一、路由传递参数： 1、使用query传值： 2、使用params 传参： 地址上需要设置下第二个参数ID 二、嵌套路由children： ......
一、路由传递参数：
1、使用query传值：
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="x-ua-compatible" content="ie=edge" />
<title>路由</title>
<script src="./lib/vue.js"></script>
<!-- 1.安装vue-router路由模块 -->
<script src="./lib/vue-router.js"></script>
</head>
<body>
<div id="app">
<!-- 如果在路由中，使用 查询字符串，给路由传递参数，则不需要修改路由规则的path属性 -->
<router-link to="/login?id=10&name=zs">登录</router-link>
<router-link to="/register">注册</router-link>
<router-view></router-view>
</div>
<script>
var login = {
template:
"<h1>登录--{{ $route.query.id }}--{{ $route.query.name }}</h1>",
data() {
return {
msg: "123"
};
},
creadtd() {
//组件的生命周期钩子函数
// console.log(this.$route);
console.log(this.$route.query.id);
}
};
var register = {
template: "<h1>注册组件</h1>"
};
var routerobj = new vuerouter({
routes: [
{ path: "/login", component: login },
{ path: "/register", component: register }
]
});
var vm = new vue({
el: "#app",
data: {},
methods: {},
router: routerobj
});
</script>
</body>
</html>
2、使用params 传参：
地址上需要设置下第二个参数id
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="x-ua-compatible" content="ie=edge" />
<title>路由</title>
<script src="./lib/vue.js"></script>
<!-- 1.安装vue-router路由模块 -->
<script src="./lib/vue-router.js"></script>
</head>
<body>
<div id="app">
<!-- 如果在路由中，使用 查询字符串，给路由传递参数，则不需要修改路由规则的path属性 -->
<router-link to="/login/12">登录</router-link>
<router-link to="/register">注册</router-link>
<router-view></router-view>
</div>
<script>
var login = {
template: "<h1>登录--{{ $route.params.id }}</h1>",
data() {
return {
msg: "123"
};
},
creadtd() {
//组件的生命周期钩子函数
console.log(this.$route.params.id);
}
};
var register = {
template: "<h1>注册组件</h1>"
};
var routerobj = new vuerouter({
routes: [
// 除了上面的字母的不同外，这里还需要设置下添加的第二个参数id
{ path: "/login/:id", component: login },
{ path: "/register", component: register }
]
});
var vm = new vue({
el: "#app",
data: {},
methods: {},
router: routerobj
});
</script>
</body>
</html>
二、嵌套路由children：
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="x-ua-compatible" content="ie=edge" />
<title>路由</title>
<script src="./lib/vue.js"></script>
<!-- 1.安装vue-router路由模块 -->
<script src="./lib/vue-router.js"></script>
</head>
<body>
<div id="app">
<router-link to="/account">account</router-link>
<router-view></router-view>
</div>
<template id="tmp1">
<div>
<h1>这是account组件</h1>
<router-link to="/account/login">登录</router-link>
<router-link to="/account/register">注册</router-link>
<router-view></router-view>
</div>
</template>
<script>
var account = {
template: "#tmp1"
};
var login = {
template: "<h3>登录组件</h3>"
};
var register = {
template: "<h3>注册组件</h3>"
};
var router = new vuerouter({
routes: [
{
path: "/account",
component: account,
// 使用children 属性，实现子路由，同时子路由的path前面，不要带/，
// 否则永远以根路径开始请求，这样不方便我们用户去理解url地址
children: [
{
path: "login",
component: login
},
{
path: "register",
component: register
}
]
}
]
});
var vm = new vue({
el: "#app",
data: {},
methods: {},
router
});
</script>
</body>
</html>
