Arrays 1

[Brian56]

Hi,

I have an array that is initially populated from a database. The user can also search the database and this will lead to the array being updated.

Everythings works fine up to this point except that the array can now contain duplicate values. I need to check the array for duplicate values and if a dupicate is found it must be deleted as otherwise this can sometimes and unpredictably cause the wrong information to be displayed.

I haved searched the actionscript dictionary and cannot find a command that will let me do this.

Can someone please point me down the road I need to go?

There's nothing built in to the array object but this script will do what you're after:

testArray = [12, 34, 56, 78, 90, 43, 43, 65, 87, 98, 32, 12, 44, 90, 63];
//
trace('initial array values '+testArray);
//
for (init=0; init<testArray.length; init++) {
	for (i=init+1; i<testArray.length; i++) {
		if (testArray[init] == testArray[i]) {
			trace(&quot;duplicate number found: &quot;+testArray[i]);
			testArray.splice(i, 1);
		}
	}
}
//
trace('final array values '+testArray);
