Has anyone played with this funtionality.

i want to use a combo box, so when a user selects a choice from the list, it then executes some code.

i dont really understand what they say in the help.

here is some example code;

code:

toyList.setChangeHandler("myHandler");
function myHandler(component){
   trace(toyList.getSelectedItem().label); 
} 

however, where should i put this code. on the actual component, if i do then i need an OnClipEvent.

im lost on this.

it sounds like it should be within an if/else statement that is checking the value of what is selected and then changing the handler set in the parameters of the combo box based on what selection has been made.

do the users have to hit a button to confirm their selection? if so, this statement would go on the button. am i understanding your question correctly?

well,

not really, i figured it out.....you have to write a function, and then in your component properties reference that function call.

i have it working, now im trying to make 2 boxes work dependently,

ie, select an album name, which in turn populates box 2 with the correct song names to select.....

im almost there..just NOT quite right.

thanks though

actually, im updating my MP3 player.

ck it out.
its NOT 100% fixed yet. but it will be!

here is the code i used:
2 combo boxes
Droppy and Song_Names (i know dumb names)


i created an action on frame 1 with this code.

code:

song_names.setSelectedIndex(null);
song_names.setEnabled(false);
droppy.setStyleProperty("arrow", 0xFF0000);
// set up album selection
function onSelectAll(droppy) {
	if (droppy.getSelectedIndex()>1) {
		trace(droppy.getSelectedIndex());
		song_names.setEnabled(true);
		song_names.removeAll();
		song_names.setSelectedIndex(0);
		_root.outline.album = droppy.getValue();

		// set up song titles

		if (droppy.getSelectedIndex() == 2) {
			// Buddah Album
			song_names.removeAll();
			song_names.addItem("Carosel", 1);
			song_names.addItem("blah", 2);
			song_names.addItem("blah2", 3);
			song_names.addItem("blah3", 4);
			song_names.addItem("blah4", 5);
			song_names.addItem("blah5", 6);
			song_names.addItem("blah6", 7);
			song_names.addItem("blah7", 8);
			song_names.addItem("blah8", 9);
		}
		
		if (droppy.getSelectedIndex() == 3) {
			// Cheshire Album
			song_names.removeAll();
			song_names.addItem("Tony", 1);
			song_names.addItem("blah", 2);
			song_names.addItem("blah2", 3);
			song_names.addItem("blah3", 4);
			song_names.addItem("blah4", 5);
			song_names.addItem("blah5", 6);
			song_names.addItem("blah6", 7);
			song_names.addItem("blah7", 8);
			song_names.addItem("blah8", 9);
		}

	
	} else {
		song_names.setSelectedIndex(null);
		song_names.setEnabled(false);
	}
}

	// Play a song
function onPlaySong(song_names) {
	if (song_names.getSelected()>=0) {
		unloadMovieNum(1);
		_root.outline.album = droppy.getSelectedItem().data;
		trace(_root.outline.album);
		_root.outline.songnum = (song_names.getSelectedIndex()+1);
		trace(_root.outline.songnum);
		_root.outline.totalsongs = int(13);
		filename = (_root.outline.album+songnum);
		if (_root.outline.pause.paused == false) {
			loadMovieNum("http://www.kowalick.net/"+filename+".swf", 1);
			_root.outline.spectrum.gotoAndPlay(2);
		}
	}
}

The best way to write a change Handler, that i have experienced so far is to write it similar to this:

testObj = new Object();
testObj.testHandler = function(){
//place code here
}

whateverObject.setChangeHandler("testHandler", testObj);


Just thought i would try and contribute.
