<logic:equal name="pageForm" property="centerID" value="<bean:write name='componentForm' property='centerID'/>">
<tr class="embedDataLevel1" onMouseOver="mouseOver(this);" onMouseOut="mouseOut(this);">
<td><bean:write name="componentForm" property="resourceID" filter="true"/></td>
<td><bean:write name="componentForm" property="resourceQty" filter="true"/></td>
<td><bean:write name="componentForm" property="rowDesc" filter="true"/></td>
</tr>
</logic:equal>

请教高手，value是变量，上以写法不能工作，用什么方法解决没有？thanks

问题解决，但是还是不够完美，供大家参考。
<logic:iterate id="componentForm" name="components" property="forms">


<bean:define id="centerid" name="componentForm" property="centerID" scope="page" type="java.lang.String"/>
<%
String currentID = (String) pageContext.getAttribute("centerid");
%>
<logic:equal name="pageForm" property="centerID" value="<%= currentID %>">
<tr class="embedDataLevel1" onMouseOver="mouseOver(this);" onMouseOut="mouseOut(this);">
<td><bean:write name="componentForm" property="resourceID" filter="true"/></td>
<td><bean:write name="componentForm" property="resourceQty" filter="true"/></td>
<td><bean:write name="componentForm" property="rowDesc" filter="true"/></td>
</tr>
</logic:equal>
</logic:iterate>

Posted by: fhk1999 Posted on: 2003-07-01 13:29 Why not evaluate the logic in action and put result in request object?

Posted by: 老刀 Posted on: 2003-07-05 12:09 hehe, I won't seperate the bean into several sub-beans.

Posted by: liuhey Posted on: 2003-07-24 14:58 我觉得是不是可以这么做： <bean:define id="center" name="componentForm" property="centerID"/> <logic:equal name="pageForm" property="centerID" value="<%=center%>"> ..... </logic:equal>

Posted by: coala Posted on: 2003-07-24 15:27 value The constant value to which the variable, specified by other attribute(s) of this tag, will be compared. (REQUIRED) (RT EXPR) 肯定可以用表达式。（RT EXPR）就代表了这个是可以用表达式的。多去查查strtus的英文文档，那里的资料最权威。

Posted by: robin Posted on: 2003-07-24 15:34 我的意见是model 2x比较tag来说要简单的多也灵活的多！
