Explain any 10 advantages of using JavaScript on Client side.?

Now a days there are a lots of things that you only can do from client-side with JavaScript. There are no alternet solutions. There are number of atributes that you can set with JavaScript which can't be set with anything else.

Not with javascript alone, I think. ActiveX would play an important part in accessing these components.

not problems , but its more secure , u had to add many sites to trusted sites , also mail , also java script may need some tune

Java is also a programming language like VB, VB.Net, C, C++. So you can make any applications like MS-Word, Excel, Power-Point in Java. The main advantage of java applications is they are platform independant. Means you can run them on any operating systems. MS-Word, Excel etc can run only on Windows OS. But Java Applications are sligtly slower then the application developed on Microsoft Platform like VB.Net, VB etc.\n\nBut to make an operating system you cannot use Java. Because Java is made for application programming not for system programming. For operating Systems you need lot of System Programming. C and C++ are the best language for system programming. So, to develop Operating Systems C, C++ are widely used. But only C and C++ are still not enough to make an OS. You also need Assembly Level programming but Java cannot be used to develop an OS.\n\nAJAX stands for Asynchronous JavaScript And XML. It can be used for online applications. GMail and Google Pages uses AJAX. Now AJAX is also used in Beta version of Yahoo Mail.\n\nTo know about AJAX, you have to understand the general procedure of web pages.\n\nConsider a web page containing a form which accepts the data of user information like first name, last name, address etc. and store it to the database and then after display a message like "Thank you for submitting your information..."\n\nNow you fill up the data and click on the submit button. Now the following procedure occurs\n\n1) Your data is sent to the web server.\n2) Data is stored in the database.\n3) After data is stored, web server gives back a web page containing a message like "Thank you for submitting your information..."\n4) Your web browser accepts the response from web server and display the page.\n\nHere, after clicking on submit button you have to wait until the data is stored and a new page is displayed.\n\nBut consider the example of Google Pages. In google pages during saving your page, the page is not refreshed. You can keep your editing page while your page is being saved. This happens because of AJAX.\n\nWith AJAX you can receive and send data from web server without refreshing the whole page.\n\nTo learn about AJAX, follow the link\nhttp://www.w3schools.com/ajax/default.asp\n\nThis can give you a basic idea of AJAX.

For client side application programs the hot stuff is anything .NET, preferably c# and even vc++.net is doing well. Java is really taking off too.\n\nFor server side web programming... PHP hands down is hot. Paired up with MySQL, that technology is really dominating. Perl is there, but slowly dying by the wayside.\n\nFor web development, AJAX and straight XML with a sprinkle of DHTML. Its the foundation of the Web 2.0 movement.\n\nBelieve me, I have my hands in all three of these categories and I often can't keep up with all the work people want to throw at me. I pretty much can command my own perks and salary because of it.\n\nHope I helped you out with this.

You can achive that via Server Side Scripting.

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.

Assuming the content is there, it must load quickly, have a consistent and user-friendly interface across the site, and the graphics and colors used should serve to highlight parts of the page, not obscure them. Jarring combinations and messy user interfaces turn off clients and make a page look unprofessional.\nAlso, stay away from scripting unless you can do it properly (this means layers of redundancy for those who turn off scripting or have it disabled by higher forces for security purposes. The site should be equally functional (although it may be less flashy) for these users as those with scripting turned on.)\nIn addition, do not use browser-specific HTML unless, again, you plan on using redundant "cross-browser" code to ensure consistent functionality. Try to implement as much of your site as possible in standard XHTML 1.0 (for future compatibility).

Hi,\nIt is quite a nice question. JAVASCRIPT cannot send email within a form. Javascript is just a client side language which does not have the capabilities of normal dynamic programming languages. \n\nYou must have alternatives of using serverside programming languages. You could use JSP/ASP/PHP/ROR/.NET etc to build a form that access a dynamic page. all the above languages can be incorporated within your existing project if and only if you have to enabled / installed on the server machine.\n\nIf your using PHP, then you have the mail() function that sends email... http://www.php.net/mail/\n\nTake care, good luck on what your doing :p

If you want to be more of a client side programmer, the following is a good list.\n\nJavaScript -- For client side interaction. Look up the term AJAX, which incorporates JavaScript, and you'll see all sorts of people talking about how this is the future of web applications. Gmail is an example of an AJAX application.\n\nCSS -- Not a scripting language, but a way to style and layout web pages. Alot of people use CSS wrong. There are a few books that cover how to do it right. Books by Eric Meyer (Eric Meyer on CSS 1 & 2) and Jeffery Zeldman (Web standards) are MUST READS if you want to learn it right in the shortest amount of time. You might work witha designer that will do all of this for you, but you still better understand it.\n\nHTML -- I'm sure you know this by know, but the trick is doing HTML right. The Zeldman book talks about this and the O'Reilly HTML reference book is very helpful. Don't fall into using HTML the wrong way since it is very hard to get out of that pit. When I say "wrong way", I mean using tables to layout your page instead of CSS or .\n\nXML -- Not really a scripting language, but you'll need to know how to use XML in relation to other scripting languages.\n\nXSL -- I have read a little about this, but don't really know how many companies are using it in the real world. There is a slight bit of scripting involved. Read up on it just to be aware. I still believe most people are sticking with HTML and CSS.\n\nFor backend programming, which I don't no much about,:\n\nASP or ASP.net -- If you end up working at a company using microsoft products, you'll need to know this. They are very similiar to PHP.\n\nSQL -- Not a scripting language, but you'll need to interface with databases and this is the only way. SQL syntax varies by the product you use. MYSQL, SQLServer, Oracle are all popular database products.\n\nVB or VB.net -- If you are in a microsoft shop, they'll want you to know this.\n\nC# and/or Java\n\nC++ -- If you want to get hard core.\n\nThere is definitely more stuff out there. I recommend looking at some job descriptions of jobs you might want and check out their requirements. That's the best way.

Check out my sources below. They highlight and break down into great detail the benefits of using AJAX.\n\n"AJAX has two huge benefits:\n\nSpeed and invisibility (ala smart client) makes for a very slick user experience. \nThe smaller server resources footprint helps server scalability (seriously!)."

The answer is, only if they've been designed well.  \n\nAjax is a useful technique because it can cut down on the number of times you need to wait for an entire page to load.  So, the website can get you what you need by only sending a small amount of information to you (only what has changed) rather than all the information required to render the whole page.  \n\nIf done correctly, a site built this way will "work more quickly".  But, it is entirely possible to design an application using Ajax that does not take advantage of this correctly.  You could make really, really slow applications with ajax too.

if I get it right, & you are looking for javascript to use with your wesite check this website: \n\nhttp://www.web-source.net\n\nit has many usefull javascript you can include in your site.

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.

There are piles of advantages. It's compiled, it's got great namespaces / objects, you can use just about any COM or COM+ object out there, it's compiled, it has certain AJAX-like features.
