New OpenSource project

I’ve just started my own OpenSource web framework. I name it “HashHandler”. Its main functionality is helping to handle the hash “#” in URL. This will make developer easier to build single page web application. This framework is still in very early stage. It can be used to build single page web application, however, it lacks of functionality & documentation. It might be full of bugs. I will spend time improve this framework & write documentation. Meanwhile, you can play around with it.

Here’s project source: https://github.com/borey/hash_handler

JavaScript is popularly used for adding extra functionality to web page. As the popularity developing dynamic web page and Rich Internet Application(RIA) grow, many developers have started to develop their RIA and dynamic web page using JavaScript library without knowing the pure JavaScript DOM & Event.

In this talk, I’m going to introduce the DOM & Event using pure JavaScript without any help from other library. At the end of the talk, I’m expecting to get all the participants get more understanding on usage of DOM & Event in JavaScript.

Cannot install Sun JDK on Ubuntu 10.04

Recently, I’ve upgraded to use Ubuntu 10.04. It seems that by default, I can’t just use “sudo apt-get install sun-java6-bin” to download the java package. After doing Google for the solution, I’ve come across a working solution. I need to add apt repository first, before I can download the java package:

sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”
sudo apt-get update

NOTE: Be mindful of the double-quotes in case you are doing a copy-paste from the webpage.

Here’s a littile progress bar I’ve created using JavaScript. I’ve use JavaScript setInterval() to increase the progress bar & clearInterval() to stop progress bar.

//Create dom
var bar = document.createElement("div");
progressBar = document.createElement("div");
with(bar.style){
    width = "200px";
    height = "10px";
    position = "absolute";
    border = "1px solid #949DAD";
};

with(progressBar.style){
    width = "0px";
    height = "100%";
    background = "#D4E4FF none repeat scroll 0 0";
};

bar.appendChild(progressBar);
document.body.appendChild(bar);

//start setInterval
var x = window.setInterval(
	function(){
                progressBar.style.width = parseInt(progressBar.style.width) + 5 + "px";
            //stop interval when progress bar width = 200
            if(parseInt(progressBar.style.width) == 200) clearInterval(x);
	},
	40
);

HTML – Tab Index

 Uncategorized  2 Responses »

The tabIndex property sets or returns the tab index for a text field. The tab order defines the order the elements appear if you navigate the page using the “tab” button on the keyboard.

Given the scenario that we have a webpage which has many links & a form for users to complete. In this case we see that the main focus is the form not the links before the form. If users were to use tabkey to browse to the form, it would take many keypress before users are able to go to form. We can solve our problem by specifying the tabindex property.

Here’s a simple example:

<pre><form>
    <label for="name">Your Name</label>
    <input value="" id= "name" name="name" type="text" tabindex = "1">

    <label for="email">Your E-mail</label>
    <input value="" name="email" id="email" type="text" tabindex = 2>

    <label for="mobile">Your mobile</label>
    <input value="" name="mobile" id="mobile" type="text" tabindex = -1 >

    <label for="message">Message</label>
    <textarea rows="4" cols="30" name="message" id="message" tabindex = 3></textarea>
</form>
</pre>

“tabindex = -1″ will make the tab not go though the field when the user clicks tabkey.
