                    this.newPerson = {name: \'\', age: 0, sex: \'Male\'}
                },
                /*这种写法也成 
                deletePerson: function(person){
                    this.people.splice(this.people.indexOf(person),1);
                } */
                deletePerson: function(index){
                    this.people.splice(index,1);
                }
            }
        })
    </script>
</html>

注意下遍历的写法哦，删除函数两种写法都行。创建函数一定要重置下对象，不然添加的都是同一行。

遍历：

  用如下的方法获得遍历的下标

 <tr v-for="(person,index) in people">
如果纯数字遍历就更简单了，‘基础一’举例了，

<div id="div1">
    <div v-for="i in 10">
     {{ i }}
    </div>
</div>
