Prototype "extending" my array problem.

I have the following code

Code:

<html>
<head>
<script type="text/javascript" src="cropper/lib/prototype.js" language="javascript"></script>
<script>

function showArray(inArray)
{
   var retString="";
   for(var item in inArray)
   {
      retString+=inArray[item];
   }
   return retString;
}

function arrayTester()
{
   testArray=new Array();
   testArray["val1"]="Value 1";
   testArray["val2"]="value 2";
   outputString=showArray(testArray);
   document.getElementById("output").innerHTML=outputString;
}

</script>
</head>
<body>
<div id="output"></div>
<script>arrayTester();</script>
</body>
</html>

When it executes it outputs tons and tons of prototype garbage in addition to my array. Apparently prototype "extends" any array that is created. Is there any way to stop this from happening?

What browser are you using? It works for me in IE6.

maybe i just don't use arrays enough in JS, but shouldn't "val1" and "val2" be numbers or variables? I know what you have works (in IE 6 at least) but i've just not seen that done before.

Only use an array if you want numerical indexes.

For an associative array, use an object.

Code:

   var testArray=new Object();

The language attribute of the <script> element is deprecated. Just use the type attribute.
