JQuery adding variables

Question

I used the following code to add three variables, but instead of adding these variables, it combines these variables.

var registration_fee = $('input[type="radio"][name="registration_fee"]:checked').val(); var material_fee = $('input[type="radio"][name="material_fee"]:checked').val(); var tuition_fee = $('input[type="radio"][name="tuition_fee"]:checked').val(); // alert(tuition_fee) var total_fee = registration_fee + material_fee + tuition_fee; $('#total_fee').html(total_fee); 

Answer 1

Pass them to numbers using parseInt or parseFloat :

 var total_fee = parseInt(registration_fee) + parseInt(material_fee) + parseInt(tuition_fee); 

Answer 2

Try:

 var total_fee = parseInt(registration_fee, 10) + parseInt(material_fee, 10) + parseInt(tuition_fee, 10);
var total_fee = parseInt(registration_fee, 10) + parseInt(material_fee, 10) + parseInt(tuition_fee, 10); 

Or parseFloat, whichever suits

Answer 3

Try

Pass them to numbers using Number

tal_fee = Number (registration_fee) + Number (material_fee) + Number (tuition_fee);

Answer 4

Use parseInt to convert a string to int or parseFloat for float.

Answer 5

Try using parseInt(price) + parseInt(ticket_buyer_fee) for the variables that it uses.
