Submitting POST Requests in JavaScript: A Form-Based Approach

To submit POST requests in JavaScript and navigate to a different page as if submitting a form, consider this solution:

/**
 * sends a request to the specified url from a form. this will change the window location.
 * @param {string} path the path to send the post request to
 * @param {object} params the parameters to add to the url
 * @param {string} [method=post] the method to use on the form
 */

function post(path, params, method='post') {
  // Create a form and add it to the DOM
  const form = document.createElement('form');
  form.method = method;
  form.action = path;
  document.body.appendChild(form);

  // Create hidden input fields for each parameter
  for (const key in params) {
    if (params.hasOwnProperty(key)) {
      const hiddenField = document.createElement('input');
      hiddenField.type = 'hidden';
      hiddenField.name = key;
      hiddenField.value = params[key];

      form.appendChild(hiddenField);
    }
  }

  // Submit the form
  form.submit();

  // Optionally, remove the form from the DOM
  document.body.removeChild(form);
}

// Example:
post('/contact/', {name: 'Johnny Bravo'});
