在jsp中选中checkbox后 将该记录的多个数据获取，然后传到Action类中进行后台处理 双主键情况下 *.hbm.xml中的写法
==========方法1：
--------1. 选相应的checkbox后 点删除按钮-------------
<!-- *******************删除******************* -->
<input type="image" alt="delete"
src="<%=request.getContextPath() %>/images/btnImg/btn_delete.gif"
id="doDelete" name="action:delLocationAction!delete"
class="button_image" onClick="return delCheck2();" />
--------2. jsp页面的代码---------------
<table id="datashow" align="center" border="1" class="tb3" width="100%">
<tr class="gridtitle">
<td align="center"><input type="checkbox" id="chkAll"
name="chkAll" onClick="checkboxcheck();"></td>
<td>aaa</td>
<td>bbb
<% String varWerks=""; %>
<input type="hidden" name="werks_N" value="<%=varWerks%>">
</td>
</tr>
<% //String varWerks=""; %>
<s:iterator value="pageBean.list" status="index" id="cu">
<s:if test="#index.odd == true">
<tr class="gridspan">
</s:if>
<s:else>
<tr>
</s:else>
<td align="center">
<input type="checkbox" id="cb" name="ids" value="<s:property value="lgort"/>" />
</td>
<td><s:property value="lgort" /></td>
<td><s:property value="werks" /></td>
</tr>
</s:iterator>
</table>
-------3. 引用js方法---------------------------------
<script src="<%=request.getContextPath() %>/js/CheckBox.js"
type="text/javascript"></script>
-------4. js方法------------
function delCheck2()
{
var c=checkedNums();
if(c==0)
{
alert("您至少选择一条记录作为删除的对象。");
return false;
}
if(confirm("您确实要删除这条记录吗？"))
{
//-------------
var count=0;
var tb= document.all.datashow;
var str2="";
if(tb!=null)
{
for(i=0;i<tb.rows.length;i++)
{
var var1=tb.rows[i].cells[0].children[0];
if(var1.tagName=="INPUT" )
{
if(var1.type=="checkbox")
{
if (var1.checked)
{
count=count+1;
var td1=tb.rows[i].cells[1].innerText;
var td2=tb.rows[i].cells[2].innerText;
if(str2=="")
{
str2=td2;
}
else
{
str2=str2+","+td2;
}
}
} // ----if(var1.type=="checkbox")------>>>>
} // ---if(var1.tagName=="INPUT" )------->>
} // ---for(i=0;i<tb.rows.length;i++)
/* 隐藏域记录选中的序列 */
window.form1.werks_N.value = str2;
/* 正常提交表单 */
window.form1.submit();
}// ----if(tb!=null)---->>
return true;
}
return false;
}
------------5. action类中的代码
//分解字符串
public String[] SplitStr(String s) {
String[] ss = new String[200];
// 在每个逗号字符处进行分解。
ss = s.split(",");
return ss;
}
public String delete() throws Exception
{
HttpServletRequest request = ServletActionContext.getRequest();
String[] ids = request.getParameterValues("ids");
if (ids == null)
{
return SUCCESS;
}
String[] ida=request.getParameterValues("werks_N");
//是一个字符串 要分解 slipe
System.out.println(ida[0]);
String[] ss=SplitStr(ida[0]);
for (int i = 0; i < ids.length; i++) {
System.out.println("print ids " + ids[i]);
LocationBean locationBean = new LocationBean();
locationBean.setLgort(ids[i]);
System.out.println("print ida " + ss[i]);
locationBean.setWerks(ss[i]);
locationService.deleteLocation(locationBean);
}
return SUCCESS;
}
======方法2======(简单)===========
---------1. jsp页面中的代码
<table id="datashow" align="center" border="1" class="tb3" width="100%">
<tr class="gridtitle">
<td align="center"><input type="checkbox" id="chkAll" name="chkAll" onClick="checkboxcheck();"></td>
<td>aaa</td>
<td>bbb</td>
</tr>
<s:iterator value="pageBean.list" status="index" id="cu">
<s:if test="#index.odd == true">
<tr class="gridspan">
</s:if>
<s:else>
<tr> </s:else>
<td align="center">
<input type="checkbox" id="cb" name="ids" value="<s:property value="%{lgort +‘ ‘+ werks}"/>" />
</td>
<td><s:property value="lgort" /></td>
<td><s:property value="werks" /></td>
</tr>
</s:iterator>
</table>

---------3. 双主键情况下 *.hbm.xml中的写法-----
