Extjs DataView ArrayStore问题
我有以下JS:
http://monobin.com/__m1c171c4e
和以下代码:
代码:
var tpl = new Ext.XTemplate(
'<tpl for=".">',
'<div class="thumb-wrap" id="{Name}">',
'<div class="thumb"><img src="{ImageMedium}" title="{Name}"></div>',
'<span class="x-editable">{Name}</span></div>',
'</tpl>',
'<div class="x-clear"></div>'
);
var store = new Ext.data.ArrayStore({
fields: [{ name: 'name' }, { name: 'ImageMedium'}],
data: res.data.SimilarArtists
});
var panel = new Ext.Panel({
frame: true,
width: 535,
autoHeight: true,
collapsible: true,
layout: 'fit',
title: 'Simple DataView (0 items selected)',
items: new Ext.DataView({
store: store,
tpl: tpl,
autoHeight: true,
multiSelect: true,
overClass: 'x-view-over',
itemSelector: 'div.thumb-wrap',
emptyText: 'No images to display',
prepareData: function (data) {
data.Name = Ext.util.Format.ellipsis(data.Name, 15);
return data;
},
plugins: [
new Ext.DataView.DragSelector(),
new Ext.DataView.LabelEditor({ dataIndex: 'name' })
],
listeners: {
selectionchange: {
fn: function (dv, nodes) {
}
}
}
})
});
所以绑定DataView 到 res.data.SimilarArtists 的子数组
但似乎什么也没有发生?
甚至没有调用prepareData?
我做错了什么?

new Ext.DataView.LabelEditor({ dataIndex: 'name' })
],
listeners: {
selectionchange: {
fn: function (dv, nodes) {
}
}
}
})
});
So binding the DataView to the child array of res.data.SimilarArtists
But nothing seems to happen?
prepareData doesnt even get called?
What am i doing wrong?

您链接到的数据结构是 JSON,而不是数组数据。尝试切换到 JsonStore 。请注意,JsonStore 预先配置了 JsonReader 和 HttpProxy(远程数据源),用于从 url 加载数据。如果您需要从本地数据加载 JSON,那么您必须使用 JsonReader 和 MemoryProxy 创建一个通用存储。
The data structure you've linked to is JSON, not array data. Try switching to a JsonStore instead. Note that a JsonStore is preconfigured with a JsonReader and an HttpProxy (remote data source) and is intended for loading the data from a url. If you need JSON loaded from local data, then you'll have to create a generic store with a JsonReader and MemoryProxy.
