如何通过浏览器控制台加速第三方网站的setTimeout倒计时器？

Alright, let's tackle this problem directly. Since you can't edit the site's source code, we'll override the existing timer logic using your browser's JavaScript console. Here's exactly how to do it:

Step 1: Understand the Original Timer Logic #

The site uses two key components for the timer:

• A countdown plugin that displays the minutes/seconds timer (set to 3600 seconds = 1 hour)
• A setTimeout that triggers RefreshPageAfterFreePlayTimerEnds() after 1 hour to reset the button

We need to replace both with our desired 20 or 30-minute duration.

Step 2: Run This Code in Your Browser Console #

First, open your browser's developer tools (press F12 or Ctrl+Shift+I), switch to the Console tab, then paste the code below. Adjust the duration by changing the newWaitSeconds value:

// Save the original refresh function so we can still use it later
const originalRefresh = window.RefreshPageAfterFreePlayTimerEnds;

// Clear ALL existing timeouts (the original 1-hour timeout has no variable reference, so this is the safest way)
let timerId = setTimeout(() => {}, 0);
while (timerId--) {
    clearTimeout(timerId);
}

// Destroy the original countdown timer instance
$('#time_remaining').countdown('destroy');

// Set your desired wait time in seconds: 20 mins = 1200, 30 mins = 1800
const newWaitSeconds = 1200; 

// Initialize a new countdown with your custom duration
$('#time_remaining').countdown({
    until: +newWaitSeconds,
    format: 'MS', // Keep the minutes/seconds display format
    onExpiry: function() {
        // Trigger the original refresh function when our timer ends
        originalRefresh();
    }
});

How It Works #

• Clearing Timeouts: The original 1-hour timeout isn't stored in a variable, so we loop through all possible timer IDs to clear it—this ensures it won't fire later and interfere with our custom timer.
• Replacing the Countdown: We destroy the old countdown instance and create a new one with your chosen duration (1200 seconds for 20 mins, 1800 for 30 mins).
• Preserving Functionality: We save and reuse the original RefreshPageAfterFreePlayTimerEnds() function so the page behaves exactly as it should when the timer finishes.

Notes #

• This only applies to your current browser session—if you refresh the page, you'll need to run the code again after clicking "Roll".
• Make sure to run this code right after the original timer starts (after clicking "Roll").
