先给大家展示下效果图，效果图如下所示：

1.引用相关easyui.min.js，easyui-lang-zh_CN.js 等js 文件；

2.前台代码

<input type="text" id="txt_Type" style="display:none" /><div class="macFormItem" id="divSQXLH" runat="server"><label>售前支持序列号</label><div class="FormItemElement"><input id="txt_SQXLH" class="txt" type="text" style ="width:300px" readonly="readonly" /><input id="btn_selectSQXLH" type="button" value="选择序列号" style="margin-left: 5px; width: 90px" class="btn" /></div></div><%-- 弹出层--%><div id="menuContainer" style="position: absolute; background-color: white; border: 1px solid #cccccc; width: 306px; display: none;"><div style="font-size: 12px;">&nbsp;序列号:<input id="txt_Name" type="text" /><input id="btn_Search" type="button" style="margin: 10px 10px 10px 10px;" value="搜索" class="btn" /></div><div id="tt"></div><input id="btn_selectOk" type="button" value="确认" style="margin: 10px 10px 10px 10px;" class="btn" /><input id="btn_selectCancle" type="button" value="关闭" class="btn" /></div>

3.js 代码
