YUI DataTable排序

Question

我正在使用YUI数据表为一些统计信息创建一些基本的客户端排序，通过我创建的Web服务返回。不太想弄清楚YUI的ajax数据源的东西，所以我通过jquery和addRow（）来加载数据。问题是，所有的数据都没有正确排序。字符串字段似乎是一个随机顺序，并且数字/浮点列似乎按字符串排序（7显示在635之上）。

初始表定义如下：

var myColumnDefs = [ 
    {key:"appname",label:"Application Name", sortable:true}, 
    {key:"membercount",label:"Member Count",formatter:YAHOO.widget.DataTable.formatNumber,sortable:true}, 
    {key:"loggedin",label:"Logged In",formatter:YAHOO.widget.DataTable.formatNumber,sortable:true}, 
    {key:"peakoccupance",label:"Peak Occupance",formatter:YAHOO.widget.DataTable.formatNumber,sortable:true}, 
    {key:"averageoccupance",label:"Average Occupance",formatter:YAHOO.widget.DataTable.formatFloat,sortable:true} 
]; 

this.myDataSource = new YAHOO.util.DataSource([]); 
this.myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSARRAY; 
this.myDataSource.responseSchema = { 
    fields: [{key:"appname", parser:YAHOO.util.DataSourceBase.parseString}, 
     {key:"membercount", parser:YAHOO.util.DataSourceBase.parseNumber}, 
     {key:"loggedin", parser:YAHOO.util.DataSourceBase.parseNumber}, 
     {key:"peakoccupance", parser:YAHOO.util.DataSourceBase.parseNumber}, 
     {key:"averageoccupance", parser:YAHOO.util.DataSourceBase.parseNumber} 
    ] 
}; 

this.myDataTable = new YAHOO.widget.DataTable("markup", myColumnDefs, this.myDataSource, 
     {sortedBy:{key:"membercount",dir:"desc"}} 
); 

数据被加载这样的：

function xmlCallback(xml){ 
    if($(xml).find('memberCount').text() != "0"){ 
    var appName = $(xml).find('appname').text(); 
    var appID = $(xml).find('appid').text();   
    var memberCount = $(xml).find('memberCount').text(); 
    var zoneOccupance = $(xml).find('zoneOccupance').text(); 
    var peakOccupance = $(xml).find('peakOccupance').text(); 
    var averageOccupance = $(xml).find('averageOccupance').text(); 

    console.log(appName+" loaded..."); 

    if(memberCount != "0"){ 

     var allData = { 
     row: count, 
     appname: appName, 
     membercount: memberCount, 
     loggedin: zoneOccupance, 
     peakoccupance: peakOccupance, 
     averageoccupance: averageOccupance 
     }; 

     sococo.myDataTable.addRow(allData, count); 
     count++; 
     $("appsloaded").html(count); 
    } 
    else{ 
     appCount--; 
     $("totalapps").html(appCount); 
    } 
    } 
} 

填充的一切，我只是得到一个法士特排序顺序。我在这里忘了什么？

好了，在雅虎的样本之一查找信息的随机位后想通了这一点。显然，如果您在更新之后未明确将sortedBy字段设置为null，并且之前已声明sortedBy选项，则它将保留先前找到的排序顺序。我的猜测是某种缓存，所以它不会执行同样昂贵的客户端反复排序。

这样解决了这个代码是以下几点：

var allData = { 
    row: count, 
    appname: String(appName), 
    membercount: Number(memberCount), 
    loggedin: Number(zoneOccupance), 
    peakoccupance: Number(peakOccupance), 
    averageoccupance: Number(averageOccupance) 
}; 

sococo.myDataTable.addRow(allData, count); 
sococo.myDataTable.set("sortedBy", null);
