jquery visitors flip counter like digital clock

I was visiting a website called stepout.com. I came across this members counter which seem to be cool. So here i explain it for you, how it is done.

Step-1 : We start by adding some jquery plugins and css to our page

 <!-- jQuery from Google CDN, REQUIRED -->
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
    <!-- My flip counter script, REQUIRED -->
    <script type="text/javascript" src="js/flipcounter.min.js"></script>
    <!-- Style sheet for the counter, REQUIRED -->
    <link rel="stylesheet" type="text/css" href="css/counter.css" />

    <!-- jQueryUI from Google CDN, used only for the fancy demo controls, NOT REQUIRED for the counter itself -->
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script>
    <!-- Style sheet for the jQueryUI controls, NOT REQUIRED for the counter itself -->
    <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/themes/vader/jquery-ui.css" />
    <!-- Style sheet for the demo page, NOT REQUIRED for the counter itself -->
    <link rel="stylesheet" type="text/css" href="css/demo.css" />

Step-2 : Next job is to put some div tags where it will be displayed

<li>Increment:
            <span id="inc_value">123</span> <a href="#">[?]</a><div id="inc_slider"></div>
            <div>
                <p>This slider controls the counter increment by using the <b>setIncrement</b> method:</p>
                <code>myCounter.setIncrement(value);</code>
            </div>
        </li>

Step-3 : Our next job is to have some javascript customization

<script type="text/javascript">
    //<![CDATA[

    // Initialize a new counter
    var myCounter = new flipCounter('counter', {value:10000, inc:123, pace:800, auto:true});

    $(function(){

        /**
         * Demo controls
         */

        var smartInc = 0;

        // Increment
        $("#inc_slider").slider({
            range: "max",
            value: 123,
            min: 1,
            max: 1000,
            slide: function( event, ui ) {
                myCounter.setIncrement(ui.value);
                $("#inc_value").text(ui.value);
            }
        });

        // Pace
        $("#pace_slider").slider({
            range: "max",
            value: 800,
            min: 100,
            max: 1000,
            step: 100,
            slide: function( event, ui ) {
                myCounter.setPace(ui.value);
                $("#pace_value").text(ui.value);
            }
        });

        // Auto-increment
        $("#auto_toggle").buttonset();
        $("input[name=auto]").change(function(){
            if ($("#auto1:checked").length == 1){
                $("#counter_step").button({disabled: true});
                $(".auto_off_controls").hide();
                $(".auto_on_controls").show();

                myCounter.setPace($("#pace_slider").slider("value"));
                myCounter.setIncrement($("#inc_slider").slider("value"));
                myCounter.setAuto(true);
            }
            else{
                $("#counter_step").button({disabled: false});
                $(".auto_off_controls").show();
                $(".auto_on_controls").hide();
                $("#add_sub").buttonset();
                $("#set_val, #inc_to, #smart").button();
                myCounter.setAuto(false).stop();
            }
        });
        $("#counter_step").button({disabled: true});
        $("#counter_step").button().click(function(){
            myCounter.step();
            return false;
        });

        // Addition/Subtraction
        $("#add").click(function(){
            myCounter.add(567);
            return false;
        });
        $("#sub").click(function(){
            myCounter.subtract(567);
            return false;
        });

        // Set value
        $("#set_val").click(function(){
            myCounter.setValue(12345);
            return false;
        });

        // Increment to
        $("#inc_to").click(function(){
            myCounter.incrementTo(12345);
            return false;
        });

        // Get value
        $("#smart").click(function(){
            var steps = [12345, 17, 4, 533];

            if (smartInc < 4) runTest();

            function runTest(){
                var newVal = myCounter.getValue() + steps[smartInc];
                myCounter.incrementTo(newVal, 10, 400);
                smartInc++;
                if (smartInc < 4) setTimeout(runTest, 10000);
            }
            $(this).button("disable");
            return false;
        });

        // Expand help
        $("a.expand").click(function(){
            $(this).parent().children(".toggle").slideToggle(200);
            return false;
        });

    });

facebook like red notification simple css technique

While developing my current web project, i came across a requirement which has to be lashed with a notification similar style as facebook.

After puting some effort i found out the following implementation.

    

Here is a explanation of the above implementation using CSS and simple javascript.

The css

<style>

.noti_Container {
position:relative;
border:1px solid blue; /* This is just to show you where the container ends */
width:16px;
height:16px;
cursor: pointer;
}
.noti_bubble {
position:absolute;
top: -8px;
right:-6px;
padding-right:2px;
background-color:red;
color:white;
font-weight:bold;
font-size:0.80em;

border-radius:2px;
box-shadow:1px 1px 1px gray;
}

</style>

The HTML code

<div onclick="return f1();">
<img src="friends.png" style="border:none;"/>
<div id="n1">2</div>
</div>

The small javascript code to add some more functionality

<script>
function f1()
{
document.getElementById("n1").style.visibility='hidden';
}
</script>

The final implementation can be found here at http://fb.walletchange.com/profile.php

Facebook Style Footer Admin Panel

                 

The popularity of social media has been booming in the past few years and Facebook definitely has climbed high to the top of the social network rankings. Facebook has many Ajax driven features and applications that are very impressive, and one of the things I particularly like is the footer admin panel, where it neatly organizes frequently used links and applications.

This week I would like to cover part 1 of how to recreate the Facebook footer admin panel with CSS and jQuery.

Step 1. Wireframe and Tooltip Bubbles – HTML & CSS

Lay out the wireframe of the admin panel using an unordered list for the foundation. The last two list items (Alert Panel & Chat Panel) will have sub-panels nested within them. Since these two panels will float to the right, the order in the markup will be reversed.



Notice that there is a <small> tag nested within the <a> tag, this is how we will achieve our tooltip bubble on the navigation.

HTML

<div id="footpanel">
    <ul id="mainpanel">
        <li><a href="#">Inspiration <small>
        Design Bombs</small></a></li>
        <li><a href="#">View Profile <small>
        View Profile</small></a></li>
        <li><a href="#">Edit Profile <small>
        Edit Profile</small></a></li>
        <li><a href="#">Contacts <small>
        Contacts</small></a></li>
        <li><a href="#">Messages (10) <small>
        Messages</small></a></li>
        <li><a href="#">Play List <small>
        Play List</small></a></li>
        <li><a href="#">Videos <small>
        Videos</small></a></li>
        <li id="alertpanel"><a href="#">
        Alerts</a></li>
        <li id="chatpanel"><a href="#">
        Friends (<strong>18</strong>)</a></li>
    </ul>
</div>

CSS

First start by fixing the panel to the bottom of the viewport.

#footpanel {
	position: fixed;
	bottom: 0; left: 0;
	z-index: 9999;
/*--Keeps the panel on top of all other elements--*/
	background: #e3e2e2;
	border: 1px solid #c3c3c3;
	border-bottom: none;
	width: 94%;
	margin: 0 3%;
}

As you may already know, IE6 does not understand fixed positioning. I stumbled across a tutorial that fixed this problem*.

*html #footpanel { /*--IE6 Hack - Fixed Positioning to the Bottom--*/
	margin-top: -1px;
/*--Prevents IE6 from having an infinity scroll bar - due to 1px border on #footpanel--*/
	position: absolute;
	top:expression(eval(
document.compatMode &&document.compatMode=='CSS1Compat')
?documentElement.scrollTop+(
documentElement.clientHeight-this.clientHeight)
: document.body.scrollTop +(
document.body.clientHeight-this.clientHeight));
}

*Note: Due to heavy loading on the browser, an alternative solution would be to either use an position: absolute; or if the situation/client allows it use display: none; for those with IE6.

Style the unordered list which will be the foundation of this panel.

#footpanel ul {
	padding: 0; margin: 0;
	float: left;
	width: 100%;
	list-style: none;
	border-top: 1px solid #fff;
/*--Gives the bevel feel on the panel--*/
	font-size: 1.1em;
}
#footpanel ul li{
	padding: 0; margin: 0;
	float: left;
	position: relative;
}
#footpanel ul li a{
	padding: 5px;
	float: left;
	text-indent: -9999px;
/*--For text replacement - Shove text off of the page--*/
	height: 16px; width: 16px;
	text-decoration: none;
	color: #333;
	position: relative;
}
html #footpanel ul li a:hover{	background-color: #fff; }
html #footpanel ul li a.active {
/*--Active state when sub-panel is open--*/
	background-color: #fff;
	height: 17px;
	margin-top: -2px;
/*--Push it up 2px to attach the active button to sub-panel--*/
	border: 1px solid #555;
	border-top: none;
	z-index: 200;
/*--Keeps the active link on top of the sub-panel--*/
	position: relative;
}

Declare the text replacement for each link.
You can download these great icons by Pinvoke here.

#footpanel a.home{
	background: url(home.png) no-repeat 15px center;
	width: 50px;
	padding-left: 40px;
	border-right: 1px solid #bbb;
	text-indent: 0;
/*--Reset text indent since there will be a
combination of both text and image--*/
}
a.profile{ background: url(user.png)
no-repeat center center;  }
a.editprofile{ background: url(wrench_screwdriver.png)
no-repeat center center; }
a.contacts{ background: url(address_book.png)
no-repeat center center; }
a.messages{ background: url(mail.png)
no-repeat center center; }
a.playlist{ background: url(document_music_playlist.png)
no-repeat center center; }
a.videos{ background: url(film.png)
no-repeat center center; }
a.alerts{ background: url(newspaper.png)
no-repeat center center; }
#footpanel a.chat{
	background: url(balloon.png)
no-repeat 15px center;
	width: 126px;
	border-left: 1px solid #bbb;
	border-right: 1px solid #bbb;
	padding-left: 40px;
	text-indent: 0;
/*--Reset text indent since there will be
a combination of both text and image--*/
}
#footpanel li#chatpanel, #footpanel li#alertpanel {
 float: right; }
/*--Right align the chat and alert panels--*/

Style the tooltip bubble, by default the <small> tag will be hidden with a display:none;. On hover over, allow the tooltip to appear with a display:block;

#footpanel a small {
	text-align: center;
	width: 70px;
	background: url(pop_arrow.gif) no-repeat center bottom;
	padding: 5px 5px 11px;
	display: none; /*--Hide by default--*/
	color: #fff;
	font-size: 1em;
	text-indent: 0;
}
#footpanel a:hover small{
	display: block; /*--Show on hover--*/
	position: absolute;
	top: -35px;
/*--Position tooltip 35px above the list item--*/
	left: 50%;
	margin-left: -40px; /*--Center the tooltip--*/
	z-index: 9999;
}

Using elements, ID's and classes

The #id selector

A very common selector type is the ID based, which we saw in the "Hello, world" example. It uses the ID attribute of a HTML tag to locate the desired element. An ID should be unique, so you should only use this selector when you wish to locate a single, unique element. To locate an element with a specific ID, write a hash character, followed by the ID of the element you wish to locate, like this:

$("#divTest")

An example of it in use:

<div id="divTest"></div>
<script type="text/javascript">
$(function()
{
        $("#divTest").text("Test");
});
</script>

Now, while there is only a single element that matches our query above, you should be aware that the result is a list, meaning that it can contain more than one element, if the query matches more than one. A common example of this is to match all elements which uses one or several CSS classes.

The .class selector

Elements with a specific class can be matched by writing a . character followed by the name of the class. Here is an example:

<ul>
        <li class="bold">Test 1</li>
        <li>Test 2</li>
        <li class="bold">Test 3</li>
</ul>
<script type="text/javascript">
$(function()
{
        $(".bold").css("font-weight", "bold");
});
</script>

The element selector

You can also match elements based on their tag names. For instance, you can match all links on a page like this:

$("a")

Or all div tags like this:

$("div")

If you use a multi-element selector, like the class selector we used in the previous example, and we know that we're looking for elements of a specific type, it's good practice to specify the element type before the selector. Not only is it more precise, it's also faster for jQuery to process, resulting in more responsive sites. Here is a re-written version of the previous example, where we use this method:

$("span.bold").css("font-weight", "bold");

This will match all span elements with "bold" as the class. Of course, it can be used with ID's and pretty much all of the other selectors as well.

Selectors can do much more for you though. Read on for more cool examples.

Using attributes

In the previous chapter, we saw how we could find elements in a page from their class or their ID. These two properties are related because of the fact that you can use them to style the elements with CSS, but with jQuery, you can actually find elements based on any kind of attribute. It comes with a bunch of attribute selector types and in this article, we will look into some of them.

Find elements with a specific attribute

The most basic task when selecting elements based on attributes is to find all the elements which has a specific attribute. Be aware that the next example doesn't require the attribute to have a specific value, in fact, it doesn't even require it to have a value. The syntax for this selector is a set of square brackets with the name of the desired attribute inside it, for instance [name] or [href]. Here is an example:

<span title="Title 1">Test 1</span><br />
<span>Test 2</span><br />
<span title="Title 3">Test 3</span><br />

<script type="text/javascript">
$(function()
{
        $("[title]").css("text-decoration", "underline");
});
</script>

We use the attribute selector to find all elements on the page which has a title attribute and then underline it. As mentioned, this will match elements with a title element no matter what their value is, but sometimes you will want to find elements with a specific attribute which has a specific value.

Find elements with a specific value for a specific attribute

Here's an example where we find elements with a specific value:

<a href="http://www.google.com" target="_blank">Link 1</a><br />
<a href="http://www.google.com" target="_self">Link 2</a><br />
<a href="http://www.google.com" target="_blank">Link 3</a><br />

<script type="text/javascript">
$(function()
{
        $("a[target='_blank']").append(" [new window]");
});
</script>

The selector simply tells jQuery to find all links (the a elements) which has a target attribute that equals the string value "_blank" and then append the text "[new window]" to them. But what if you're looking for all elements which don't have the value? Inverting the selector is very easy:

$("a[target!='_blank']").append(" [same window]");

The difference is the != instead of =, a common way of negating an operator within many programming languages.

And there's even more possibilities:

Find elements with a value which starts with a specific string using the ^= operator:

$("input[name^='txt']").css("color", "blue");

Find elements with a value which ends with a specific string using the $= operator:

$("input[name$='letter']").css("color", "red");

Find elements with a value which contains a specific word:

$("input[name*='txt']").css("color", "blue");

Introduction
Everyone loves the gmail and facebook inline chat modules. This jQuery chat module enables you to seamlessly integrate Gmail/Facebook style chat into your existing website.



Features
1. Gmail style bottom right display of chat boxes
2. Keeps chat boxes open and stores state (data) even when pages are browsed/refreshed similar to Facebook
3. Displays “Sent at…” after 3 minutes of inactivity
4. Displays “X says…” & blinks chat boxes when window is not in focus
5. Minimize and close chat boxes
6. Auto-resize of text input box
7. Auto-scrolling of chat text
8. Auto-back-off polling policy (hits the server less-often when chat activity is low)
9. Extremely simple to integrate into existing site

Getting Started
First download the module (link below)

You must first create a mySQL table as below (or import db.txt provided in project files)

CREATE TABLE IF NOT EXISTS `chat` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `from` varchar(255) NOT NULL DEFAULT '',
  `to` varchar(255) NOT NULL DEFAULT '',
  `message` text NOT NULL,
  `sent` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  `recd` int(10) unsigned NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=539 ;


CREATE TABLE IF NOT EXISTS `users` (
  `uid` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(30) DEFAULT NULL,
  `password` varchar(30) DEFAULT NULL,
  `email` varchar(100) DEFAULT NULL,
  `gender` varchar(8) NOT NULL,
  `dob` varchar(16) NOT NULL,
  `phone` varchar(20) NOT NULL,
  `profile_image` varchar(50) NOT NULL,
  PRIMARY KEY (`uid`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=21 ;

--
-- Dumping data for table `users`
--

INSERT INTO `users` (`uid`, `username`, `password`, `email`, `gender`, `dob`, `phone`, `profile_image`) VALUES
(1, 'Swadesh', 'pass1', 'itswadesh@gmail.com', '', '', '', ''),
(2, 'Brijesh', 'pass1', 'brijesh@gmail.com', '', '', '', ''),
(3, 'Vimla', '', 'pass1', 'vimla@gmail.com', '', '', '');

Add the following scripts to your page template

<code><script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/chat.js"></script>
</code>

Add the following CSS to your page

<link type="text/css" rel="stylesheet" media="all" href="css/chat.css" />
<link type="text/css" rel="stylesheet" media="all" href="css/screen.css" /><!--[if lte IE 7]>
<link type="text/css" rel="stylesheet" media="all" href="css/screen_ie.css" />
<![endif]-->

Now in your list of users online, add “javascript:chatWith(’USERNAME’);” function where USERNAME is the username for that particular user who he/she wants to chat with.

Once that is done, edit chat.php and set your database parameters and try your website.

For better understanding, load 3 different browsers (internet explorer, firefox, safari) and point them to samplea.php, sampleb.php and samplec.php.

Click on “chat with john doe” link and watch the chat functionality come alive!

Inorder to integrate your existing website, you must place all your content between the “main_container” div tag.
