在这里看到： http://stackoverflow.com/questions/492994/compare-two-dates-with-javascript [ ^ ]

如果你的日期是字符串，那么你必须使用拆分 [ ^ ]方法。为避免这种麻烦，您应该考虑使用像 https://jqueryui.com/datepicker/ [ ^ ]

接下来，使用适当的日期 [ ^ ]创建日期对象的方法。

尝试这个例子并适应：

< script> 
 var somedayString =16/4/2015; 
 var dateParts = somedayString.split（/）; 
 var day = dateParts [0]; 
 var month = dateParts [1]  -  1; 
 var year = dateParts [2]; 
 //设置日期
某天=新日期（年，月，日）; 
 alert（有一天是+某天）; 
 
 //设置日期
 var today = new Date（）; 
 today.setHours（0,0,0,0）; 
 alert（今天是+今天）; 
 
 if（今天<某一天）{
 text =今天是某天之前。; 
}否则if（今天>某天）{
 text =今天是某天之后。; 
} else {
 text =有一天是今天。; 
} 
 alert（text）; 
< / script> 

请注意，月份数字从0开始，代表1月。

  //  在此处尝试 
  var  currentDate =  new  日期（）
  var  day = currentDate.getDate（）
  var  month = currentDate.getMonth（）+  1  
  var  year = currentDate.getFullYear（）
  document .write(   + day +   / +月+   / +年+    ）
  var  todaysDate = day +   / +月+   / +年

I have a date (ie toDate) in "dd/MM/yyyy" format. Now i want to compare it with today's date in javascript
like

if(toDate>=todaysDate)
{
}

can any one please help me to solve this ?

thanks in advance

解决方案

See here: http://stackoverflow.com/questions/492994/compare-two-dates-with-javascript[^]

If you date is in string, then you have to split them out into the various date parts by using split[^]method. To avoid this hassle, you should consider using a datepicker like https://jqueryui.com/datepicker/[^]
Next, use the appropriate Date[^] methods to create the date objects.
Try this example and adapt:

<script>
var somedayString = "16/4/2015";
var dateParts= somedayString.split("/");
var day = dateParts[0];
var month = dateParts[1] - 1;
var year = dateParts[2];
// set a date
someday = new Date(year, month, day);
alert("someday is " + someday);

// set a date
var today = new Date();
today.setHours(0,0,0,0);
alert("today is " + today);

if (today < someday) {
    text = "Today is before someday.";
} else if (today > someday) {
    text = "Today is after someday.";
} else {
    text = "Someday is today.";
}
alert(text);
</script>

Note that the month numbers start from 0 which represents January.

// try here
 var currentDate = new Date()
 var day = currentDate.getDate()
 var month = currentDate.getMonth() + 1
 var year = currentDate.getFullYear()
 document.write("" + day + "/" + month + "/" + year + "")
 var todaysDate = day + "/" + month + "/" + year
