页面主要代码easyDemo1.jsp:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
最主要的easyCrud.js代码如下:
$(function(){
$('#ff').hide();
$('#tt').datagrid({

});
$.messager.alert('add','添加信息成功!!!','info',function(){

}

$.messager.alert('warning','请选择一行数据','warning');
}
}
function edit(){
$('#ff').form('submit',{
url: 'easyUpdate.action?id='+id,
onSubmit:function(){ return $('#ff').form('validate');},
success:function(){
$.messager.alert('edit','修改信息成功!!!','info');
close2();
}
});
$('#tt').datagrid({
url:'easyAction.action',
loadMsg:'更新数据......'
});
}
function del(){
var selected = $('#tt').datagrid('getSelected');
if(selected){
$.messager.confirm('warning','确认删除么?',function(id){
if(id){
id = selected.id;
$.ajax({
type:"POST",
url:"easyDel.action",
data:"id="+id,
dataType:"xml",
success:function callback(){}
});
$('#tt').datagrid('reload');
}
});
}else{
$.messager.alert('warning','请选择一行数据','warning');
}
}
function query(){
var queryParams = $('#tt').datagrid('options').queryParams;
queryParams.queryWord = $('#qq').val();
$('#tt').datagrid({
url:'easyQuery.action'
});
displayMsg();
$('#query').window('close');
}
上述js代码写的有点臃肿，但是绝对能够精简的，只是时间关系和个人在js这块开发较少。
后台代码较多，本人已经将源码jquery_easyUI_demo.rar上传到网盘中，提供下载地址http://u.115.com/file/f46d05cd01#Download有兴趣的可以看看
