SCRIPT5009: 'JSON' is undefined in IE 10 The value of the property '$' is null or undefined, not a Function object

   <!DOCTYPE html>

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title>Hello World</title>
        <link href="StyleSheet.css" type="text/css" rel="stylesheet" />
        <script type="text/javascript" src="Scripts/jquery-2.0.3.js">
            $(document).ready(function () {

                <%--$("#width").val() = $(window).width();
                $("#height").val() = $(window).height();--%>


            });
    </script>
        <script type="text/javascript">
            $(document).ready(function () {
                $("#width").val($(window).width());
                $("#height").val($(window).height());
            });
        </script>
    </head>
<body>
    <form id="form1" runat="server">
<input id="width" type="hidden" runat="server" />
        <input id="height" type="hidden" runat="server" />
</form>
</body>
</html>

the above is my aspx code with jquery script which gives the window height and width.

this code perfectly fine on all the browsers when i run the web app from visual studio http://localhost/Mypage.aspx

but when i host it on iis and run with my machine name http://MyMachine/Mypage.aspx it gives JSON undefined and the Property "$" is null or undefined errors.( this is only in IE 10 (non-compatibility mode) , for chrome it works fine)

question 1) do we need to take care of any security constraints for IE 10?

question 2) why does it happen this way when i host it on iis and run it with machine name on my own machine?

question 3) am i missing any jquery refrence.

question 4) obvious one, any solution to this problem.

use the Meta tag as suggested by many of the people.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

but I want to give an importatnt tip. the mata tag should be the first tag in the head tag. I have read it some where if it is not the first tag it would not have its effect.

as suggested by I4v, adding this to the header fixed the bug for me too:

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Thanks guys

Are you sure you have the Scripts folder with jquery in the server? I suggest you to debug with fiddler and see if jquery is loaded correctly or if there is an http error.
