用怎么控制循环?

[frank1197]

在画面初期化的时候,页面就想显示固定的20条记录,用这个标签能不能实现...

<%
for(int i = 0;i<20;i++) {
%>
<tr>fafafa</tr>
<% } %>

就是想用<logic:iterate>标签代替上面的代码.....

<%
Vector animals = new Vector();
animals.addElement("Dog");
animals.addElement("Cat");
animals.addElement("Bird");
animals.addElement("Chick");
request.setAttribute("Animals", animals);
%>
<logic:iterate id="element" name="Animals">
<bean:write name="element"/><br>
</logic:iterate>

<logic:iterate id="aList" name="YourForm" property="YourDataList" indexId="indexId" length="20" offset="0">

offset指定从list的那个元素开始，length指定从list中取得多少个元素

给你看个实例，自己钻研下
<logic:notEmpty name="OutListForm" property="list">
<logic:iterate name="OutListForm" property="list" id="vo"
type="com.neusoft.wms.outwarehouse.outlist.form.OutListMovementForm">
<%index++; %>
<tr>

<td nowrap=true class=singleDetailData width="25">
<input type="checkbox" name='chk'
value='<bean:write name="vo" property="rowId"/>'
id='<bean:write name="vo" property="rowId"/>' />
</td>
<td nowrap=true class=singleDetailData width="">
<bean:write name="vo" property="billNo" />
</td>
<td nowrap=true class=singleDetailData width="">
<bean:write name="vo" property="originNo" />
</td>
<td nowrap=true class=singleDetailData width="">
<bean:write name="vo" property="businessDate" />
</td>
<td nowrap=true class=singleDetailData width="">
<bean:write name="vo" property="lovName" />
</td>
<td nowrap=true class=singleDetailData width="">
<input type="hidden" name="mainstatus[<%=index%>]" id="mainstatus[<%=index%>]" value='<bean:write name="vo" property="status" />'/>
<span id="status[<%=index%>]"></span>
<script language="javascript">
<!--
var status = '<bean:write name="vo" property="status" />';
var transferstatus =( status == '0' ? "初始" :
(status == '1' ? "已下架":"已记账"));
document.getElementById("status[<%=index%>]").innerHTML=transferstatus;
-->
</script>
</td>
<td nowrap=true class=singleDetailData width="" align="right">
<bean:write name="vo" property="totalQty"/>
</td>
</tr>
</logic:iterate>
</logic:notEmpty>

估计你看的懂

用logic:iterate 里的 length offset属性来实现

[zhangjg2124]

加这两个属性：length="20" offset="0" offset是设置开始的位置（“0”表示第一条），你也可以设置成其他地方开始

那你就给这固定的20条数据不就得了啊
