Quick Synopsis of Part 2

Let's move ahead now on jQuery effects.

Preparing the workspace

Add the following code in your new HTML to make it ready for the rest of the article.

<html>

<head>

    <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/smoothness/jquery-ui.min.css" rel="stylesheet" type="text/css" />

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"></script>

    <meta charset="utf-8" />

    <title>jQuery Demystified Part 3</title>

      <style>

        /* we will use this section for adding css classes */

    </style>

</head>

<body>

      <script>

        $(document).ready(function () {

            // We will use this for adding our jQuery

        });

    </script>

</body>

</html>

Working with jQuery Effects

Add Class

Add this peice of code in the html section:

<div class='addcls'></div>
Add these two classes in your style section:

.addcls{

width:50px;

height:20px;

background-color:orange;

}

.addclsOP{

width:300px;

height:80px;

background-color:blue;

}

Here 'addcls' is the default class and we will change it to 'addclsOP' .
Add this in your script section:

$(document).ready(function () {

    $(".addcls").click(function () {

        $(this).addClass("addclsOP", 1000, "easeOutBounce");

    });

});

Here we add the "addclsOP" in the div when the user clicks on it. This changes the property of the element on which the click is performed. ".addClass" has syntax like this: ".addClass("class_to_add",duration,other_options)".

Remove Class

Append this in your HTML section:

<div class="addclsOP addcls"></div>

This div has two classes "addclsOP" and "addcls". We'll remove the addclsOP on click of user on the second div.
Append this code to your script section:

$( ".addclsOP" ).click(function() {

$( this ).removeClass( "addclsOP", 3000, "easeOutBounce" );

Here the class addclsOP is removed from the div when the user clicks on that div. The general syntax of ".removeClass" is ".removeClass("class_to_remove",duration,other_options)".

Animate

Append this in your HTML section:

<div class='clrAnim'>Color Animation</div>

This div will be used to animate its color and size when the user clicks on it.
Append this class in your style section:

.clrAnim{

width:300px;

height:80px;

background-color:pink;

}

This is the default class on the div and its content will be changed using the ".animate" method.
Now append this script in your script section:

$(".clrAnim").click(function () {

    $(this).animate({

        color: "white",

        backgroundColor: "black",

        height: "160px"

    }, 1000);

});

The syntax for ".animate" is: ".animates("options_to_animate",duration,other_options)".

Effect

Append this HTML snippet in your HTML:

<div class='effectDemo'>effect Demo</div>

On this div we will be performing various effects.
Append this class in your Style section.

.effectDemo{

width:300px;

height:80px;

background-color:brown;

}
Append this code in your script section

$(".effectDemo").click(function () {

$(this).effect("explode", 2000, "easeOutBounce");

});

Here we are performing the "explode" effect on the div when the user clicks on it. We have various kinds of effects, like blind, fold, slide, pulsate and so on. The general syntax is .effect("Effect_name",duration,other_options).

Hide

Append this snippet in your HTML

<div class='hidecls'>Hide Demo</div>

We will hide this div when the user clicks on it.
Append this class in your Style section:

.hidecls{

width:300px;

height:80px;

background-color:yellow;

}
Append this code in your script section:

$(".hidecls").click(function () {

$(this).effect( 2000);

});

Here we are performing the "Hide" effect on the div when the user clicks on it. The general syntax is ".hide(["Effect_name"],[options],[duration],[callback])." Everything that is in [] is optional, so simply ".hide()" will also work.

Switch Class

Append this snippet in your HTML

<div class="switchDemo">Switch CLass Demo</div>

On this div we will perform various effects.
Append this class in your Style section:

.switchDemo{

width:300px;

height:80px;

background-color:olive;

}
Append this code to your script section:

$(".switchDemo").click(function () {

$(this).switchClass("switchDemo", "clrAnim", 3000, "easeOutBounce");

});

Here we are performing the "switchClass" effect on the div when the user clicks on it. The general syntax is ".switchClass("Current_class","New_class",[duration],[callback])". The callback event occurs when the switching is completed.

Toggle Class

Append this snippet to your HTML:

<div id="tc" class="td">Toggle demo</div>

On this div we will be performing the Toggle class effect between the "td" class and "td2" class.
Append this class in your Style section:

.td{

width:300px;

height:80px;

background-color:green;

}

.td2{

width:300px;

height:160px;

background-color:black;

}

These two classes will be switched on click of the user.

Append this code in your script section

$( "#tc" ).click(function() {

$( this).toggleClass( "td2",1000);

});

Here we are performing the "toggleClass" effect on the div when the user clicks on it. The general syntax is ".toggleClass("Class_to_switch_with",[duration],[easing_type],[callback])." The class will be added on the div if it's not present and if it's present then it will be removed.

Toggle

Append this snippet to your HTML:

<div id="container">

<div id="slider">Toggle demo</div>

</div>

On this div we will be adding a sliding effect using toggle.
Append this class in your Style section.

#slider{

    width: 180px;

    height: 100px;

    background: #ccc;

}

#container{

height:100px;

}

These two classes are the design of our slider.

Append this code in your script section

$("#container").click(function () {

$("#slider").toggle("slide", { direction: "left" }, 1000);

});

Here we are performing the "toggle" effect on the div when the user clicks on it. It looks like a slider. The general syntax is ".toggle("effect_name",[options],[duration],[callback])".
