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

问题描述

我有对象的ArrayCollection。每个对象都具有以下键/值：

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

我要这个的ArrayCollection按日期排序，所以这将是从过去到present - 像这样：

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

我已经试过，没有prevail（不排序）以下

  VAR dateSort：分类=新的排序（）;
    dateSort.fields =新的SortField（日，假的，假的，真正的）;

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

// traceout
对于（VAR我：= 0; I＆LT; newAreaChartData.length;我++）
    迹线（对象＃+ I +：+ ObjectUtil.toString（newAreaChartData.getItemAt（ⅰ）））;
 

解决方案

这为我工作：

 为（i = 0; I＆LT; newAreaChartData.length ++我）{
    newAreaChartData [I] .formattedDate = getActualDate（newAreaChartData [I] .date）;
    newAreaChartData [I] .dateTime = newAreaChartData [I] .formattedDate.time;
    跟踪（newAreaChartData [I] .dateTime）;
}

    VAR dateSort：分类=新的排序（）;
    dateSort.fields =新的SortField（日期时间，假的，假的，真正的）;
    newAreaChartData.sort = dateSort;
    newAreaChartData.refresh（）;

对于（VAR我：= 0; I＆LT; newAreaChartData.length;我++）
    迹线（对象＃+ I +：+ ObjectUtil.toString（newAreaChartData.getItemAt（ⅰ）））;
 

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)));
