Атрибут disabled

Sometimes, we required to display form fields in non-editable mode. We can achieve this functionality by setting read-only or disabled attribute to form fields (textbox, label, checkbox, text area). Before using both these attributes, we should understand the key differences between read only and disabled attributes.

Difference between disabled and read only attributes

Disabled attribute

Disabled form fields or elements values don’t post to the server for processing.

Disabled form fields or elements don’t get focus.

Disabled form fields or elements are skipped while tab navigation.

Some browsers (Like IE) provide default style (Gray out or emboss text) for disabled form fields or elements.

Read Only Attribute

Read Only form fields or elements values post to the server for processing.

Read Only form fields or elements get focus.

Read Only form fields or elements are included while tab navigation.

Some browsers do not provide default style for Read-Only form fields or elements.

Note

We can’t set readonly attribute to all the form fields or elements. The <SELECT>. <OPTION>. and<BUTTON> elements do not have readonly attributes while they can have disabled attributes.

Set Disabled Attribute
