jquery: Flash messages

Question

With jQuery, how can I display a flash message at the top of the page in an easy way? Is there something built-in, or a plugin, or is it easy enough to do it yourself?

I just added this to my page, displays a loading indicator for each ajax call (no matter where it is on the page)

/* Ajax methods */
/* show the message that data is loading on every ajax call */
var loadingMessage = 'Please wait loading data for page...';
$(function()
{
    $("#AjaxStatus")
    .bind("ajaxSend", function()
    {
        $(this).text(loadingMessage);
        $(this).show();
    })
    .bind("ajaxComplete", function()
    {
        $(this).hide();
    });
});

And the status:

OK, based on your most recent comment, how about this option default message, or complex:

ShowStatus(true, 'Save Failed with unknown Error', 4000);

/* show message for interval */
var saveMessageText = 'Saving...';
function ShowStatus(saveMessage, message, timeInMilliseconds)
{
    var errorMessage = $("#Errorstatus");
    if (saveMessage)
    {
        errorMessage.show();
        var myInterval = window.setInterval(function()
        {
            message = message + '...';
            errorMessage.text(message);
            errorMessage.show();
        }, 1000);
        window.setTimeout(function()
        {
            clearInterval(myInterval);
            errorMessage.hide();
        }, timeInMilliseconds);
    }
    else
    {
        errorMessage.text(message);
        errorMessage.show();
        window.setTimeout('$("#Errorstatus").hide()', timeInMilliseconds);
    };
};

Snip from jquery ajax:

   success: function(msg)
    {
        ShowStatus(true, 'Hey it went well', 4000);
        Process(msg);
    },

  failure: function(msg)
    {
        ShowStatus(true, 'Save Failed with unknown Error', 4000);
    }
