程序调用例子:
<% //接收参数 String type = StringUtil.fixString(request.getParameter("type")); out.println("type==="+type); request.setAttribute("type2",type); %> 根据参数判断类型: <table width="90%"> <tr height="25"> <td width="25%" align="left" nowrap>单据类型: <select name="dj_type" id="dj_type"> <option value="RK" ${type2=='RK' ? 'selected':''}>商品入库单</option> <option value="CK" ${type2=='CK' ? 'selected':''}>商品出库单</option> <option value="TH" ${type2=='TH' ? 'selected':''}>商品退货单</option> </select> </td> <td width="25%" align="left" nowrap>商品编码:<input type="text"/></td> <td width="25%" align="left" nowrap>商品名称:<input type="text"/></td> <td width="25%" align="left" nowrap></td> </tr> </table>
