Array sort/ size reduction

[scudsucker]

Hi- in making an XML text "search engine" I've run into a problem which I cannot solve. No matter how much I puzzle over it I am stuck in the same rut. I really need a good hard kick to get me out.

Let me simplify:

With

code:

---

var aTemp=new Array();

aTemp[0]="A";

aTemp[1]="B";

aTemp[2]="C";

aTemp[3]="A";

aTemp[4]="A";

---

I would like to get from this another array, with values

code:

---

aFinal[0]="A"

aFinal[1]="B"

aFinal[2]="C"

---

I cannot work out how to do it though... Thanks for any hints

hello.
I'm not totally sure what you're getting at, but if it's that you want to eliminate repetition in the final array, i think this should do it:

code:

---

var aTemp = new Array();

aTemp[0] = "A";

aTemp[1] = "B";

aTemp[2] = "C";

aTemp[3] = "A";

aTemp[4] = "A";

aTemp[5] = "A";

aTemp[6] = "C";

var aFinal = new Array();

aFinal.push("x");// Just to get it going. There's probably a better way to do it.

function loopTemp()

{

	for (var i in aTemp)

	{

		elemTemp = aTemp[i];

		loopFinal(elemTemp);

	}

}

function loopFinal(element)

{

	for (var j in aFinal)

	{

		if (aFinal[j] == element)

		{

			return;

		}

	}

	aFinal.push(element);

	return;

}

loopTemp();

aFinal.splice(0,1);// Remove that 'x'!

aFinal.sort();// Not really necessary.
