getting an array into listbox component...

[barrowman]

HIi

I know how to get an external txt file into the listbox component...

myData = new LoadVars ();
myData.onLoad = AddItems;
myData.load ("ComboBox_Text_Link2.txt");
//----------------------

function AddItems() {
    
    for (i=0; i<5; i++) {
            var Name       = eval("myData.Name"+i);
            
            var DataProvider = { Link:Name}; 
      dropDown.addItem(Name, DataProvider); 
    }
    dropDown.setChangeHandler("SelectItem");
}

But what if I have an array

dArray = ["item0" , "item1" , "item2" , "item3" , "item4"];

How could I get that into the component list box...

thanks in advance...

If your listbox is called myList, then

dArray = ["item0" , "item1" , "item2" , "item3" , "item4"];
for (var item in dArray) myList.addItem(dArray[item]);

will fill it. Then you can fill it on (press) or anything else...

Here is what I've narrowed it down to...

dArray = ["item0" , "item1" , "item2" , "item3" , "item4"];

function AddItems() {
for (i=0; i<5; i++) {
dropDown.setDataProvider(dArray);
}
dropDown.setChangeHandler("SelectItem");
}

function SelectItem(){
trace (dropDown.getSelectedItem().dArray[1]); // this should return the same value as the drop down selected
}

But I want it to be able to trace the value via the select item...

Howdy...

Haven't tried DataProvider myself... But I know that pom's code work... That's how I have used to populate the listbox before...

[barrowman]

thanks but I'm not entirely sure how to implement that code with the rest of it. ie how I could trace what happens when I select something...

dArray = ["item0" , "item1" , "item2" , "item3" , "item4"]; 

function AddItems() 
{ 
  for (i=0; i<5; i++) 
  { 
    dropDown.addItem(dArray[i]); 
  } 
  dropDown.setChangeHandler("SelectItem"); 
} 

function SelectItem()
{ 
  trace (dropDown.getSelectedItem().label);
}

Try this and see if it works...

[barrowman]

no doesn't seem to be loading the array into dropDown...??? :-(

Oh... I see what's missing...

Put

AddItems();

at the end of the code, and drag the listbox from the component library and name it 'dropDown'... I just tested it and it worked just fine...
