Question

Age calculation that if >6 months show 1 year value

Hello!

I am looking for a help to understand why the below script does not work the way I would like it to work.

I would like the script to give me below value:

- if age < 1 and month <6  then give me months count with word "month(s)" 

- if age <1 and month >=6, then give me a value of "1 year".

The below code seems to work fine, but does not give a word "month(s)" in the first condition.

Could some help me adjust the code so that it would work?

 

event.value = "";

var dobValue = getField("Textfield-54").value;

if (dobValue!="") {

var dob = util.scand("mm/dd/yyyy", dobValue);

var today = new Date();

var age = today.getTime() - dob.getTime();

// compute age in milliseconds

var nAgeMilliseconds = today.getTime() - dob.getTime();

var nAgeYears = ( age / (1000 * 60 * 60 * 24 * 365.2425) - 0.005);

if(nAgeYears < 1) {

var nAgeMonths = today.getMonth() - dob.getMonth();
if(nAgeMonths < 6)

nAgeMonths += 12;

event.value = Math.floor(nAgeMonths) + " Months";

if(nAgeMonths >= 6)

nAgeMonths = 1;
event.value = Math.floor(nAgeMonths);
}
else

event.value = Math.floor(nAgeYears);

}

You have to add curly brackets to attach more than one line of code to an if-statement.

Try this:

 

if(nAgeYears < 1) {
	var nAgeMonths = today.getMonth() - dob.getMonth();
	if (nAgeMonths < 6)	{
		nAgeMonths += 12;
		event.value = Math.floor(nAgeMonths) + " Months";
	} else if (nAgeMonths >= 6) {
		nAgeMonths = 1;
		event.value = Math.floor(nAgeMonths) + " Months";
	}
} else {
	event.value = Math.floor(nAgeYears) + " Years";
}

 

Note I didn't check the logic of your code, just fixed the syntax and added the missing strings.

Thank you try67, for the fixed syntax, however, it doesn't give me 1 year when there are 6 or more months instead it gives me # of months.

Change this:

 

} else if (nAgeMonths >= 6) {
nAgeMonths = 1;
event.value = Math.floor(nAgeMonths) + " Months";
}

 

To:

 

} else if (nAgeMonths >= 6) {
event.value = "1 Year";
}
