      com.raritantechnologies.searchApp.taglibrary.RequestParameterSwitchTag

public class RequestParameterSwitchTag

extends BodyTagSupport

Implements a JSP tag that conditionally displays its body contents depending on the result of a comparison between a tag attribute and the value of a request parameter.

Example:

 
  <quickstart:switch requestParam="format" matchValue="plain" stopOnMatch="yes">
  [other HTML or JSP tags]
  </quickstart:switch>
  
 

Tag attributes:

• requestParam : the name of a request parameter containing the value to be compared.
• matchValue : the value that is considered a positive match. (Case sensitive)
• stopOnMatch : if set to "yes", the page contents after the close of this tag will not be processed or included in output.

Rules for conditionally including the tag contents in the JSP output:

use case	requestParameter=	matchValue	result
case 1	"dog"	"dog"	show block
case 2	"dog"	"cat"	skip block
case 3	any value	null	show block
case 4	null or empty	"dog"	skip block
case 5	null or empty	null	show block
