我正在使用。例如,我的申请

I m 试图添加

我试图在一份单独的档案中确定两根树,我的主要档案是布局,需要在我手中的表格中添加这一(和其他)内容。

www.un.org/Depts/DGACM/index_spanish.htm 问题在于,Im使用蚊帐,而这个例子正在使用php。

我如何能够在互联网上开展这项工作?

我的守则是:

Ext.require([ * ]);

var store = Ext.create( Ext.data.TreeStore , {
    proxy: {
        type:  ajax ,
        url:  get-nodes.php 
    },
    root: {
        text:  Ext JS ,
        id:  src ,
        expanded: true
    },
    folderSort: true,
    sorters: [{
        property:  text ,
        direction:  ASC 
    }]
});

var tree = Ext.create( Ext.tree.Panel , {
    id:  tree ,
    store: store,
    width: 250,
    height: 300,
    columnWidth: 0.5,
    viewConfig: {
        plugins: {
            ptype:  treeviewdragdrop ,
            appendOnly: true
        }
    }
   // ,renderTo: document.body
});

var store2 = Ext.create( Ext.data.TreeStore , {
    proxy: {
        type:  ajax ,
        url:  get-nodes.php 
    },
    root: {
        text:  Custom Ext JS ,
        id:  src ,
        expanded: true,
        children: []
    },
    folderSort: true,
    sorters: [{
        property:  text ,
        direction:  ASC 
    }]
});

var tree2 = Ext.create( Ext.tree.Panel , {
    id:  tree2 ,
    width: 250,
    height: 300,
    columnWidth: 0.5,
    store: store2,
    viewConfig: {
        plugins: {
            ptype:  treeviewdragdrop ,
            appendOnly: true
        }
    }
   // ,renderTo: document.body
});


Ext.define("Ext.app.myTwoTrees",{
extend:"Ext.panel.Panel",

width : 600,
height: 350,
layout:  column ,
items: [
         tree , tree2
       ]

});

我在表态中称:

 Ext.create( Ext.app.myTwotrees )

这里是先天。 php

Answer 1

我建议你把这个问题分为两部分:

(1) 更改<代码>url: 编号: to url: my-dotnet-url并作此改动。 NET page 回流静止的JSON或XML(硬编码树值)

That will confirm all your javascript, resources, etc. is working properly and that you are only asking a .NET question about how to output certain data.

2) 然后发现一个“网络”的例子,使你能够从获得数据的地方创建“JSON”或“XML”(很可能是一个数据库)。你们只需看一看你正确运作的静态数据。如果你不了解多少购买力平价。 NET 学习。要使你的产出正确,网络比试图从这个例子中赶走更容易。如果你坐下来,我再提出一个不同的问题,并询问如何以动态的方式编制从这一静态档案中得出的数据,而没有牵涉极端复杂因素的数据!

Hope this helps.

Answer 2

Try Dextop。它为伙伴关系之间的联系提供了一个应用框架。 NET and Ext JS.
