Actionscript：按日期排序ArrayCollection：YYYY-MM-DD [英] Actionscript: Sorting ArrayCollection by date: YYYY-MM-DD

问题描述

我有一个ArrayCollection对象。每个对象具有以下键/值：

  {date：2009-12-01，visits = 13555，bouceRate = 45} 
 {date：2009-12-05，visits = 46955，bouceRate = 45} 
 {date：2009-12-06，visits = 13685，bouceRate = 45} 
 {date：2009 -12-02，访问次数= 13685，bouceRate = 45} 
 {date：2009-12-04，访问= 68755，bouceRate = 45} 
 {date：2009-12-03，访问= 35875 ，bouceRate = 45} 
  

我需要按日期排序ArrayCollection，所以它将是从过去到现在 - 像这样：

  {date：2009-12-01，visits = 13555，bouceRate = 45} 
 {date：2009-12-02，visits = 13685，bouceRate = 45} 
 {date：2009-12-03，visits = 35875，bouceRate = 45} 
 {date：2009-12-04 ，访问= 68755，bouceRate = 45} 
 {date：2009-12-05，访问= 46955，bouceRate = 45} 
 {date：2009-12-06，访问= 13685，bouceRate = 45

我尝试过以下，不排序）：

  var dateSort：Sort = new Sort （）; 
 dateSort.fields = [new SortField（date，false，false，true）]; 
 
 newAreaChartData.sort = dateSort; 
 newAreaChartData.refresh（）; 
 
 // traceout 
 for（var i：int = 0; i< newAreaChartData.length; i ++）
 trace（Object＃+ i +：+ ObjectUtil.toString（newAreaChartData.getItemAt（i）））; 
  

解决方案

这对我有用：

$ b （i = 0; i newAreaChartData [i] .formattedDate = getActualDate（newAreaChartData [i] .date）;
newAreaChartData [i] .dateTime = newAreaChartData [i] .formattedDate.time;
trace（newAreaChartData [i] .dateTime）;
}

var dateSort：Sort = new Sort（）;
dateSort.fields = [new SortField（dateTime，false，false，true）];
newAreaChartData.sort = dateSort;
newAreaChartData.refresh（）;

for（var i：int = 0; i< newAreaChartData.length; i ++）
trace（Object＃+ i +：+ ObjectUtil.toString（newAreaChartData.getItemAt （一世）））;

I have an ArrayCollection of Objects. Each Object has the following keys/values:

{date: 2009-12-01, visits=13555, bouceRate=45}
{date: 2009-12-05, visits=46955, bouceRate=45}
{date: 2009-12-06, visits=13685, bouceRate=45}
{date: 2009-12-02, visits=13685, bouceRate=45}
{date: 2009-12-04, visits=68755, bouceRate=45}
{date: 2009-12-03, visits=35875, bouceRate=45}

I need to sort this ArrayCollection by date, so it would be from past to present - like so:

{date: 2009-12-01, visits=13555, bouceRate=45}
{date: 2009-12-02, visits=13685, bouceRate=45}
{date: 2009-12-03, visits=35875, bouceRate=45}
{date: 2009-12-04, visits=68755, bouceRate=45}
{date: 2009-12-05, visits=46955, bouceRate=45}
{date: 2009-12-06, visits=13685, bouceRate=45}

I have tried the following with no prevail (not sorting):

var dateSort:Sort = new Sort();
    dateSort.fields = [new SortField("date", false, false, true)];

newAreaChartData.sort = dateSort;
newAreaChartData.refresh();

// traceout
for (var i:int = 0; i <newAreaChartData.length; i++)
    trace ("Object #" + i + ": " + ObjectUtil.toString(newAreaChartData.getItemAt(i)));

解决方案

This worked for me:

for(i = 0; i < newAreaChartData.length; ++i) {
    newAreaChartData[i].formattedDate = getActualDate(newAreaChartData[i].date);
    newAreaChartData[i].dateTime =    newAreaChartData[i].formattedDate.time;
    trace(newAreaChartData[i].dateTime);
}

    var dateSort:Sort = new Sort();
    dateSort.fields = [new SortField("dateTime", false, false, true)];
    newAreaChartData.sort = dateSort; 
    newAreaChartData.refresh();

for (var i:int = 0; i <newAreaChartData.length; i++)
    trace ("Object #"+ i + ": " + ObjectUtil.toString(newAreaChartData.getItemAt(i)));
