Question

我正在使用YUI数据表为某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，所以我在通过jquery和addRow（）加载数据。问题是，所有数据都没有正确排序。字符串字段似乎是一个随机顺序，数字/浮点列似乎按字符串排序（7出现在635以上）。

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"}}
);

数据加载如下：

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 );
    }
  }
}

所有东西都填充，我只是得到一个shite排序顺序。我忘记了什么？

谢谢，约什

好的，在雅虎的一个样本中找到一个随机信息之后想出来了。显然，如果在进行更新后没有将sortedBy字段显式设置为null，并且之前已经声明了sortedBy选项，它将保留先前找到的排序顺序。我的猜测是某种缓存，所以它不能执行同样昂贵的客户端反复排序。

所以修复此问题的代码如下：

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 );
