在JavaScript中获取当前date和时间

我有一个脚本，在JavaScript中打印当前的date和时间，但DATE是错误的。 这里是代码：

 var currentdate = new Date(); var datetime = "Last Sync: " + currentdate.getDay() + "/"+currentdate.getMonth() + "/" + currentdate.getFullYear() + " @ " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds(); 

它应该打印18/04/2012 15:07:33和打印3/3/2012 15:07:33

任何帮助？ 谢谢

Answer 1

调用.getMonth()您需要添加+1以显示正确的月份。 Javascript计数总是从0开始（看这里检查为什么），所以调用.getMonth()可能会返回4而不是5 。

所以在你的代码中我们可以使用currentdate.getMonth()+1来输出正确的值。 此外：

• .getDate()返回月份的一天< – 这是你想要的
• .getDay()是Date对象的一个​​独立方法，它将返回一个表示当前星期几的整数（0-6） 0 == Sunday

所以你的代码应该是这样的：

 var currentdate = new Date(); var datetime = "Last Sync: " + currentdate.getDate() + "/" + (currentdate.getMonth()+1) + "/" + currentdate.getFullYear() + " @ " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds();

JavaScriptdate实例inheritance自Date.prototype。 您可以修改构造函数的原型对象，以影响由JavaScript Date实例inheritance的属性和方法

您可以使用Date对象的原型构造函数，并创build一个Date对象的新方法来返回今天的date和时间。 这些新的方法或属性将被Date对象的所有实例inheritance，因此，如果您需要重新使用此function，它将特别有用。

 // For todays date; Date.prototype.today = function () { return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear(); } // For the time now Date.prototype.timeNow = function () { return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds(); } 

您可以通过执行以下操作简单地检索date和时间：

 var newDate = new Date(); var datetime = "LastSync: " + newDate.today() + " @ " + newDate.timeNow(); 

或者直接调用这个方法，

 var datetime = "LastSync: " + new Date().today() + " @ " + new Date().timeNow(); 

Answer 2

要得到时间和date，你应该使用

  new Date().toLocaleString(); >> "09/08/2014, 2:35:56 AM" 

只能得到你应该使用的date

  new Date().toLocaleDateString(); >> "09/08/2014" 

只得到你应该使用的时间

  new Date().toLocaleTimeString(); >> "2:35:56 AM" 

或者，如果你只是想在美国英语的时间格式hh:mm没有AM / PM

  new Date().toLocaleTimeString('en-US', { hour12: false, hour: "numeric", minute: "numeric"}); >> "02:35" 

或英国英语

  new Date().toLocaleTimeString('en-GB', { hour: "numeric", minute: "numeric"}); >> "02:35"

Answer 3

如果你想真正的MySQL风格的date时间使用这个

2013/10/04 08:51:32

  function getDateTime() { var now = new Date(); var year = now.getFullYear(); var month = now.getMonth()+1; var day = now.getDate(); var hour = now.getHours(); var minute = now.getMinutes(); var second = now.getSeconds(); if(month.toString().length == 1) { var month = '0'+month; } if(day.toString().length == 1) { var day = '0'+day; } if(hour.toString().length == 1) { var hour = '0'+hour; } if(minute.toString().length == 1) { var minute = '0'+minute; } if(second.toString().length == 1) { var second = '0'+second; } var dateTime = year+'/'+month+'/'+day+' '+hour+':'+minute+':'+second; return dateTime; } 

Answer 4

只要使用：

 var d = new Date(); document.write(d.toLocaleString()); document.write("<br>"); 

Answer 5

 var currentdate = new Date(); var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1) + "/" + currentdate.getFullYear() + " @ " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds(); 

将.getDay()方法更改为.GetDate()并将其添加到月，因为它从0开始计数。

Answer 6

您需要使用getDate（）来获取date部分。 getDay（）函数返回星期数（星期日= 0，星期一= 1 …），而getMonth（）返回一个基于0的索引，所以你需要增加1。

  var currentdate = new Date(); var datetime = "Last Sync: " + currentdate.getDate() + "/"+ (parseInt(currentdate.getMonth()) + 1) + "/" + currentdate.getFullYear() + " @ " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds(); 

Answer 7

getDay()获取星期几。 3是星期三。 你想getDate() ，将返回18 。

另外getMonth()从0开始，你需要添加1得到4 （4月）。

Answer 8

这应该做的伎俩：

 function dateToString(date) { var month = date.getMonth() + 1; var day = date.getDate(); var dateOfString = (("" + day).length < 2 ? "0" : "") + day + "/"; dateOfString += (("" + month).length < 2 ? "0" : "") + month + "/"; dateOfString += date.getFullYear(); return dateOfString; } var currentdate = new Date(); var datetime = "Last Sync: "; datetime += dateToString(currentdate ); datetime += + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds(); 

Answer 9

获取当前的date和时间

 var now = new Date(); var datetime = now.getFullYear()+'/'+(now.getMonth()+1)+'/'+now.getDate(); datetime += ' '+now.getHours()+':'+now.getMinutes()+':'+now.getSeconds(); 

Answer 10

.getDay返回星期几。 你需要.getDate。 .getMonth返回0到11之间的值。您需要将结果加1以获得“人”月份数。

Answer 11

这个小代码很容易，到处都是。

 <p id="dnt"></p> <script> document.getElementById("dnt").innerHTML = Date(); </script> 

有devise的空间

Answer 12

 function getTimeStamp() { var now = new Date(); return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':' + ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now .getSeconds()) : (now.getSeconds()))); } 

Answer 13

 dt= new Date(); alert(dt.toISOString().substring(8,10) + "/" + dt.toISOString().substring(5,7)+ "/" + dt.toISOString().substring(0,4) + " " + dt.toTimeString().substring(0,8)) 

Answer 14

这个问题相当古老，答案也是如此。 我们现在可以使用moment.js来获取当前的date，而不是那些怪异的function，这实际上很容易。 所有必须做的事情是在我们的项目中包含moment.js并且得到一个很好的date，例如：

 moment().format("dddd, MMMM Do YYYY, h:mm:ss a"); 

我认为这使得处理JavaScriptdate更容易。

 function UniqueDateTime(format='',language='en-US'){ //returns a meaningful unique number based on current time, and milliseconds, making it virtually unique //eg : 20170428-115833-547 //allows personal formatting like more usual :YYYYMMDDHHmmSS, or YYYYMMDD_HH:mm:SS var dt = new Date(); var modele="YYYYMMDD-HHmmSS-mss"; if (format!==''){ modele=format; } modele=modele.replace("YYYY",dt.getFullYear()); modele=modele.replace("MM",(dt.getMonth()+1).toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false})); modele=modele.replace("DD",dt.getDate().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false})); modele=modele.replace("HH",dt.getHours().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false})); modele=modele.replace("mm",dt.getMinutes().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false})); modele=modele.replace("SS",dt.getSeconds().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false})); modele=modele.replace("mss",dt.getMilliseconds().toLocaleString(language, {minimumIntegerDigits: 3, useGrouping:false})); return modele; } 

Answer 21

我需要弄明白这个后果的石板。 这是我从几个不同的来源采取元素后想出的 – 格式是MM / DD / YYYY HH：MM AM / PM

 D = new Date(Date(00)); M = D.getMonth()+1; H = D.getHours(); Mi = D.getMinutes(); N = "AM" if (H >= 12) N = "PM" if (H > 12) { H = H-12 } amtOfZeroes = 2; isNeg = false; if (M < 0) { M = Math.abs(M); isNeg = true; } Mo = Math.round(M) + ""; while(Mo.length < amtOfZeroes) { Mo = "0" + Mo; } if (isNeg) Mo = "-" + Mo; if (H < 0) { H = Math.abs(H); isNeg = true; } Ho = Math.round(H) + ""; while(Ho.length < amtOfZeroes) { Ho = "0" + Ho; } if (isNeg) Ho = "-" + Ho; if (Mi < 0) { Mi = Math.abs(Mi); isNeg = true; } Min = Math.round(Mi) + ""; while(Min.length < amtOfZeroes) { Min = "0" + Min; } if (isNeg) Min = "-" + Min; T = Ho + ":" + (Min) Mo + "/" + D.getDate() + "/" + D.getFullYear() + " " + T + " " + N
