将easyui treegrid导出为ex​​cel和PDF的方法

Question

我刚刚开始使用jquery和asp.net。我将 jeasy-ui tree-grid 与asp.net（我不使用mvc模式）集成在一起，我可以获得样本树网格。现在我需要将树形网格数据导出为ex​​cel格式和PDF格式。

我已经参考了堆栈溢出链接here

但我没有帮助我。任何人都可以帮助我吗？

我使用树形网格中提供的以下示例json

[{
"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"
        }]
    },{
        "id":22,
        "name":"MySQL",
        "size":"",
        "date":"01/13/2010",
        "state":"closed",
        "children":[{
            "id":221,
            "name":"my.ini",
            "size":"10 KB",
            "date":"02/26/2009"
        },{
            "id":222,
            "name":"my-huge.ini",
            "size":"5 KB",
            "date":"02/26/2009"
        },{
            "id":223,
            "name":"my-large.ini",
            "size":"5 KB",
            "date":"02/26/2009"
        }]
    }]
},{
    "id":3,
    "name":"eclipse",
    "size":"",
    "date":"01/20/2010",
    "children":[{
        "id":31,
        "name":"eclipse.exe",
        "size":"56 KB",
        "date":"05/19/2009"
    },{
        "id":32,
        "name":"eclipse.ini",
        "size":"1 KB",
        "date":"04/20/2010"
    },{

        "name":"notice.html",
