我想知道如何禁用事件偵聽器“復(fù)制”我認(rèn)為它是這樣的：.js 文件：let btn = document.getElementById('btn');document.body.addEventListener('click', function(e) {  if (e.target.id === 'btn') {    e.stopPropagation();  }}, {  capture: false});提前致謝！清單.json：{  "name": "Test",  "version": "1.0",  "description": "Just testing!",  "manifest_version": 2,  "icons": {    "48": "images/icon_48.png",    "128": "images/icon_128.png"  },  "browser_action": {    "default_icon": "images/icon_16.png",    "default_popup": "popup.html"  }}
