Anyone who has used AJAX technology knows the famous JQuery. Although I have watched AJAX videos before, I was still vague about WEB applications at that time, but I don't know how HTML, JSP, and Servlet work, I don't even know what JQuery is packaging. Today's learning combined with yesterday's JavaScriptDOM content makes me very clear about this. JQuery princip

The Code is as follows: // Bad$Second.html (value );$ Second. on ('click', function (){Alert ('Hello everbody ');});$ Second. fadeIn ('slow ');$ Second. animate ({height: '120px '}, 500 ); The Code is as follows: // Suggestions$Second.html (value );$ Second. on ('click', function (){Alert ('Hello everbody ');}).

It is not uncommon to discuss jQuery and javascript performance. However, I plan to summarize some speed tips and some of my own suggestions in this article to improve your jQuery and javascript code. Good code will increase the speed. Quick rendering and response means a better user experience. First, remember that jQuery is javascript in your mind. This means w

, jQuery's default animation queue ). It allows you to pause between two animation actions, instead of involving callback functions and setTimeout .. The first parameter of delay () is the number of milliseconds you need to set: Js Code JQuery ('# foo ') . SlideDown () // Slide down . Delay (200) // Do nothing for 200 MS . FadeIn (); // Fade in JQuery ('# foo '

('border', '1px solid red ');}) Simplified javascriptIn general, it is best to merge functions as much as possible. // Bad$ First. click (function (){Define first.css ('border', '1px solid red ');Define first.css ('color', 'blue ');});// Suggestions$ First. on ('click', function (){$First.css ({'Border': '1px solid red ','Color': 'blue'});}); The Code is as follows: // Bad$ First. click (function (){Define first.css ('border', '1px solid red ');Define first.css ('color', 'blue ');});// Sugges

This article describes examples of jquery's Common special effects. For more information, see section 1. Use jQuery fadeIn () to fade in hidden elements.

external margins, and transparency of the element are gradually changed from hidden to completely visible. Callback (optional) indicates the function to be executed after the show function is executed. 2. Hide control elements In jQuery, the show method corresponds to the hide method. The Hide method is used for hiding (you can control the hiding speed of elements) Syntax: $ (Selector). hide ([speed], [callback]); Its parameters are the same as thos

Today's study combined with yesterday's javascriptdom content, let me be very clear about this. The jquery principle: "Write less, do more.", this sentence has fully explained its ability to simplify the use of JAVASCRIPTDOM programming!

Old Tong is a very experienced software teacher, before he in Dalian software compa

, the Class selector is the slowest selector; in IE, It loops through the entire DOM. Avoid using it if possible. Do not add Tags before the ID. For example, it loops through all the var content = $('div#content'); In the same way, transmitting data from multiple IDS is redundant. var traffic_light = $('#content #traffic_light'); 3. cache jQuery objects Develop the habit of saving jQuery objects to a varia
