Question

I have a form input with an id of date_trans . The format for that date input (which is validated server side) can be any of:

dd/mm/yyyy
dd-mm-yyyy
yyyy-mm-dd
yyyy/mm/dd

然而,在张贴表格之前,我要检查“过渡领域”的日期是否与今天的日期相同。如果所收日期是客户日期(即使用js),因为我也对服务器进行了双重检查。

I m totally lost on how to do the date comparrison in jQuery or just plain old javascript. If it helps, I am using the jquery datepicker

Answer 1

对纯联合材料进行简单日期比较应当足够:

// Create date from input value
var inputDate = new Date("11/21/2011");

// Get today s date
var todaysDate = new Date();

// call setHours to take the time out of the comparison
if(inputDate.setHours(0,0,0,0) == todaysDate.setHours(0,0,0,0)) {
    // Date equals today s date
}

Answer 2

for completeness, taken from this solution:

你们可以利用:

var today = new Date();
var isToday = (today.toDateString() == otherDate.toDateString());

没有图书馆的附属设施,也没有比以前的答复中显示的“众人”做法更清洁。

Answer 3

使用时间。 j)

moment( dd/mm/yyyy ).isSame(Date.now(),  day );

You can replace day string with year, month, minute if you want.

Answer 4

function sameDay( d1, d2 ){
  return d1.getUTCFullYear() == d2.getUTCFullYear() &&
         d1.getUTCMonth() == d2.getUTCMonth() &&
         d1.getUTCDate() == d2.getUTCDate();
}

if (sameDay( new Date(userString), new Date)){
  // ...
}

利用UTC*方法,确保不同时区与同一全球日相匹配的两天时间相同。 (如果你重新规定这两个日期,则没有必要,但需要考虑的是一件好事)。

Answer 5

Just use the following code in your javaScript:

if(new Date(hireDate).getTime() > new Date().getTime())
{
//Date greater than today s date 
}

根据你的要求改变条件。 http://www.w3schools.com/js/js_comparisons.asp” rel=“noreferer” 相比之下,java script

Answer 6

以下解决办法比较了按小时、分钟、秒、米、磨粉等值分列的时间整数。

var reducedToDay = function(date){return ~~(date.getTime()/(1000*60*60*24));};
return reducedToDay(date1) == reducedToDay(date2)

The tilde truncs the Division results (see this article about integer Division )

Answer 7

Try this

// method to check date is less than today date
  isLessDate(schedule_date : any){
    var _schedule_date = new Date(schedule_date);
    var date = new Date();
    var transformDate = this.datePipe.transform(date,  yyyy-MM-dd );
    var _today_date = new Date(  +transformDate);
    if(_schedule_date < _today_date){
      return  small 
    }
    else if(_schedule_date > _today_date){
      return  big 
    }
    else {
      return  same 
    }
  }

Answer 8

Date.js是一个手提图书馆,用于操纵和编排日期。它可以在这种情况下提供帮助。

Answer 9

比较日期的最佳方式和建议方式是:

var today = new Date().getTime();
var reqDateVar = new Date(somedate).getTime();

if(today === reqDateVar){
 // NOW
} else {
 // Some other time
}
