協會我試圖從https://www.hnsearch.com/api煎茶觸摸2:名單人羣爲煎茶,touch2一個學習項目,在模型
用數據填充一個商店,我已經創建了模型並存儲爲跟隨,並在檢查查看我可以看到數據已收到並正確映射。
我不能弄清楚的問題是,如何顯示一個sencha xtype:list元素與嵌套在json(Model:SearchResultItem)中的實際結果項目。我嘗試了以下內容,它會給我一個帶有一個列表項的列表,其中包含結果,但是我想爲每個搜索結果列出一個列表項。
機型:
Ext.define('senchaHackerNews.model.Search', {
extend: 'Ext.data.Model',
config: {
fields: [{
name: 'hits',
type: 'int'
}],
associations: {
type: 'hasMany',
name: 'results',
model: 'senchaHackerNews.model.SearchResults',
associationKey: 'results'
}
}
});
Ext.define('senchaHackerNews.model.SearchResults', {
extend: 'Ext.data.Model',
config: {
fields: [{
name: 'score',
type: 'float'
}],
associations: {
type: 'hasOne',
name: 'item',
model: 'senchaHackerNews.model.SearchResultItem',
associationKey: 'item'
}
}
});
Ext.define('senchaHackerNews.model.SearchResultItem', {
extend: 'Ext.data.Model',
config: {
fields: [{
name: 'username',
type: 'string'
}, {
name: 'title',
type: 'string'
}, {
name: 'points',
type: 'int'
}, {
name: 'url',
type: 'string'
}, {
name: 'domain',
type: 'string'
}]
}
});
商店:
Ext.define('senchaHackerNews.store.Search', {
extend: 'Ext.data.Store',
requires: ['senchaHackerNews.model.Search'],
config: {
storeId: 'hnSearchStore',
model: 'senchaHackerNews.model.Search',
autoload: false,
proxy: {
type: 'jsonp',
// url: 'http://api.thriftdb.com/api.hnsearch.com/items/_search?q=ipad',
reader: {
type: 'json',
rootProperty: ''
},
callbackKey: 'callback'
}
}
});
視圖:
Ext.define('senchaHackerNews.view.Search', {
extend: 'Ext.navigation.View',
alias: 'widget.hnSearch',
xtype: 'hnSearch',
requires: ['Ext.field.Search'],
initialize: function() {
var xtpl = new Ext.XTemplate('<tpl for="results">{item.username} ---- {item.title} | <br></tpl>');
this.add([
{
xtype: 'container',
title: 'Search HN',
layout: 'vbox',
items: [{
xtype: 'searchfield',
placeHolder: 'Search HN News (at least 3 chars)',
listeners: {
scope: this,
clearicontap: this.onSearchClearIconTap,
keyup: this.onSearchKeyUp
}
}, {
xtype: 'list',
flex: 1,
itemTpl: xtpl,
store: 'hnSearchStore',
emptyText: 'No Matching Items',
}]
}
]);
this.callParent(arguments);
},
onSearchKeyUp: function(field) {
if(field.getValue() != '' && field.getValue().length > 3) {
var store = Ext.StoreMgr.get('hnSearchStore');
store.setProxy({
url: 'http://api.thriftdb.com/api.hnsearch.com/items/_search?q='+field.getValue()
});
store.load();
} else if(field.getValue() == '') {
Ext.StoreMgr.get('hnSearchStore').removeAll();
}
},
onSearchClearIconTap: function() {
Ext.StoreMgr.get('hnSearchStore').removeAll();
}
});

謝謝,您的解決方案適合我。我只需要找到另一種方法來訪問頂級模型中的'點擊'現在 – anduee 2013-04-15 07:58:39
