HTML DOM Input Tel readOnly Property
The DOM Input tel readOnly property is used to set or return whether the tel field should be read-only or not. It means that a user cannot modify or changes the 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.
Syntax:
It is used to return the readOnly property.
telObject.readOnly
It is used to set the readOnly property.
telObject.readOnly = true|false
Property Values:
- true: It defines that the input tel field is read-only.
- false: It is the default value. It defines that the tel field is not read-only.
Return Value: It returns a boolean value that represents whether the tel field is read-only or not.
