It explains that jQuery improves performance, browser compatibility, and allows developers to implement critical UI functionality with less code. The document also outlines how to load and execute jQuery code, and provides examples of using jQuery for sliding effects, fading, and animation.

JQUERY TUTORIALS
- 3. What is JQuery? jQuery is not a language, but it is a well written JavaScript code. As quoted on official jQuery website, "it is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development”. In order to work with JQuery, you should be aware of the basics of JavaScript, HTML and CSS.
- 4. Why Jquery? It helps to improve the performance of the application It helps to develop most browser compatible web page It helps to implement UI related critical functionality without writing hundreds of lines of codes It is fast It is extensible – jQuery can be extended to implement customized behavior Other advantages of jQuery are: No need to learn fresh new syntaxes to use jQuery, knowing simple JavaScript syntax is enough Simple and cleaner code, no need to write several lines of codes to achieve complex functionality JQuery is very compact and well written JavaScript code that increases the productivity of the developer by enabling them to achieve critical UI functionality by writing very small amount of code.
- 5. How to use JQuery? jQuery usually comes as a single JavaScript file containing everything comes out of the box with jQuery. It can be included within a web page using the following mark-up: How to load JQuery?
- 6. How to execute JQuery code? There are two ways you may want to execute jQuery codes.
- 7. 1st The benefit of executing jQuery code in this way is that it doesn’t wait for the whole page to load completely, so in case you want the user to see the effects as soon as the corresponding elements are loaded, you can use this. However, the disadvantage is that if the element on which jQuery has to execute has not loaded, then it will error out or you will not get the desired result; so while using this way of executing jQuery code, you will have to make sure that the element on which you want to work with jQuery is loaded first (you can place your jQuery code right after your HTML element).
- 8. 2nd This is the better and safer way to execute jQuery. This makes sure that jQuery code will execute only if complete page has been loaded in the browser so you are rest assured that user will not see any undesired behavior on the page.
- 9. Ease of use Large library Strong opensource community Great documentation and tutorials Ajax support Functionality maybe JQuery javascript file required
- 10. JQuery provides a simple way to select single element or group of elements. You can access element by type (div, span, p), id, CSS class and attribute, etc. SELECTORS
- 11. SLIDING EFFECT
- 12. Example…JQuery provides three methods to show or hide elements in sliding behavior. SlideDown(speed, callback): This method gradually increases the height of the elements, from hidden to visible. SlideUp(speed, callback): This method gradually decreases the height of the elements, from visible to hidden. SlideToggle(speed, callback): This method toggles between SildeUp() and SlideDown() for selected elements.
- 13. I created Box using DIVs and choose DIV having id “contentArea” for sliding. Register click event of the HTML element and call SlideToggle and SlidUp method for the “contentArea”. More details of this example are available in the attached project.
- 14. Fade Effect
- 15. Example…JQuery also provides four methods to gradually change the opacity of the selected element using Fade effect. fadeTo(speed, opacity, callback): This method changes the opacity of selected elements to specified opacity. fadeIn(speed, callback): This method gradually increases the opacity of the elements, from hidden to visible. fadeOut(speed, callback): This method gradually decreases the opacity of the elements, from visible to hidden. fadeToggle(speed, callback): This method toggles between FadeIn() and FadeOut() for selected elements.
- 16. I will set the opacity of the image on hover. Add images in to the DIV and assign id “fadeExp1” to div. In ready() function, set the default opacity of all images using $(“#fadeExp1 img”).fadeTo(0, 0.3); statement. Then register Hover event on each image and provide two functions in it, one for mouse over and one for mouse out and set the opacity of element there.
- 17. Animation Effect
- 18. Example… JQuery also provides an easy way to animate element. the syntax of animate method is .animate( properties, [duration], [easing], [complete]). properties: A map of CSS properties, which changes during animation duration: String or number to determine the duration of the animation easing: The name of easing function to use for the transition complete: A function to call on the complete of animation
- 19. A very cool and simple example for the icons list in your website, simply register hover event on the image. On mover over, set top=-15 and on mouse out set top=0 again. Don’t forget to set the relative position of the image.

Editor's Notes
- Your introductory or title slide should convey the overall “feeling” and focus of your presentation. For instance, I typically present about small-business trends, new business ideas, growth opportunities or other positive trends. In this sample presentation, I’m talking about new business ideas, so I used a sun graphic in this slide template to convey a positive feeling. Personalize this slide template with your company’s logo. To add a logo to all slides, place it on the Slide Master. To access the Slide Master, on the Themes tab of the Ribbon, click Edit Master and then click Slide Master.Disclaimer: You understand that Microsoft does not endorse or control the content provided in the following presentation.

- I like to speak spontaneously, so I use PowerPoint as an outline to keep me on track. It’s best to keep your PowerPoint text brief, simply reinforcing key points you will talk about at more length. You can use this slide template to convey a series of steps or related points in a short format.
- A plain old bulleted list can get boring, so use graphics to liven it up. An image that conveys what you’re saying in visual format (like this diagram) can reinforce your ideas in the audience’s mind.
- I like to use an off-balance layout to keep things from getting too symmetrical. Customize this slide template graphics of your choice, including photos, clip art, your logo or illustrations. Good photos really help cement an idea in the audience’s mind. This slide is animated to display an appropriate image as you introduce each business type.
- I often use color and graphics to add excitement to a presentation. Just because it’s about business doesn’t mean it has to be staid—you need movement, energy and color, as in this slide template. Use this slide template to illustrate relationships or processes. In this slide, I used it to show how demographic trends create a new consumer group and what products that group purchases. You could also use it to illustrate your sales cycle or relationships among departments in your company.
- Insert a chart in this slide template to illustrate your topic visually, then use bullets or color to call out key findings or points from your chart in a brief format.
- This slide template can show steps, stages or how various elements or factors combine to make one key result or goal. For instance, you could show how various departments in your business work together to make the sale, how key customer groups will all purchase your product, or how different funding sources will provide the total you need. This slide template also makes an excellent concluding slide for your presentation, enabling you to graphically sum up your key points into one final whole.
