Question

SendMessage在新的Tab控制台上不起作用。

消息未到达刚刚打开的标签页。

控制台上没有显示任何内容。

popup.js

document.getElementById("preparaLista").addEventListener("click",handleClick);

    function handleClick(){
        chrome.tabs.create({ url: chrome.runtime.getURL("index.html") }, function(tab) {

            var handler = function(tabId, changeInfo) {
                if(tabId === tab.id && changeInfo.status === "complete"){
                chrome.tabs.onUpdated.removeListener(handler);
                chrome.tabs.sendMessage(tabId, {type: 'opa'});
                }
            };

            // in case we're faster than page load (usually):
            chrome.tabs.onUpdated.addListener(handler);
            // just in case we're too late with the listener:
            chrome.tabs.sendMessage(tab.id, {type: "action_example2"});

        });
    }

content.js

chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
    console.log(sender.tab ?
                "from a content script:" + sender.tab.url :
                "from the extension");

    console.log("received message from popup: "+request.type);

});

从弹出窗口打开带有本地index.html的新选项卡，然后向其发送消息
