fluent form age calculate

       // Age calculator



	// 1. First take a Date picker & a text input field 
	// 2. In the text input element add the class 'age'
	// 3. Add a custom class 'date' in the date picker ,then add the following js in your fluent form custom js
	

	jQuery( ".date" ).change(function() {
	    
	    var age = getAge(jQuery(this).val())
	    jQuery('.age').val( age)

	});
	

	function getAge(DOB) {
	    
	    //when date format dd/mm/yyyy
	    birthDate = DOB.split("/");
        currentDate = new Date();
        
        // javascript month counts from 0, so add +1        
        var years = (currentDate.getFullYear() - birthDate[2]);
      
        if (currentDate.getMonth()+1 < parseInt(birthDate[1]) || currentDate.getMonth()+1 == parseInt(birthDate[1]) && currentDate.getDate() < birthDate[0]) {
            years--;
        }
        if(years < 0){
            years = 0;
        }
	    return years;
	}

and also, var age = getAge(jQuery(this).val()) it's showing semi column missing at this line

You may want to check line 21 whether you split by the right character, depending on the date format chosen. I had dots, so I had to adjust it to birthDate = DOB.split(".");
