Learning from Twitter An issue popped up on Twitter this past week that caused the web site to be generally unusable for many users. It appears as if attempts to scroll were unbearably slow and caused the site to be unresponsive. The Twitter team investigated and determined that if they reverted the version of jQuery that they used back to 1.4.2 from 1.4.4 the site would be responsive again. After more investigation they determined that the code that was slow was doing a contextual selector search for an item by class name, for example: $something.find(".class"). So – what happened? However, as with every performance change, while some things get way faster some things can also get slower. What’s interesting here is that we’ve been using querySelectorAll for our default selector engine in jQuery for quite some time now (doing $(‘.class’) would use querySelectorAll). This brings up the important point: Just how much faster is getElementsByClassName compared to querySelectorAll? So. Comments are closed.
Parallax Scrolling and Its Usage in Web Design The parallax effect, also called parallax scrolling, is a special technique used in computer graphics at first, where background images move by the camera slower than foreground images. This is the actual concept where websites with parallax scrolling started. It was widely used in the gaming industry more than 10-15 years ago and it is still used today in different domains. In the past years the parallax effect started to be used widely in web design. Its popularity went through the clouds when Nike redesigned their website based on this concept. The design concept started to be used because it is actually quite cool. Parallax Scrolling Examples Although this is usually the case, utilizing the parallax scrolling effect doesn’t have to limit you to a fake 3D effect. When they see it for the first time, people use to think that the effect is nice. Performance Issues Although the effect looks brilliant, there are some downsides to it, such as the performance issues. New age technologies

Masked Input Plugin First, include the jQuery and masked input javascript files. Next, call the mask function for those items you wish to have masked. jQuery(function($){ $("#date").mask("99/99/9999"); $("#phone").mask("(999) 999-9999"); $("#tin").mask("99-9999999"); $("#ssn").mask("999-99-9999");}); Optionally, if you are not satisfied with the underscore ('_') character as a placeholder, you may pass an optional argument to the maskedinput method. Optionally, if you would like to execute a function once the mask has been completed, you can specify that function as an optional argument to the maskedinput method. You can now supply your own mask definitions. jQuery(function($){ $.mask.definitions['~']='[+-]'; $("#eyescript").mask("~9.99 ~9.99 999");}); You can have part of your mask be optional. jQuery(function($){ $("#phone").mask("(999) 999-9999? If your requirements aren't met by the predefined placeholders, you can always add your own. jQuery(function($){ $("#phone").mask("#hhhhhh");});

Formalize CSS - Teach your forms some manners! Redrawing Elycharts in a one document jQuery Mobile environment Signature Pad · Thomas J Bradley Download ZIP—GitHub Introduction The Signature Pad jQuery plugin will transform an HTML form into a signature pad. The Signature Pad has two modes: TypeIt and DrawIt. In TypeIt mode the user’s signature is automatically generated as HTML text, styled with @font-face, from the input field where they type their name. The drawn signature is written out to a hidden input field as a JSON array using JSON.stringify(). Obviously, Signature Pad has a couple extra dependencies: Douglas Crockford’s json2.js and FlashCanvas 1.5. Signature Pad tries to maintain a certain level of progressive enhancement, while still giving developers enough control. Signature Pad works with both mouse and touch devices. Get the source code on GitHub: Demos Demo of accepting a signature—this demo showcases an HTML form and the Signature Pad ready to accept a new signature. How to Use the Plugin Don’t forget to include the flashcanvas.swf file. Accepting Signatures Javascript
