我正在尝试访问 itemRenderer 中 DataGridColumn 的数据字段。下面是数据网格:
<mx:Script>
<![CDATA[
[Bindable] public var weeksOfMoth:ArrayCollection = new ArrayCollection([
{monday:30, tuesday:31, wednesday:1, thursday:2, friday:3, saturday:4, sunday:5},
{monday:6, tuesday:7, wednesday:8, thursday:9, friday:10, saturday:11, sunday:12},
{monday:13, tuesday:14, wednesday:15, thursday:16, friday:17, saturday:18, sunday:19},
{monday:20, tuesday:21, wednesday:22, thursday:23, friday:24, saturday:25, sunday:26},
{monday:27, tuesday:28, wednesday:29, thursday:30, friday:1, saturday:2, sunday:3}
]);
]]>
</mx:Script>
<mx:DataGrid dataProvider="{weeksOfMoth}" >
<mx:columns>
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="monday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="tuesday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="wednesday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="thursday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="friday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="saturday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="sunday" />
</mx:columns>
</mx:DataGrid>
这是我的 ItemRenderer:
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Box >
<!-- How do I get the dataField here?? -->
<mx:Label text="{data[dataField]}" />
</mx:Box>
</mx:Canvas>
在itemRenderer的set data函数中,我收到了一整周(可以),但是itemRenderer不知道使用哪一天,因为dataField是未知的。有谁知道如何在 itemRenderer 中访问这个 dataField?
