Chrome扩展程序 - 意外的输入结束

Question

我正在尝试编写我的第一个chrome扩展程序，它通过url名称用于标签的简单自动排序，但是我在这段代码的末尾得到了“意外的输入结束”。它只是在我添加了onClicked的监听器后才出现。

chrome.browserAction.onClicked.addListener(function apllyOrder(tabs) {
    // gets reference array of sorted tabs
    reference = sortTabsUrl(tabs);
    console.log("Reference array loaded");
    // gets amount of pinned tabs to skip them
    pinned = tabsPinned(tabs);
    console.log("Pinned tabs identified");

    //iterates through reference array
    for(var i = 0, len = reference.length; i < len; i++){
    //iterates through tabs starting from first unpinned tabs
    for(var x = pinned, leng = tabs.length; x < leng; x++){
        //If the id matches AND reference index is different than current index than it moves the tab
        if(tabs[x].id == reference[i].id && x != (i +pinned)){
            // tabs is moved based on x(current index) + i(reference index)
            chrome.tabs.move(tabs[x].id, i + x)
        }
    }
}
});

我的清单文件是：

{
"manifest_version": 2,

"name": "Tab Organizer",
"description": "Auto Organizes Tabs",
"version": "1.0",

"background": {
    "scripts": ["tabOrganizer.js"],
    "persistent": false
},

"permissions": [
    "tabs",
    "<all_urls>"
],
"browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
}
}

我想我已经犯了一个愚蠢的错误，因为我是新来的，但提前感谢！
