比如在文本框输入数量“1”，提交得到结果“1台”
<tr>
<td align="right" class="td1">设备数量：</td>
<td align="left" class="td2" >
<form:input path="deviceNum" id="deviceNum" htmlEscape="false" maxlength="50" class="required" onblur="require('deviceNum','deviceNum_tipContext','设备数量不能为空');checkMemory('deviceNum','deviceNum_tipContext','设备数量必须为正数')"/>
<span class="required">*</span>
------解决思路----------------------
后台在获取到输入内容之后，拼接字符串。例如：String count = request.getParameter("count "); count1=count+“台”；前台回显这个count1就行了
