger;margin-left: 1400px;" type="text" @click="open">退出系统</el-button>
</div>
<!-- 主体 -->
<div class="one">
<div>
<el-row >
<el-col :span="12" class="tac">
<el-menu default-active="1" class="box" @select="handselect" background-color="#545c64" text-color="#fff"
active-text-color="#ff0303">
<el-menu-item style="margin-top: 30px;" index="1" @click="shouye">
<i class="el-icon-setting"></i>
<span slot="title">系统首页</span>
</el-menu-item>
<el-menu-item index="2" @click="user_center">
<i class="el-icon-menu"></i>
<span slot="title">个人中心</span>
</el-menu-item>
<el-menu-item index="3" @click="user_management">
<i class="el-icon-document"></i>
<span slot="title">客户管理</span>
</el-menu-item>
<el-menu-item index="4" @click="info_management">
<i class="el-icon-setting"></i>
<span slot="title">信息管理</span>
</el-menu-item>
</el-menu>
</el-col>
</el-row>
</div>
<RouterView style="margin-left: 100px;"></RouterView>
</div>
<!-- 路由组件 -->
</div>
</template>
<script>
import { RouterView } from 'vue-router';
// import axios from 'axios'
export default {
props: {
msg: String
},
data() {
return {
tab: [
"系统首页",
"个人中心",
"客户管理",
"信息管理"
],
Breadcrumb: "系统首页",
};
},
mounted(){
this.$router.push({
name: "shouye1",
});
},
methods: {
handselect(res) {
console.log(res);
this.Breadcrumb = this.tab[res - 1];
},
// 退出系统
open() {
this.$confirm("此操作将退出登录, 是否继续?", "提示", {
confirmButtonText: "确定",
cancelButtonText: "取消",
type: "warning"
}).then(() => {
this.$message({
type: "success",
message: "退出成功!"
});
}).catch(() => {
this.$message({
type: "info",
message: "已取消退出"
});
});
},
// 跳转系统首页
shouye() {
this.$router.push({
name: "shouye1",
});
},
// 跳转个人中心
user_center() {
this.$router.push({
name: "usercenter1",
});
},
// 跳转客户管理
user_management() {
this.$router.push({
name: "usermanagement1",
});
},
// 跳转信息管理
info_management() {
this.$router.push({
name: "infomanagement1",
});
}
},
components: { RouterView }
}
</script>
<style scoped>
.one{
display: flex;
flex-direction: row;
}
.tac {
width: 200px;
}
.box {
height: 819px;
box-shadow: 0 5px 5px rgba(0, 0, 0, 0.5);
}
.top {
display: flex;
height: 100px;
background: #545c64;
box-shadow: 0 0 5px rgba(0, 0, 0, 0.5);
}
</style>
5.App.vue中写入父组件
<template>
<div id="app">
<Demo_D1 />
</div>
</template>
<script>
import Demo_D1 from './common/Demo_D1.vue'
export default {
components: {
Demo_D1
},
}
</script>
<style>
*{
padding: 0;
margin: 0;
}
#app {
font-family: Avenir, Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
}
</style>
