The DOM Input URL readOnly Property is used to set or return whether a URL Field should be read-only or not. It means that a user can not 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.
urlObject.readOnly
- It is used to Set the readOnly property.
urlObject.readOnly = true|false
Property Values:
- true: It defines that url field is read only.
- false: It is the default value. It defines that url field is not read only.
Return Value: It returns a boolean value which represent the URL field is read only or not.
