我有這樣的json。如何做在extjs數據綁定6
firstName: 'xyz',
comments : [{
emailAddress : "[email protected]", body : "PQR",
emailAddress : "[email protected]", body : "XYZ",
}]
我想在可編輯的文本字段中顯示firstName。並希望在網格中顯示評論。我無法理解如何去做。請幫助我。
我的觀點是下列:
Ext.define("SampleView", {
extend: "Ext.panel.Panel",
alias: 'widget.sample',
id : 'sampleVId',
requires: ['StudentViewModel'],
viewModel: {
type: 'StudentViewModel'
},
layout: {
type: 'vbox',
align: 'stretch'
},
initComponent: function() {
Ext.apply(this, {
items: [this.form(), this.grid()],
});
this.callParent(arguments);
},
grid: function(){
return {
xtype: 'grid',
reference: 'samplegrid',
id : 'samplegridId',
bind: {
store: '{comment}'<-- not able to do the binding
},
flex:1,
margin: 10,
plugins: {
ptype: 'rowediting',
clicksToEdit: 2
},
columns: [{
text: 'Email',
dataIndex: 'email',
flex: 1,
editor: {
allowBlank: false
}
}, {
text: 'Role',
dataIndex: 'body',
}],
}
}
},
form : function(){
return{
xtype : 'form',
items:[{
xtype: 'textfield',
fieldLabel: 'First Name',
bind: {
value: '{firstName}'<---- how to bind this valuw to textfield
}
}]
}
}
});
我的視圖模型是這樣的:
Ext.define('StudentViewModel', {
extend: 'Ext.app.ViewModel',
alias:'viewmodel.StudentViewModel',
requires: [
'Student'
],
stores: {
orderStore: {
autoLoad:true,
type: 'sampleS'
}
}
});
我的模式是這樣的:
Ext.define('Student', {
extend: 'Ext.data.Model',
idProperty: 'Id',
schema: {
namespace: 'sample',
proxy: {
type:'ajax',
url: 'users.json',
reader:{
type:'json',
rootProperty:'data'
}
}
},
fields: [
{ name: 'Id', type: 'int' },
{ name: 'firstName', type: 'string' },
]
});
