Описание тега hidden-field
An HTML Input element that users do not see or interact with. It can hold a value and is often used to store client-side variables.
As defined from w3.org:
An INPUT element with `TYPE=HIDDEN' represents a hidden field. The user does not interact with this field; instead, the VALUE attribute specifies the value of the field. The NAME and VALUE attributes are required.
For example:
<input type=hidden name=context value="l2k3j4l2k3j4l2k3j4lk23">
This element is available in the following versions of HTML:
- HTML 3.2
- HTML 4.0
- HTML 5
- XHTML 1.0
It is important to note that users are able to see the hidden values if they view the source of the page. Hidden fields should never be used to store sensitive information like passwords or credit card information. A good programming guideline is to only use the hidden field to store information that the page has generated or information the user would not know or understand.
