This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The show()
method of the 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 <dialog>
containing a form via the show()
method. From there you can click the Cancel button to close the dialog (via the 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); }); })(); </script>
