[as3] combobox data?

[cintaria]

How do I get the data from a combobox?

[cancerinform]

Here is an example if you want the label:

mc.addItem({label:"item1"});
mc.addItem({label:"item2"});
mc.addItem({label:"item3"});
mc.addEventListener(Event.CHANGE, changeHandler);
function changeHandler(ev:Event):void
{
    trace(ev.currentTarget.selectedItem.label);
}

I don't need the label, I need the data

Then use: trace(ev.currentTarget.selectedItem.data);

It works! Thankyou, thankyou, thankyou!!!
I could hug you. But you're impossible far away from me for a hug
Thanks

... How do I convert the contents of a textfield as an int?

[cintaria]

got it
var number:Number = new Number(txt.text);

The "label" is also data.

I know this is an extremely old thread, but I am trying to do something similar and did not want to start a whole new thread about the same subject, I am trying to get the total amounts from the 4 comboBoxes, into a single text field.

Here is my code so far:

import fl.controls.ComboBox; 
import flash.text.TextField; 
import flash.text.TextFieldType; 

myComboBox.addEventListener(Event.CHANGE, clickHandler); 
myComboBox.addEventListener(Event.CHANGE, totalamount); 
 
var tf:TextField = new TextField(); 
addChild(tf); 
tf1.alwaysShowSelection = true; 

    function clickHandler(event:Event):void {      
        tf1.text = ComboBox(event.target).selectedItem.data; 
}

myComboBox2.addEventListener(Event.CHANGE, clickHandler2); 
myComboBox2.addEventListener(Event.CHANGE, totalamount); 
tf2.alwaysShowSelection = true;

    function clickHandler2(event:Event):void {     
        tf2.text = ComboBox(event.target).selectedItem.data; 
}


myComboBox3.addEventListener(Event.CHANGE, clickHandler3); 
myComboBox3.addEventListener(Event.CHANGE, totalamount); 
tf3.alwaysShowSelection = true;

    function clickHandler3(event:Event):void {     
        tf3.text = ComboBox(event.target).selectedItem.data; 
}


myComboBox4.addEventListener(Event.CHANGE, clickHandler4); 
myComboBox4.addEventListener(Event.CHANGE, totalamount); 
tf4.alwaysShowSelection = true;

    function clickHandler4(event:Event):void {     
        tf4.text = ComboBox(event.target).selectedItem.data; 
}

function totalamount(event:Event):void {
        
        total.text = tf1.text + tf2.text + tf3.text + tf4.text; 
        total.alwaysShowSelection = true;
}

Now, what I have works to get the data, but as you can see, it just adds the text fields and doesn't really do any math to calculate a total amount. I am just learning AS3, from AS2, and I've having a bugger of a time getting it, AS2 was hard enough for me. I'm a designer, not a programmer, but I gotta learn this stuff. Any help is greatly appreciated! Thanks!

when you get the .text of a textfield, you're getting a string. Using + between strings concatenates them, it doesn't add them as numbers. You need to cast them to Number or int.

Change the second to last line of your code to

total.text = String(Number(tf1.text) + Number(tf2.text) + Number(tf3.text) + Number(tf4.text));

Thank you for the response, I changed the code, but I get "NaN" in my totals text field now

EDIT**
I got the NAN to go away, basically it was because I had a $ sign in my data field in the ComboBox. But I have another question, if you don't mind- when my totals are added up, i sometimes get 4 or 5 digits behind the decimal (e.g. 35.49999), how can i limit the total to just be, 35.49?

Thanks!!
