我是sencha touch的新手,我在使用ajax商店使用dataview时遇到了麻烦。
遵循我的代码:
在发布部分的app.js上:
Ext.define('SocializeApp.model.Friends', {
extend: 'Ext.data.Model',
config: {
fields: [
{name:'name' ,type:'string'},
{name:'id' ,type:'string'},
{name:'img' ,type:'string'}
]
}
});
Ext.define('SocializeApp.store.FriendStore', {
extend: 'Ext.data.Store',
config: {
model: 'SocializeApp.model.Friends',
storeId: 'FriendStore',
proxy: {
type: 'ajax',
url: 'http://socialize.localhost.com/friends.php',
reader: {
type: 'json',
rootProperty: 'friends'
},
autoLoad: 'true'
},
}
});
Ext.Viewport.add(Ext.create('SocializeApp.view.Main'));
在Main.js
中 Ext.define('SocializeApp.view.Main', {
extend: 'Ext.tab.Panel',
fullscreen: true,
xtype: 'main',
requires: ['Ext.TitleBar'],
config: {
tabBarPosition: 'bottom',
items: [{
title: 'Amigos',
iconCls: 'team',
items: [{
xtype: 'dataview',
store: 'FriendStore',
scrollable: {
direction: 'vertical'
},
tpl: ['{img} {id} {name}']
}]
}, {
title: 'time',
iconCls: 'time',
items: [{
html: '<h1> game </h1><src="resources/img/socialize-button.png" alt=""/>',
}]
}, {
title: 'Interesses',
iconCls: 'bookmarks',
items: [{
docked: 'top',
xtype: 'titlebar',
title: 'Getting Started'
}, {
xtype: 'video',
url: 'http://av.vimeo.com/64284/137/87347327.mp4?token=1330978144_f9b698fea38cd408d52a2393240c896c',
posterUrl: 'http://b.vimeocdn.com/ts/261/062/261062119_640.jpg'
}]
}]
}
});
我有点迷茫,我使用商店作为变量进行测试,在控制台中它给了我正确的数据,但没有选择此数据视图。
仅供参考JSON
{"friends":[{"name":"sakai","id":"123","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"124","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"125","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"126","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"127","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"128","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"129","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"110","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"},{"name":"sakai","id":"111","img":"http:\/\/try.sencha.com\/touch\/2.2.0\/docs\/Ext.dataview.DataView.2\/qr.png"}]}
我真的很感激任何帮助。

尝试这些(代码将想法结合起来)。
1 - 为您的dataview提供itemId,并在您的view initialize方法中加载商店。可能还想尝试将autoLoad设置为false。
2 - 有时我也明确地给出完整的商店参考而不仅仅是id,对于ex Ext.getStore(&#39; FriendStore&#39;)
3 - 你在使用MVC吗?你在app.js中声明了你的商店/模特吗?
Ext.application({
name: 'yourapp',
stores: ['FriendStore'],
models: ['Friends'],
launch: function() {
...
}
});
4 - 或者,只是想到这一点......将你的tpl更改为&item 39p&#39;
Ext.define('SocializeApp.view.Main', {
extend: 'Ext.tab.Panel',
fullscreen: true,
xtype: 'main',
requires: ['Ext.TitleBar', 'SocializeApp.store.FriendStore'],
config: {
tabBarPosition: 'bottom',
items: [{
title: 'Amigos',
iconCls: 'team',
items: [{
itemId: 'FriendsDataview',
xtype: 'dataview',
store: Ext.getStore('FriendStore'),
scrollable: {
direction: 'vertical'
},
itemTpl: ''.concat(
'<div>{img} {id} {name}</div>'
)
}]
}, {
title: 'time',
iconCls: 'time',
items: [{
html: '<h1> game </h1><src="resources/img/socialize-button.png" alt=""/>',
}]
}, {
title: 'Interesses',
iconCls: 'bookmarks',
items: [{
docked: 'top',
xtype: 'titlebar',
title: 'Getting Started'
}, {
xtype: 'video',
url: 'http://av.vimeo.com/64284/137/87347327.mp4?token=1330978144_f9b698fea38cd408d52a2393240c896c',
posterUrl: 'http://b.vimeocdn.com/ts/261/062/261062119_640.jpg'
}]
}]
},
initialize: function(){
var store = Ext.getStore('FriendStore');
var dv = Ext.ComponentQuery.query('dataview[itemId=FriendsDataview]')[0];
dv.setStore(store);
store.load(function(){
console.log(this);
});
}
});
