jsp分页组件的使用

<%
int cp = Integer.parseInt(request.getParameter("cp"));
int ls = Integer.parseInt(request.getParameter("ls"));
int count = Integer.parseInt(request.getParameter("count"));
String URL = request.getParameter("URL");
int allPage = (count -1)/ls +1;
int[] allLs = {2,5,10,20,50};
%>

<center style="font-size:13px; " mce_style="font-size:13px; ">
<form action="<%=URL %>"  id="myform">
<input type="button" value="首页" onclick="changeCp(1);" />
<input type="button" value="上一页" <%=cp == 1 ? "disabled" : ""%> onclick="changeCp(<%=cp-1 %>);" />
<input type="button" value="下一页" <%=cp == allPage ? "disabled" : ""%> onclick="changeCp(<%=cp+1 %>);" />
<input type="button" value="末页" onclick="changeCp(<%=allPage %>);" />
跳转到<input type="text" value="<%=cp%>" name="cp" size="2" id="cp"/>/<%=allPage %>
<input type="submit" value="转到" />
每页显示
<select name="ls" onchange="changeLs();">
<%
for(int i=0;i<allLs.length;i++){
%>
<option value="<%=allLs[i] %>" <%=allLs[i]==ls?"selected":"" %>><%=allLs[i] %></option>

}

</select>
