[解決済み] dd/mm/yyyy の文字列を JavaScript の Date オブジェクトに変換するには？

var dateString = "10/23/2015"; // Oct 23

var dateObject = new Date(dateString);

document.body.innerHTML = dateObject.toString();

var dateString = "23/10/2015"; // Oct 23

var dateParts = dateString.split("/");

// month is 0-based, that's why we need dataParts[1] - 1
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]); 

document.body.innerHTML = dateObject.toString();

var dateString = "23/10/2015"; // Oct 23

var dateMomentObject = moment(dateString, "DD/MM/YYYY"); // 1st argument - string, 2nd argument - format
var dateObject = dateMomentObject.toDate(); // convert moment.js object to Date object

document.body.innerHTML = dateObject.toString();
