In World Wide Web, a query string is a part of a URL that contains data to be passed to web applications (http://en.wikipedia.org/wiki/Query_string).
The query string is composed of a series of field – value pair. Below is the pattern of query string:
field1=value1&field2=value2&field3=value3
An URL that contains query string can be depicted as follow:
http://test.com/tag?name=alma&role=user
The URL and query string separated by a question mark (?). Query string consist of two parts (field and value), and each of pair separated by ampersand (&). So the example above consists of two query strings which are name and type with value of each field ‘alma’ and ‘user’ respectively.
We can retrieve the query string values programmatically and used that values. Now we will learn how to get the query string values in ASP.NET and Javascript.
