web控制层struts2
<input type="hidden" name="staffPid" id="staffId"/>
工号：<input type="text" id="staffCode"/>
姓名：<input type="text" id="staffStaffName"/>
通过工号的自动补全可获取staffCode、staffStaffName、staffPid（隐藏Id），
通过姓名的自动补全可获取也可以获取staffCode、staffStaffName、staffPid（隐藏Id）。
巧妙的应用在于：
.result (function(event, data, formatted) {
$("#staffId").val(data.staffPid);
$("#staffCode").val(data.staffCode);
});
.result (function(event, data, formatted) {
$("#staffId").val(data.staffPid);
$("#staffStaffName").val(data.staffStaffName);
});
一看就明白怎么回事了，就不多说了。
中文问题也一并解决了：
String n = request.getParameter("staffStaffName");
String name = new String(n.getBytes("ISO-8859-1"),"UTF-8");
至于页面的编码统一一下就可以了。
