Create and Send Interactive Form Fields using JavaScript

After a user takes an action, I dynamically generate this form using JavaScript:

<form id="editBookForm" onsubmit="editBookData()">
   <input type="text" name="isbn" placeholder="ISBN"  required />
   <input type="text" name="book" placeholder="Book..."  required />
   <button class ="btn">Update!</button>
</form>

The function editBookData() is as follows:

function editBookData(data) {
    console.log(data)
   //Additional tasks here
}

I am seeking guidance on how to prevent the default submission behavior of the form and pass the form data so that it can be accessed within the editBookData() function.

Please provide solutions without using JQuery. Thank you in advance.

Answer №1

To prevent the form from reloading, you can utilize the preventDefault() method. Additionally, to retrieve the input text values of the form, you can make use of the querySelector method within your function.

Check out this Live Demo: (No jQuery)

function editBookData(e) {
  e.preventDefault() //prevents default behavior 
  //retrieve input values
  let isbn = document.querySelector('input[name="isbn"]').value
  let book = document.querySelector('input[name="book"]').value
  console.log(isbn, book)
  //Perform additional tasks with the obtained values
}

<form id="editBookForm" onsubmit="editBookData(event)">
  <input type="text" name="isbn" placeholder="ISBN" required />
  <input type="text" name="book" placeholder="Book..." required />
  <button class="btn">Update!</button>
</form>

Prevent form submission by using event.preventDefault() and dynamically generate a form using the FormData Web API.

function handleFormData(event) {
  event.preventDefault();
  let formDataElement = document.getElementById('formData');
  let formData = new FormData(formDataElement);
  for (data of formData.values()) {
    console.log(data);
  }
  // .... other actions to perform
}

<form id="formData" onsubmit="handleFormData(event)">
      <input type="text" name="user" placeholder="Username" required />
      <input type="email" name="email" placeholder="Email..." required />
      <button class="btn">Submit</button>
