Vue的优缺点

由 戏子无情 提交于 2021-02-04 23:00:28
使用vue.js做开发快两年了，对vue的优缺点有一点自己的见解，跟大神比不了，但是面试基本够用 　　vue在国内能被广泛使用的首要原因是它是基于mvvm框架做开发的，mvvm是前端开发中一种很有影响力的模式，在mvvm中，m代表model 即模型，model中集中粗出变量以及变量的值，v代表view 即视图，集中存储html和css，vm是二者名字的结合，viewmodel，我猜测这样命名应该是找不到合适的名字替代了~~，很多人沿用mvc的controller对mvvm的vm进行中文命名，mvc也是控制器，mvvm也是控制器，说起vm可老厉害了，厉害在哪呢，又是做什么的呢，vm是衔接同步view和model的数据交互控制器，源代码中的什么数据劫持，订阅者-发布者，这么复杂的定义，就留给大神和vue项目组研究吧，我们不要没研究透，反而越来越糊涂，vue有量大系统，第一，通知系统，第二，虚拟dom树，vue对象创建后，会自动引入data对象，data就是模型数据，data中的每一个变量都会自动添加两个访问器属性_set()和_get(),调用变量实际上是调用的访问器属性，当数据发生变化后，就会调用访问器属性，调用访问器属性就会触发通知系统，vm获得通知后就对虚拟dom树进行遍历，并修改需要修改的数据，然后同步到view中，这就是mvvm或者说vue事项双向绑定的原理
