这个话题已经在网上讨论过好几次了,但所有的话题都没有帮助我解决我的问题。我的 javascript 代码接收 JSON 嵌套数据。所有 JSON 数据 1 级数据都在网格面板中转录,但所有子数据都没有。我尝试了很多方法,但不可能。这就是为什么我请你帮助我。
我的 JSON:
{
"success":true,
"error":false,
"redirectUrl":null,
"fund":[{
"cat_id":1,
"catname":"Europe OE Japan Large-Cap Equity",
"region":{
"region_id":2,
"region_name":"JAPAN"
}
},{
"cat_id":2,
"catname":"Europe OE Europe Large-Cap Growth Equity",
"region":{
"region_id":1,
"region_name":"EUROPE"
}
}]
}
我的型号:
var Recommended = new function() {
this.DataModel = function() {
Ext.define('Fund', {
extend: 'Ext.data.Model',
fields: [{
name: 'catname',
type: 'string'
},{
name: 'cat_id',
type: 'int'
}],
proxy :{
type: 'rest',
url: application +'directory/function',
reader: {
type: 'json',
root: 'fund'
}
},
associations: [{
type: 'hasOne',
model: 'Region',
primaryKey: 'region_id',
name:'region'
}]
});
Ext.define('Region', {
extend: 'Ext.data.Model',
fields: [{
name: 'region_name',
type: 'string'
},{
name: 'region_id',
type: 'int'
}]
});
}
我的商店和网格面板:
this.JSONstore = function() {
var storeRecommended;
storeRecommended = Ext.create('Ext.data.Store', {
model: 'Fund',
autoLoad:true,
groupField: 'region_name'
});
var colModel =
[
{
text: 'REGION',
width: 200,
dataIndex: 'region_name',
name:'region_name',
mapping:'region.region_name'
},{
text: 'MORNINGSTAR',
width: 300,
dataIndex: 'catname',
name:'catname'
}
];
var groupingFeature = Ext.create('Ext.grid.feature.Grouping',{
groupHeaderTpl: 'Classe: {name} ({rows.length} Item{[values.rows.length > 1 ? "s" : ""]})',
hideGroupedHeader: false
});
var grid = Ext.create('Ext.grid.Panel', {
renderTo: 'recommendedlists',
collapsible: true,
iconCls: 'icon-grid',
frame: true,
store: storeRecommended,
width: 1200,
height: 400,
title: 'Test',
resizable: true,
features: [groupingFeature],
columns: colModel,
fbar : ['->', {
text:'Clear Grouping',
iconCls: 'icon-clear-group',
handler : function(){
groupingFeature.disable();
}
}]
});
}
this.initControlsOnload = function() {
Recommended.DataModel();
Recommended.JSONstore();
}
} // close Recommended function
