Google chrome extension chrome扩展上下文菜单（用于链接）能否在弹出链接内容之前提取链接内容？

我想根据上下文链接的内容创建上下文菜单项

例如，我想为以“AAA”开头的链接显示“AAA”https://www.google.com和“BBB”表示以开头的链接https://twitter.com“

在后台脚本中尝试以下操作：

function onClickHandler(info, tab) {
    let tp = info.menuItemId;
    let url = info.linkUrl;
    switch (tp) {
        case 'AAA':
            alert('hi google user');
            break;
        case 'BBB':
            alert('hi Tweeter user');
            break;
    }
}

function handleInstalled(details) {
    var contextMenuItem = [
        {
            "id": "AAA",
            "title": "AAA",
            "contexts": ["link"],
            "targetUrlPatterns": ["https://*.google.com/*"]
        }, {
            "id": "BBB",
            "title": "BBB",
            "contexts": ["link"],
            "targetUrlPatterns": ["https://*.twitter.com/*"]
        }
    ];
    let cmi;
    for (let k = 0; k < contextMenuItem.length; k++) {
        cmi = contextMenuItem[k];
        chrome.contextMenus.create({
                "id": cmi.id,
                "title": cmi.title,
                "contexts": cmi.contexts,
                "enabled": true,
                "targetUrlPatterns": cmi.targetUrlPatterns
            }, () => {
                if (chrome.runtime.lastError) {}
                else {}
            })
    }
    chrome.contextMenus.onClicked.addListener(onClickHandler)
}

chrome.runtime.onInstalled.addListener(handleInstalled);

函数onClickHandler（信息，选项卡）{
设tp=info.menuItemId；
设url=info.linkUrl；
交换机（tp）{
案例“AAA”：
警报（“嗨谷歌用户”）；
打破
案例“BBB”：
警报（“hi Tweeter用户”）；
打破
}
}
已安装函数句柄（详细信息）{
var contextMenuItem=[
{
“id”：“AAA”，
“头衔”：“AAA”，
“上下文”：[“链接”]，
“targetUrlPatterns”：[“https://*.google.com/*”]
}, {
“id”：“BBB”，
“头衔”：“BBB”，
“上下文”：[“链接”]，
“targetUrlPatterns”：[“https://*.twitter.com/*”]

else{}
