for ... in statement and order in Chrome

[Techi602]

var x;
var mycars = new Array();
mycars[3] = "Saab";
mycars[1] = "Volvo";
mycars[0] = "BMW";

for (x in mycars)
{
document.write(mycars[x] + "<br />");
}

all major browsers (IE, FF, O, S) sort items by the order when the item was added into array (Saab, VOlvo, BMW)

however Chrome sorts items by their index (BMW, Volvo, Saab)

Therefore there can be iregularities on website, while processing some JSON data and items are displayed in different order

how to fix this in Chrome? I have my data (array) in JSON and i need to display it (with index) in given order...

Hi

all major browsers (IE, FF, O, S) sort items by the order when the item was added into array (Saab, VOlvo, BMW)

Sometimes. Other times is differently. Personally I got :
[ul]
[li]BMW, Volvo, Saab : FireFox, Midori, Konqueror[/li]
[li]Saab, Volvo, BMW : SeaMonkey, Epiphany, Galeon, Opera[/li]
[/ul]

Iterates a specified variable over all the properties of an object, in arbitrary order.

( Mozilla Developer Center | for...in )

The conclusion : if the order matters, do not use [tt]for[/tt] .. [tt]in[/tt].
