I don't have my computer with me so I can't provide an example but @Html.ValidationSummary() return a unorderd list of errors. (see http://msdn.microsoft.com/en-us/library/dd460343(v=vs.108).aspx )

You could check if @Html.ValidationSummary() has a value in JavaScript and then use JQuery to pull out the text values of the <li> elements and put them in an alert.

Try this, I haven't tested it yet but it should be a guide:

<script>
var validationSummary = '@Html.ValidationSummary()';
var alerttext = '';
if (validationSummary !== '')
{
    $(validationSummary)
        .find('li').each( function()
        {
            alerttext = alerttext + $(this).text() + '\n';
        });

    alert(alerttext);

}

</script>
