    • Controls   
       
      1. Control types
       
       
      
    • The FORM element
  • Disabled and read-only controls
  • Disabled controls
  • Read-only controls
  • Form submission
  • controls (checkboxes, radio buttons, menus, etc.
  • A control's "control name" is given by its  name attribute. The scope of the name attribute for a control within a FORM element is the FORM element.
  • Disabled and read-only controls
  • In contexts where user input is either undesirable or irrelevant, it is important to be able to disable a control or render it read-only. For example, one may want to disable a form's submit button until the user has entered some required data.
  • Similarly, an author may want to include a piece of read-only text that must be submitted as a value along with the form.
  • Disabled controls

  • When set, the disabled attribute has the following effects on an element:

      
     
    • Disabled controls do not receive focus.
      
    • Disabled controls are skipped in tabbing navigation.
      
    • Disabled controls cannot be  successful.
  • How disabled elements are rendered depends on the user agent.

  •  

      

     

    Note. The only way to modify dynamically the value of the  disabled attribute is through a  script.
  • Read-only controls

  •   

    When set, the readonly attribute has the following effects on an element:

      
     
    • Read-only elements receive focus but cannot be modified by the user.
      
    • Read-only elements are included in tabbing navigation.
  •  
      

    The following elements support the readonly attribute: INPUT and  TEXTAREA.

  • Successful controls

      

    A successful control is "valid" for submission
