How to convert string date in JavaScript

Question

I have string like this:

 "/Date(1388521800000)/"

How would I convert it to "YYYY-MM-DD"?

Answer 1

If the String always looks the same I would parse it like this:

String date = "/Date(1388521800000)/";
String stamp;

stamp = date.substring(date.indexOf("(")+1, date.indexOf(")"));

Answer 2

you can use this function to parse such date.

function fnParseDate(dateString)
{
    if (typeof dateString == 'object' && dateString instanceof Date) // It's already a JS Object (Of Date Type)
        return dateString; // No need to do any parsing. Return the original value.

    if (dateString.indexOf('/Date(') == 0) //Format: /Date(1320259705710)/
        return new Date(parseInt(dateString.substr(6), 10));

    alert('Given date is no properly formatted: ' + dateString);
    return new Date(); //Default value!
}

Answer 3

var sDate = "/Date(1388521800000)/";
var date = new Date(sDate.match(/\/Date\(([0-9]+)\)\//)[1]|0);
var formattedDate = date.getFullYear() + "-"+ 
                   (date.getMonth()<9?"0"+(date.getMonth()+1):date.getMonth()+1)+"-"+
                   (date.getDate()<10?"0"+date.getDate():date.getDate());
