var app=new Vue({    el:‘#app‘,    data:{        a:2    },    beforeCreate:function(){        console.log("实例创建之前");    },    created:function(){        console.log("a is:"+this.a);        console.log("实例创建之后");    },    beforeMount:function(){        console.log("模板编译/挂载之前")    },    mounted:function(){        console.log("模板编译/挂载之后")    },    beforeupdated:function(){        console.log("实例更新之前")    },    updated:function(){        console.log("实例更新之后")    },    beforeDestory:function(){        console.log("组件销毁前调用")    },    destroyed:function(){        console.log("组件销毁后调用")    }})
