Confirm or Cancel Submission for Forms in JavaScript

Problem:
How to display a confirmation dialog box when submitting a form, with options to proceed or cancel?

Solution:

JavaScript's built-in confirm function can be used directly within the form's onsubmit event handler to achieve this functionality.

Implementation Options:

• Inline Confirmation:

<code class="html"><form onsubmit="return confirm('Do you want to submit the form?');"></code>

This inline confirmation will directly prompt the user for confirmation.

• External Function with Validation:

<code class="html"><form onsubmit="return validateForm();"></code>

<code class="javascript">function validateForm() {
  // Perform form validation here.

  if (!isValid) {
    alert('Please correct errors in the form!');
    return false;
  } else {
    return confirm('Do you want to submit the form?');
  }
}</code>

This method allows for additional validation checks before displaying the confirmation dialog box.
