i had done with javascript. Its not enough for making a geekness with that, but only for making the first lessons of javascript ...What is javascript ?
JavaScript is a scripting language that will allow you to add real programming to your webpages. You can create small application type processes with JavaScript, like a calculator or a primitive game of some sort. Important uses of javascript are
- Browser Detection
- Detecting the browser used by a visitor at your page. Depending on the browser, another page specifically designed for that browser can then be loaded.
- Cookies
- Storing information on the visitor's computer, then retrieving this information automatically next time the user visits your page. This technique is called "cookies".
- Control Browsers
- Opening pages in customized windows, where you specify if the browser's buttons, menu line, status line or whatever should be present.
- Validate Forms
- Validating inputs to fields before submitting a form. An example would be validating the entered email address to see if it has an @ in it, since if not, it's not a valid address.
where is the playground ?
The browser will use the
<script type="text/javascript"> and </script> to tell where javascript starts and ends respectively.
The <script> …… </script> Tag can be included in
- <head> section
- <body> section
- Both <head> section and <body> section
- In an External file with .js extension
- Eg : <script type="text/javascript" src="xxx.js"></script>
To declare a variable in JavaScript, use the var command. Eg : var state, city, zip, country;
Basics- Write directly into the document.
- Write using POPUP Boxes
>> alert("Welcome to my world!!!");
Confirm Box
>>if (confirm("Do you agree"))
{alert("You agree")}
else{alert ("You do not agree")};
Prompt Box
>> username=prompt("Please enter your
name","Enter your name here");
