I’m trying to make my site faster, but I noticed that Facebook widgets slows down download, should i remove them? I think that it’s usefull for users see how many people likes a page, don’t you?
Firebug is a firefox extension that allows you to easily find and fix javascript issues with ajax applications.
Yes, split Mozilla Firefox or Google Chrome down the middle in one tab. For the multi-tasking type this will enable you to create 2 side by side “panels” in Firefox/Chrome in the same tab so you can browse two sites at once side by side.
Why not switch between tabs?
A few reasons, maybe you want to compare search results on both Google and Yahoo or do side by side comparisons of products or checking templates/themes look. Maybe you want to reference something in the left panel and type about it in the right and switching tabs is a pain.. Well this will enable you to do just that. See examples:
A comparison search for Chrome on Google and Yahoo
Click for larger view
Reference content in one panel, write about it in the other
Click for larger view
To use simply drag and drop the following in your bookmarks…
When clicked, a pop-up box asks for the first URL which will be the left panel and the URL you are currently on will be entered by default however this can be changed so in my dual search i entered Google.com for this one. Once you ok it, it will ask for the second URL which is the right panel and i entered Yahoo.com for my search comparison.
Simple, Google Chrome or Mozilla Firefox split down the middle with a double panel all in one tab.
Some time ago I wrote this post where I explained some useful tips to enrich HTML Form using simple JavaScript functions. Some readers asked to me to illustrate similar examples using MooTools and unobtrusive JavaScript code, so in this tutorial I implemented the Twitter-like chars counter example of my previous post. This counter decreases, from the max value of available chars in the input field (20 in this example) to zero, while you type something into the input field:

In this post I want to illustrate how to get the ID of DOM elements using MooTools and unobtrusive elegant code.
1. An “Obtrusive” way to implement it
Before to explain how to do it with MooTools, I think it’s better take a look at the following HTML code: Read the rest of this entry »
In this first lesson you can see how to manipulate element properties, in particular how to get DOM element by ID, how to use getStyle(), setStyle() (to get and set CSS properties), toInt() to convert string to number and some examples to introduce how to write unobtrusive JavaScript code with MooTools.
1. Add Mootols framework to your page
First, you have to download the latest version of MooTools and add a link to the framework within the <head> tag of the page: Read the rest of this entry »
Open config.php file (Under application/config folder) and change the following line
$config['base_url'] = “”;
to
$config['base_url'] = “http://localhost/cimenu”; //here cimenu is the folder where all the files of CodeIgniter is
Now open autoload.php file (Under application/config folder) and change the following line
$autoload['helper'] = array();
to
$autoload['helper'] = array(‘url’, ‘form’);
Now create a folder named menu under cimenu(This is the project name) folder, that is, in your root folder. Now put all the files of the external menu to the menu folder under cimenu.
Lets create a php file and name it mymenu.php under application/controller folder and write the following code: Read the rest of this entry »
Look at this example. When you hover over the box, the border, background color, and foreground colors change. This is caused by JavaScript dynamically changing the box’s CSS properties much like it does the “visibility:” property in pop up menus. This opens a whole new world of dynamic styling opportunities as most CSS properties can be accessed.
The generic form of the JavaScript reference to change a CSS property is:
document.getElementById("div_id").style.CSS_property_to_change = "new_CSS_value_in_quotes";
JavaScript does not always use the same term to refer to a property as CSS does. This is the biggest thing to keep in mind as you refer to CSS properties in JavaScript. Now lets start coding the example.
