calculate age

Recommended Posts

You can insert the following in the Footer to calculated the age, and assign the value to the "Age" field after submitting:

function ageCalculate()
//get current date
var stamp = new Date(); 

//get Birthday. change "InsertRecordBirthday" if the fieldname is different
var insertDate = document.getElementById('InsertRecordBirthday').value;
var birth = new Date(insertDate);

difference = stamp - birth;
age = Math.floor(difference / (1000 * 60 * 60 * 24 * 365.25));

//assign it to Age field 
document.getElementById('InsertRecordAge').value = age;

The Calculated Value form element generates dynamic calculations that automatically update as users interact with your form is now available in the current platform of Caspio. You can calculate the age of a person automatically without submitting the form and without custom programming.

You can construct the calculation using functions, logic, constants, values from other fields and SQL expressions.
