vue2进阶篇：vue-router之路由的params参数_vue router params

10.7路由的params参数

注意点1：
跳转路由并携带params参数，to的对象写法中，不能配置path参数，不然页面会没效果（就是点击完数据都没了），正确写法只能配置name属性，不能配置path属性


注意点2：两种写法
跳转路由并携带params参数，to的字符串写法

<router-link :to="`/home/message/detail/${m.id}/${m.title}`">{{m.title}}</router-link>
1

跳转路由并携带params参数，to的对象写法

<router-link :to="{
	 name:'xiangqing',
	 params:{
		id:m.id,
		title:m.title
	 }
}">
	{{m.title}}
</router-link>
