Eval works on FireFox but not on Google-Chrome

Good day guys.
While doing simple interactive mathematical calculator for my son, i came across some issues. in the beginning i was working on Firefox 4.0.1 Fedora 15 didn’t get any issue yet when i switched for google-chrome 11.0.696.68 the script didn’t work anymore.
i trimmed it down to simplest form possible and here i demonstrate:

[COLOR=”Blue”]
<html>
<body>

<script type=”text/javascript”>

eval(“x=10;y=20;document.write(x*y)”);
document.write(“<br />” + eval(“function(){var loop=’123′;return loop}”)());
document.write(“<br />” + eval(x+17));

</script>

</body>
</html>[/COLOR]

the script should output :
[COLOR=”Blue”]200
123
27 [/COLOR]
yet on chrome it only outputs
[COLOR=”Blue”]200[/COLOR]

much regards for the help

@cluefulMay 28.2011 — If you use Chrome's console you'll see the problem.

If you must use eval, you can do this:
[CODE]document.write("<br />" + eval("(function(){var loop='123';return loop})()") );[/CODE]

@rnd_meMay 31.2011 — statements are greedy but easily coercible into leaky expressions: [CODE]eval("[COLOR="Red"]0||[/COLOR]function(){var loop='123';return loop}")()[/CODE]

Success!
