HTML Input readonly Attribute

Definition and Usage

The readonly attribute specifies that the input field is read only (un-editable).
This attribute allows the user to highlight and copy the text inside the input field, but not change the value.
This attribute is often used together with a JavaScript to keep the user from editing a field before a specific task (lie clicking a button button or selecting checkbox) is completed.
This attribute is only used if the type attribute of the input element is set to "text" or "password".


<input readonly="readonly" />
