Java Script III
















JavaScript can be used to validate data in HTML forms before sending off the content to a server.
Form data that typically are checked by a JavaScript could be:
  • has the user left required fields empty?
  • has the user entered a valid e-mail address?
  • has the user entered a valid date?
  • has the user entered text in a numeric field?

The idea behind JavaScript form validation is to provide a method to check the user entered information before they can even submit it. JavaScript also lets you display helpful alerts to inform the user what information they have entered incorrectly and how they can fix it. In this lesson we will be reviewing some basic form validation, showing you how to check for the following:

If a text input is empty or not
If a text input is all numbers
If a text input is all letters
If a text input is all alphanumeric characters (numbers & letters)
If a text input has the correct number of characters in it (useful when restricting the length of a username and/or password)
If a selection has been made from an HTML select input (the drop down selector)
If an email address is valid
How to check all above when the user has completed filling out the form

71.JavaScript Statements


JavaScript Statement
The JavaScript language supported Two type Condition.
 1.if statement
 2.Function

if Statement
The if statement is used  to make decisions in JavaScript. Boolean operators are also used in along with the if statement. The if statement is  the most used features of JavaScript. It is basically the same in JavaScript as it is in other programming languages.

Example

<HTML>
<HEAD>
</HEAD>
<SCRIPT language="JavaScript">
<!--
var num = 10
if(num == 10)
{
document.write("<B>Statement!</B><BR>")
}
//--></SCRIPT>
my program successfully completed

</BODY>
</HTML>
Function
The function keyword identifies as a function. The parameters in the parenthesis ( ) provide a means of passing values to the function. There can be as many parameters separated by commas as you need. This is perfectly ok to have a function with no parameters. These parameters are variables which are used by the JavaScript statements inside the curly braces { }. The variable keyword is not needed to declare the parameters in a function as variables because they are automatically declared and initialized when the function is called. The function can return a value by using the return keyword.

Example
<HTML>
<HEAD>
</HEAD>
<script languane="JavaScript">

function prod(a,b)
{
var x=a*b
return x;
}

var mul=prod(2,5);
document.write("multipication:"+mul);
</script>
</BODY>
</HTML>

Conditional JavaScript if-else Statement
The JavaScript Conditional Statement used to different  actions and used to  based on different conditions. you want to execute some code if a condition is true and another code the condition is not true, use the if....else statement.

Example

<HTML>
<HEAD>
</HEAD>
script type="text/javascript">
var a = new Date()
var time = a.getHours()
if (time < 20)
{
document.write("Good morning!")
}
else
{
document.write("Good day!")
}
</script>
</BODY>
</HTML>

70.SEO Killers - Duplicate Content, Spam and Filler


You have a handle on what modern SEO content should be, but it's also vital to understand what it shouldn't be. Nielsen's research described what kept readers on web sites and shed light on what drove them away. Search engines take these same factors into account and rank pages down or even remove them from ranking altogether.
Duplicate content can sink a site. Even legally obtained duplicate content such as articles linked whole from news feeds and large blocks of attributed quotes diminish a site's SEO value. Readers have no reason to visit a site that gives them other sites' news verbatim. Page ranks will decline over time without original content.
While you don't want large blocks of duplicate content on your site, you want the timely information that your news feeds deliver. Build fresh new content on the foundation of other information whenever possible. It takes more effort to assimilate and summarize a news story or to use it as a link within an original article, but doing so will cast your site in a more positive light. If you add sufficient value with sharp writing and relevant links, you'll find yourself in the search engine stratosphere.
The old method of following keyword formulas and meeting keyword percentages is not only outdated, it will actively lower your site's rank. Heavy keyword-loading is the hallmark of advertising web sites, and search engines know it. Using related words and relevant phrases to enhance topic recognition marks your site as valuable and drives its search engine value higher. Varied writing is also more readable to your human visitors.
Nielsen found that human readers shunned sites full of filler phrases. Clear, concise web writing has greater value than sprawling pages full of fluff. Hyperbole and promotional language -- describing a product as "the best ever" or "the perfect solution," for example -- contributes nothing to the meaning of the text. Human readers filter out fluff and software ranks down sites with too much of it, so eliminate it from your site.
Search engines change their algorithms regularly in an effort to provide their users with more relevant results. The state of SEO art changes with them. The only constant in web writing is its human audience. Pages that provide novel, appealing content in a reader-friendly format will rise to the top of the rankings.

69.Six Sigma Model


Six Sigma is a set of practices originally developed by Motorola to systematically improve processes by eliminating defects. A defect is defined as nonconformity of a product or service to its specifications.

While the particulars of the methodology were originally formulated by Bill Smith at Motorola in 1986, Six Sigma was heavily inspired by six preceding decades of quality improvement methodologies such as quality control, TQM, and Zero Defects. Like its predecessors, Six Sigma asserts the following:

Continuous efforts to reduce variation in process outputs is key to business success

Manufacturing and business processes can be measured, analyzed, improved and controlled

Succeeding at achieving sustained quality improvement requires commitment from the entire organization, particularly from top-level management

The term "Six Sigma" refers to the ability of highly capable processes to produce output within specification. In particular, processes that operate with six sigma quality produce at defect levels below 3.4 defects per (one) million opportunities (DPMO). Six Sigma's implicit goal is to improve all processes to that level of quality or better.

Six Sigma is a registered service mark and trademark of Motorola, Inc. Motorola has reported over US$17 billion in savings from Six Sigma as of 2006.

In addition to Motorola, companies that adopted Six Sigma methodologies early on and continue to practice it today include Honeywell International (previously known as Allied Signal) and General Electric (introduced by Jack Welch).

Recently some practitioners have used the TRIZ methodology for problem solving and product design as part of a Six sigma approach.

68.JavaScript II


Knowing that javascript needs to be entered between <script> tags, is a start. But there are a few other things you need to know before writing your first javascript:
Javascript lines end with a semicolon.
You may have noticed from the example on the previous page that javascript lines end with a semicolon.
You can easily put all your javascript on a single line without destroying the performance of it.
However, you would destroy the overview of your script so it is not advisable.

Always put the text within " ".
When entering text to be handled by javascript, you should always put the text within " ".
If you forget to enclose your text in " ", javascript will interpret your text as being variables rather than text.
In the next section you will learn why this would cause an error to your script.

Capital letters are different from lowercase letters.
You should always remember that capital letters are different from lowercase letters.
This means that when you write commands in javascript, you need to type capital letters in the correct places, and nowhere else.

Incorrect capitalization is probably the most common source of error for javascript programmers on all levels!!

Now consider this example:

Instead of having javascript write something in a popup box we could have it write directly into the document.

<html>
<head>
<title>My Javascript Page</title>
</head>

<body>
<script>
document.write("Welcome to my world!!!");
</script>
</body>
</html>

The document.write is a javascript command telling the browser that what follows within the parentheses is to be written into the document.

Note: When entering text in javascript you need to include it in " ".

The script in the example would produce this output on
your page:

Welcome to my world!!!

Consider this example to learn where javascript writes the text:

<html>
<head>
<title>My Javascript Page</title>
</head>

<body>
Hello!!!<br>
<script>
document.write("Welcome to my world!!!<br>");
</script>
Enjoy your stay...<br>
</body>
</html>

The output from this example would look like this:

Hello!!!
Welcome to my world!!!
Enjoy your stay...

As you can see, javascript simply writes the text to where the script is placed within the HTML codes.

An interesting aspect is that you can write all kinds of HTML tags to webpages with the document.write method.

For instance, if you wanted to make a long table that compared Fahrenheit and Celsius, instead of actually typing all the values into the table, you could have javascript calculate the values and write the table to the document.

An example of a javascript generated table can be seen on the page explaining the hexadecimal colorsytem.
On that page, there are 15 tables with 25 columns in each.
Each cell shows different mixtures of the basic colors red, green and blue.

To set up these tables in HTML would demand almost an entire days work. Using javascript for the same purpose took less than 15 minutes!

67.Writing SEO Content for Search Engines


SEO no longer means scattering keywords like Hansel and Gretel throwing breadcrumbs. The newest search engines scan pages almost as your readers might. Jakob Nielsen, a researcher and expert in human-machine interaction at the Technical University of Copenhagen, found that almost 80 percent of a web site's visitors scanned the page rather than reading it line by line. They spent their first fractions of a second on the page deciding if it was worth their time. Search engine programmers still use this research to devise algorithms that provide more organic and meaningful rankings.
The same things that catch a visitor's eye will get a search engine's attention. The upper left corner of the page is the most valuable real estate on the page, as it's where a reader's eyes go first. Put important text there so search engines and people will see it immediately. It's also a good spot for boxed text and itemized lists, both of which appeal equally to carbon-based and silicon-based brains.
Bold text makes people and machines notice, but use those tags judiciously. Too much bold text looks like an advertisement and will cause search engines to devalue your site. Italic text bold HTML tags should surround meaningful concepts, not emphasis words. Bolding a "very" or italicizing a "more" means nothing to a search engine, so apply those tags to important concepts and sub-headings.
Searches now look for associated terms and relevant phrases, not just keywords. A person picks up meaning from context and readily distinguishes the term "clipping" as it applies to hair from the same word as it refers to film stock or video game graphics. Let your visitors -- human and machine -- know whether you're talking about German shepherds as a dog breed or as an exciting career in European wool and mutton. In your SEO text, include synonyms and relevant terms to let search engines recognize the purpose of your site.
Happily, there's a way to work these terms into your content without monitoring keyword and keyphrase percentages: simply write the kind of engaging copy that people like to read. If you write for readers, the search engines will follow.




You have a handle on what modern SEO content should be, but it's also vital to understand what it shouldn't be. Nielsen's research described what kept readers on web sites and shed light on what drove them away. Search engines take these same factors into account and rank pages down or even remove them from ranking altogether.
