滚动到元素

ele.scrollIntoView({

    target.dispatchEvent(keyEventDown);
    target.dispatchEvent(keyEventUp);

    await sleep(interval + Math.random() * 30);
  }

  target.blur();
}

监听

window.addEventListener("customer", function (event) {
    });

发起

window.dispatchEvent(new CustomEvent("customer", {}));

查询tabs

function queryTabs(queryOptions) {
    return new Promise((resolve, reject) => {
        chrome.tabs.query(queryOptions, (result) => {
            if (chrome.runtime.lastError) {
                reject(chrome.runtime.lastError);
            } else {
                resolve(result);
            }
        });
    });
}

后台和内容脚本通信

接收方

chrome.runtime.onMessage.addListener( (request, sender, sendResponse) =>{
        console.log(`receive message: `, request);
        
        sendResponse({msg: 'msg'}); 
    //表示异步操作，不会立刻关闭消息接收
    return true; 

发送方

chrome.runtime.sendMessage({type: "query"}, (res) => {
        console.log("返回结果 ", res);
    });

发送方

postMessage({type: 'NOTIFY', msg: 'msg'}, '*')  //

接收方

window.onmessage = (e) => {
  console.log("收到消息");
  let {  type , msg} = e.data;
  switch (type) {
    case "NOTIFY":

      break;
  }
};
