Vue中组件化编码的大致流程(初接触)、组件之间的参数传递(最基础的形式)、组件之间的配合完成一个需求
(1)、拆分静态组件:组件要按照功能点拆分,命名不要与html元素冲突。
(2)、实现动态组件:考虑好数据的存放位置,数据是一个组件在用,还是一些组件在用:
1)、一个组件在用:放在组件自身即可。
2)、 一些组件在用:放在他们共同的父组件上(状态提升)。
(3)、实现交互:从绑定事件开始。
(1)、父组件 ==> 子组件 通信
(2)、子组件 ==> 父组件 通信(要求父先给子一个函数)
使用v-model时要切记:v-model绑定的值不能是props传过来的值,因为props是不可以修改的
props传过来的若是对象类型的值,修改对象中的属性时Vue不会报错,但不推荐这样做。
