Yahoo search gallery provides you many existing search enhancements that you can add after logging to yahoo. [Via labnol.org].Try various enhancement like LinkedIn Profile, IMDB results, StumbleUpon Reviews and other popular ones.

And you can also create your own search enhancement using step by step method using Presentation application (SearchMonkey Guide).

SearchMonkey API unables you to modify how particular links appears in search results. You can add images, related links and other html formatting but it does not unable you change position of a page in search result. I was unable to find feature which will enable us to filter sites which requires you to login or sites like ebay and amazon which may not be relevant to us by making their appearance farther in search results.

But still these enhancements provides you little summary of search results which is very useful like in case of movie reviews, people profile via linkedIn, stock information etc thus sometimes making opening the actual webpage unnecessary.

You can add this one line to .htaccess file (create this file if it doesn’t exist)

ErrorDocument 404 /web404.html

This will redirect all queries for files not found in that directory and sub directories to web404.html
On that page you can provide user with:

• Link to homepage
• Tell them to check the URL or Go Back
• Search functionality for your website will be very useful.

So yesterday I added a 404 page for my website: Check it out

I have also added similar functionality for my wordpress blog. For setting up 404 Error page on wordpress follow this well compiled article: Creating an Error 404 Page

• Adobe AIR Runtime : Necessary for running AIR applications. (For windows & mac)
• AIR_SDK Provide necessary libraries to build AIR application

Having Adobe AIR extension for Dreamweaver CS3 can be very helpful as it facilitates to package and preview .air application files directly within Adobe Dreamweaver CS3.

As my first AIR application, I ported my rubiks cube timer as a desktop application (RubikTimer.air). Its very easy using dreamweaver extension, have a look here : Create your first HTML-based AIR application with the AIR SDK (great tutorial for beginners).

One problem I faced: Usually setInterval(“display()”,500) works with Firefox/IE but it was not starting with no error message to look into but then i found out about using Adobe CommandLine tool. (via Three ways to debug Adobe javascript Application). It´s called ADL and resides in the /bin folder of the SDK. ADL showed the Error: “Unsafe javascript”. Then after some random changes when i change it to “setInterval(display,500)”, It started working. Another problem I faced was related to keypress events in javascript, were not working with AIR (still have to resolve this issue)

Download RubikTimer.air here

• Play with html using javascript

Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

Firebug is firefox addon that helps you in webdevelopment with
its powerful feature such as javascript debugger, Inspect and edit HTML, Tweak CSS to perfection, Monitor network activity, Explore the DOM and many more. Feature I like most is its quickly diagnosing problem, it allows you set break points and checking intermediate values of variable for javascript thus making a great javascript debugger. Many times you are stuck at where did the code went wrong so in way its a lot useful in saving time.

I also like is its inspecting html and modifying html and css on fly and see the results with helpful tooltips. It also help in positioning of divs, images with its nice feature of visuallizing css metrics with ruler and box model coloring(HTML inspecting).

It other great feature is its interface which is comes with browser window split in two halves one for your website and one is extension interface (though it also can be detached from it). I am also a fan of Web developer toolbar extension but what it lacks is a java debugger and this great interface but both are a must of a web developer.

<script type="text/javascript">function test(){alert("test javascript");}</script>

Action on events:

Example of events can be mouseclick, keystroke, submitting form etc.
With onload()

 <body onload="init()">

Now init() function will be called when this html page is being loaded.
For links, javascript function can be evoked when clicking, mouseover over links like

 <a href="javascript:replay()" mce_href="javascript:replay()">Refresh ! </a>

Now function replay() will be called when Refresh! is clicked. For input text box

<input type="text" size="30" id="search" onchange="suggest()">; 

Now whenever content of textbox changes the function suggest() will be called. It can be useful when feature like google suggest has to be implemented or so.

On submitting forms:

<form method="post" action="some.php" onsubmit="return checkForm()">

So whenever this form is being submitted checkForm() function will be called and can be helpful in verifying values of form elements.

onMouseOver and onMouseOut:

<a href="http://www.aburad.com/blog" mce_href="http://www.aburad.com/blog" onmouseover="fade()"><img src="image.gif" mce_src="image.gif"> </a>

Now when mouse is over image fade() function will be called and can be used for animate and styling purposes.

Registering of events

A simple way can be:
Conside the html code : <div id="sample"> ..... some... html..text.. </div>
Now using javascript you can register event for this div by:

 var div_sample = document.getElementById('sample');div_sample.onmousedown=sampleMouseDown ; 

Now whenever mouseover ocours over this div html element sampleMouseDown() function will be called. Events can also be registered using addEventListener() . Find more information baout it here:Advanced event registration models

Modify Style and values for html elements

Within some javascript function, you can first get the element object by getElementByID() getElementsByName() for example conside the javascript code:

document.getElementById("colorcode").innerHTML = "#000000";
document.getElementById("bgtest").style.backgroundColor= "green";


The first line find the html element with id colorcode and then set its value to “#000000″ using innerHTML. In second line, it sets the background of html element with id “bgtest” to green.

Some other tweaks which were useful :

• Calling some function repeatedly with some time interval, consider javascript code:

var intervalID = setInterval(drawCurve, 100);


So the drawCurve() function will be called repeatedly after 100ms. You can cancel this process( removing repeatedly calling) by clearInterval(intervalID);

• You can use setTimeout(drawCurve,100) function to delay drawCurve() execution for a specified time period(100ms).

• Calling a php function inside javascript:

var testImg = new Image();
testImg.src="form.php?name=form_value" mce_src="form.php?name=form_value";


Now here in form.php you can fetch value of variable name using $_GET and can perform appropriate action.
