- jQuery.proxy
- ES6的proxy
- DOM事件代理
举个例子:
let start = {name: 'xxx',age: 18,phone: 12212212122}let agent = new Proxy(stat, {get: function(target, key) {if (key === 'phone') {return 'anent_phone: 13313313133'}if (key === 'price') {return 120000}return target[key]}set: function(target, key, value) {// 自定义逻辑来设置value}})
