A parameter is a variable from outside of the defined function on which the function will act. These values here are what the function will need to perform the actions in the function. Make sure that the values you pass in are in the correct order because the function will take them in and assign these values to the parameters in the parentheses of the function declaration. Once you pass values into your function, you can use them however you want within your function. Try it for yourself: When you click on the words below, a confirmation box will pop up and then the link will bring you to the top of the page.

If the condition is false, another set of statements can be executed through the use of the else keyword. The main idea behind if statements is embodied by the sentence: "If the weather's good tomorrow, we'll go out and have a picnic and Lisa will do cartwheels -- else, we'll stay in and Catherine will watch TV.

Parentheses are required around the condition. If condition evaluates to true, the statements in statements1 are executed. Multiple statements must be enclosed in braces.

Loops handle repetitive tasks extremely well, especially in the context of consecutive elements. Arrays immediately spring too mind here, since array elements are numbered consecutively. It would be quite intuitive and equally practical , for instance, to write a loop that added 1 to each element within an array.

Don't worry if this doesn't make a lot of sense now, it will, after you finish reading the tutorial. The two most common types of loops are for and while loops: for Loops A for loop constitutes a statement which consists of three expressions, enclosed in parentheses and separated by semicolons, followed by a block of statements executed in the loop. This definition may, at first, sound confusing. Indeed, it is hard to understand for loops without seeing them in action.

See the section on variables for more information. It is typically used to initialize a counter variable. This expression may optionally declare new variables with the var keyword. The condition is evaluated on each pass through the loop. If this condition evaluates to true, the statements in statements are performed.

When the condition evaluates to false, the execution of the for loop stops. This conditional test is optional. If omitted, the condition always evaluates to true. The increment-expression is generally used to update or increment the counter variable.

The statements constitute a block of statements that are executed as long as condition evaluates to true. This can be a single statement or multiple statements. Although not required, it is good practice to indent these statements from the beginning of the for statement to make your code more readable. Check out the following for statement.

It starts by declaring the variable i and initializing it to zero. The two can fill in for one another - using either one is only a matter of convenience or preference according to context. The loop then repeats, as long as the specified condition is true. If this condition evaluates to true, the statements in the succeeding block are performed. When condition evaluates to false, execution continues with the statement following statements.

Although not required, it is good practice to indent these statements from the beginning of the statement. The following while loop iterates as long as n is less than three.

These are important because they allow someone to browse your code and understand what the various functions do or what your variables represent.

Comments also allow you to understand your code if it's been a while since you last looked at it. In JavaScript, you can write both one-line comments and multiple line comments.

The notation for each is different though. This is not necessary though. The following are examples of comments in JavaScript. The usual approach in scripting language is to create a pattern called a regular expression which describes a set of characters that may be present in a string.

Dynamic patterns are created using the keyword new. Class String functions match pattern This function searches a matching pattern. Returns array holding the results. If the search is successful pattern1 is replaced with pattern2. If the match is successful, the index of the start of the match is returned. If the search fails, the function returns Returns an array holding the results of the operation.

Returns true if a match is found, otherwise returns false. Built in objects: The document object A document is a web page that is being either displayed or created. The document has a number of properties that can be accessed by JavaScript programs and used to manipulate the content of the page.

Write or writeln Html pages can be created using JavaScript. This is done by using the write or writeln methods of the document object. First, most commonly and probably most usefully, the data that is entered onto your form can be checked at submission. Second you can actually build forms through JavaScript. Example : Validate. The Date object JavaScript provides functions to perform many different date manipulation.

Some of the functions are mentioned below.

Date : Construct an empty date object. Date year, month, day [,hour, minute, second] :Create a new Date object based upon numerical values for the year, month and day. Optional time values may also be supplied.

Accepts values in the range 1 to Optionally also sets month and day values. Events: JavaScript is a event-driven system. Nothing happens unless it is initiated by an event outside the script. The table below shows event, event handler and the description about the event handler. One common request is for a way of validating the username and password.

Following program shows the validation of data which uses two frames, in one frame user is going to enter the data and in the other frame equivalent result is going to be displayed. Example JavaScript code for data validation Mypage. Markup is nothing but instructions, which are often called as tags. There are many languages which shows how the data is displayed but no one describes what the data is. This is the point at which XML enters.

XML is used to describe the structure of a document not the way that is presented. The first line is the processing instruction which tells applications how to handle the XML. It is also serves as version declaration and says that the file is XML. A well formed document is one which follows all of the rules of XML.

Tags are matched and do not overlap, empty elements are ended properly, and the document contains an XML declaration. Most of the markup in an XML document is element markup. Elements are surrounded by tags much as they are in HTML. Each document has a single root element which contains al of the other markup. Nesting tags: Even the simplest XML document has nested tags. Unlike HTML these must be properly nested and closed in the reverse of the order in which they were opened.

Case Sensitive: XML is case sensitive and you must use lower case for your markup. Empty tags: Some tags are empty, they dont have content. Control Information: There are three types of control information Comments processing instructions 32 document type declaration. The DTD is usually present in separate file, so that it can be used by many files.

They are well understood. There are plenty of tools that support DTD. There are two models commonly used for parsers i. SAX parsers are used when dealing with streams of data. This type of parsers are usually used with java. SAX-based parsers run quickly. They can build static documents, navigate and search through them, add new elements, delete elements, and modify the content of existing elements. The views XML document as trees. The DOM exposes the whole of the document to applications. It is also scriptable so applications can manipulate the individual nodes.

XSL basically transforms one data structure to another i. It thus played an important role in popularising use of the Internet. The advent of the Mosaic web browser helped to make the web much more usable, to include the display of images and moving images GIFs. The terms Internet and World Wide Web are often used without much distinction. However, the two terms do not mean the same thing. The Internet is a global system of interconnected computer networks. In contrast, the World Wide Web is a global collection of documents and other resources , linked by hyperlinks and URIs.

The web browser then initiates a series of background communication messages to fetch and display the requested page. In the s, using a browser to view web pages—and to move from one web page to another through hyperlinks—came to be known as 'browsing,' 'web surfing' after channel surfing , or 'navigating the Web'.

Early studies of this new behaviour investigated user patterns in using web browsers.

One study, for example, found five user patterns: exploratory surfing, window surfing, evolved surfing, bounded navigation and targeted navigation. The browser resolves the server name of the URL www. This lookup returns an IP address such as
