当你将纯 JavaScript 对象作为其数据选项传递给 Vue 实例时,Vue 将遍历其所有属性并用 Object.defineProperty 将它们转换为 getter/setter。getter/setter 对用户是不可见的,但是在幕后,它们使 Vue 能够在访问或修改属性时执行依赖关系跟踪和更改通知。—— Vue.js 文档:响应式(https://vuejs.org/v2/guide/reactiv...

vue中计算属性之set和get computed计算属性中包含了set和get两个方法(回调函数) get回调函数: 当需要读取当前属性值时调用,根据相关的数据计算并返回当前属性的值 set回调函数:监视当前属性值发生改变时调用,更新相关的属性值 计算属性的结果会被缓存,除非依赖的响应式属性变化才会重新计算,否则就是多次调用,但只会...
