Get text from a reapeater object - flex
I have a label that is using a repeater to get information form a database. Now I'm trying to pass the information in that label to another label component, but I haven't had any luck.
if I do a trace on the label in the repeater eg.
trace (Gotid.text);
I get this error in debug mode
warning: unable to bind to property 'user_name' on class 'Object' (class is not an IEventDispatcher) undefined
Any ideas on how I go about getting information form Gotid to display as text in another label?
k I'll try to make this as straight forward as possible
private function Getid():void { var stmt:SQLStatement = new SQLStatement(); stmt.sqlConnection = sqlConn; stmt.text = "SELECT * FROM tbl_animal WHERE animal_ptag='"+ptagInput.text+"'"; stmt.execute(); var result:SQLResult = stmt.getResult(); acGetid = new ArrayCollection(result.data); animalid.text = Gotid.text; trace (Gotid.text); }
-
<mx:Repeater id="getidrepeater" dataProvider="{acGetid}">
<mx:Label x="30" y="362" text="{getidrepeater.currentItem.animal_id}" id="Gotid"/>
</mx:Repeater>
<mx:Label x="30" y="388" text="Label" id=开发者_JAVA技巧"animalid"/>
I'm not sure how it relates to your user_name
error, but the Gotid
field in your main component will be an array of Labels, not a single Label field.
See Referencing Repeated Components
in this Adobe Docs page, for example.
Given that you're possibly getting multiple animals to fill in Gotid
with, I don't know how you know which to fill in the animalid
label. If you assume you're only going to get one, you could do:
animalid.text = Gotid[0].text;
trace (Gotid[0].text);
