Credit Card Validation

// remove non-numerics
var v = "0123456789";
var w = "";
for (i=0; i < s.length; i++) { x = s.charAt(i); if (v.indexOf(x,0) != -1) w += x; } // validate number j = w.length / 2; if (j < 6.5 || j > 8 || j == 7) return false;
k = Math.floor(j);
m = Math.ceil(j) - k;
c = 0;
for (i=0; i 9 ? Math.floor(a/10 + a%10) : a;
}
for (i=0; i return (c%10 == 0);
}

Date Validation

function checkDate() {

var myDayStr = document.CheckDate.formDate.value;
var myMonthStr = document.CheckDate.formMonth.value;
var myYearStr = document.CheckDate.formYear.value;
var myMonth = new Array('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'); var myDateStr = myDayStr + ' ' + myMonth[myMonthStr] + ' ' + myYearStr;

/* Using form values, create a new date object
using the setFullYear function */
var myDate = new Date();
myDate.setFullYear( myYearStr, myMonthStr, myDayStr );

if ( myDate.getMonth() != myMonthStr ) {
alert( 'I\'m sorry, but "' + myDateStr + '" is NOT a valid date.' );
} else {
alert( 'Congratulations! "' + myDateStr + '" IS a valid date.' );
}

JavaScript Features

1. Browser support
To access flash content, you need to install flash plugin in your browser. But to use javascript, you don't have to use any plugin at all. This is because all browsers have accepted javascript as a scripting language for them and provides integrated support for it. All you need to do is to handle some of the tasks that are dependent on DOM (Document Object Model) of different browsers properly.

2. Can be used on client side as well as on server side
As javascript has access to Document object model of browser, you can actually change the structure of web pages at runtime. Due to this, javascript can be used to add different effects to webpages. On the other hand, javascript could be used on the server side as well. For example, in Alfresco which is a popular open source enterprise content management system, javascript is used in creating webscripts. This makes adding custom tasks to alfresco quite simple.

3. Functional programming language
In javascript, function could be assigned to variables just like any other data types. Not only that, but a function can accept another function as a parameter and can also return a function. You can have functions with no name as well. Clearly, this gives you the ability to code in functional programming style.

4. Support for objects
Javascript is an object oriented language. However, the way javascript handles objects and inheritance is bit different from conventional object oriented programming languages like Java. Due to this, javascript supports most of the object oriented concepts while being simple to learn and use.

JavaScript Tutorial

JavaScript is the Scripting language used to add functionality,Validtae forms,Communicate with the server and much more. JavaScript is an implementation of the ECMAScript language standard, primarily used in the form of client-side Script, implemented as part of a web browser in order to provide enhanced user interfaces and dynamic websites.

ECMAScript is the scripting language standardized by Ecma International in the ECMA-262 specification and ISO/IEC 16262. The language is widely used for client-side scripting on the web.

JavaScript was originally developed by Brendan Eich of Netscape in 1995 under the name Mocha,later LiveScript, and finally renamed to JavaScript.
