javascript - 无法使用 Chrome 控制台加载页面

Question

页面无法使用 Chrome 控制台加载，当代码执行完毕后，将加载最后一页

我希望看到页面在代码执行时加载。

function pause(milliseconds) {
    dt = new Date();
    while ((new Date()) - dt <= milliseconds) { }
}

console.error ('Page 1');

window.location.href = "example.com/?page=2;
pause (1000);
console.error ('Page 2');
pause (1000);

window.location.href = "example.com/?page=3;
pause (1000);
console.error ('Page 3');
pause (1000);

我想从第 1 页开始打开开发工具粘贴代码，让代码带我到第 2 页查看一秒钟，然后到第 3 页，依此类推几百页。

正如上面的评论所述，不可能在开发者控制台中运行脚本并让它在您访问多个页面时运行。但是，还有其他方法可以做到这一点。

我在这里向您展示的是使用 TamperMonkey Chrome 扩展程序。您可以将其添加到浏览器中，并添加以下脚本:

// ==UserScript==
// @name         URL looper
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  Loop through an Array of URLs
// @match        *://*/*
// @grant unsafeWindow
// @grant GM_setValue
// @grant GM_getValue
// ==/UserScript==

(function() {
    'use strict';

    const urls = [
        "https://stackoverflow.com/questions/tagged/javascript?page=1",
        "https://stackoverflow.com/questions/tagged/javascript?page=2",
        "https://stackoverflow.com/questions/tagged/javascript?page=3",
        "https://stackoverflow.com/questions/tagged/javascript?page=4",
        "https://stackoverflow.com/questions/tagged/javascript?page=5",
        "https://stackoverflow.com/questions/tagged/javascript?page=6"
    ];

    const delay = 1000;
    let timer;

    // Declare a global function which you can use in your console.
    // `unsafeWindow` is a way of accessing the page's `window` object from TamperMonkey
    unsafeWindow.MyLoop = {
        start: function() {
           // Set a global variable that will persist between page loads
           // and between multiple site domains
           GM_setValue('loopIsRunning', true);
           location.href = urls[0];
        },
        stop: function() {
           GM_setValue('loopIsRunning', false);
           clearTimeout(timer);
        }
    };

    if (GM_getValue('loopIsRunning')) {
        const currentIndex = urls.indexOf(location.href);
        if (currentIndex > -1 && currentIndex < urls.length - 1) {
            timer = setTimeout(function() {
                location.href = urls[currentIndex + 1];
            }, delay);
        } else if (currentIndex >= urls.length - 1) {
            unsafeWindow.MyLoop.stop();
        }
    }
})();

保存它，加载任何页面，打开控制台，然后您现在可以使用以下方法:

MyLoop.start();
MyLoop.stop();
