To set a checkbox as auto-checked using JavaScript, you can use the .checked property. Here’s an example:

JavaScript Code: 

// Select the checkbox element by its ID, class, or any valid selector
const checkbox = document.querySelector('#yourCheckboxId');

// Set the checkbox to be checked
checkbox.checked = true;

// Optionally log or perform further actions
console.log('Checkbox is now auto-checked.');

Example HTML: 

<form>
  <label>
    <input type="checkbox" id="yourCheckboxId">
    I agree to the terms and conditions
  </label>
</form>

Explanation:

  1. document.querySelector('#yourCheckboxId'): Finds the checkbox element. Replace #yourCheckboxId with the actual ID, class, or selector for your checkbox.
  2. checkbox.checked = true;: Sets the checked property to true, which checks the checkbox.

For Multiple Checkboxes:

If you need to auto-check multiple checkboxes:

const checkboxes = document.querySelectorAll('.yourCheckboxClass');
checkboxes.forEach(checkbox => {
  checkbox.checked = true;
});

This will check all checkboxes that match the .yourCheckboxClass selector. Let me know if you need further assistance!
