出發和返回的日期

Question

function CompareDate(epr_departuredate,epr_returneddate) { 
    var epr_departuredate = new Date(24,11,2016); //Today Date 
    var epr_returneddate = new Date(25,11,2016); 
    if (epr_departuredate >epr_returneddate) { 

     alert("Departure Date Cannot Late Than Return Date. Please Check"); 
    }else { 
     alert("Date You Enter is Valid. Please Continue."); 
    } 
} 

爲什麼我的代碼不工作，只顯示：

出發日期不能遲到總比不到返程日期。請檢查。

當我跑步。我只想比較出發日期和返回日期。

Answer 1

您可以檢查此：

function CompareDate(epr_departuredate,epr_returneddate) { 
    epr_departuredate="2017/05/28";//say it is string and pass this value when call the function 
    epr_returneddate="2017/05/29" 
    var departuredate = new Date(epr_departuredate); //Today Date 
    var returneddate = new Date(epr_returneddate); 
    if (departuredate >returneddate) { 

     alert("Departure Date Cannot Late Than Return Date. Please Check"); 
    }else { 
     alert("Date You Enter is Valid. Please Continue."); 
    } 
}
