Definition and Usage
The disabled attribute is a boolean attribute.
When present, it specifies that the <input> element should be disabled.
A disabled input element is unusable and un-clickable.
The disabled attribute can be set to keep a user from using the <input> element until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript could remove the disabled value, and make the <input> element usable.
Tip: Disabled <input> elements in a form will not be submitted!
Browser Support
The numbers in the table specify the first browser version that fully supports the attribute.
