In this article, we look at how important JavaScript optimizations are analyzed. These general purpose techniques are designed for JavaScript on all browsers. Detailed graphs of all the performance results are given after each optimization. You will be amazed at the incredible speed improvements!

On the server side, you can improve performance by: Optimizing parallel downloads, caching frequently used objects, using HTTP compression, deploying delta encoding and rewriting URIs with mod_rewrite. By Andrew B. King. 0825 Read the original post: Advanced Web Performance Optimization

This tutorial takes a look at some of the basics of JavaScript, such as primitive data types, arrays, common operators and flow control statements. This final installment looks at arrays, conditions and loops. By Stoyan Stefanov. 0818 Excerpted from:Primitive Data Types, Arrays, Loops, and Conditions: Part 3

Any value that doesn’t belong to one of the five primitive types listed above is an object. By Stoyan Stefanov. 0811 Here is the original post: Primitive Data Types, Arrays, [...]

Before diving into the object-oriented features of JavaScript, one needs to look at some of the basics, including: primitive data types, such as strings and numbers, arrays, common operators, flow control statements, etc. By Stoyan Stefanov. 0804 The rest is here: Primitive Data Types, Arrays, Loops, and Conditions

This week you’ll learn what’s necessary to create an OpenGL ES 2.0 program that draws a single triangle. You’ll also learn how to create an on-screen render surface with EGL, load vertex and fragment shaders, create a program object and more. By Aaftab Munshi, Dan Ginsburg, Dave Shreiner. 0728 Read the original: Hello Triangle: An [...]

In the last article, we examined two visual features that could be used to enhance the appearance of the Autocomplete control. This week we’ll be delving into the last major functional piece of our Autocomplete Control: key event handlers.

In this article you’ll learn how to obtain and use the data from the query string portion of the URL by using a JavaScript query string parser. This script is especially useful for people whose Web sites are served by free hosting providers. By Joseph K. Myers. 0612 How to Use a JavaScript Query String [...]

In this series we’ve built a fully functional Autocomplete control within Eclipse. For the remaining installments, we’ll be updating the Autocomplete control’s layout to CSS, decoupling it from the Autocomplete.jsp page, tweaking the appearance of the list, and implementing additional functionality. By Rob Gravelle. 0522 See the original post here: How to Create an Ajax [...]

In part 5 of the series, the AutocompleteList JavaScript file, we wrote the client-side script to manage the behavior of the Autocomplete control in the browser. This week we’re going to finish the remaining Web files, including the AutocompleteSearch.jsp page. 0515 Go here to see the original: How to Create an Ajax Autocomplete Text Field: [...]

This week we’ll construct the The Fund Java class, which will act as a container for all the fund’s properties. On the server, we’ll store a collection of funds to be searched. Matching ones will be converted to a JSON array and returned to the browser for displaying in our Autocomplete list. By Rob Gravelle. [...]

This week we’ll be developing the AutocompleteServlet. The servlet acts much like an ASP, Perl or PHP script in that it’s executed by the server and accepts parameters from the browser. By Rob Gravelle. 0409 Source:How to Create an Ajax Autocomplete Text Field: Part 3

In part 3 of the series, we added the brains behind our Autocomplete text field’s search functionality. Now it’s time to turn our attention to the Web components. This week we’ll create the CSS file, since it, along with the JavaScript file, need to be linked to the AutocompleteSearch.jsp page. By Rob Gravelle. 0416 Read [...]
