Objectives :

  • What are the differences between HTML4 & HTML5?
  • What is new in HTML5?
  • What is deprecated from HTML5?

Here are the key differences between HTML4 & HTML5:

HTML4

HTML5

DOCTYPE is much longer as HTML4 is based on SGML-based.

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01//EN”

DOCTYPE is required to enable standards mode for HTML documents.<!DOCTYPE html>

Audio and Video are not part of HTML4 specification.

Audio and Videos are integral part of HTML5 specifications e.g. <audio> and<video> tags.

Vector Graphics is possible with the help of technologies such as VML, Silverlight, Flash etc.

Vector graphics is integral part of HTML5 e.g. SVG and canvas.

It is almost impossible to get true GeoLocation of user browsing any website especially if it comes to mobile devices.

JS GeoLocation API in HTML5 helps identify location of user browsing any website (provided user allows it)

Browser cache can be used as temporary storage.

Application Cache, Web SQL database and Web storage is available as client side storage. Accessible using JavaScript interface in HTML5 compliant browsers.

Web Sockets are not available. Generally used mechanisms are long polling and streaming.

Full duplex communication channels can be established with Server using Web Sockets. Accessible using JavaScript interface in HTML5 compliant browsers.

Does not allow JavaScript to run in browser. JS runs in same thread as browser interface.

Allows JavaScript to run in background. This is possible due to JS Web worker API in HTML5.

Works with all old browsers

Most of modern browser have started supporting HTML5 specification e.g. Firefox, Mozilla, Opera, Chrome, Safari etc.

Enjoy coding now.

Objectives :-

* How to execute multiple functions on single HTML event?
* How to call multiple funtions on single HTML event?

Many time you may have faced this issue, you may need to call / execute multiple functions on single HTML event & you may have stucked there, stop working, changed the functionality, etc.

But now don’t worry about it anymore. Here is the Code to execute multiple functions on a single HTML event :-

<html>
<head>
<script type="text/javascript">
function Message1 ()
 {
 alert ("Message1");
 }
 function Message2 ()
 {
 alert ("Message2");
 }
</script>
</head>
<body>
<form name="NameTheForm">
<input type="Button" name="buttonName" onclick="Message1(); Message2()">
</form>
</body>
</html>

The above code will execute / call two functions on single HTML event. Here for example I have written two functions but you can write multiple functions & can call them to onclick event separated by semicolon (;) as shown above.
