New issue 1945 by [email protected]: call SetTime(0,0,0,0) and
throws "this is not a Date object." if Date() object has been subclassed
http://code.google.com/p/v8/issues/detail?id=1945
I am seeing this error being thrown:
Uncaught TypeError: this is not a Date object.
In build:
userAgent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML,
like Gecko) Chrome/17.0.963.46 Safari/535.11
This happens when I am executing this line in Javascript
var theDate = new window.top.Date();
theDate.setHours(0, 0, 0, 0);
I have added a few functions to the date object like this
Date.prototype.MakeisoZDateString = function() {
};
And what I believe is happening in the V8 code is that there is a check
IsDate()
which is checking if the object is explicitly of type Date - however, I
believe by my adding the functions to the Date object, the type is no
longer explicitly Date?
The fix should really be to see if the object is of type Date or has been
derived from Date object.
thanks,
Scott.
