Vue 编程式路由导航的实现示例

/ /$router的两个api
this.$router.push({
	name : 'xiangqing',
	params :{
		id :xxx,
		title :xXX
	}
})
this.$router.replace({
	name : "xiangqing',
	params :{
		id : xxX,
		title :xXX
	}
})
this.$router.forward()//前进
this.$router.back()//后退
this.$router.Go()//可前进也可后退

<template>
  <div class="col-xs-offset-2 col-xs-8">
    <div class="page-header">
      <h2>Vue Router Demo</h2>
      <button @click="back">后退</button>
      <button @click="forward">前进</button>
      <button @click="test">测试一下 go</button>
    </div>
  </div>

    test(){
      this.$router.go(-3)
    }
  }
}
</script>

                <!--跳转路由并携带params参数，to的对象写法-->
        ......
        <button @click="pushShow(m)">push查看</button>
        <button @click="replaceShow(m)">replace查看</button>
