I've created an account to access Google's captcha service, but I'm having difficulty getting it to work properly. I have two main files: `index.html` and `form.php`. Here's what I've accomplished so far and where I need help:
1. I've successfully loaded the JavaScript API with my key in `index.html`.
2. I'm trying to set up a callback function to handle the response token, but I'm unsure where exactly to paste the code. Here's the snippet I have:
function onSubmit(token) {
document.getElementById("demo-form").submit();
}
My questions are: **In which part of `index.html` should I place this code? Also, do I need to change "demo-form" to something else?**
3. I've added the necessary attributes to my HTML button in `index.html`, so that part is done.

Also, don’t forget that your button should have `data-sitekey="your-site-key"` and `data-callback="onSubmit"` attributes for it to trigger the captcha properly. If you’ve added those already, you’re on the right track!
Hey! For the callback function, you usually want to place your script near the bottom of your `index.html`, just before the closing tag. This way, the DOM is fully loaded before it tries to execute. About the 'demo-form', you should replace it with the actual ID of your form element in `form.php`. Make sure your form has an ID attribute! So it should look something like this: `` where `yourFormId` is the ID you set.
