JSTL: Property Access
In this example we are going to show we can access the
property by using the dot(.) and [ ] operator.
Firstly we are going to make a form where we will enter
some values and those values will be shown to you. The value will be shown to
you in the following way. Firstly we will set the values which we have retrieved
from the form in the attribute var. After setting the values the
output will be displayed to you by using the <c:out> tag.
The code of the program is given below:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<html>
<head>
<title>Property Access</title>
</head>
<body>
<form method="post">Enter your name :
<input type="text" name="name" /><br><br>
Enter your password : <input type = "password" name = "password"/><br>
<input type="Submit" />
<br />
</form>
<c:if test="${pageContext.request.method=='POST'}">
<c:set var="username" value="name" /><br>
<c:set var ="userpwd" value ="password"/><br>
param.name = <c:out value="${param.name}" /><br>
param.password = <c:out value = "${param.password}"/><br>
param[name] = <c:out value="${param[username]}" /><br>
param[password] = <c:out value="${param[userpwd]}"/>
</c:if>
</body>
</html> |
