过滤器:
全局
Vue.filter('过滤器的名字',function(data){ return })
{{num|过滤器的名字}}
<p>{{number}}</p>
局部
new Vue({
filters:{
过滤器的名字:function(data){
}
},
computed:{
number:function(){
}
}
})
计算属性:用来处理复杂逻辑操作 后期更容易维护
组件(component):组件化开发 组件可以扩展 HTML 元素,封装可重用的代码。
全局组件
局部组件
注:
组件名不可以使用已经存在的html元素
组件中的data数据是一个函数,并且要有一个返回值
