{{ APIRef("HTML DOM") }} {{ SeeCompatTable() }}

+ +

The show() method of the {{domxref("HTMLDialogElement")}} interface displays the dialog modelessly, i.e. still allowing interaction with content outside of the dialog.

+ +

Syntax

+ +
dialogInstance.show();
+ +

Parameters

+ +

None.

+ +

Return value

+ +

Void.

+ +

Examples

+ +

The following example shows a simple button that, when clicked, opens a {{htmlelement("dialog")}} containing a form via the show() method. From there you can click the Cancel button to close the dialog (via the {{domxref("HTMLDialogElement.close()")}} method), or submit the form via the submit button.

+ +
  <!-- Simple pop-up dialog box, containing a form -->
+  <dialog id="favDialog">
+    <form method="dialog">
+      <section>
+        <p><label for="favAnimal">Favorite animal:</label>
+        <select id="favAnimal" name="favAnimal">
+          <option></option>
+          <option>Brine shrimp</option>
+          <option>Red panda</option>
+          <option>Spider monkey</option>
+        </select></p>
+      </section>
+      <menu>
+        <button id="cancel" type="reset">Cancel</button>
+        <button type="submit">Confirm</button>
+      </menu>
+    </form>
+  </dialog>
+
+  <menu>
+    <button id="updateDetails">Update details</button>
+  </menu>
+
+  <script>
+    (function() {
+      var updateButton = document.getElementById('updateDetails');
+      var cancelButton = document.getElementById('cancel');
+      var dialog = document.getElementById('favDialog');
+      dialog.returnValue = 'favAnimal';
+
+      function openCheck(dialog) {
+        if(dialog.open) {
+          console.log('Dialog open');
+        } else {
+          console.log('Dialog closed');
+        }
+      }
+
+      // Update button opens a modal dialog
+      updateButton.addEventListener('click', function() {
+        dialog.showModal();
+        openCheck(dialog);
+      });
+
+      // Form cancel button closes the dialog box
+      cancelButton.addEventListener('click', function() {
+        dialog.close('animalNotChosen');
+        openCheck(dialog);
+      });
+
