Question

如果我尝试加入m.facebook.com，我想帮助了解如何转到Chrome的上一页

让我告诉你我的代码：

var host = "http://www.google.com";          // here you put the URL that you want to be redirected 



chrome.webRequest.onBeforeRequest.addListener(
    function(details) {
         return {redirectUrl: host + details.url.match(/^https?:\/\/[^\/]+([\S\s]*)/)[1]};              //where it says "host" you put the name of the var that you have set above to the URL that you want to be redirected


    },
    {
        urls: [
            "*://m.facebook.com/*"                  // here you put the URL that you want to block.
        ],
        types: ["main_frame", "sub_frame", "stylesheet", "script", "image", "object", "xmlhttprequest", "other"]
    },
    ["blocking"]
);

清单

{
    "name": "Facebook Notification Block",
    "description": "Block Notification",
    "version": "1.0",
    "manifest_version": 2,
    "background": {
        "scripts": [
            "background.js"
        ]
    },
    "permissions": [
            "webRequest",
            "*://facebook.com/*",
            "*://m.facebook.com/*",
            "*://www.facebook.com/*",
        "webRequestBlocking"
    ]
}

使用此代码我可以＆＃34;阻止＆＃34; m.facebook.com并重定向到＆＃34; www.google.com＆＃34;我已经安装了扩展程序，从我的Chrome浏览器。但我只想转到上一页。

UPDATE1：

像克里斯托弗建议我尝试这些代码

添加到清单权限＆＃34;历史＆＃34;

我做了像这样的background.js

var goBack = function() {
    window.history.back();
}

chrome.webRequest.onBeforeRequest.addListener(
    function(details) {
         return {goBack};               


    },
    {
        urls: [
            "*://m.facebook.com/*"                  // here you put the URL that you want to block.
        ],
        types: ["main_frame", "sub_frame", "stylesheet", "script", "image", "object", "xmlhttprequest", "other"]
    },
    ["blocking"]
);

但我无法弄清楚我的错误。

Answer 1

var goBack = function() {
    window.history.back();
}

这是你的意思吗？

Answer 2

您可以使用chrome.history API扩展来读取历史记录，从那里我猜您可以获得上一页。

history extension source

我可以推动＆＃34;返回＆＃34;用javascript打开铬的按钮
