    </div>
        <script src="Scripts/jquery.min.js" type="text/javascript"></script>
        <script type="text/javascript">
        
        var objDiv = document.getElementById("cont");
        objDiv.scrollTop = objDiv.scrollHeight;
        function updateDiv() {
            $("#here").load(window.location.href + " #here");
        }

m new to Javascript and jQuery. I want to click a button and have a js function executed. (For this example, it's just an alert, but it's actually an ajax function.)

The first alert appears, but after I click the button, I never see the second ("did it") alert. It looks like javascript doesn't think the doIt() function is defined when the button is clicked.

Here's the relevant code:

$(document).ready(function()
{ 
    alert('ready');

    function doIt() {
        alert('did it');
    };
}
)

<body>
    <input name="Go" type="button" value="Go" onclick="doIt();"/>
</body>
