OFBiz框架实现分页效果

1.freemarker写的ftl文件

susake.ftl 展示效果

<div id="findEmployment" >
<form >
<#if listIt?has_content>
<table border="1">
总的页数:<#if listSize%10 gt 0 > ${listSize%10+2} <#else> ${listSize%10+1} </#if>
总的条数:${listSize}
当前页数:${viewIndex+1}
当前页面的条数:<#if listSize/10 gt (viewIndex+1)> 10 <#else> ${listSize%10} </#if>

<tr>
<th>用户</th>
<th>日期</th>
<th>新订单</th>
<th>订单</th>
<th>账户</th>
<th>信息</th>
<th>标签</th>
<th>账户1</th>
<th>信息1</th>
<th>标签1</th>
<th>操作</th>
</tr>

<#list listIt as item>

<tr>
<td>${item.ordercount}</td>
<td>${item.date}</td>
<td>${item.qordercount}</td>
<td>${item.usercount}</td>
<td>${item.qsercount}</td>
<td>${item.zsercount}</td>

<td>${item.qorderrate}</td>
<td>${item.userrate}</td>

<td>
<a id="deleteorder"

<a id="updateorder"

<input type="hidden" id="pageNumber" name="VIEW_INDEX" value="${(viewIndex)!'0'}" />
<input type="hidden" id="pageSize" name="VIEW_SIZE" value="${(viewSize)!'10'}" />
</td>
</tr>

</#list>
</table>
</#if>
<#assign paginationUrl="SusakeGroupList${(conditionUrl)!}">
<#import "component://gbcm/webapp/gbcm/views/includes/button.ftl" as p>
<@p.SusakePage requestUrl=paginationUrl listSize=listSize/>
</form>
</div>

button.ftl 用作点击分页的页数链接
