To implement a loader after form validation using JavaScript, you can follow these steps:

  1. Create an HTML element for the loader. This can be a simple
1
<div id="loader"></div>


  1. Create a CSS class for the loader with appropriate styling and animation. For example:
1
2
3
4
#loader {
  /* specify loader's position, size, and styling */
  /* can include animation properties */
}


  1. Write JavaScript code to handle form validation and show/hide the loader.

// Get a reference to the form and loader element
const form = document.querySelector('form');
const loader = document.querySelector('#loader');

// Add an event listener on form submission
form.addEventListener('submit', (e) => {
  // Prevent the default form submission behavior
  e.preventDefault();

  // Perform form validation logic here
  
  // If form is valid
  if (valid) {
    // Show the loader
    loader.style.display = 'block';

    // Perform necessary processing or API call
    
    // After processing is done, hide the loader
    loader.style.display = 'none';
  }
});


  1. Customize the JavaScript code as per your specific validation logic and processing steps.


Note: The example provided shows a basic loader implementation after form validation. You can further enhance it by adding animation effects, handling errors, updating the UI with success messages or error messages, etc., based on your requirements.

This is a general implementation of a loader after form validation. You may need to modify it according to your specific validation logic and processing steps.
