• javascript
• date

• Where does the date e from? The user, is it dynamically created to "today's" date (whenever it runs) or is it hard-coded? – David Thomas Commented Feb 18, 2015 at 4:28
• The date es from user who choose manual date . But i just need the year. – Rezha Velly Commented Feb 18, 2015 at 4:31

if you are sure that the format is dd-MM-YYYY then split the string and switch it then parse it as a date.

    var date = '18-02-2015';
    var input = date.split("-");
    var dateObject = new Date(input[2] +"-"+ input[1] +"-"+ input[0]);
    console.log(dateObject);

    var year = dateObject.getFullYear();
    //or without parsing simply
    var year = input[2];

One approach, taking advantage of HTML's <input type="date" /> element, is:

function findYearFrom() {
  // if it's not of 'type="date"', or it has no value,
  // or the value is equal to the default-value:
  if (this.type !== 'date' || !this.value || this.value === this.defaultValue) {
    // we return here
    return false;
  }

  // we get the value of the element as a date, and then
  // call getFullYear() on that value:
  console.log(this.valueAsDate.getFullYear());
  return this.valueAsDate.getFullYear();
}

// binding the named-function as the change event-handler
// for this element:
document.getElementById('demo').addEventListener('change', findYearFrom);

<input id="demo" type="date" value="2015-02-18" />

if you know that the format always is dd-mm-yyyy you can do

var date = "18-02-2015"    
var year = date.substring(date.lastIndexOf("-")+1)

Hope this helps.

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10){
    dd='0'+dd
} 
if(mm<10){
    mm='0'+mm
} 
var today = dd+'/'+mm+'/'+yyyy;  

Refer JS Fiddle here

Have you looked at http://momentjs./

This should work for you to get just the year.

var day = moment("18-02-2015", "MM-DD-YYYY");
console.log(day.format("YYYY"));

With RegExp:

var year = function(str) {
  return str.match(/\d{4}$/)[0]; // \d{4}, four digits group from the end
};

alert(year('18/02/2015'));
alert(year('02/18/2004'));

With slice():

var year = function(str) {
  return str.slice(-4);// get last four characters
};

alert(year('01/12/2015'));
alert(year('18/02/2004'));

If the date you're working with is simply a string, then all you're trying to do is get the last 4 characters of the string, which make up the year.

Assuming that the date is always in the format you listed, use slice():

var date = '18-02-2015';
var year = date.slice(-4);

If the date needs to be an integer type, then use this instead:

var year = parseInt(date.slice(-4));
