restrict form from submission

[Harpreet]

Hello ,

I am using a javascript that should restrict me from submitting form based on condition.

I have field Start date and field End Date.

Then I am using a virtual calculated field to find number of days from the above two fields. Now if my value is greater than 5 it should restrict me to submit the form

 

 

<script>
  document.addEventListener('BeforeFormSubmit', function(event) {

     let checkValue = document.getElementById("cbParamVirtual3").value;
    
     if (checkValue > 5) {
     event.preventDefault();
     alert("You are not authorized to create this account.");
    }
  });
</script>

 

Ca anybody please help

Hi @Harpreet! Just to add, your condition is already correct, but there is a mistake in the declaration on your field.

You may use this instead:  let checkValue = document.getElementsByName("cbParamVirtual3")[0].value;
