1608879 - Setting the value of an <input type="date" disabled> has no effect

Status: RESOLVED DUPLICATE of bug 1465979

(Core :: DOM: Core & HTML, defect)

Description

[Yannik]

Attachment: test.html

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:72.0) Gecko/20100101 Firefox/72.0

Steps to reproduce:

1. Open the HTML file attached to this ticket
2. Initialize the date field with a value
3. Make the field disabled or read-only using the provided button
4. Try the mutation button (change field value or clear using empty string/null)

Actual results:

• Using the set value buttons with an actual date sets the value of the disabled field
• The Set empty string / Set null button has no effect

Expected results:

• All mutation buttons should work the same, not matter the disabled/readonly state. At least though setting a new value and setting an empty value should behave the same.

Background:

The HTML 5.3 spec says about disabled :

A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.

So it states that only USER INTERACTION should be prevented, not script interaction. I could not find any hint, that clearing the field should be prevented.

Ah yes it looks like an exact duplicate. I am sorry... My Google-Fu is weak.
