Error while finding object's index in an array

[onurcan1977]

I've an array with some properties. When I try to find an object's index I'm getting error TypeError: Error #1009. I'm using Flash CS6.

Here's my array:

var squareArr:Object  = {
     a1: {
          piece: wr1_txt,
          pieceLoc: {  
            x: "-3",
            y: "347"
          }
     },
     b1: {
          piece: wn1_txt,
          pieceLoc: {  
            x: "47",
            y: "347"
          }
     },
...

Below code is giving me error #1009 while I want it to return a1:

trace (squareArr.indexOf(wr1_txt));

I tried:

var s:String;
var found:Boolean=false;
for (s in squareArr) {
    if (squareArr[s].piece == wr1_txt) { // YAY found it
        found=true;
        break;
    }
}
if (found) trace(s); else trace("Not found!");

but it says not found

var tempObj:Object = new Object();

var a1:Object = new Object();
a1.piece = "wr1_txt";
tempObj.xLoc = -3;
tempObj.yLoc = 347;
a1.pieceLoc = tempObj;

var b1:Object = new Object();
b1.piece = "wn1_txt";
tempObj = new Object();
tempObj.xLoc = 47;
tempObj.yLoc = 347;
b1.pieceLoc = tempObj;

var squareArr:Array  = new Array();
squareArr = [a1, b1];

var len:int = squareArr.length;

for(var i=0; i<len; i++)
{
	var obj:Object = squareArr[i] as Object;
	
	if(obj.piece == "wn1_txt")
	{
		trace(i);
		break;
	}
}

thanks for the reply. but it doesn't trace a1 or b1.

Hi,

var squareArr:Object = {
    a1:{piece: "wr1_txt",pieceLoc:{x: -3, y: 347}}
    ,
    b1:{piece: "wn1_txt",pieceLoc:{x: 47, y: 347}} 
};

var s:String;
var found:Boolean = false;
for (s in squareArr) {
    if (squareArr[s].piece == "wn1_txt") {
        found = true;
        break;
    }
}
if (found) trace(s); else trace("Not found!");
