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

dat1 and dat2 are Strings in JavaScript. There is no getTime function on the String prototype. I believe you want the Date.parse() function: http://www.w3schools.com/jsref/jsref_parse.asp

You would use it like this:

var date = Date.parse(dat1);
