Edge Extension Store 上架需要 V3，chrome.tabs.executeScript 停用，使用 chrome.scripting.executeScript 代替，需要  tabId ！要这干啥？

获取当前 tabId 就没个 API 么？ 

chrome mands.onCommand.addListener(function (command) { console.log(command); if (command === 'capture_video') { let tab = await getCurrentTab(); console.log(tab[0].id); chrome.scripting.executeScript({ target: { tabId: tab[0].id }, files: ['video.js'] }); })(); } }); async function getCurrentTab() { let queryOptions = { active: true, lastFocusedWindow: true }; let tab = chrome.tabs.query(queryOptions); return tab; }

改好后报错：

Uncaught SyntaxError: await is only valid in async functions and the top level bodies of modules

用async匿名函数时候会出现的问题 - 杨强的个人小站 (idarc )

(async() => { ...... })();

改成这样可以了 

chrome mands.onCommand.addListener(function (command) { console.log(command); if (command === 'capture_video') { (async() => { let tab = await getCurrentTab(); console.log(tab[0].id); chrome.scripting.executeScript({ target: { tabId: tab[0].id }, files: ['video.js'] }); })(); } }); async function getCurrentTab() { let queryOptions = { active: true, lastFocusedWindow: true }; let tab = chrome.tabs.query(queryOptions); return tab; }

但是 popup.js 仍然无法获取 tabId。
