Question

这是popup.js：

function GetUrls()
{
var CurrentTabs = new Array();
chrome.tabs.query({}, function (tabs) {
    for (var i = 0; i < tabs.length; i++)
    {
        CurrentTabs[i] = tabs[i];
    }
    for (var i = 0; i < CurrentTabs.length; i++) 
    {
document.write("<b>" + CurrentTabs[i].title + "<button " +"</b>" + "<br/><a href='" + CurrentTabs[i].url + "' target='_blank'>" + CurrentTabs[i].url + "</a><br/><br/>");
   }
});
}
window.addEventListener("DOMContentLoaded", GetUrls());

function Save(){
    var title = document.title;
    var url = document.location.href;
 chrome.bookmarks.create({'parentId': bookmarkBar.id,
                         'document.title': 'Extension bookmarks'},
                        function(newFolder) {
  alert("added folder: " + newFolder.title);
}
window.addEventListener("DOMContentLoaded",Save());

我尝试将这个想法保存到书签，但没有任何反应。请问我该怎么做？

Answer 1

以下是保存书签的示例代码。打开弹出窗口时，代码首先在书签树中搜索标题为“Extension Bookmarks”的文件夹。如果找到，则会将其另存为destFolder以供将来使用，否则，会在“书签”栏下创建一个包含该标题的新文件夹，并设置为destFolder。单击该按钮后，Google书签会添加到“扩展书签”中。

的manifest.json

{
    "name": "Bookmarks Sample",
    "version": "1.0",
    "manifest_version": 2,
    "description": "Description",

    "browser_action": 
    {
       "default_popup": "popup.html"
    },

    "permissions": [
        "bookmarks",
        "tabs"
     ]
}

popup.html

<html>
    <head>
    </head>
    <body>
    </body>
    <footer>
        <script type="text/javascript" src="popup.js"></script>
    </footer>
</html>

    }
    var buttons = document.getElementsByTagName("button");
    for(var i=0; i<buttons.length; i++)
    {
        buttons[i].addEventListener('click',function(){addBookmark(this.getAttribute("data-url"), this.getAttribute("data-title"));})
    }
});
}
window.addEventListener("DOMContentLoaded", GetUrls());

var destFolder, bookmarkBar, finalMessage="";

chrome.bookmarks.getTree(findOrCreateDestinationFolder);

function findOrCreateDestinationFolder(rootNodes)

            return dest;
        }

    return null;

    else

    }
    alert(finalMessage);
