Displaying with jstl is more neat and less code than displaying with jsp

Copy codeThe Code is as follows:
<% @ Page language = "java" contentType = "text/html; charset = UTF-8" pageEncoding = "UTF-8" %>
<% @ Taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<% @ Page import = "java. util. List" %>
<% @ Page session = "true" %>
<% @ Page errorPage = "error. jsp" %>
<Html>
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = UTF-8">
<Title> Search </title>
<Script type = "text/javascript">
Function validate1 (){
Var page = document. forms [0]. page. value;
If (page. length <= 0 ){
Alert ("Enter the number of pages to jump! ");
} Else if (isNaN (page )){
Alert ("enter a valid number of pages! ");
} Else {
Document. forms [0]. submit ();
}
}
</Script>
