在用Struts的
<logic:iterate id="testqclist" name="testQCActionForm" ="result" indexId="index" >
<bean:write name="testqclist" property="saamsampleid" /> <bean:write name="testqclist" property="sampleid" />
<input type="hidden" name="calcresultVal" value="<bean:write name="testqclist" property="calcresult" />" >
</logic:iterate>
说明：
参数是Property参数
参数名称
说明
name
struts-config里面的ActionForm 的名字
property
Form里面的一个arraylist属性
id
标识名，和里面标签的name名字一样
IndexId
显示记录条数的index，
indexId：的有个用法是：<logic:iterate i>里面有checkbox的时候，要选择特定的记录数量的时候，可以用到这个属性。
这时要在FORM里添加几个属性
1． 给每个属性添加一个集合属性
2． 添加一个方法保存FORM的对象。返回一个 ArrayList 对象给FORM原有的那个
Result 属性。
在JSP页面里面
每个显示的数据里面都加一个HIDEEN
当提交的时候就可以吧记录保存在FORM里面的集合属性里面。
代码如下
Action:
protected void performDBTask (ActionFormBase actionForm,
HttpServletRequest request,
HttpServletResponse response
) throws SQLException{
String methodName = "performDBTask()";
//ActinForm
TestQCActionForm testQCActionForm = (TestQCActionForm)actionForm;
try{
ArrayList handExcel = testQCActionForm.handExcelList();
testQCActionForm.setResultlist(handExcel);
actionForm.setForward ("success");
} catch (Exception e){
System.err.println (className + "." + methodName + "==>" + e.getMessage ());
}
}
FORM代码=======================================
private String[] checkboxVal;
private String[] testidVal;
private String[] sampleidVal;
private String[] qctypecdVal;
private String[] datesampledVal;
private String[] testseqVal;
private String[] calcresultVal;
private String[] saamsampleidVal;
//Hander Select data
public ArrayList handExcelList (){
java.util.ArrayList list = new java.util.ArrayList ();
if (checkboxVal != null && checkboxVal.length > 0){
for (int i = 0; i < checkboxVal.length; i++){
int chkVal = Integer.parseInt(checkboxVal[i]);
TestQCActionForm checkform = new TestQCActionForm ();
checkform.setSaamsampleid (datesampledVal[chkVal].toString());
checkform.setSaamsampleid(saamsampleidVal[chkVal].toString());
checkform.setSampleid (sampleidVal[chkVal].toString());
checkform.setQctypecd (qctypecdVal[chkVal].toString());
checkform.setTestid (testidVal[chkVal].toString());
checkform.setTestseq (testseqVal[chkVal].toString());
checkform.setCalcresult(Double.parseDouble(calcresultVal[chkVal]));
checkform.setDatesampled(datesampledVal[chkVal].toString());
list.add (checkform);
}
}
return list;
}
JSP页面===========================================
<lims:notEmpty name="testQCActionForm" property="result">
<logic:iterate id="testqclist" name="testQCActionForm" property="result" indexId="index" >
<tr bgcolor="#FFFFFF" onMouseOver="this.bgColor='#ECF4F9'" onMouseOut="this.bgColor='#FFFFFF'">

</tr>
</logic:iterate>
</lims:notEmpty>
就是在啊ACTION里面转向（actionForm.setForward ("success");）之前设置显示信息
首先要在.propertits里面设置
如：
del.msg= You Deleted Form(s) successfully
在ACTION里面
ActionErrors errors = new ActionErrors ();
errors.add ("addInfoMsg", new ActionError ("del.msg"));
saveErrors (request, errors);
actionForm.setForward ("success");
web-xml
application
com.lims.resources.Resource
此外还有一些做法
表示 显示集合中的所有错误
表示显示存储在missing.name关键字的错误
