关于如何使用struts标签输出值为map的list
类别: JAVA教程
最近在一个项目中,要将一个list在客户端输出,而list里面的每个值不是bean,而是map,想好好久,想了个办法,可以实现,代码如下
ArrayList testList=new ArrayList(); HashMap testMap1=new HashMap(); testMap1.put("grade","七年级"); testMap1.put("class","一班"); testMap1.put("master","张三"); testList.add(testMap1); HashMap testMap2=new HashMap(); testMap2.put("grade","八年级"); testMap2.put("class","二班"); testMap2.put("master","张三"); testList.add(testMap2); HashMap testMap3=new HashMap(); testMap3.put("grade","九年级"); testMap3.put("class","五班"); testMap3.put("master","李四"); testList.add(testMap3);
<table border="1" cellpadding="0" cellspacing="0" bordercolor="#0033CC" name="tableList"> <tr><td>master</td><td>class</td><td>grade</td></tr> <logic:iterate id="element" indexId="ind" name="testList" > <tr> <td> <logic:iterate id="elementValue" indexId="idx" name="element"> <logic:equal name="elementValue" property="key" value="master"> <bean:write name="elementValue" property="value"/> </logic:equal> </logic:iterate> </td> <td> <logic:iterate id="elementValue" indexId="idx" name="element"> <logic:equal name="elementValue" property="key" value="class"> <bean:write name="elementValue" property="value"/> </logic:equal> </logic:iterate> </td> <td><logic:iterate id="elementValue" indexId="idx" name="element"> <logic:equal name="elementValue" property="key" value="grade"> <bean:write name="elementValue" property="value"/> </logic:equal> </logic:iterate> </td> </tr> </logic:iterate> </table>
masterclassgrade还有更好的方法,欢迎交流,第一次在blog上发文,没有排版,请多见谅!
