Notify panel similar to stackoverflow's

Asked 2008-12-14T19:10:02.580

Remember the little div that shows up at the top of the page to notify us of things (like new badges)?

I would like to implement something like that as well and am looking for some best practices or patterns.

My site is an ASP.NET MVC app as well. Ideally the answers would include specifics like "put this in the master page" and "do this in the controllers".

Just to save you from having to look yourself, this is the code I see from the welcome message you get when not logged in at stackoverflow.

<div class="notify" style="">
  <span>
    First time at Stack Overflow? Check out the
    <a href="/messages/mark-as-read?returnurl=%2ffaq">FAQ</a>!
  </span>
  <a class="close-notify" onclick="notify.close(true)" title="dismiss this notification">×</a>
</div>

<script type="text/javascript">

  $().ready(function() {
    notify.show();
  });

</script>

I'd like to add that I understand this perfectly and also understand the jquery involvement. I'm just interested in who puts the code into the markup and when ("who" as in which entities within an ASP.NET MVC app).

Thanks!

This answer has a complete solution.

Copy-pasting:

This is the markup, initially hidden so we can fade it in:

<div id='message' style="display: none;">
    <span>Hey, This is my Message.</span>
    <a href="#" class="close-notify">X</a>
</div>

Here are the styles applied:

#message {
    font-family:Arial,Helvetica,sans-serif;
    position:fixed;
    top:0px;
    left:0px;
    width:100%;
    z-index:105;
    text-align:center;
    font-weight:bold;
    font-size:100%;
    color:white;
    padding:10px 0px 10px 0px;
    background-color:#8E1609;
}

#message span {
    text-align: center;
    width: 95%;
    float:left;
}

.close-notify {
    white-space: nowrap;
    float:right;
    margin-right:10px;
    color:#fff;
    text-decoration:none;
    border:2px #fff solid;
    padding-left:3px;
    padding-right:3px
}

.close-notify a {
    color: #fff;
}

And this is javascript (using jQuery):

$(document).ready(function() {
    $("#message").fadeIn("slow");
    $("#message a.close-notify").click(function() {
        $("#message").fadeOut("slow");
        return false;
    });
});

And voila. Depending on your page setup you might also want to edit the body margin-top on display.

Here is a demo of it in action.

I see the following jQuery function? I beleive that injects the html into the div with id notify-container.

I don't understand how this JS is used and called based on certain events, perhaps someone can explain.

var notify = function() {
var d = false;
var e = 0;
var c = -1;
var f = "m";
var a = function(h) {
    if (!d) {
        $("#notify-container").append('<table id="notify-table"></table>');
        d = true
    }
    var g = "<tr" + (h.messageTypeId ? ' id="notify-' + h.messageTypeId + '"' : "");
    g += ' class="notify" style="display:none"><td class="notify">' + h.text;
    if (h.showProfile) {
        var i = escape("/users/" + h.userId);
        g += ' See your <a href="/messages/mark-as-read?messagetypeid=' + h.messageTypeId + "&returnurl=" + i + '">profile</a>.'
    }
    g += '</td><td class="notify-close"><a title="dismiss this notification" onclick="notify.close(';
    g += (h.messageTypeId ? h.messageTypeId : "") + ')">&times;</a></td></tr>';
    $("#notify-table").append(g)
};
var b = function() {
    $.cookie("m", "-1", {
        expires: 90,
        path: "/"
    })
};
return {
    showFirstTime: function() {
        if ($.cookie("new")) {
            $.cookie("new", "0", {
                expires: -1,
                path: "/"
            });
            b()
        }
        if ($.cookie("m")) {
            return
        }
        $("body").css("margin-top", "2.5em");
        a({
            messageTypeId: c,
            text: 'First time here? Check out the <a onclick="notify.closeFirstTime()">FAQ</a>!'
        });
        $(".notify").fadeIn("slow")
    },
    showMessages: function(g) {
        for (var h = 0; h < g.length; h++) {
            a(g[h])
        }
        $(".notify").fadeIn("slow");
        e = g.length
    },
    show: function(g) {
        $("body").css("margin-top", "2.5em");
        a({
            tex

                        StackOverflow uses jQuery - the JS code you posted from SO is a jQuery call. It'll do exactly what you want with almost no code. Highly recommended.
