如何从Ext.data.Store中的xml获取数据
提问于 2013-07-08 21:19:33
你好，我是一个用sencha开发移动应用程序的新手。在这里发帖之前，我已经做了一个搜索，但我没有找到任何解决方案。我正在尝试从具有以下格式的xml中获取数据
<?xml version="1.0" encoding="UTF-8"?>
<rss
version="2.0"

</rss>下面是我的代码
Ext.regModel('test', {
fields: [{
name: 'image',
type: 'string'
}, {
name: 'name',
type: 'string'
}, {
name: 'small_desciption',
type: 'string'
}, {
name: 'position',
type: 'string',
}]
});
ToolbarDemo.views.Testtab = Ext.extend(Ext.Panel, {
title: "Test",
iconCls: "test",
styleHtmlContent: true,
style:"background-color:#FFFFFF;",
dockedItems: [
{
xtype: "toolbar",
title: "Test",
items : [
{ xtype : 'spacer' },
// { xtype : 'spacer' },
],
},
],
layout: {
type: 'fit'
},
initComponent: function() {
this.setLoading(true,true);
var proxyUrl = 'http://mydomain/newsfeed/'
var store = new Ext.data.Store({
model: 'test',
proxy: {
type: 'ajax',
url: proxyUrl,
reader: {
type: 'xml',
record: 'item',
}
},
datachanged: function(){
var items = [];
store.each(function(rec){
items.push({
html: [
'<div class="main"><div class="thumb"><div class="contain">{position}</div><div class="image"><img src="http://mydomain/{image}.jpg" width="280" height="100"></div></div><div class="mainentry"><div class="maintitle">{name}</div><div class="description">{small_desciption}</div></div></div>',
]
});
});
}
});
store.read();
ToolbarDemo.views.Testtab.superclass.initComponent.call(this);
} });
Ext.reg('testtab', ToolbarDemo.views.Testtab);我哪里做错了？
谢谢

var xmlString = <channel>.....</channel> //Your xml data in string format
parser = new DOMParser();
var xmlData = parser.parseFromString(xmlString.body,"text/xml");
var channel = xmlMessage.childNodes[0];
if(channel){
var image = xmlData.getElementsByTagName("image")[0].childNodes[0].nodeValue;
var position = xmlData.getElementsByTagName("position")[0].childNodes[0].nodeValue;
var name = xmlData.getElementsByTagName("name")[0].childNodes[0].nodeValue;
var small_desciption = xmlData.getElementsByTagName("small_desciption")[0].childNodes[0].nodeValue;
