TreePanel中加載數據我新的ExtJS的，我創建MVC應用程序。無法在extjs4
我想創建樹面板如下。
以下是我的模型文件
Ext.define('rt.model.userinproject', {
extend: 'Ext.data.Model',
proxy: {
type: 'memory'
},
fields: [
{ name: 'text', type: 'string'},
{ name: 'id', type: 'Number'}
]
});
以下是我的存儲文件
Ext.define('rt.store.userinproject', {
extend: 'Ext.data.TreeStore',
model: 'rt.model.userinproject',
root: {
text: 'Project 1',
id: 1,
expanded: true
},
folderSort: true,
sorters: [{
property: 'text',
direction: 'ASC'
}],
data: [
{
text: "Project 1",
id: 1,
expanded: true,
children: [
{
text: "Department 1",
id: 1,
cls: "folder",
children:[
{
text: "User 1",
id: 1,
leaf:true
},
{
text: "User 2",
id: 2,
leaf:true
},
{
text: "User 3",
id: 3,
leaf:true
},
{
text: "User 4",
id: 4,
leaf:true
},
{
text: "User 5",
id: 5,
leaf:true
}
]
},
{
text: "Department 2",
id: 2,
cls: "folder",
children:[
{
text: "User 6",
id: 6,
leaf:true
},
{
text: "User 7",
id: 7,
leaf:true
},
{
text: "User 8",
id: 8,
leaf:true
},
{
text: "User 9",
id: 9,
leaf:true
},
{
text: "User 10",
id: 10,
leaf:true
}
]
},
{
text: "Department 3",
id: 2,
cls:"folder",
children:[
{
text: "User 11",
id: 11,
leaf:true
},
{
text: "User 12",
id: 12,
leaf:true
},
{
text: "User 13",
id: 13,
leaf:true
},
{
text: "User 14",
id: 14,
leaf:true
},
{
text: "User 15",
id: 15,
leaf:true
}
]
}
]
},
{
text: "Project 2",
id: 1,
expanded: true,
children: [
{
text: "Department 1",
id: 1,
cls: "folder",
children:[
{
text: "User 1",
id: 1,
leaf:true
},
{
text: "User 2",
id: 2,
leaf:true
},
{
text: "User 3",
id: 3,
leaf:true
},
{
text: "User 4",
id: 4,
leaf:true
},
{
text: "User 5",
id: 5,
leaf:true
}
]
},
{
text: "Department 2",
id: 2,
cls: "folder",
children:[
{
text: "User 16",
id: 16,
leaf:true
},
{
text: "User 17",
id: 17,
leaf:true
},
{
text: "User 18",
id: 18,
leaf:true
},
{
text: "User 19",
id: 19,
leaf:true
},
{
text: "User 20",
id: 20,
leaf:true
}
]
},
{
text: "Department 3",
id: 2,
cls:"folder",
children:[
{
text: "User 21",
id: 21,
leaf:true
},
{
text: "User 22",
id: 22,
leaf:true
},
{
text: "User 23",
id: 23,
leaf:true
},
{
text: "User 24",
id: 24,
leaf:true
},
{
text: "User 25",
id: 25,
leaf:true
}
]
}
]
}
]
});
以下是我的視圖文件
Ext.define('rt.view.project.projectuser', {
extend: 'Ext.tree.Panel',
alias: 'widget.projectuser',
disabled: true,
border: false,
cls: 'projectuser',
autoScroll: true,
initComponent: function() {
Ext.apply(this, {
store: this.store,
items: {
title: 'User in project',
}
});
this.callParent(arguments);
},
});
當我運行的代碼，樹面板似乎空沒有樹。
我想要做的是，我想基於存儲項目ID上面
讓我知道如果你需要從我的任何其他信息秀樹。
誰能幫我關於此事。
在此先感謝。
你有什麼錯誤嗎？看看這個：http://stackoverflow.com/q/5933874/185655它應該幫助你。 – 2011-05-31 11:28:02
hello Abdel，我也檢查了代碼，但目前我沒有收到任何錯誤..我錯誤的'me.store.getRootNode不是一個函數'，我從該線程解決。目前我沒有錯誤。無論我在做什麼，事實上都沒有改變。我也嘗試使用extjs示例中給出的ajax代理。但它也加載空樹。你還有其他建議嗎？感謝 – amar4kintu 2011-05-31 11:46:35
但我沒有看到你重新分配存儲到'initComponent'方法樹（在上面的代碼） – 2011-05-31 12:03:38
