Set the input to read-only via disabled and readonly

Set the input to read-only via disabled and readonly
There are two ways to achieve read-only input: disabled and readonly.

Naturally, both results can only be read but not edited, but there are big differences between the two.

Disabled means that the input is invalid and its value will not be passed to any program, such as asp, php, etc.
Readonly simply cannot be edited and does not affect the transmission of its value.

Disabled usage: <INPUT type="text" name="username" value="james" disabled>
Readonly usage: <INPUT type="text" name="partNumber" value="1500" readonly>
