如何将字符串转换为JavaScript日期对象?
var st = "date in some format"
var dt = new Date();
var dt_st = // st in Date format, same as dt.

你可以试试这个:
function formatDate(userDOB) { const dob = new Date(userDOB); const monthNames = [ 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' ]; const day = dob.getDate(); const monthIndex = dob.getMonth(); const year = dob.getFullYear(); // return day + ' ' + monthNames[monthIndex] + ' ' + year; return `${day} ${monthNames[monthIndex]} ${year}`; } console.log(formatDate('1982-08-10'));
其他回答
function stringToDate(_date,_format,_delimiter)
{
var formatLowerCase=_format.toLowerCase();
var formatItems=formatLowerCase.split(_delimiter);
var dateItems=_date.split(_delimiter);
var monthIndex=formatItems.indexOf("mm");
var dayIndex=formatItems.indexOf("dd");
var yearIndex=formatItems.indexOf("yyyy");
var month=parseInt(dateItems[monthIndex]);
month-=1;
var formatedDate = new Date(dateItems[yearIndex],month,dateItems[dayIndex]);
return formatedDate;
}
stringToDate("17/9/2014","dd/MM/yyyy","/");
stringToDate("9/17/2014","mm/dd/yyyy","/")
stringToDate("9-17-2014","mm-dd-yyyy","-")
Var a = "13:15" var b = toDate(a， "h:m") / /警报(b); document . write (b); 函数toDate(dStr, format) { var now = new Date(); If (format == "h:m") { now.setHours(下游。substr (0, dStr.indexOf(“:”))); now.setMinutes(dStr.substr(dStr.indexOf(":") + 1)); now.setSeconds (0); 现在返回; 其他} 返回“格式无效”; ｝
转换为pt-BR格式:
var dateString = "13/10/2014";
var dataSplit = dateString.split('/');
var dateConverted;
if (dataSplit[2].split(" ").length > 1) {
var hora = dataSplit[2].split(" ")[1].split(':');
dataSplit[2] = dataSplit[2].split(" ")[0];
dateConverted = new Date(dataSplit[2], dataSplit[1]-1, dataSplit[0], hora[0], hora[1]);
} else {
dateConverted = new Date(dataSplit[2], dataSplit[1] - 1, dataSplit[0]);
}
我希望能帮助到别人!!
你可以试试这个:
function formatDate(userDOB) { const dob = new Date(userDOB); const monthNames = [ 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' ]; const day = dob.getDate(); const monthIndex = dob.getMonth(); const year = dob.getFullYear(); // return day + ' ' + monthNames[monthIndex] + ' ' + year; return `${day} ${monthNames[monthIndex]} ${year}`; } console.log(formatDate('1982-08-10'));
新的日期(2000,10,1)将给你“星期三11月1日2000 00:00:00 GMT+0100 (CET)”
0表示month，表示1月
