This is just a simple chrome extension

the core code has like one line of actual code for Pick3 and Pick4 right now in fill.js and fillp4.js

I might make one for Jackpot games later.

You just goto chrome://extentions in your chrome browser turn on developer mode

click Load unpacked, the load the folder that contains the files, the when you click the Plug-in (puzzle icon near top right corner of chrome) it'll show up and if you click Populate PredPicks it'll show you 3 buttons that you can use (when you're on the Post Predictions page)

and load this folder it seems I can't attach files or folders but here it is the code to all the files (edit/cut/copy with text editor)

my-extension/
├── manifest.json

├── popup.html

├── popup.js

├── fill.js (pick3 code)

├── fillp4.js (pick4 code)

"manifest_version": 3,
"name": "Populate predPicks",
"version": "1.0",
"permissions": ["scripting", "activeTab"],
"action": {
"default_popup": "popup.html"
}
}

<button id="fillBtn2">Pick 4</button>
<button id="fillBtn3">TBA...</button>
<script src="popup.js"></script>
</body>
</html>

popup.js -----------------------------------------------------------------------------------------------------------------------------

document.getElementById("fillBtn").addEventListener("click", async () => {
const [tab] = await chrome.tabs.query({ active: true, currentWindow: true });

chrome.scripting.executeScript({
target: { tabId: tab.id },
files: ["fill.js"]
});
});

document.getElementById("fillBtn2").addEventListener("click", async () => {
const [tab] = await chrome.tabs.query({ active: true, currentWindow: true });

chrome.scripting.executeScript({
target: { tabId: tab.id },
files: ["fillp4.js"]
});
});

fill.js -----------------------------------------------------------------------------------------------------------------------------

textarea = document.getElementById("predPicks");
if (textarea) {
textarea.value += ("00"+Math.floor(Math.random()*100)).slice(-3)+"\n";
textarea.dispatchEvent(new Event('input')); // in case site uses input events
} else {
alert("Textarea with ID 'predPicks' not found.");
}

fillp4.js -----------------------------------------------------------------------------------------------------------------------------

textarea = document.getElementById("predPicks");
if (textarea) {
textarea.value += ("000"+Math.floor(Math.random()*1000)).slice(-4)+"\n";

}

This extension only populates numbers in the text area of the post predictions page.

It doesn't post predictions for you. You'll still need to do that yourself.

Anyone interested in seeing the third button (currently TBA... button) turn into a Jackpot game generator for "Post Predictions"?

extensions don't compile, they're just text files that the computer reads.
