Sorting a new array from an existing array

[Ozeona]

Hi

i got an existing array, main[y], which after an equation, will come out with another array.

Code: Select all

 if (main[y] === topicList.getValue()){
        subTopic = [];
        subTopic = fTitle[y]
        trace(subTopic)
}

However, i could not sort the subTopic, as it keep giving me undefined. Is there any way to sort this subTopic, such that they are in alphabetical orders?

Appreciate any help.

You're not actually properly defining your arrays, from the code I can see.

You're also not using arrays properly.

You define an array like this:
myArray = new Array();

then add elements:
myArray[0] = "hello";
etc, etc.

So here's your code, with some defined variables which works...

Code: Select all

main = new Array();
main[0] = "one";
main[1] = "two";
main[2] = "three";

topicList = "two";
y = 1;

if (main[y] == topicList)
{ 
        subTopic = new Array(); 
        subTopic[0] = main[y];
        trace(subTopic) 
}

I'm not entirely sure what you're trying to accomplish so my code doesn't really do much, but it should point you in the right direction.

sorry abt the hasty codes. Actually it is a dynamic array( taken from xml) therefore i could not define it as indicated.

im trying to get the first label's content of the sub list box(featureList) out using the top listbox (topicList)

these are some of the main codes that are related to this issue.. Hope these codes can be understood

Code: Select all

 ////////////////////////////////////////////////////input items in topic listbox 
function setupTopicList() {
	topicList.setAutoHideScrollBar(true);
	f_Topic.reverse();
	sampleList._visible = false;

 for(var item in f_Topic){
	topicList.addItem(f_Topic[item]);
}
topicList.sortItems(upperCaseFunc);
function upperCaseFunc(a,b){
return a.label.toUpperCase() > b.label.toUpperCase();
}
}

////////////////////////////////////////////////////////// input items in feature listbox
function setupFeatureList(p) {
featureList.setAutoHideScrollBar(true);
all = counting.length
featureList.removeAll();
featureList._visible = false;
featureList.setStyle("backgroundColor", "0xC0DFF1");
for(m=0; m<all; m++) {
	if(f_TopicR[p] === fTopic[m]) {  
		featureList._visible = true;
		featureList.addItem(fTitle[m]);
//trace("m of featureList = " + m)
}
}

featureList.sortItems(upperCaseFunc);
function upperCaseFunc(a,b){
return a.label.toUpperCase() > b.label.toUpperCase();
}
}


/////////////////////////// trying to use the topiclist to show 1st of features

function goToFirst(t) {
	if (loaded == filesize) {
		countingall = counting.length
	for( y =0; y < countingall; y++) {
	if (t == fTopic[y]){
		
trace(fTitle[y])
x = y

picture.loadMovie = image[y]; 
titleText.text = description[y];

}}
}

////////////////////////////////////////////////////////////topic list listener
myTopicBoxListener = new Object();
myTopicBoxListener.change = function ( eventObj ){
	var eventSource = eventObj.target;
	var selectedObj = eventSource.selectedItem;
	var q = eventSource.selectedIndex;
	var selectedObjLabel = selectedObj.label;
	var t = eventSource.selectedItem.label;
setupFeatureList(q);
goToFirst(t);


}

topicList.addEventListener ("change", myTopicBoxListener);


///////////////////////////////listens to the feature listbox for command

myListBoxListener = new Object();
myListBoxListener.change = function ( eventObj ){
	var eventSource = eventObj.target;
	var selectedObj = eventSource.selectedItem;
	var p = eventSource.selectedIndex;
	var selectedObjLabel = selectedObj.label;
	var r = eventSource.selectedItem.label;
