SpringMVC+easyUI CRUD 增加数据C

浏览数：24 / 时间：2015年06月08日

接一篇文章，今天上午实现了增加数据。下面是Jsp，里面主要是看newUser()和saveUser().注意这函数里的url，newUser()里面去掉url属性。还要注意的一个问题

<div id="toolbar">
		<a href="javascript:void(0);" class="easyui-linkbutton" iconCls="icon-add" plain="true" onclick="newUser()">New User</a>
		<a href="#" class="easyui-linkbutton" iconCls="icon-edit" plain="true" onclick="editUser()">Edit User</a>
		<a href="#" class="easyui-linkbutton" iconCls="icon-remove" plain="true" onclick="removeUser()">Remove User</a>
	</div>

这里面,<a href="#" >的#要改为javvascript:void(0); 这样才不会出现新建用户时找不到页面的情况。

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
