The fn:startsWith() function determines whether an input string starts with a specified substring.
The fn:startsWith() function has following syntax:
boolean startsWith(java.lang.String, java.lang.String) |
Following is the example to explain the functionality of this function:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %> <html> <head> <title>Using JSTL Functions</title> </head> <body> <c:set var="string" value="Second: This is first String."/> <c:if test="${fn:startsWith(string, 'First')}"> <p>String starts with First</p> </c:if> <br /> <c:if test="${fn:startsWith(string, 'Second')}"> <p>String starts with Second</p> </c:if> </body> </html> |
This would produce following result:
String starts with Second |
