<title>JSTL測試1--c:forEach循環</title>
</head>
<body>
一、整數
<c:forEach var="i" begin="1" end="10" step="1">
<c:out value="" />,
</c:forEach><p>
二、計算x的平方
<table>
<tr><th>Value</th>
<th>Square</th></tr>
<c:forEach var="x" begin="0" end="10" step="2">
<tr><td><c:out value=""/></td>
<td><c:out value="0"/></td></tr>
</c:forEach>
</table> <p>
三、字符串"47,52,53,55,46,22,16,2" 分隔.
<table border="1">
<c:forTokens items="47,52,53,55,46,22,16,2" delims="," var="dailyPrice">
<tr><td><c:out value=""/></td></tr>
</c:forTokens>
</table><p>
四、使用步長
<table>
<tr><th>second</th>
<th>second</th></tr>
<c:forEach var="seconds" begin="0" end="1800" step="60">
<tr><td><c:out value=""/></td>
<td><c:out value=""/></td></tr>
</c:forEach>
</table> <p>
五、對數組進行循環<p>
<% int ai[] = {10, 20, 30, 40, 50};
pageContext.setAttribute("ary", ai);
%>
<c:forEach var="i" items="">
<c:out value=""/>*
</c:forEach><p>
<%
Cookie c=new Cookie("cookie1","one");
response.addCookie(c);
%>
<%
Cookie cookies[]=request.getCookies();
Cookie sCookie=null;
String sname=null;
String name=null;
if(cookies==null) // 如果沒有任何cookie
out.print("none any cookie");
else
{
//out.print(cookies.length + "<br>");
for(int i=0;i<cookies.length; i++) // 循環列出所有可用的Cookie
{
sCookie=cookies[i];
sname=sCookie.getName();
name = sCookie.getValue();
out.println(sname + "->" + name + "<br>");
}
}
%>
<table border="1" align="center">
<tr><th>Cookie Name</th>
<th>Cookie Value</th></tr>
<c:forEach var="cook" items="">
<tr><td><c:out value=""/></td>
<td><c:out value=""/></td></tr>
</c:forEach>
</table> <p>
六、字符串數組循環
<% String as[] = {
"A first string", "La deuxieme string", "Ella troisiemo stringo"
};
request.setAttribute("stringArray", as);
%><p>
<c:forEach var="string" items="">
<c:out value=""/><br>
</c:forEach>
七、枚舉
<%
Hashtable hashtable1 = new Hashtable();
pageContext.setAttribute("numberMap", hashtable1);
hashtable1.put(new Integer(1), "uno");
hashtable1.put(new Integer(2), "dos");
hashtable1.put(new Integer(3), "tres");
hashtable1.put(new Integer(4), "cuatro");
hashtable1.put(new Integer(5), "cinco");
hashtable1.put(new Integer(6), "seis");
hashtable1.put(new Integer(7), "siete");
hashtable1.put(new Integer(8), "ocho");
hashtable1.put(new Integer(9), "nueve");
hashtable1.put(new Integer(10), "diez");
java.util.Enumeration enumeration = hashtable1.keys();
pageContext.setAttribute("enumeration", enumeration);
%>
<c:forEach var="item" items="" begin="2" end="10" step="2">
<c:out value=""/><br>
</c:forEach><p>
八、map<p>
<c:forEach var="prop" items="" begin="1" end="5">
<c:out value=""/> = <c:out value=""/><br>
</c:forEach>
</body>
