Reading arrays that are not in sequence

programming flash
1

I have a text file that looks like this:

day|&day0&date0=07/01/2003&bn0=We Rock This Town&
day|&day1&date1=07/02/2003&bn1=Rocketsl&
day|&day3&date3=07/05/2003&bn3=Rockers&
day|&day4&date4=07/05/2003&bn4=Hip Hop&


home = new LoadVars();
homeURL = "the text file"
home.load(homeURL);
home.onLoad = function(success) {
	if (success) {
	myArray = new Array();
	for (i=0; i-1<this.NUMITEMS; i++) {
		var date = eval("this.date"+i);
		var name = eval("this.bn"+i);
		myArray* = [date, name];
var DataProvider = {date:myArray*[0], bn:myArray*[1]}
	pullDay.addItem(myArray*[0], DataProvider);

Now when I run this code, the listbox I am populating with the array information looks like this:

07/01/2003
07/02/2003
object object
object object

As you can see since I am not following a 1,2,3,4,5 order in the array, flash does not know what to do with the rest of the data. Is there a way around this?

The for loop looks like it’s assigning information into your array and probably setting position 2 to undefined as there is no matching data in the text file, so prior to pulling the information into your listbox check to see if it’s valid.

Hope this helps

Yes, it helps because I think what you are saying can work but I don’t have any ideas on how to go about doing that.

Anyone got any bullets?

Take a shot.

Try something like this…

[AS]
for (i=0; i-1<this.NUMITEMS; i++) {
var date = eval(“this.date”+i);
var name = eval(“this.bn”+i);
myArray* = [date, name];
if((myArray*[0] != undefined) && (myArray*[1] != undefined)) {
var DataProvider = {date:myArray*[0], bn:myArray*[1]}
pullDay.addItem(myArray*[0], DataProvider);
}

[/AS]

I ended up doing it this way off of your code:


 for (i=0; i-1<this.NUMITEMS; i++) {
             var date = eval("this.date"+i);
             var name = eval("this.bn"+i);
             if(date != undefined){
             myArray* = [date, name];
             var DataProvider = {date:myArray*[0], bn:myArray*[1]}
                           pullDay.addItem(myArray*[0], DataProvider);

I set my NUMITEMS to 31 because I am working with days of the month. So the code above loops through 1-31 and only shows the days that are in the array file.

Sweet!!
