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.
