如何在 Flex 中对 ArrayCollection 进行排序 [英] How to sort an ArrayCollection in Flex

问题描述

我想按 fieldName 按升序对 Arraycollection 进行排序.这是我的代码，我想知道它是否正确.您有什么建议吗?

I want to sort an Arraycollection by fieldName as ascending. Here's my code and I want to know whether it's right. Do you have any suggestions?

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();}

推荐答案

您拥有的代码是正确的，除了类型.arrCol 应该是 ar.代码看起来几乎与博客中的代码Flex 示例，这也是正确的.

The code you have is correct, except for a type. arrCol should be ar. The code looks almost exactly like the code at the blog Flex Examples, which is also correct.

只是将 arrCol 更改为 ar 如下所示:

Just change is change arrCol to ar like below:

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];
    ar.sort = numericDataSort;
    ar.refresh();
}

不确定数字，但其他一切都是正确的.

Not sure with numeric but otherwise everything else is correct.
