eval is your friend (using the word friend in its loosest form :) 
<script language="javascript">
    var arr = new Array('one','two');
    var lb = "\x5B";
    var rb = "\x5D" 
    var code =  "alert(\"Second element is \"+arr"+lb+"1"+rb+")";
    eval(code);
</script>

    This might be simpler: 
    // Hack around mangling of left square bracket by PerlMonks.

function get_item(a, i) {
   return eval("a\x5Bi]");
}

function set_item(a, i, v) {
   return eval("a\x5Bi] = v");
}

    [download]
    Usage: 
    var a = new Array(5);
set_item(a, 2, "Hello World\n");
alert(get_item(a, 2));

    Update: Never mind. New useful escapes documented here.
