Why javascript getTime() is not a function?

Question

I used the following function,

function datediff()
{
 var dat1 = document.getElementById(\'date1\').value;
 alert(dat1);//i get 2010-04-01
var dat2 = documen         


        

Answer 1

To use this function/method,you need an instance of the class Date .

This method is always used in conjunction with a Date object.

See the code below :

var d = new Date();
d.getTime();
