Today, I would like to summarize several useful html tags that are often used in development. unfamiliar people may not be quite clear about them. They are:

Readonly, disabled, autocomplete

Readonly indicates that the value of this field cannot be modified. It can only be used with type = "text". It can be copied, selected, and can receive the focus. The background will receive the passed value.

Readonly = "readonly"/>

Disabled indicates that the input element is disabled, cannot be edited, cannot be copied, cannot be selected, cannot receive focus, and no value is received in the background

Disabled = "disabled"/>

If you want to remove it, you 'd better add autocomplete = "off". The usage is as follows: autocomplete = "off"

Autocomplete = "off" id = "number"/>
