  JavaScript efficiency catch up


JavaScript is a very flexible language, we can write JavaScript code freely with various styles, different kinds of codes will have different execution efficiency. Here we summarize some tips we get from our development. Efficiency of JavaScript itself JavaScript has execution context chain, closures, prototype inheritance, eval etc. It brings us some magic features, but it also introduces the performance issue, if we don't use them properly, it will affect the codes execution efficiency. 1. Glo...

  PHP to get long running process progress dynamically


Frequently in web applications, we may have a request to the back end system which may trigger a long running process such as searching huge amount of data or a long running database process. Then the front end webpage may hang and wait for the process to be finished. During this process, if we can provide the user some information about the progress of the back end process, it may improve user experience. Unfortunately, in web applications, this seems not an easy task because web scripting lang...

  Show Bootstrap tooltip in AngularJS ng-repeat elements


In contemporary web application development, many front-end frameworks have been used to accelerate the speed of development and circumvent browser compatibility issues. Among them, AngularJS and Bootstrap are two frequently used.  AngularJS is a MVC JavaScript framework developed by Google to provide easy synchronization between user view and data model. While Bootstrap is developed by Twitter and it eases the work of designing a simple and concise UI without much manual design work ...

  Turn browser into notepad with one line of code


This is the code shared by Jose on codewall. When you type data:text/html,   into the address bar of the browser and press enter, the browser will turn into a notepad which you can edit. Why it works? This uses Data URI’s format and it tells the browser to render HTML. But contenteditable is a property of HTML5, so this can only work in the web browser which supports this property. Here are some interesting contents. Some people make some changes to the code encouraged by the ide...

  What's on your Learning List?


How do you track and decide what topics you want to spend time learning? For a while, I didn’t have a real good solution. Something would trigger me to remember “Oh yeah! I really wanted to learn more about that”. I would spend the evening doing busy learning - it seemed like I was learning but I really wasn’t. Instead of trying to do Deliberate Practice, I’d fool myself into thinking I was investing my time wisely by reading blog posts and examples but not actually doing much o...

  What we still can’t do client-side


With the rise of all these APIs and the browser race to implement them, you’d think that currently we can do pretty much everything in JavaScript and even if we currently can’t due to browser support issues, we will once the specs are implemented. Unfortunately, that’s not true. There are still things we can’t do, and there’s no specification to address them at the time of this writing and no way to do them with the APIs we already have (or if there is a way, it’s unreasonably ...

  Native Client Brings Sandboxed Native Code to Chrome Web Store Apps


Wouldn’t it be great if you could create web apps using your existing C and C++ code? Native Client lets you do just that, and it is now enabled for Chrome Web Store apps in Google Chrome’s beta channel. Native Client apps live on the web platform, so you don’t need to create separate versions of your app for each operating system. Rather than relying on OS-specific APIs, Native Client apps use Pepper, a set of interfaces that provide C and C++ bindings to the capabilities of HTML5. This m...

  Best practices of front end optimization


1. Use DocumentFragment or innerHTML to replace complex elements insertion DOM operation on browser is expensive. Although browser performance is improved much, multiple DOM elements insertion is still expensive and will affect the page load speed. Assume we have an ul element on our page, we now want to retrieve a JSON list using AJAX and then update the ul using JavaScript. Usually we may write it as : var list = document.querySelector('ul'); ajaxResult.items.forEach(function(item) { // ...

  About browser event


First look at following codes: var $ = KISSY.all; $(‘a’).on(‘click’,function(e){ doSomeThing();//This function seems very famous e.halt(); }); The above codes seem complete the work we want them. The browser will not redirect us to the link in href, but is there some issue with the codes above? Before explaining what's wrong with the above codes, we first need to understand some concepts. Browser default behavior When we click a link, the browser will redirect us to anoth...
