如何使用javascript比较两个日期时间与时区偏移（比较大于或小于）

Question

So I have a scenario where I need to compare Date1 and Date2
where Date1 = 05.01.2008 6:00 +5:00
and Date2 = 05.01.2008 7:00 +5:00
I am not getting a way to convert these datetimeoffsets to a particular conversion format. Plz help.
Here is what all i have tried till now

function validate()
    {
        var a = document.getElementById("txtDate1").innerHTML;
        var b = document.getElementById("txtDate2").innerHTML;
        if (a > b) {
            alert('greater')
        }
        else {
            alert('Smaller')
        }
    }

Answer 1

use below code. using Date.parse

 var date1 = new Date(Date.parse("05.01.2008 6:00 +5:00")); var date2 = new Date(Date.parse("05.01.2008 7:00 +5:00")); if (date1 < date2) { alert('Smaller') } else if (date1 > date2) { alert('greater') } else { alert("date1 === date2"); }

You would first need to parse them as Date objects for comparison. One popular option is using moment.js , since it can interpret many formats. Then you can compare them by using Date.prototype.getTime function to get the Unix timestamp, which all use the same time zone.

The way you compare them at the moment is as String types, which will not work.
