Why isn't this script working???

<script type="text/javascript">
function getAgeYears() {
"use strict";
var dobYear = 1987,
dobMonth = 1,
dobDay = 22,
now = new Date(),
nowYear = now.getFullYear(),
nowMonth = now.getMonth() + 1,
nowDay = now.getDate(),
yrAge = nowYear - dobYear;
if (nowMonth < dobMonth) {yrAge--; } else if (nowMonth === dobMonth && nowDay < dobDay) {yrAge--;
return yrAge; }
document.write(getAgeYears());
}

Code (markup):

I will admit that I'm a novice coder, but I can't get this to work for the life of me. Any help is appreciated.

 

here's what i found about your code, seems to be a logical error.

on line 15
document.write(getAgeYears());

this will make your function a 'recursive function' . you are calling this inside your function. remove it and place it outside the function.

 <script type="text/javascript">
            function getAgeYears() {

                var dobYear = 1987,
                dobMonth = 1,
                dobDay = 22,
                now = new Date(),
                nowYear = now.getFullYear(),
                nowMonth = now.getMonth() + 1,
                nowDay = now.getDate(),
                yrAge = nowYear - dobYear;
                if (nowMonth < dobMonth) {yrAge--; }
                else if (nowMonth === dobMonth && nowDay < dobDay)
                {
                    yrAge--;                   
                }
               
                return yrAge;
               
            }
         
            document.write(getAgeYears());
        </script>

Yes, I have tried that. I still get no output from the script.

 

have you tried my code? as i tested it and it display age . please copy my code and run it.

another bug in your code is statement of 'return' in else{} body. it should be at the end of function
