This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The returnValue
property of the HTMLDialogElement
interface gets or sets the return value for the <dialog>
, usually to indicate which button the user pressed to close it.
Syntax
dialogInstance.returnValue = 'myReturnValue'; var myReturnValue = dialogInstance.returnValue;
Value
A DOMString
representing the returnValue
of the dialog.
Examples
The following example displays a button to open a <dialog>
containing a form via the showModal()
method. From there, either button will close the dialog.
<!-- Simple pop-up dialog box containing a form --> <dialog id="favDialog"> <form method="dialog"> <p><label>Favorite animal: <select name="favAnimal" required> <option></option> <option>Brine shrimp</option> <option>Red panda</option> <option>Spider monkey</option> </select> </label></p> <menu> <button>Cancel</button> <button>Confirm</button> </menu> </form> </dialog> <menu> <button id="updateDetails">Update details</button> </menu> <script> (function() { var updateButton = document.getElementById('updateDetails'); var dialog = document.getElementById('favDialog'); dialog.returnValue = 'favAnimal'; function openCheck(dialog) { if (dialog.open) { console.log('Dialog open'); } else { console.log('Dialog closed'); } } function handleUserInput(returnValue) { if (returnValue === 'Cancel' || returnValue == null) { // User canceled the dialog, do nothing } else if (returnValue === 'Confirm') { // User chose a favorite animal, do something with it } } // โUpdate detailsโ button opens the <dialog> modally updateButton.addEventListener('click', function() { dialog.showModal(); openCheck(dialog); handleUserInput(dialog.returnValue); }); })(); </script>
Note: You can find this example on GitHub as htmldialogelement-basic (see it live also).
