내 JavaScript 양식 제출에 확인 대화 상자를 어떻게 추가합니까?

<code class="js">function confirmFormSubmission() {
  if (confirm("Confirm submission?")) {
    // Form submission allowed
  } else {
    // Submission canceled
  }
}</code>

<code class="js">function confirmFormSubmission() {
  if (confirm("Are the fields filled out correctly?")) {
    document.form.submit(); // Submit the form
  } else {
    return false; // Cancel submission
  }
}</code>

<code class="html"><form onsubmit="return confirm('Confirm submission?');"></code>

<code class="js">function validateForm(form) {
  // Validation code goes here

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

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