ASP.NET, CSS and jQuery

Question

I have this aspx page:

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Some Title</title>
    <link href="css/home.css" rel="stylesheet" />
    <script src="js/jQuery.js"></script>
    <script src="js/dragBar.js"></script>
</head>
<body>
<div id="content">
    <div id="map">
        <iframe frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.co.za/maps/ms?msa=0&amp;msid=208869092274662645717.0004dd2a2065f7b179e5b&amp;hl=en&amp;ie=UTF8&amp;ll=-25.401819,28.721652&amp;spn=0,0&amp;t=m&amp;output=embed">
        </iframe>
        <div id="dragbar"></div>
    </div>
    <div id="main">
        <asp:Label ID="lblError" runat="server" Text="Label"></asp:Label>
    </div>
</div>

This is my CSS:

#content {
    position: relative;
    height: auto;
    width: 1000px;
    margin: auto;
    padding-top: 150px;
    z-index: 2;
    background-color: white;
    border-left: 1px solid black;
    border-right: 1px solid black;
}

#content iframe {
    position: relative;
    top: 0px;
    left: 0px;
    width: 100%;
    height: 100px;
    min-height: 200px;
    border-bottom: 1px solid black;
    box-shadow: 0px 0px 10px black;
}

#content #main {
    background-color: BurlyWood;
    position: relative;
    width: 1000px;
    height: 200px;
    right: 0;
    left: 0px;
    z-index: 0;
}

#content #map {
    background-color: IndianRed;
    width: 1000px;
    height: auto;
    position: relative;
    top: 0px;
    bottom: 38px;
    overflow-y: hidden;
    z-index: 1;
}

#content #dragbar {
    background-color: black;
    position: absolute;
    bottom: 0px;
    width: 100%;
    height: 3px;
    cursor: row-resize;
    z-index: 1000;
}

And this is my jQuery:

$('#dragbar').mousedown(function (e) {
    e.preventDefault();
    $(document).mousemove(function (e) {
        $('#main').css("top", e.pageY);
        $('#dragbar').css("bottom", 0);
        $('iframe').css("height", e.pageY - 10);
    });
});

$(document).mouseup(function (e) {
    $(document).unbind('mousemove');
});

My problem is that this works on jsFiddle when I type the code, but this is not working in Visual Studio 2012. Is there something I am missing?

Sorry, Forgot about the problem. My problem is that it should resize the map div and the iframe inside it when I drag the dragbar div.

Is this exactly what you have in your asp.net page, because if any of those items you reference by ID are asp.net runat=server controls, their client ID will be different in the browser than the asp.net page and your jquery selectors will not find them. View the source code in your asp.net page in the browser and check! — Neil Trodden

The main difference between jsFiddle and VisualStudio is how the scripts are being included. First, make sure jquery is being loaded correctly (paths are correct etc) by running the script debugger or adding an alert. Second, try wrapping your script in an OnReady handler to make sure everything is finished loading before executing:

$( document ).ready(function() {
    alert("jQuery is working");

    $('#dragbar').mousedown(function (e) {
        e.preventDefault();
        $(document).mousemove(function (e) {
            $('#main').css("top", e.pageY);
            $('#dragbar').css("bottom", 0);
            $('iframe').css("height", e.pageY - 10);
        });
    });

    $(document).mouseup(function (e) {
        $(document).unbind('mousemove');
    });
});
