jQuery Ready code not executing

I have the following code in my _Layout.cshtml, targeted at a view once removed, through a layout nested one level below _Layout.cshtml.

<title>@ViewBag.PageTitle</title>
<link rel="icon" type="image/png" href="@Url.Content("~/Images/favicon.png")" />
<link rel="stylesheet" type="text/css" href="@Url.Content("~/Content/Blueprint/screen.css")" media="screen, projection" />
<link rel="stylesheet" type="text/css" href="@Url.Content("~/Content/Blueprint/print.css")" media="print" />
@Html.Telerik().StyleSheetRegistrar().DefaultGroup(group => group.Add("telerik.common.css").Add("telerik.simple.css"))
@RenderSection("MainBodyStyling", false)
<script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript">开发者_开发百科;</script>
<script type="text/javascript">
    $(document).ready(function () {
        debugger;
        //$("iframe").width($("iframe").contents().find("table").width());
    });
</script>

I cannot get the jQuery code to execute, in Chrome or Firefox 5.0, even just the debugger call. This is with jQuery 1.4.4, inside an MVC3 project. The code works when I paste it into both Firebug and Chrome JS consoles, so I know the code itself is not at fault.

CORRECTION: I added the erroneous document with quotes as a last ditch attempt. I had tried my default (I'm quite used to working with jQuery), $(function () { syntax, with no difference. The real problem is not my syntax, but correct code not executing. I have removed the quotes with no difference at all.

ADDENDUM: If I put a breakpoint on the debugger line, the code stops at the breakpoint in the Chrome console. I have no idea what this is about.

Don't use quotes around document.

$(document).ready(function () { });

or better yet, just pass your handler function directly into the jQuery method (its an alias for ready):

$(function () { });

document should be without quotes:

$(document).ready(function() {
    debugger;
});

Put your scripts at the bottom of the document just before the closing body tag. This is non blocking and avoids any need for doc ready blocks. Double win.

Further reading from Yahoo and here by Dave Ward.

You have a string "document" in the selector it needs to be the document object

$(document).ready();

as already stated, document shouldn't have quotes. To avoid this, you can do

$(function() {
    debugger;
});

instead to define a ready callback

jquery-1.4.4.min.js is not included in the scripts folder, so it can not be used.

I have replaced it with jquery-1.5.1.min.js and the problem was solved.
