We also went over the recipes that perform the task of filtering arrays. In the next chapter, we will see several recipes that deal with event handling. We will also learn how to highlight the text dynamically, and how to make an image bright and blur with mouse movements. We will also see the process of creating image-based rollovers, event based addition and removal of text, and more.

Events may be in terms of hover, click, double-click, and so on. We will see events related to both mouse and keyboard. Though 6 covers visual effects and describes how to do animations with images, there are a few animation effects related to text included in this chapter because they are useful when reacting to events. The recipes that we are going to see in this chapter are as follows: Finding out which button is clicked Triggering events automatically Disabling a button after it is clicked once Handling mouse events Finding out which mouse button is pressed Finding the screen coordinates of a mouse-button press Highlighting text dynamically Making an image bright and blurred with mouse movements Finding when an element gains and loses focus Applying hover effects on buttons Toggling the application of a CSS class Creating image-based rollovers Adding and removing text in response to events Applying styles in response to events Displaying word balloons Creating Return to Top links Offering Read More... links Displaying text with an animation effect EAN / UCC - 14 Generator In C# Using Barcode generation for VS .NET Control to generate, create USS-128 image in VS .NET applications. www.OnBarcode.comPDF-417 2d Barcode Drawer In Java Using Barcode encoder for Java Control to generate, create PDF 417 image in Java applications. www.OnBarcode.comCHAPTER 3 EVENT HANDLING

On every web page, you find several buttons, each meant for doing different jobs. In order to take the correct action, you need to know which button has been clicked. Solution
In this recipe, we assume there are two buttons and we want to know which of them is clicked by the user. Let us define an HTML file that contains the text Bold and Italic to which we will assign the shape of a button by applying different style properties. The HTML file will appear as shown here: <body> <span class="bold buttons">Bold</span> <span class="italic buttons">Italic</span> </body> In the external style sheet style.css, we write the CSS class by name buttons to give the shape of the button to the text. The CSS class buttons may have the following properties: .buttons{ width: 100px; float: left; text-align: center; margin: 5px; border: 2px solid; font-weight: bold; } Let s write the jQuery code to attach the click event on the buttons, using the bind() method: $(document).ready(function() { $('.bold').bind('click', function(){ alert('You have clicked the Bold button'); }); CHAPTER 3 EVENT HANDLING
$('.italic').bind('click', function(){ alert('You have clicked the Italic button'); }); }); Applying Click Events to Both the Buttons
Instead of adding a click event to each button individually, we can apply the click event to both buttons simultaneously by adding the click event to the whole button class. For this, we use the following jQuery code: $(document).ready(function() { $('.buttons').bind('click', function(){ alert('You have clicked the ' +$(this).text()+' button'); }); }); Attaching the Event Directly
We can also attach the event to any specified element directly without using the bind() method. Let s see the jQuery code that attaches the click event to the element of the class buttons: $(document).ready(function() { $('.buttons').click(function(){ alert('You have clicked the ' +$(this).text()+' button'); }); }); Using the Target Attribute of the Event Object
The event object is automatically sent to the event-handling function by JavaScript and contains details of the event. One of its attributes, called target, can be used to find out the element where the event has occurred. The jQuery code using the target attribute of the event object to find out the element where the click event has occurred is as shown here: $(document).ready(function() { $('.buttons').click(function(event){ var $target=$(event.target); if($target.is('.bold')){ alert('You have clicked the Bold button'); } if($target.is('.italic')){ alert('You have clicked the Italic button'); } }); });
