Hi Guys,
I have some javascript that calculates a persons age in yeats, months and days from their of dob to the time of admission.
So a user enters a DOB and a date of admission.
The age at admission is then auto calculated.
It work well, however I'm getting some inconsistent values with only the days calculatein of the formula where it seems to add extra days to the day portion only.
For example a person born 01/01/2005 and Admitted 23/08/2020 age calculation reads 15 years 7 months 26 days when the correct value should be 15 years, 7 months, 23 days (including the end date)
Any ideas how to tweak the days portion of JS below?
/// Age from db
var ctrldob = Runner.getControl(pageid, 'dob');
var ctrldoa = Runner.getControl(pageid, 'cc_Start_Date');
var ctrlpatient_age = Runner.getControl(pageid, 'patient_age');
ctrldoa.on('blur', setDateParams);
ctrldob.on('blur', setDateParams);
function setDateParams() {
if(ctrldob.getValue())
{
$('#p_dob').html($('#tsvalue_dob_1').val());
}
if(ctrldoa.getValue() && ctrldob.getValue())
{
var user_date = Date.parse(ctrldob.getValue());
var today_date = Date.parse(ctrldoa.getValue());
var diff_date = today_date -user_date ;
var num_years = diff_date/31536000000;
var num_months = (diff_date % 31536000000)/2628000000;
var num_days = ((diff_date % 31536000000) % 2628000000)/86400000;
var agestr = Math.floor(num_years) + ' Years ' + Math.floor(num_months) + ' Months ' + Math.floor(num_days+1) + ' Days';
ctrlpatient_age.setValue(agestr)
$('#p_age').html(agestr);
}
}
Thanks J
