Actionscript 3 Flex绑定列表selectedItem
我是flex新手,正在尝试组合两个列表选择的数据(请参见下面的代码):Actionscript 3 Flex绑定列表selectedItem,actionscript-3,apache-flex,actionscript,flex4,Actionscript 3,Apache Flex,Actionscript,Flex4,我是flex新手,正在尝试组合两个列表选择的数据(请参见下面的代码): 我想完成的是,当您从“reIndustry”中选择数据时,所选项目的更多数据将显示在“reQualifications”列表中 以下是我的数据: <s:ArrayList id="recruitIndustries"> <fx:Object industry="Admin/PA/Secretary" qualification="Other"/> <fx:O
我想完成的是,当您从“reIndustry”中选择数据时,所选项目的更多数据将显示在“reQualifications”列表中
以下是我的数据:
<s:ArrayList id="recruitIndustries">
<fx:Object industry="Admin/PA/Secretary" qualification="Other"/>
<fx:Object industry="Automotive" qualification="Painter"/>
<fx:Object industry="Building/Construct/Mine"/>
<fx:Object industry="Engineering"/>
<fx:Object industry="Finance/Accounting"/>
<fx:Object industry="FMCG"/>
<fx:Object industry="General Employment"/>
<fx:Object industry="Health and Skincare"/>
<fx:Object industry="Insurance"/>
<fx:Object industry="International"/>
<fx:Object industry="IT/Computer"/>
<fx:Object industry="Legal"/>
<fx:Object industry="Logistics"/>
<fx:Object industry="Management"/>
<fx:Object industry="Manufacturing"/>
<fx:Object industry="Medical"/>
<fx:Object industry="Part Time/ Temps"/>
<fx:Object industry="Professions"/>
<fx:Object industry="Retail"/>
<fx:Object industry="Sales and Marketing"/>
<fx:Object industry="Tourism/Hospitality"/>
</s:ArrayList>
如果可能,我如何添加更多值以显示在第二个列表“再鉴定”中。@RIAstar问题是正确的 您可以通过以下代码执行此操作:-
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import spark.events.IndexChangeEvent;
[Bindable]
private var moreDataProvider:ArrayCollection = new ArrayCollection();
private function itemClickHandler(event:IndexChangeEvent):void
{
moreDataProvider.removeAll();
if(Object(reIndustry.selectedItem).hasOwnProperty('qualification'))
moreDataProvider.addItem(reIndustry.selectedItem);
}
]]>
</fx:Script>
<s:layout>
<s:VerticalLayout/>
</s:layout>
<s:Label x="538" y="130" text="Industry of Interest:"/>
<s:List id="reIndustry" dataProvider="{recruitIndustries}" x="538" y="150" width="165" height="122"
labelField="industry" change="itemClickHandler(event)"/>
<s:Label x="723" y="130" text="Qualifications:"/>
<s:List id="reQualifications" dataProvider="{moreDataProvider}" x="723" y="150" width="165" height="122"
labelField="qualification"/>
但每个行业只有一项资格。为什么您需要在列表中表示这一点?
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import spark.events.IndexChangeEvent;
[Bindable]
private var moreDataProvider:ArrayCollection = new ArrayCollection();
private function itemClickHandler(event:IndexChangeEvent):void
{
moreDataProvider.removeAll();
if(Object(reIndustry.selectedItem).hasOwnProperty('qualification'))
moreDataProvider.addItem(reIndustry.selectedItem);
}
]]>
</fx:Script>
<s:layout>
<s:VerticalLayout/>
</s:layout>
<s:Label x="538" y="130" text="Industry of Interest:"/>
<s:List id="reIndustry" dataProvider="{recruitIndustries}" x="538" y="150" width="165" height="122"
labelField="industry" change="itemClickHandler(event)"/>
<s:Label x="723" y="130" text="Qualifications:"/>
<s:List id="reQualifications" dataProvider="{moreDataProvider}" x="723" y="150" width="165" height="122"
