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 < array_of_usage_indices.length; i++) { store.get(array_of_usage_indices[i]['key'],function(may_need_gc) { if(may_need_gc) { var now = Date(); var created = Date(may_need_gc['value']); var age = now.getTime()-created.getTime(); } }) } I've pared it down so my example page is literally just this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>date test</title> </head> <body> <script type="text/javascript" charset="utf-8"> var now = Date(); alert(now.getTime()); var t = Date().getTime(); </script> </body> </html> This is failing in Chrome 18.0.1025.168 and Firefox 13.0.

So my question:
wth?
Do I have to use ParseDate()? Why isn't this working?

Javascript date getTime() method returns the numeric value corresponding to the time for the specified date according to universal time. The value returned by the getTime method is the number of milliseconds since 1 January 1970 00:00:00. You can use this method to help assign a date and time to another Date object.
Use the getTime() method to get a UTC timestamp, e.g. new Date(). getTime() . The method returns the number of milliseconds since the Unix Epoch and always uses UTC for time representation. Calling the method from any time zone returns the same UTC timestamp.
JavaScript Date getTime() getTime() returns the number of milliseconds since January 1, 1970 00:00:00.
Try using new keyword to instantiate a new object so instead of this
var now = Date(); try this
var now = new Date(); You need to use the new operator to create a Date object.
(new Date()).getTime() If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
