Introduction
When you want to alert the user in the client side of a web application, probably you are embarrassed 
(or you don't give a damn) when you use JavaScript built-in alerts. I know I do. JavaScript built-in alerts are very ugly IMHO and therefore I try to use alternatives instead. In this post, I'll show a very useful alternative that I've been using lately in more then one project – the jQuery Alert Dialogs plug-in.
jQuery Alert Dialogs Plug-in
One of the benefits of using jQuery is the amount of jQuery plug-ins that exist in jQuery eco-system. But the amount of plug-ins also makes it very difficult to find your desired plug-in for each behavior you need. One of the plug-ins I'm using frequently is the jQuery Alert Dialogs. The plug-in “aims to replace the basic functionality provided by the standard JavaScript alert(), confirm(), and prompt() functions”. The plug-in also simulates the use of these standard functions and also gives you the power to create your own style.
How to Use the Plug-in?
First, you will have to download the plug-in from this link – jQuery Alert Dialogs. Also you will have to download jQuery UI Draggable plug-in which the plug-in has dependency on it (or download the entire jQuery UI package like I did). After you download all the relevant scripts, you will have to add the plug-ins to your web application. Here is how my sample solution was ordered:
In the default page, I've added the following links in the head section:
<head runat="server">
<title></title>
<script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.8.5.custom.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.alerts.js" type="text/javascript"></script>
<link href="Content/Style/jquery.alerts.css" rel="stylesheet" type="text/css" />
</head>
Now, you will be able to use the plug-in included methods:
jAlert(message, [title, callback]) – creates an alert. jConfirm(message, [title, callback]) – creates a confirm alert which handles the confirmation in the callback function you supply. jPrompt(message, [value, title, callback]) – creates a prompt alert which handles the value of the user type in the callback function you supply.
The following example shows how to use the alert and prompt:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Defualt.aspx.cs"
Inherits="WebApplication6.Defualt" %>

<head runat="server">

<script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.8.5.custom.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.alerts.js" type="text/javascript"></script>
<link href="Content/Style/jquery.alerts.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(document).ready(function () {
$("#btnAlert").click(function () {
jAlert('Pushed the alert button', 'Alert Dialog');
});
$("#btnPrompt").click(function () {
jPrompt('Type some value:', '', 'Prompt Dialog', function (typedValue) {
if (typedValue) {
jAlert('You typed the following ' + typedValue);
}
});
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="button" value="Alert Me" id="btnAlert" />
<input type="button" value="Prompt Me" id="btnPrompt" />
</div>
</form>
</body>
</html>
and the output of pushing the prompt button:
Summary
The jQuery Alert Dialogs plug-in is a very useful plug-in. Avoid using the built-in alerts and start using a more styled and beautiful alerts. If the supplied style isn't good for your needs, then customize it and make it more suitable.
