如何将tr的id设置为变量？？？？？？
如何将tr的id设置为变量？？？？？？我在js中要调用tr，所以取tr的id但是这个tr是由遍历一个list实现的！所以有多个tr！但是我想标示每个tr所以我想把tr的id设一个变量！！！
<logic:notEmpty name="assetList">
<logic:iterate id="myProject" name="assetList">
<tr id="">
<td class="pagezch">
<bean:write name="myProject" property="attachValue" />
</td>
<td class="pagezch">
<bean:write name="myProject" property="attachDate" />
</td>
<td class="pagezch">
<bean:write name="AsTreatmentDto" property="prepareFeeRate" />%
</td>
<td class="pagezch">
<bean:write name="myProject" property="attachPrepareFee" />
</td>
<td class="pagezch">
<img id="del" src="/asset/images/button_delete.gif" style="cursor:hand" border="0" onclick="validate('<bean:write name="AsTreatmentDto" property="projectID" />','<bean:write name="myProject" property="attachDate" />');" >
</td>
</tr>
</logic:iterate>
</logic:notEmpty>


[解决办法]

JScript code

<%int i=0;%><logic:iterate id="myProject" name="assetList"> <tr id="<%= i%>"> <td class="pagezch"> <bean:write name="myProject" property="attachValue" /> </td> <td class="pagezch"> <bean:write name="myProject" property="attachDate" /> </td> <td class="pagezch"> <bean:write name="AsTreatmentDto" property="prepareFeeRate" />% </td> <td class="pagezch"> <bean:write name="myProject" property="attachPrepareFee" /> </td> <td class="pagezch">    <img id="del"  src="/asset/images/button_delete.gif" style="cursor:hand" border="0" onclick="validate(' <bean:write name="AsTreatmentDto" property="projectID" />',' <bean:write name="myProject" property="attachDate" />');" > </td> </tr> <%i++;%></logic:iterate>

变量可以用你自己本身得到的那个日期（如果日期是唯一的）


<script language="javascript">
 function setID(trid){
    document.all(trid).style.display="none";
 }  
</script> 
<logic:notEmpty name="assetList">  
<logic:iterate id="myProject" name="assetList">  
<tr id=<bean:write name="myProject" property="attachDate" /> onclick="setId('<bean:write name="myProject" property="attachDate" /> ');" >  
<td class="pagezch">  
<bean:write name="myProject" property="attachValue" />  
</td>  
<td class="pagezch">  
<bean:write name="myProject" property="attachDate" />  
</td>  
<td class="pagezch">  
<bean:write name="AsTreatmentDto" property="prepareFeeRate" />%  
</td>  
<td class="pagezch">  
<bean:write name="myProject" property="attachPrepareFee" />  
</td>  
<td class="pagezch">  
  <img id="del"  src="/asset/images/button_delete.gif" style="cursor:hand" border="0" onclick="validate(' <bean:write name="AsTreatmentDto" property="projectID" />',' <bean:write name="myProject" property="attachDate" />');" >
