The fn:indexOf() function returns the index within a string of a specified substring.
The fn:indexOf() function has following syntax:
int indexOf(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="string1" value="This is first String."/> <c:set var="string2" value="This <abc>is second String.</abc>"/> <p>Index (1) : ${fn:indexOf(string1, "first")}</p> <p>Index (2) : ${fn:indexOf(string2, "second")}</p> </body> </html> |
This would produce following result:
Index (1) : 8 Index (2) : 13 |
