sort multiple arrays?

[podenphant]

Hi All

I have a long list off arrays i need to sort using one off the arrays as sort of a key. I'm using it as a kind of address-database

_level0.arrTelefon
_level0.arrTelefax
_level0.arrName

Right now all data is sorted in different arrays with
"_level0.arrTelefon" as the 'key'.

How can I rearrange the arrays - using the alphabetical order in array "_level0.arrName" as a key?

Regards

you can sort an array using a function to determine the sort sequence for example you could have an array of objects;

arr = [ { name: "bill", age: 21}, {name: "jim", age: 18 }, { name: "pam", age: 24 }, { name: "jill", age 19 } ];

then you can sort that array using the sort function;

arr.sort(mySequence);

where mySequence is a function defined by you that is passed two elements of the array. the function deterimines the order of the elements it is passed and returns the value;
-1 if A appears before B in the sorted sequence
0 if A = B
1 if A appears after B in the sorted sequence

function mySequence(a, b) {
   if (a.age > b.age)
     return(-1)
   else
   if (a.age < b.age)
     return(1);
   return(0);
}

this should sort the array in descending sequence based on the persons age.
hope this helps

You can make an array of object to combine 3 array together. After sort that array, then you break them apart into 3 arrays.

Or you can make a temporal array of "index"; Then sort the index to get sequence and create 3 new array according to this new sequence of index.

_level0.arrTelefon = ["040", "080", "060"];
_level0.arrTelefax = ["T", "V", "U"];
_level0.arrName = ["A", "C", "B"];
temp = [];
for (var p = 0; p<arrName.length; p++) {
	temp[p] = p;
}
function order(a, b) {
	if (arrName[a]>arrName[b ]) {
		return 1;
	}
}
temp.sort(order);
arr1 = [];
arr2 = [];
arr3 = [];
for (var k = 0; k<temp.length; k++) {
	var index = temp[k];
	arr1[k] = arrName[index];
	arr2[k] = arrTelefon[index];
	arr3[k] = arrTelefax[index];
}
arrName = arr1;
arrTelefon = arr2;
arrTelefax = arr3;
trace(arrName);
trace(arrTelefon);
trace(arrTelefax);

thx for the code ericlin

however there are some syntax problems that I can't figure out ... could you help out?

[ericlin]

I dont know how to fix the display.

Try:
click "Reply w/Quote"; Then the content of the post will be quoted in the white edit box. There you can see and copy the raw codes.

Thx ericlin, works like a dream

since we're at it ...

for a highscore I have a long list of arrays containing "name" "score" and "email"

player1 ["pl1",520,"[email protected]"]
player2 ["pl2",120,"[email protected]"]
player3 ["pl3",100,"[email protected]"]
player4 ["pl4",900,"[email protected]"]

How can I sort and list each array by score? And list X number of players?
Score 1
Score 2
... and so on

[ericlin]

//show the first 2 highest score data
player1 = ["pl1", 520, "[email protected]"];
player2 = ["pl2", 120, "[email protected]"];
player3 = ["pl3", 100, "[email protected]"];
player4 = ["pl4", 900, "[email protected]"];
list = [];
for (var p in _root) {
	var arr = _root[p];
	if ((typeof (arr) == "object") && (p.indexOf("player")>=0)) {
		list.push(arr);
	}
}
function order(a, b) {
	if (a[1]<b[1]) {
		return 1;
	}
}
list.sort(order);
X = 2;
for (var k = 0; k<X; k++) {
	trace(list[k]);
}
