Certain jQuery object methods retrieve specific values (instead of modifying a state). An example of this is the val() method, which returns the current value of a text input element. In these cases, a statement such as $('#user-email').val() cannot be used for chaining as the return value does not reference a jQuery object.
In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such.
Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, key–value pair, or field–value pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.
Animate text and images in their document. Embed a ticker or other dynamic display that automatically refreshes its content with the latest news, stock quotes, or other data. Use a form to capture user input, and then process, verify and respond to that data without having to send data back to the server.

See text mode for hardware-implemented screen text attributes; particularly, VGA compatible text mode describes such text attributes on PC compatibles. Also, a text attribute may refer to an attribute (e.g. to an XML attribute), those value consists of a text.
Text content within an element is represented as a text node in the DOM tree. Text nodes do not have attributes or child nodes, and are always leaf nodes in the tree. For example, the text content "My Website" in the title element and "Welcome" in the h1 element in the above example are both represented as text nodes.
