RE: [flexcoders] Dynamic combobox from JSON request

[Alex Harui]

Arrays don't notify when you push items onto them, so you have to use
ArrayCollection or use a temporary Array and assign it to myList

Subject: [flexcoders] Dynamic combobox from JSON request

 

Hello all, I have a Json request that I get from PHP backend. I am
learning so I have created a dynamic list for a combo box. The
problem is that when I press a button and it gets the data, I then go
to the combo box and I see 1 entry. If I then select the combo box
again I then will see all the entries. Not sure how to have all the
entries show the first time I select the combo box. Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> "
layout="absolute">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
import com.adobe.serialization.json.JSON;

[Bindable]
public var myList:Array = new Array();

public function personJSON(event:ResultEvent):void
{
var rawData:String = String(event.result);
var person:Object = JSON.decode(rawData);
trace(person[0].item1);
trace(person.length);
var x:Number;

for(x=0;x<person.length;x++){
trace(person[x].item1);
myList.push(person[x].item1);
}
trace(myList.length);
}
public function clearArray():void
{
myList = [];
cmboOne.text = 'Choose';
}
]]>
</mx:Script>
<mx:HTTPService id="personRequest"
url="http://127.0.0.1/test/Class/InventoryRequest.php
<http://127.0.0.1/test/Class/InventoryRequest.php> " 
useProxy="false" method="GET" resultFormat="text" 
result="personJSON(event)">
<mx:request xmlns="">
<getPerson>"true"</getPerson>
</mx:request>
</mx:HTTPService>
<mx:Panel x="401" y="294" width="250" height="275" layout="absolute">

<mx:Button x="69" y="121" label="Get Info"
click="personRequest.send()" id="send_btn"/>
<mx:Button id="aryClear" click="clearArray()" label="Clear" x="78"
y="151"/>
</mx:Panel>
<mx:ComboBox id="cmboOne" dataProvider="{myList}" rowCount="6"
x="157" y="44"/>

</mx:Application>

Thanks,
