从chrome.contextMenus.onClicked侦听器中获取当前URL

Question

我正在创建我的第一个Chrome扩展程序,我需要一些帮助.我认为一切正常,除了我无法获得标签的当前URL.

var menu = chrome.contextMenus.create({
    "title": "extension",
    "contexts": ["all"]
  });

chrome.tabs.query({'active': true, 'lastFocusedWindow': true}, function (tabs) {
        var siteUrl = tabs[0].url;
});

chrome.contextMenus.onClicked.addListener(function(activeTab)
{

    chrome.tabs.query({'active': true, 'lastFocusedWindow': true}, function (tabs) {
        var siteUrl = tabs[0].url;
    });

    var finalUrl = "http://example.com/";

    finalUrl += encodeURI(siteUrl);

    // Open the page up.
    chrome.tabs.create(
        {
            "url" : finalUrl
        }
    );
});

谁能帮帮我吗？谢谢.

编辑:

谢谢您的回复.我通过移动工作

var finalUrl = "http://example.com/";

    finalUrl += encodeURI(siteUrl);

    // Open the page up.
    chrome.tabs.create(
        {
            "url" : finalUrl
        }

内

chrome.tabs.query({'active': true, 'lastFocusedWindow': true}, function (tabs) {
        var siteUrl = tabs[0].url;
    });

Answer 1

chrome.tabs.getCurrent(function(tab){
    alert(tab.url);
});

或者,如果您在内容脚本中,

alert(document.location.href);

Answer 2

您需要的信息已经在onClicked监听器的回调中提供给您.

chrome.contextMenus.onClicked.addListener(function(info, tab) {
    // The URL of the tab (if any)
    var tabURL = tab && tab.url;

    // The URL of the page (if the menu wasn't triggered in a frame)
    var pageURL = info.pageUrl;

    // The URL of the frame (if the menu was triggered in a frame)
    var frameURL = info.frameUrl;

例如,你可以达到你想要的效果:

manifest.json的:

{
    "manifest_version": 2,
    "name":    "Test Extension",
    "version": "0.0",

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

    "permissions": ["contextMenus"]
}

background.js:

var baseURL = 'http://example.com/';

chrome.contextMenus.create({
    id: 'myMenu',   // <-- event-pages require an ID
    title: 'Do cool stuff',
    contexts: ['all']
}, function () {
    /* It is always a good idea to look for errors */
    if (chrome.runtime.lastError) {
        alert('ERROR: ' + chrome.runtime.lastError.message);
    }
});

chrome.contextMenus.onClicked.addListener(function(info, tab) {
    /* Check which context-menu was triggered */
    if (info.menuItemId === 'myMenu') {
        /* Get the URL of the frame or (if none) the page */
        var currentURL = info.frameUrl || info.pageUrl;

        /* Open a new tab */
        chrome.tabs.create({
            url: baseURL + encodeURI(currentURL)
        });
    }
});

如果您使用的是内容脚本,则可以使用

document.location.href

document.location 是Object,可以在URL中提供一组有用的块

• document.location.host返回域名ex:" http://www.google.com/ "
• document.location.path 返回域名后的部分
• document.location.hash 在URL中的#符号后面返回任何内容
