How To Submit Form Only Once After Multiple Clicking On Submit

Are you tired of your form being submitted multiple times just because users tend to click the submit button more than once? Fret not! In this article, we'll guide you through some simple yet effective ways to prevent multiple form submissions with just a bit of JavaScript magic.

Let's dive right into it. One common solution is to disable the submit button after the first click. This prevents users from clicking it again while the form is being processed. Here's a snippet of code you can use:

document.getElementById('submitBtn').addEventListener('click', function(event) {
  event.preventDefault();
  this.setAttribute('disabled', 'true');
  // Add additional code here to submit the form
});

In the above code, 'submitBtn' is the id of your submit button. When the button is clicked, it gets disabled, ensuring that it can't be clicked again until the form processing is complete.

Another approach is to display a loading spinner after the form is submitted. This not only indicates to users that something is happening but also prevents them from clicking the submit button multiple times. Here's how you can achieve this:

document.getElementById('submitBtn').addEventListener('click', function(event) {
  event.preventDefault();
  this.innerHTML = `<i class="fas fa-spinner fa-spin"></i> Loading...`;
  // Add additional code here to submit the form
});

In the above code, the submit button text is replaced with a spinner icon, indicating that the form is being processed.

Furthermore, you can also utilize session storage or cookies to keep track of whether the form has already been submitted. Here's an example using session storage:

document.getElementById('submitBtn').addEventListener('click', function(event) {
  event.preventDefault();
  if (!sessionStorage.getItem('formSubmitted')) {
    sessionStorage.setItem('formSubmitted', 'true');
    // Add additional code here to submit the form
  } else {
    alert('Form already submitted');
  }
});

In this code snippet, we check if the 'formSubmitted' flag is present in session storage. If it's not, we set it to 'true' after the form is submitted and prevent further submissions.

By implementing these techniques, you can ensure that your form is submitted only once, even if users click the submit button multiple times inadvertently. Remember, a better user experience leads to happier users!
