javascript error { [native code] }

Question

Hi I'm trying to do some basic javascript and am getting "native code" instead of what I want:

<script type="text/javascript">
var today = new Date();
document.write(today + "<br />");
//document.write(today.length + "<br />"); - was getting "undefined"
//document.write(today[0] + "<br />"); - was getting "undefined"
document.write(today.getMonth + "<br />");
document.write(today.getMonth + "<br />");
document.write(today.getFullYear + "<br />");
</script> 

output was:

Fri Jan 13 14:13:01 EST 2012
function getMonth() { [native code] } 
function getDay() { [native code] } 
function getFullYear() { [native code] } 

what I want is to get the current Month, Day, Year and put it into an array variable that I will be able to call later on. I'm not getting far because of this native code. Can someone tell me what it is and hopefully, more importantly I can complete this project? Thank you for your time and help, it is much appreciated!

Answer 1

The getMonth and the rest are functions, not properties, when you call just today.getMonth you are getting a reference to the actual function. But, if you execute it using parenthesis, you get the actual result.

Your code should be:

document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

Answer 2

You are missing the parenthesis().

document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

Answer 3

document.write(today.getMonth() + "<br />"); // notice the ()'s to invoke the function
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

Answer 4

getMonth and getFullYear are functions, so you need to invoke them. Note the parentheses:

document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

As you have it, it's printing the string representations of the functions, not the functions' values.
