Function always return same value instead throw else clauseif condition is not valid

Question

I have this query running from JSLink into list. It get current time from moment.js and compare date with sharepoint column ctx.CurrentItem.Cumplimiento; and return result into column sCumplimientoInicial

 function overrideCumplimiento(ctx) {
         var sIconFileName = "";


    var currentServerDateTime = moment().format("DD/MM/YYYY"); 
    var sCumplimiento = ctx.CurrentItem.Cumplimiento;
    var sCumplimientoInicial = ctx.CurrentItem.Fecha_x0020_Compromiso_x0020_Ini;


      if(currentServerDateTime < sCumplimientoInicial){
       sCumplimiento  = 'Yes'
      }else{
       sCumplimiento  = 'No'
      }
    return sCumplimiento;
   }

Problem is when currentServerTime is bigger than sCumplimientoInicial it return "Yes" instead "No", and it always return Yes. Any idea what is wrong there?

I think it is because sCumplimiento is an string and no date. Because if I select first, second of any month it return no so it is not comparing from dates just from string. How can I achieve this comparation of dates correctly?

UPDATE: As comments below I try to do it using

 var sCumplimientoInicial = moment("ctx.CurrentItem.Fecha_x0020_Compromiso_x0020_Ini");

But I getting "Invalid Date"

Answer 1

To cast a string field to date try this

var FDate = new Date(your field with DateTime Data Type);

Ex: var FDate = new Date(ctx.CurrentItem.Fecha_x0020_Compromiso_x0020_Ini);

Note: in case your field is string, try to parse your code with moment

var momentDate = moment("your field");

In case it's not working, try to customize your string in the correct date format "MM/dd/yyyy" then parse the output to date as the following

var day  = str.substring(0,2);
var mon = str.substring(3,5);
var yr  = str.substring(6,10);  
var dateformated = mon + "/" + day + "/" + yr;
var sCumplimientoInicial = Date.parse(dateformated);

---

To compare with today try this

 var today = new Date();

So the condition should look like

if(today < FDate )

{
       sCumplimiento  = 'Yes'

}
else
{
       sCumplimiento  = 'No'
}

You do not have to do the calculations;

SharePoints adds a 'GetDaysAfterToday' function

see: Change the color of a row when Date >= today's date
