咨询：无需插件，通过URL或开发者工具实现网页定时刷新

Hey there! Nice use case—getting that employee schedule to auto-refresh on a big screen without plugins is totally achievable with a couple of browser-native hacks. Let me walk you through two solid methods:

This is perfect if you just need a one-off setup for the day:

• Open developer tools: Hit F12 or Ctrl+Shift+I (Windows/Linux) / Cmd+Opt+I (Mac) on your keyboard.
• Switch to the Console tab.
• Paste this JavaScript snippet, adjusting the interval to your preferred time (15 mins = 900000 ms, 30 mins = 1800000 ms):

// Adjust this value to set your refresh interval (milliseconds)
const refreshInterval = 900000; // 15 minutes
setInterval(() => {
  window.location.reload();
}, refreshInterval);

• Press Enter. The page will now auto-refresh at your chosen interval. Just keep the browser window open—this works until you close the tab or restart the browser.

If you want a reusable solution without opening dev tools every time, a bookmarklet is your best bet:

• Create a new bookmark: Right-click your browser's bookmarks bar and select "Add Page" (or similar, depending on your browser).
• For the Name, use something like "Auto-Refresh Schedule".
• For the URL, paste this minified JavaScript (tweak the interval value if needed):

javascript:(function(){const r=900000;setInterval(()=>{window.location.reload();},r);})();

• Save the bookmark. Now, whenever you load the schedule page, just click this bookmark to kick off auto-refreshing. No plugins required—this is just a tiny script that runs directly in your browser.

Quick Notes to Keep in Mind #

• Since this is a read-only display, reloading won't cause issues with form inputs or sessions (which would be a problem on interactive pages).
• Most browsers won't block auto-refresh if the tab is active—perfect for a dedicated big screen setup.
• To stop auto-refreshing, just close the tab or manually refresh the page (the interval resets when the page reloads).
