javascript Date().getTime() is not a function

问题:

I'm trying to compare some Dates in javascript.

For some reason, I'm getting "Tue May 01 2012 16:43:03 GMT+0900 (JST) has no method 'getTime'"

Of course, strings don't have methods

I started with this code inside a callback, but it was failing at getTime() on the line that creates var age:

for (var i = 0; i 

I've pared it down so my example page is literally just this:

This is failing in Chrome 18.0.1025.168 and Firefox 13.0.

Screenshots of what I've tried:

So my question:

wth?

Do I have to use ParseDate()? Why isn't this working?

回答1:

Try using new keyword to instantiate a new object so instead of this

var now = Date(); 

try this

var now = new Date(); 

回答2:

You need to use the new operator to create a Date object.

(new Date()).getTime() 

回答3:

This will make 'now' as variable type as date:

var now = new Date(); 

This will get you time from 'now':

new Date(now).getTime();
