SenchaTouch2.3.1 中使用listpaging以及pullrefresh插件 做的分页示例
本实例其实也比较简单，自己定义一个PullRefreshFn插件继承Ext.plugin.PullRefresh。主要给其添加了refreshFn下拉监听事件。listpaging插件未做任何修改。再将这两个插件添加到 list中。
本例未采用MVC模式。
app.js代码如下：
Ext.require([‘Ext.form.Panel‘,
‘Ext.data.Store‘,
‘Ext.dataview.DataView‘]);
//---------------------------------------------------------------------------------
Ext.define(‘myapp.model.PullRefreshFn‘, {
extend: ‘Ext.plugin.PullRefresh‘,
alias: ‘plugin.pullrefreshfn‘,
requires: [‘Ext.DateExtras‘],
xtype:‘refreshFn‘,
config: {
refreshFn: null,
pullText: ‘下拉可以更新‘,
lastUpdatedText:"上次刷新时间",
lastUpdatedDateFormat:"Y-m-d H:i",
releaseText:"松开开始更新",
loadedText:"加载完成"
},
fetchLatest: function() {
if (this.getRefreshFn()) {
this.getRefreshFn().call(this, this);
this.setState("loaded");
this.fireEvent(‘latestfetched‘, this, ‘refreshFn, you have to handle toInsert youself‘);
if (this.getAutoSnapBack()) {
this.snapBack();
}
} else {
console.log(‘fetchLatest‘)
var store = this.getList().getStore(),
proxy = store.getProxy(),
operation;
operation = Ext.create(‘Ext.data.Operation‘, {
page: 1,
start: 0,
model: store.getModel(),
limit: store.getPageSize(),
action: ‘read‘,
sorters: store.getSorters(),
filters: store.getRemoteFilter() ? store.getFilters() : []
});
proxy.read(operation, this.onLatestFetched, this);
}
},
snapBack: function(force) {
if(this.getState() !== "loaded" && force !== true) return;
var that = this,
list = this.getList(),
scroller = list.getScrollable().getScroller(),
currentY = scroller.minPosition.y;
scroller.refresh();
scroller.minPosition.y = 0;
scroller.on({
scrollend: this.onSnapBackEnd,
single: true,
scope: this
});
this.setIsSnappingBack(true);
scroller.getTranslatable().translateAnimated(0, currentY, {duration: this.getSnappingAnimationDuration()});
setTimeout(
function () {
scroller.scrollTo(0,1);
scroller.scrollToTop();
},
that.getSnappingAnimationDuration()
);
}
});
//------------------------------------------------------------------------------------------
Ext.application({
name:‘MyApp‘,
icon:‘images/icon.png‘,
glossOnIcon:false,
phoneStarupScreen:‘images/starUp.png‘,
tabletStartupScreen:‘images/tablet.png‘,
launch:function(){
Ext.define(‘User‘,{
extend:‘Ext.data.Model‘,
config:{
fields:[
{name:‘id‘,type:‘string‘},
{name:‘name‘,type:‘string‘},
{name:‘img‘,type:‘string‘},
{name:‘age‘,type:‘string‘},
{name:‘url‘,type:‘string‘},
{name:‘email‘,type:‘string‘},
{name:‘info‘,type:‘string‘}
]
}
});
var userStore=Ext.create(‘Ext.data.Store‘,{
model:‘User‘,
id:‘storeId‘,
autoLoad:true,
pageSize:8,
proxy:{
type:‘ajax‘,
limitParam: ‘pageSize‘, //设置limit参数，默认为limit
pageParam: ‘page‘, //设置page参数，默认为page
url:‘ServerDataServlet‘,
reader:{
type:‘json‘,
rootProperty:‘users‘
}
},
listeners:{
load:function(store, records, successful, operation, eOpts){
if(!successful){
//这个事件具体的可以看API no more record 也会进入
// Ext.Msg.alert(userStore.getProxy().getReader().rawData.message);
}
}
}
});
var userTemplate = new Ext.XTemplate(
‘<tpl for=".">‘,
‘<div class="user_img"><img src=http://www.mamicode.com/"{img}" width="50" height="50"/>编号：{id}姓名：{name}年龄：{age}主页：{url}邮件：{email}个人信息:{info}服务器端模拟代码如下：
