Javascript (no relation to Java) is a text base language used with HTML. It is used for client side manipulation. For instance, if you set up a form where the user has to fill in a name, you can create a javascript that checks to make sure they do and won't let them submit the page until they do.

The concept behind Javascript programming was a way to provide some logic programming on the client side rather than on the server. Since it takes time to send a request to the server, process, and then receive a response, if the user can handle some of the processing itself it would have multiple advantages including...\n\n1) Speed... saves time to do the programming on the client rather than asking the server.\n\n2) Reduces load on the server. The server can work on its own logic and handle requests from multiple people rather than having to run code for everyone.\n\n3) You can write more exclusive code to target the individual user. Javascript makes it easier for the programmer to write code that deals with this one particular user rather than worrying about keeping track of users and making it generic for everyone.\n\nThose are the primary goals of the scripting language. In combination with server side scripting and methods like AJAX, you can get more of a complete solution for the user's experience.\n\nHope this helps!

ya in javascript\nthis is the code\n\n<html>\n<HEAD>\n\n<SCRIPT LANGUAGE="JavaScript1.1">\n\nfunction right(e) {\nif (navigator.appName == 'Netscape' && \n(e.which == 3 || e.which == 2))\nreturn false;\nelse if (navigator.appName == 'Microsoft Internet Explorer' && \n(event.button == 2 || event.button == 3)) {\nalert("Sorry, you do not have permission to right click.");\nreturn false;\n}\nreturn true;\n}\n\ndocument.onmousedown=right;\ndocument.onmouseup=right;\nif (document.layers) window.captureEvents(Event.MOUSEDOWN);\nif (document.layers) window.captureEvents(Event.MOUSEUP);\nwindow.onmousedown=right;\nwindow.onmouseup=right;\n\n</script>\n</HEAD>\n\n\n\n<BODY>\n\n<center>[ Try right-clicking the image and then the text link below ]\n\n\n\n\n</body>\n</html>

"return false" means that the code run without errors. Function can be used to return a value, meaning if you write something like this\n\nfunction someFunction() {\na = otherFunction();\n}\nfunction otherFunction() {\nreturn 2;\n}\n\nand you call the someFunction function, variable a will now contain the otherFunction's return value, which is 2.\n\nSome people have the habits to use this to return that the function has finished succesfully without errors, so denoting that the code is run till the end. If the script writer feel that the code might have some error when run and has anticipated it, he would then return some other thing than false, like return 3, meaning it has code 3 error.\n\nNote: in JS, false is equal to 0, while true is 1.\n\nabout the ; sign. It is Javascript end-of-line/line continuation character. Some people might want to write:\n\nalert('An onMouseOver event');return false\n\nit is the same as\n\nalert('An onMouseOver event');\nreturn false;\n\nor \n\nalert('An onMouseOver event')\nreturn false\n\nThe ; means that the line ends there and whatever follows next should be run like in a new line.\n\nThis is often used on functions that would like to be written in one line and one line is most of the time, neccesary for an event caller (like onmouseover).

why write one when there are literally hundreds out there on the web that already do this?\n\nhttp://internet.javascript.com has a lot.

The JavaScript right now has 2 parts, the server side and also the client side ( this is what it was originally designed for ).\n\nSo it already has come a long way than the one it was originally designed by Netscape Programmers. I think it might become more pattern matching language on client side and some kind of an XML like language to support self created structured data. As every application now a days is becoming more date intense, some day they might want to use JavaScript in small hand held smart devices.\n\nEven though JavaScript code can be crunched by a proxy and converted to XML as of today's technology, we might want to make this language more efficient and then enable it on smart devices.\n\nEnjoy.

Hi,\n\nYou could take a look at the dom basics from the link:\nhttp://www.howtocreate.co.uk/tutorials/javascript/dombasics\n\nIt will explain better than I would :) And it has enriched information.\n\nGood Luck

Sometimes, JavaScript / VBScript used by an application has errors in it. That's what this message is telling you.\n\nSomewhere, in your system tray, is a widget -- a printer utility, or some gizmo of some sort -- that is causing the problem. Your best bet: start turning them off one at a time until you find the offender.

When you code your webpage in HTML you need to do some coding in JavaScript. \n\nThe following code should help.\n<html>\n<head>\n<script>\nfunction openWindow()\n{\nprompt("Welcome to my site")\n\n}\n</script>\n</head>\n<body onload "openWindow()">\nContent of webpage\n</body>\n</html>\n\nThis will successfully give you a prompt message box.\n\nHope that helps

Asynchronous JavaScript And XML, or its acronym, Ajax, is a Web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire Web page does not have to be reloaded each time the user makes a change. This is meant to increase the Web page's interactivity, speed, and usability.\n\nThere is no such thing as AJAX software. Ajax is javascript combined with xml and php/asp/etc. Its just a buzz word that means a combination of tecnologies.

Javascript itself is a scripting language. You can call a function name alert to show popup messages in javascript.
