vue.js怎么进行页面跳转？

<!-- 直接跳转 -->
<router-link to='/testDemo'>
 <button>点击跳转2</button>
</router-link>
 
<!-- 带参数跳转 -->
<router-link :to="{path:'testDemo',query:{setid:123456}}">
 <button>点击跳转1</button>
</router-link>
 
<router-link :to="{name:'testDemo',params:{setid:1111222}}">
 <button>点击跳转3</button>
</router-link>

<template>
 <p id='test'>
 <button @click='goTo()'>点击跳转4</button>
 </p>
</template>
<script>
 export default{
 name:'test',
 methods:{
 goTo(){
 //直接跳转
 this.$router.push('/testDemo');
 
 //带参数跳转
 this.$router.push({path:'/testDemo',query:{setid:123456}});
 this.$router.push({name:'testDemo',params:{setid:111222}});
 }
 }
 }
</script>

<p id="app">
			<p v-show="isShow">微风轻轻的吹来，带来了一丝丝凉意</p>
			<p>
				<button type="button" v-on:click="show(1)">显示</button>
				<button type="button" v-on:click="show(0)">隐藏</button>
			</p>
		</p>
		
		var vm = new Vue({
			el: '#app',
			data: {
				isShow:true
			},
			methods:{
				show:function(type){
					if(type){
						this.isShow = true;
					}else{
						this.isShow = false;
					}
				}
			}
		})
