ArrayCollection的排序，然后按日期和时间 - 的Flex [英] sort ArrayCollection by date then time - Flex

问题描述

我有，我想用日期，然后时间整理一个ArrayCollection（如果有两个项目具有相同的日期）。我把它按日期罚款（年/月/日）的排序，但我想不通的时间位，时间为24小时格式因此code将是基本相同的日期。

这是在code我用日期排序，它工作正常。

 进口mx.collections.SortField;
进口mx.collections.Sort;

私有函数的sort（）：无效
{
VAR dataSortField：=的SortField新的SortField（）;
dataSortField.name =日期;

VAR arrayDataSort：分类=新的排序（）;
arrayDataSort.fields = [dataSortField]

reminderXMLArray.sort = arrayDataSort;
reminderXMLArray.refresh（）;
}
 

解决方案

您可以使用此code按日期和时间排序：

 私有函数的sort（）：无效
{
    VAR dataSortField：=的SortField新的SortField（）;
    dataSortField.name =日期;
    dataSortField.compareFunction =功能（A：对象，B：对象）：INT {
        变种NA：数= a.date.getTime（）;
        VAR注：数= b.date.getTime（）;

        如果（的Na; NB）
            返回-1;

        如果（NA＆GT; NB）
            返回1;

        返回0;
    };

    VAR arrayDataSort：分类=新的排序（）;
    arrayDataSort.fields = [dataSortField]

    reminderXMLArray.sort = arrayDataSort;
    reminderXMLArray.refresh（）;
}
 

I have an ArrayCollection that I'd like to sort by date and then time (in case there's two items with the same date). I've got it sorting by date fine (YYYY/MM/DD) but I can't figure out the time bit, time is in 24 hour format so the code would be basically the same as for the date.

This is the code I used for the date sorting, it works fine.

import mx.collections.SortField;
import mx.collections.Sort;

private function sort():void  
{
var dataSortField:SortField = new SortField();
dataSortField.name = "date";

var arrayDataSort:Sort = new Sort();
arrayDataSort.fields = [dataSortField];

reminderXMLArray.sort = arrayDataSort;
reminderXMLArray.refresh();
}

解决方案

You can use this code to sort by date and time:

private function sort():void
{
    var dataSortField:SortField = new SortField();
    dataSortField.name = "date";
    dataSortField.compareFunction = function (a:Object, b:Object) : int {
        var na:Number = a.date.getTime();
        var nb:Number = b.date.getTime();

        if (na < nb)
            return -1;

        if (na > nb)
            return 1;

        return 0;
    };

    var arrayDataSort:Sort = new Sort();
    arrayDataSort.fields = [dataSortField];

    reminderXMLArray.sort = arrayDataSort;
    reminderXMLArray.refresh();
}
