我想知道如何在jQuery中使用Date()函数以yyyy/mm/dd格式获取当前日期。


当前回答

这是我只用jQuery得出的结果。只是把碎片拼在一起的问题。

        //Gather date information from local system
        var ThisMonth = new Date().getMonth() + 1;
        var ThisDay = new Date().getDate();
        var ThisYear = new Date().getFullYear();
        var ThisDate = ThisMonth.toString() + "/" + ThisDay.toString() + "/" + ThisYear.toString();

        //Gather time information from local system
        var ThisHour = new Date().getHours();
        var ThisMinute = new Date().getMinutes();
        var ThisTime = ThisHour.toString() + ":" + ThisMinute.toString();

        //Concatenate date and time for date-time stamp
        var ThisDateTime = ThisDate  + " " + ThisTime;

其他回答

function GetTodayDate() {
   var tdate = new Date();
   var dd = tdate.getDate(); //yields day
   var MM = tdate.getMonth(); //yields month
   var yyyy = tdate.getFullYear(); //yields year
   var currentDate= dd + "-" +( MM+1) + "-" + yyyy;

   return currentDate;
}

非常方便的功能使用,享受。你不需要任何javascript框架。它只是在简单的javascript工作。

试试这个…

var d = new Date();
alert(d.getFullYear()+'/'+(d.getMonth()+1)+'/'+d.getDate());

getMonth()返回月份0到11,因此我们希望添加1来表示准确的月份

使用纯Javascript,你可以创建自己的YYYYMMDD格式原型;

Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
  var dd  = this.getDate().toString();
  return yyyy + "/" + (mm[1]?mm:"0"+mm[0]) + "/" + (dd[1]?dd:"0"+dd[0]); // padding
};

var date = new Date();
console.log( date.yyyymmdd() ); // Assuming you have an open console

Moment.js让它变得非常简单:

moment().format("YYYY/MM/DD")

当元素只有一个符号时,该对象设0:

function addZero(i) {
    if (i < 10) {
        i = "0" + i;
    }
    return i;
}

该对象设置实际的完整时间,小时和日期:

function getActualFullDate() {
    var d = new Date();
    var day = addZero(d.getDate());
    var month = addZero(d.getMonth()+1);
    var year = addZero(d.getFullYear());
    var h = addZero(d.getHours());
    var m = addZero(d.getMinutes());
    var s = addZero(d.getSeconds());
    return day + ". " + month + ". " + year + " (" + h + ":" + m + ")";
}

function getActualHour() {
    var d = new Date();
    var h = addZero(d.getHours());
    var m = addZero(d.getMinutes());
    var s = addZero(d.getSeconds());
    return h + ":" + m + ":" + s;
}

function getActualDate() {
    var d = new Date();
    var day = addZero(d.getDate());
    var month = addZero(d.getMonth()+1);
    var year = addZero(d.getFullYear());
    return day + ". " + month + ". " + year;
}

HTML:

<span id='full'>a</span>
<br>
<span id='hour'>b</span>
<br>    
<span id='date'>c</span>

JQUERY的观点:

$(document).ready(function(){
    $("#full").html(getActualFullDate());
    $("#hour").html(getActualHour());
    $("#date").html(getActualDate());
});
