hook库中实现对window变量的proxy功能。 6 | 7 | # 二、Example 8 | 9 | ```js 10 | (async () => { 11 | 12 | const monitor = new WindowMonitor(); 13 | // 在window新增变量时会触发此处传入的Listener函数，Listener函数可以有多个 14 | await monitor.addWindowListener(key => { 15 | console.log(new Date(), key); 16 | }); 17 | // 启动监控器，其实就是个while循环不断的检查window上是否有新增变量 18 | await monitor.startWindowMonitor(); 19 | 20 | })(); 21 | 22 | const chars = "ABCDEFGHJKMNPQRSTWXYZ" 23 | 24 | function randomString(length) { 25 | length = length || 100; 26 | const charArray = []; 27 | for (let i = 0; i < length; i++) { 28 | charArray.push(chars.charAt(Math.floor(Math.random() * chars.length))); 29 | } 30 | return charArray.join(""); 31 | } 32 | 33 | function genGlobalVars() { 34 | window[randomString(40)] = randomString(6); 35 | setTimeout(genGlobalVars, Math.random() * 10) 36 | } 37 | 38 | setTimeout(() => { 39 | genGlobalVars(); 40 | }, Math.random() * 10) 41 | 42 | ``` 43 | 44 | # 三、原理 45 | 46 | 其实原理简单粗暴，就是每隔一段时间遍历window对其所有属性做一个快照，然后前后快照做diff，就能够找出来新增的变量或者删除的变量，对于第一个快照会认为是初始化，这样就能够把默认的属性给识别出来不触发新增事件。 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65
