queryvalue

Queryvalue is a term that generally refers to a specific piece of data or a parameter extracted from a query string. Query strings are a part of URLs, typically appearing after a question mark, and are used to pass information from a web browser to a web server. They consist of key-value pairs separated by ampersands. For example, in the URL http://example.com/search?q=wiki&sort=asc, "q" and "sort" are keys, and "wiki" and "asc" are their respective values.

When a web application receives such a URL, it can parse the query string to access these values. A "queryvalue" in this context would be the data associated with a particular key. In the example above, "wiki" is the queryvalue for the key "q," and "asc" is the queryvalue for the key "sort." Developers use queryvalues to dynamically alter the content or behavior of a web page without requiring a new URL to be loaded. This is common for search parameters, filtering options, pagination identifiers, and other forms of user input or configuration that are passed through the URL. Many programming languages and web frameworks provide built-in functions or libraries to easily extract and utilize these queryvalues from incoming requests.
