This requires a jQuery UI .

Separate the string based on spaces. Take the parts and repair them.

 function convertDate(d){ var parts = d.split(" "); var months = {Jan: "01",Feb: "02",Mar: "03",Apr: "04",May: "05",Jun: "06",Jul: "07",Aug: "08",Sep: "09",Oct: "10",Nov: "11",Dec: "12"}; return parts[3]+"-"+months[parts[1]]+"-"+parts[2]; } var d = "Fri Jan 31 2014 00:00:00 GMT-0800 (Pacific Standard Time)"; alert(convertDate(d)); 

Answer 3

You can do it like this:

 var date = new Date("Fri Jan 31 2014 00:00:00 GMT-0800 (Pacific Standard Time)"); var year=date.getFullYear(); var month=date.getMonth()+1 //getMonth is zero based; var day=date.getDate(); var formatted=year+"-"+month+"-"+day; 

I see that you are trying to format the date. You should completely abandon this and use jQuery UI

You can format it so that

var str = $.datepicker.formatDate('yy-mm-dd', new Date("Fri Jan 31 2014 00:00:00 GMT-0800 (Pacific Standard Time)");

I found Notes for web developers useful in formatting dates

For such things, it is often useful to do a little testing in the browser console.

 var date = new Date("Fri Jan 31 2014 00:00:00 GMT-0800 (Pacific Standard Time)"); console.log(date.getFullYear() + '-' + date.getMonth()+1 + '-' + date.getDate()) 

Make sure you add + 1 to the getMonth () result, because it is based on a zero value.

Answer 5

You can also use the Moment.js library, do not forget to give it a search.

A few examples: moment().format('MMMM Do YYYY, h:mm:ss a');

 moment().format('dddd'); 

Answer 6

 A trifling refinement: var date = new Date(value); var year = date.getFullYear(); var rawMonth = parseInt(date.getMonth()) + 1; var month = rawMonth < 10 ? '0' + rawMonth : rawmonth; var rawDay = parseInt(date.getDate()); var day = rawDay < 10 ? '0' + rawDay : rawDay; console.log(year + '-' + month + '-' + day);
