I want to perform a validation for today's date and user entered date in my custom list form's multiple datetime fields

  • ReqstRecvdDate Field
  • DueByDate field
  • ReqstRecvdDate can not be greater than today's date.It can be equal to today's date or less than today's date.
  • if RecvdDate>=Today , I need to prevent user from saving the form- presaveaction call.

    Also DueByDate field, which has to be greater than ReqstRecvdDate Field. I added the below code, but the validation is not working when

    a) I selected 31-Oct-2015 as ReqstRecvdDate & I selected DueByDate field as 01-Dec-2015. As per the rule it's set to true and should allow me to save the form, but this didn't happen.

           <script language="javascript" 
           src="/project/EASAssetsLib/jquery-1.6.0.min.js" 
           type="text/javascript"></script><script language="javascript" 
             src="/project/EASAssetsLib/jquery.SPServices-
            2014.01.min.js" type="text/javascript"></script><script 
         language="javascript" 
            src="/project/EASAssetsLib/prototype.js" 
           type="text/javascript"></script><script language="javascript" 
           src="/project/EASAssetsLib/SPUtility.js" 
           type="text/javascript"></script><script language="javascript" 
            type="text/javascript">
    
         function PreSaveAction()
          {
           var reqstrecvddatethrusputility = SPUtility.GetSPField('Request 
           Received Date').GetValue(); 
          var reqsteDateStr=reqstrecvddatethrusputility.toString();
          var mon1  = reqsteDateStr.substring(0,2); 
           var dt1 = reqsteDateStr.substring(3,5); 
           var yr1  = reqsteDateStr.substring(6,10);  
           temp1 = mon1 + "/" + dt1 + "/" + yr1;
           var dtReqstRecvdDate = new Date(temp1);
           var reqstRecvdDateInUTC = dtReqstRecvdDate.toUTCString();
            var currentTime = new Date();
           var CurDateInUTC = currentTime.toUTCString();
          dt3 = new Date(reqstRecvdDateInUTC);
          dt4 = new Date(CurDateInUTC);
       if(dt3 > dt4 )
         {
           alert('Received Date cannot be greater than Todays  
                   Date!');
           return false;
         } 
    

    Due to some reason,month range is not getting recognized properly.

    What I need to change in my code to do the right validation?

    Doing String operations on Dates is never a good habit.

    You are adding so many libraries allready.
    Adding momentJS to make date calculations a breeze won't be an issue..

    Your Month problem is probably because in JavaScript january === 0 , thus december === 11

    • I downloaded the moment.js into my assets lib.How to use it with dates which is coming from SharePoint datefield? – userAZLogicApps Nov 2 '15 at 10:12
    • I got the date format value like this: var reqstrecvddate2 = SPUtility.GetSPField('Request Received Date').GetValue(); var duebydate2 = SPUtility.GetSPField('Due By').GetValue(); var reqstrecvddate2moment = moment(reqstrecvddate2).format("MM/DD/YYYY"); alert(reqstrecvddate2moment + ' ...from moment' ); But how to compare the reqstrecvddate2 against duebydate2moment ? – userAZLogicApps Nov 2 '15 at 10:19
    • You are taking too many steps at once. First play with/learn JavaScript date calculations, then make it work in SharePoint. Your problem is not SharePoint. Your problem is you do not understand working with JavaScript dates. – Danny '365CSI' Engelman Nov 2 '15 at 10:25
    • Agreed!.Let me work on that and revert. – userAZLogicApps Nov 2 '15 at 10:43
