HTML Input Attributes
The value Attribute
The value attribute specifies the initial value for an input field:
Example
form action=""
First name:
input type="text"name="firstname"value="John"
The disabled attribute specifies that the input field is disabled.
A disabled input field is unusable and un-clickable, and its value will not be sent when submitting the form:
Example
form action=""
First name:
input type="text"name="firstname"value="John" disabled
The readonly attribute specifies that the input field is read only (cannot be changed):
Example
form action=""
First name:
<input type="text"name="firstname"value="John" readonly>
