HTML | DOM Input Time readOnly Property - ❤️️ Online HTML tutorial

It means that a user can not modify or changes a content already present in a particular Element (However, a user can tab to it, highlight it, and copy the text from it) whereas a JavaScript can be used to change the read-only value and make the input field editable.

```
timeObject.readOnly
```

```
timeObject.readOnly = true|false
```

Property Values:

true: It defines that Time field is read only.
false: It defines that Time field is not read only. It is false by default.

Return Value: It returns a boolean value which represent the Time field is read only or not.
