SenchaTouch2.3.1 正在使用listpaging以及pullrefresh插入 分页演示样品做

实际上本实施例是相对简单的。自定义PullRefreshFn插头继承Ext.plugin.PullRefresh。 主要是其附加refreshFn下拉监控事件。

listpaging么改动。再将这两个插件加入到 list中。

本例未採用MVC模式。

app.js代码例如以下：

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: '下拉能够更新',
		  lastUpdatedText:"上次刷新时间",
		  lastUpdatedDateFormat:"Y-m-d H:i",
		  releaseText:"松开開始更新",
		  loadedText:"载入完毕"
    },
    
    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()
        );
        
    }
});

index.html 例如以下：主要有一个样式在主页

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>index.html</title>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">

    <script type="text/javascript" src="app.js"></script>
    <style type="text/css">
    .user_img{
    	border: 1PX solid black; 
    	 500px;
    	margin: 5 5 5 5;
    	font-size: 8px;
    }
    </style>
  </head>
  <body>
  </body>
</html>

Eclipse 项目结构：

演示效果例如以下：

首次訪问显示第一页：

最后一页：

下拉刷新效果为:又一次载入第一页。
