small program (url) related to javascript



<html>

<head>

<script type="text/javascript">

window.location.href='http://www.google.com';

</script>

</head>

<body>

</body>

</html>



the above program is working but when I change the program using onclick event it didn't work.But the below code is perfectly valid when you just put alert box instead of window.location.href and you can check it by yourself.
<html>

<head>

<script type="text/javascript">

function hello()

{

window.location.href='http://www.google.com';

}

</script>

</head>

<body>

<form>

<input type="submit" id="intro" onclick="hello()" value="Reload the page" />

</form>

</body>

</html>

then one of my friend named whosaidwhat figured it out it is due to type submit and so he advised to change it to button and i tried it .Yes it worked.
<html>

<head>

<script type="text/javascript">

function hello()

{

alert("welcome");

window.location.href='http://www.google.com';

}



</script>

</head>

<body>

<form>

<input type="button" id="intro" onclick="hello()" value="Reload the page" />

</form>

</body>

</html>

when I asked the reason whosaidwhat bro told as follows
"I cannot really give you detailed information on the inner workings of how web browsers handle javascript on submit buttons. I imagine that because it is a submit button it will be submitting the forms data to another page, and would not be expecting a URL redirect as it would break the forms submission. The browser is probably set up to ignore the redirect if the type of control that calls the javascript is of type 'submit'. Sorry I cant offer more detail than this."

javascript the most misunderstood language



when you get started with javascript ,when you open some programs in browser let us say (mozilla firefox) some of them will work in mozilla firefox and some others are not.
Why is it so?
one of the reason is due to its rendering engine
and one more thing you should know something about the history of javascript.
Intially javascript called as livescript was developed by Netscape navigator.At that time java was popular ,so they named it as javascript.Microsoft saw this programming language and they reengineered it and come up with their own programming language called jscript which is similar to javascript but differs in certain features.so in order to standardize their model netscape navigator went into Ecma (european computer manufacturers association ) and it is called as ECMAscript which is nothing but javascript.

Ever wondered what is about:config ?



Ever wondered what is about:config ?
Ever wondered how to change default search engine of your browser ?
source:
http://vinodjayachandran.blogspot.com/
Iam a die hard fan firefox and google. As I simple love google, so do I with chrome too, inspite of many pit falls in it. See certain amazing features of chrome, such as speed dial, frequently visited websites , search from address bar etc, It attracted me more to chrome than firefox. But one of the most annoying part was, chrome used to hang quite often for me. I used to wonder, how firefox, could compromise on such special amazing features.

Although all these computer stuffs interests me as I am a computer science engineer, I am not a geek in it and often my laziness over rules me , which prevents me to explore new things. But fortunately always to my rescue, I have a computer nerd with me for the past 3 yrs.

This friend of mine is a lover of google too, but only difference between me and him is, he knows to use google better. He explored and let me know various Add ons in Firefox, which has just the same and equal functionality of that of chrome. I was amazed to have all those features in my all time favourite Firefox.

The other day, I installed Yahoo messenger and that crazy thing installed yahoo tool bar and changed various other settings in my browser and the most annoying part was, it made my default search engine as yahoo. So when ever , i used to type any search expression in my address bar, it started doing yahoo search. Atleast in search, i can't compromise google. It was very annoying and I literally felt handicapped. It reduced my productivity too to a real gr8 extent. I took all the pains to change the default search engine, explored all the menu options of the browser , but couldn't succeed. Then I had no other option , than to reach out to my computer nerd for help. In no time, he gave me a perfect solution, which solved lot other problems of mine and gave me a sense of relief.

I would like share with you all , the perfect solution which my friend gave me, which not only helps you to change the default search engine of your browser, instead lot other features of your browser.

1) On your address bar type about:config.
2) It will take you to a warning message. Accept it and proceed ahead to change the advanced settings of your browser.
3) On Top, you can find a Text Field named "Filter". Type Keyword.URL. You can see the value of this attribute in the right most column.
4) Double click on it to update the value. Initially it was yahoo for me and you can update it to http://www.google.com/search?q= for google.

This one is just one single example. Similarly one can play around with so many other attributes of browser to change the setting of browser through about:config.

I was impressed and it motivated me to share it with the Internet world too, for people who don't know. I whole heartedly dedicate this blog, to my friend. For those who know me , would quite obviously know my friend too, who has been sharing my room for the past 3 yrs.

Love vs Money Another nice story which I came across



A small touching story mainly for professionals. ..A reminder..
A man came home from work late, tired and irritated, to find his
5-year old son waiting for him at the door.
SON: "Daddy, may I ask you a question?"
DAD: "Yeah sure, what is it?" replied the man.
SON: "Daddy, how much do you make an hour?"
DAD: "That's none of your business. Why do you ask such a thing?"
the man said angrily.
SON: "I just want to know. Please tell me, how much do you make an
hour?"
DAD: "If you must know, I make Rs.100 an hour."
SON: "Oh," the little boy replied, with his head down.
SON: "Daddy, may I please borrow Rs.50?"
The father was furious, "If the only reason you asked that is so you
can borrow some money to buy a silly toy or some other nonsense, then
you march yourself straight to your room and go to bed. Think about
why you are being so selfish. I work hard everyday for such this
childish behavior."

The little boy quietly went to his room and shut the door.
The man sat down and started to get even angrier about the little
boy's questions. How dare he ask such questions only to get some
money?

After about an hour or so, the man had calmed down, and started to
think: Maybe there was something he really needed to buy with that
Rs.50 and he really didn't ask for money very often. The man went to
the door of the little boy's room and opened the door.
"Are you asleep, son?" He asked.
"No daddy, I'm awake," replied the boy.
"I've been thinking, maybe I was too hard on you earlier" said the
man.
"It's been a long day and I took out my aggravation on you.. Here's the
Rs.50 you asked for."
The little boy sat straight up, smiling. "Oh, thank you daddy!" He
yelled.

Then, reaching under his pillow he pulled out some crumpled up bills.
The man saw that the boy already had money, started to get angry
again. The little boy slowly counted out his money, and then looked up
at his father.
"Why do you want more money if you already have some?" the father
grumbled.
"Because I didn't have enough, but now I do," the little boy replied.
"Daddy, I have Rs.100 now. Can I buy an hour of your time?
Please come home early tomorrow. I would like to have dinner with
you."
The father was crushed. He put his arms around his little son, and he
begged for his forgiveness.
It's just a short reminder to all of you working so hard in life. We
should not let time slip through our fingers without having spent some
time with those who really matter to us, those close to our hearts.
Do remember to share that Rs.100 worth of your time with someone you love.
If we die tomorrow, the company that we are working for could easily
replace us in a matter of days.
But the family & friends we leave behind will feel the loss for the
rest of their lives. And come to think of it, we pour ourselves more
into work than to our family.

Things that you should be aware of before doing javascript



As you know html is a lenient programming language.you can do mistakes.But anyhow the browser will display the content.But how it will behave is an absurd one.
But when you come into javascript even when you make a small mistake ,you won't even get the undesired output.What I mean by that.It is very difficult to debug your javascript programs.In order to debug your javascript programs you should have exposure about the following addons and opensource software.
https://addons.mozilla.org/en-US/firefox/addon/1843/
https://addons.mozilla.org/en-US/firefox/addon/60/
https://addons.mozilla.org/en-US/firefox/addon/6622/
http://www.aptana.com/
you will be able to realise the features of the above when you started studying javascript.

what is javascript?



I think that everyone have little knowledge about html.It is the abbreviation of Hypertext markup language.As you know it is just the template in order to make it an efficient one you have to add something to the template.It will be clear to those who have studied software engineering.So stop this thing and now lets us now start exploring what is meant by javascript.
Before jumping into any topic you should ask three ???
why is it needed?
How is it applied?
where is it applied?
ok I will answer these questions one by one.The html is just nothing but a static page.you can't do many things by using html alone.What I mean by that.You are creating a page that will be merely display the content without any additional features.The main purpose of javascript is to add interactivity to the user who are the resources for your site.
javascript=html +Business logic
what is meant by business logic.
Business logic is just nothing but how you want to model the content.
The special benefits of javascripts are
1)you can perform form validation in client side so that you can decrease the load on server side.
2)The important thing is you can dynamically create objects.Here objects are nothing but html elements.
The mother of javascript is Dom(Document object model).What I meant by that ?.You will understand later in detail.

Nice story which I come across



The Attitude (Story)

****************
A little boy went into a drug store, reached for a soda carton and ask him for a Phone Call.
Shop-owner replied Sweety this is no a STD, but you can do one call.

The store-owner observed and listened to the conversation:
The boy asked, "Lady, Can you give me the job of cutting your lawn?
The woman replied, "I already have someone to cut my lawn."
"Lady, I will cut your lawn for half the price of the person who cuts your lawn now." replied boy.
The woman responded that she was very satisfied with the person who was presently cutting her lawn.
The little boy found more perseverance and offered, "Lady, I'll even sweep your curb and your sidewalk, so on Sunday you will have the prettiest lawn in all of North-Palm beach, Florida."
Again the woman answered in the negative.
With a smile on his face, the little boy replaced the receiver.
The store-owner, who was listening to all this, walked over to the boy and said," Son... I like your attitude; I like that positive spirit and would like to offer you a job."
The little boy replied, "No thanks, I was just checking my performance with the job I already have. I am the one who is working for that lady, I was talking to!"

Funny illustration of webtechnology related concept



Hi guys this is my own thinking.I just thought of linking webtechnology with Human life.
These are the assumptions to be made before going to the proof
You-the html template(since everything happening between yourself)
Your brain-the mysql server
Your Behaviour-javascript
Various thoughts associated to your Behaviour-Dom
Your presentation-css
Your reflex action-ajax
Proof
You are the Html template .Everything happening inside you .The way you look,how do you recognized in society is nothing but css.The way you respond to others reactions in a dynamic way is nothing but your javascript.The various thoughts that arises when you thought of doing something that have various bondages between them which preserve hierarchial like structure is nothing but Dom(Document object model)
e.g

Your Brain is nothing but an Mysql server which have tons of data like thoughts,visual images.In order to fetch the data from an MySql server(Brain) you need a language (stimulation,the thing which stimulates you ) called php .your reflex action is nothing but Ajax .As you know reflex action is nothing but some sudden immediate reaction which happens in notime

where Indian System is lacking in Education compared to Western style



You may think that I'm going out of the topic but at the end you will realize that i am in a proper track.
how to become a master at anything (that you had given up thinking that it might not be possible)
how some people are good at something and some are not.Why is it so?
Is it predtermined that everyone fate has been determined before they born?
I think it is not .
The three things that are needed to excel at one thing is
(1)It's all about passion.

(2) first before started doing anything ,you should know it's application .Then only you will get some attraction towards it.
3)last but not least .
practice makes a man perfect
Also
there is no pains,no gains
Once you realize this you can achieve anything you want.
Always remember this thing
"If you are getting anything without an hardwork ,you won't get an permanent satisfaction (means you will act in front of others that you are apt for that but there always an innerwaves arises within you).
So try hard with some passion you will get anything you want so everything is possible
apply input (hardwork with passion)=>process(trim im from (impossible))=>will give the output possible.
So I conclude by saying that our education system is lacking in three essential things
they are
(1)application(where it is applied and how it is applied and why is it applied.Most needed but it is not provided)
(2)exposure about the things
(3)visualization(the most needed thing for all)
