Window Manipulation in JavaScript

Window Manipulation in JavaScript

While opening windows in HTML is very handy, it’s also limiting; the browser controls how the window looks. You have no control over the size of the window or what the window looks like. Happily, JavaScript gives you this control.

Here’s how:

1 window.open("URL","name","features");

This statement opens a window with the URL that you list as the first parameter in the method call. Above it’s called ” URL,”

The second parameter of the method call is the window’s name. This is just like the name we saw in the last page. If you open a window and there’s already a window open with the same name, the URL in youropen statement will be sent to that open window.

The third parameter, features, is a list of the different components a window can have. It’s an optional parameter, so let’s do some examples with the first two parameters before checking out features.

Here are some examples of using JavaScript to open windows.

Javascript Tutor – Lesson 2

Variables.

What’s a variable? Let’s suppose x=5.

x is a variable. The statement x=5 declares that the value of x is now 5. Can x be something else? Sure, x=6. Now x equals 6. (Hence the name “variable”… it’s value can vary.)

Can a variable be something other than a number? Sure. How about x=”Joe”. Now x equals the string “Joe”. (A string by the way is a string of characters… and strings are always enclosed in quotes.)

Can the name of a variable be something other than a letter like x? Sure, myname=”Joe”. Simple.

How can we incorporate this new found knowledge into our function? Easy…

<html>
<head>
<title></title>

<script type="text/javascript">

function HelloWorld()
{
   myname = "Joe";
   alert(myname);
}

</script>

</head>
<body>

<a href="javascript:HelloWorld()">Hello</a>

</body>
</html>

(Note again that strings are always enclosed in quotes, but variables are not.)

What we have called is the alert method. Think of a method as a command. Javascript has many methods.

We could make it say Hello + variable…

<html>
<head>
<title></title>

<script type="text/javascript">

function HelloWorld()
{
   myname = "Joe";
   alert("Hello " + myname);
}

</script>

</head>
<body>

<a href="javascript:HelloWorld()">Hello</a>

</body>
</html>

JavaScript – Lesson 1. Concepts

JavaScript programming language was developed by Netscape in collaboration with Sun Microsystems and anansirovan in 1995. JavaScript is used to create interactive html-documents. Main areas of use of JavaScript:

Making pages dynamic, ie pages, the content of which may change after loading.

Verification of user forms.

Decision “local” tasks using scripts.

JavaScript-code – the basis of most Ajax-applications.

JavaScript allows you to create applications that run on the client side, ie These applications run on the user’s computer browser

Programs (scripts) are processed in this language interpreter built-in browser. Unfortunately, not all scripts are executed correctly in all browsers, so test your javascript-programs in different browsers. JavaScript is case sensitive, ie uppercase and lowercase letters of the alphabet are considered different characters. Before you start writing the script, you should be familiar with the basic concepts, such as literals, variables, and expressions.

cursor

cursor Ustanavlivaet cursor shape when it is within the cell. The cursor depends on the operating system and installed options.

Before you take the opportunity to alter the cursor, choose, and whether it will be used to the place. Many users of such changes can be misleading when, for example, instead of the traditional hand that appears when you hover over a link, there is something else. In most cases, it is better to leave everything as it is.
