关于easyui treegrid 的数据格式的修改 完成类似于id pid 的平行数据

这几天要用到easyui 的treegrid 感觉到他的数据格式封装太成问题了，比较麻烦 捉摸了几天做了如下修改，希望能帮助大家

这是他默认的数据格式

[{
    "id":1,
    "name":"C",
    "size":"",
    "date":"02/19/2010",
    "children":[{
        "id":2,
        "name":"Program Files",
        "size":"120 MB",
        "date":"03/20/2010",
        "children":[{
            "id":21,
            "name":"Java",
            "size":"",
            "date":"01/13/2010",
            "state":"closed",
            "children":[{
                "id":211,
                "name":"java.exe",
                "size":"142 KB",
                "date":"01/13/2010"
            },{
                "id":212,
                "name":"jawt.dll",
                "size":"5 KB",
                "date":"01/13/2010"
            }]
        }]

网络上百般查找得到一个结论 他也支持这种格式

{"total":7,"rows":[
    {"id":1,"name":"All Tasks","begin":"3/4/2010","end":"3/20/2010","progress":60,"iconCls":"icon-ok"},
    {"id":2,"name":"Designing","begin":"3/4/2010","end":"3/10/2010","progress":100,"_parentId":1,"state":"closed"},
    {"id":21,"name":"Database","persons":2,"begin":"3/4/2010","end":"3/6/2010","progress":100,"_parentId":2},
    {"id":22,"name":"UML","persons":1,"begin":"3/7/2010","end":"3/8/2010","progress":100,"_parentId":2},
    {"id":23,"name":"Export Document","persons":1,"begin":"3/9/2010","end":"3/10/2010","progress":100,"_parentId":2},
    {"id":3,"name":"Coding","persons":2,"begin":"3/11/2010","end":"3/18/2010","progress":80},
    {"id":4,"name":"Testing","persons":1,"begin":"3/19/2010","end":"3/20/2010","progress":20}
],"footer":[
    {"name":"Total Persons:","persons":7,"iconCls":"icon-sum"}
]}

赶脚整个人都好了 但是问题随之而来

1.这个_parentId 好丑能修改成自己想要的么？

2.这个要是出现下面这种有parentId但是parentId这条数据不存在的时候表格就会不显示数据

{"total":7,"rows":[
		                              {"id":2,"name":"Designing","begin":"3/4/2010","end":"3/10/2010","progress":100,"_parentId":1}
		                           ],"footer":[
		                               {"name":"Total Persons:","persons":7,"iconCls":"icon-sum"}
		                           ]}

有没有问题大家可以试试 下面直接提解决方法

1.很简单 批量替换就搞定（jquery.easyui.min.js、jquery.treegrid.js 搜索"_parentId" 全部替换为你想要得值就行 我是"pid"）ps:其实不用全部替换，直接把他取值的时候换一下就行了 不过这种最简单最粗暴而且没问题

2.这个就麻烦了 害我js调试了好久 我可是java程序员 不过还是被我找到了 修改源码jquery.easyui.min.js直接上个截图有注释

好了 搞定 鼓掌！
