actionscript-3 – 如何在Flex中对ArrayCollection进行排序

我想按字段名称将Arraycollection排序为升序.这是我的代码,我想知道它是否正确.你有什么建议吗？

public static function arrayCollectionSort(ar:ArrayCollection,fieldName:String,isNumeric:Boolean):void 
    {var dataSortField:SortField = new SortField();
        dataSortField.name = fieldName;
        dataSortField.numeric = isNumeric;
        var numericDataSort:Sort = new Sort();
        numericDataSort.fields = [dataSortField];
        arrCol.sort = numericDataSort;
        arrCol.refresh();}

解决方法

您拥有的代码是正确的,但类型除外. arrCol应该是ar.代码看起来几乎与博客 Flex Examples中的代码完全一样,这也是正确的.

只需更改是将arrCol更改为如下所示：

public static function arrayCollectionSort(ar:ArrayCollection,isNumeric:Boolean):void 
{
    var dataSortField:SortField = new SortField();
    dataSortField.name = fieldName;
    dataSortField.numeric = isNumeric;
    var numericDataSort:Sort = new Sort();
    numericDataSort.fields = [dataSortField];
    ar.sort = numericDataSort;
    ar.refresh();
}

不确定数字,但其他一切都是正确的.
