Date.now() not working in template


I want to use the Date.now() functionality in the template to compare a date with the current date, but it looks like the date object is always null, and when I use Date.now() the template renders as #TemplateName (as in an error raised probably?)

<##script type="text/x-jsrender" id="Status">
    ${if(DateFinished == null)}
    <##span>DateFinished is null!
    ${else if(Date == null)}                   <!--CONDITION IS ALWAYS TRUE!-->                
    <##span>Date is null!
   ${else if(DateFinished != null  && Date.now() > DateFinished)}    <!--THIS LINE BREAKS THE TEMPLATE, AND THE RESULT IS ALWAYS #Status-->
    <##span>Date is null!
    <##span>in last else statement

P.s. How can I add code fragments into a forum post (with markup, and without have to use the <## I do above

Hi Thijs 
Greetings from Syncfusion support. 
Your requirement for using Date.now can be achieved by using the Custom Helpers in the template. Please find the sample custom helper and template in below code  
Custom helper:  
window.processData = function(value){  
    if(value >=  5){  
        return '<span >Higher value</span>'  
    } else {  
        return  '  <span >'+ Date.now()+'</span>'  
<script id="template" type="text/x-jsrender" >  
In the above example custom helper window.processData  we can process the data processing within the helper function and return the desired result to the template output and in the template section we can call the custom helper as in the above snippet and pass the desired arguments with data prefix (data.EmployeeID) to the helper for process and get desired output.  
Please get back to us, if you need any further assistance.

Hello Mydeen,

Thx, this works!

The data prefix does not work (anymore) for me, I can only use the properties directly? is there something I can do to make the data prefix work? and is there a possibility that I can pass the entire data object as a parameter to the function?

Or use multiple parameters in the helper function like:

${getStatusFlag(StartDate, FinishedDate)}

window.getStatusFlag = function (date1, date2) {
     //do actions

in this example both dates are concatenated in the first parameter (date1) of the function

Kind regards,
