XF 1.5 Make javascript only work on specific dates possible?

Im having some javascripts on my site (snow effect) and it works/gets called by an edit in a template file.
I want it to work on between 20 december and 20 january. is there a way to do this?

 

I want to automate as much as i can

 

Code:

if (Date.now() >= Date(2015, 11, 20) && Date.now() <= Date(2016, 0, 20)) {
  // your javascript here
}

 

Is it possible to remove the year and will it then still work?

 

No.

But you could generalize it by replacing it with Date.prototype.getFullYear()

Code:

var now = Date.now();
if (now >= Date.parse(Date(now.getFullYear(), 11, 20)) && now <= Date.parse(Date(now.getFullYear() + 1, 0, 20))) {
// code
}

 

That will make it work for every year? Thanks!

 

I haven't tested it, but yes, in theory.

 

it doesnt work. i quickly tried to make 20 december into 7 december and the effect is not starting :/

 

I've updated the code, it appears that using Date as a constructor gives a string and not a milliseconds/object. Just checked it out in the console and it works.

 

Really unrelated to this thread, but if you're going to do that snowfalling thing, it may be a good idea to create a custom user field that will let users disable that as it can get fairly annoying if you're trying to read something

 

this is what i have and not working currently.

 

will be difficult....instead im just having the effect small/slightly so its not that intrusive.

 

Not difficult at all, create a custom user field with the id "disableSnowfall" and do this:

Code:

<xen:if is="!{$visitor.customFields.disableSnowfall}">
[Your JS here]
</xen:if>

 

still doesn't tell me everything. what javascript to put there? if i understand correctly this makes it always work or always disabled. I want it only work during my specific time, and then that the user has the option to disable it.

 

Reasons I hate JavaScript...

Code:

var now = new Date();
if (now >= new Date(now.getFullYear(), 11, 20) && now <= new Date(now.getFullYear() + 1, 0, 20)) {
// code
}

 

Jake's point is that you should give the users the ability to disable it. Put the javascript between the conditional statement he provided and people can disable it if they don't want it.

 

currently the script is in a template logo_block. so adding it to the user's field will probaly not work. i think.

 

tried this again, to no success...

 

I attached a picture of the code being run and functioning. What browser are you on?
