Plupload Forum → General discussion → Confusing way to use events
Got this from http://www.plupload.com/punbb/viewtopic.php?id=1653.
Use postinit event:
preinit: {
PostInit: function(up) {
//your code here
}
}
This code works, so I assume it's correct, but I find it very confusing – PostInit is inside preinit. Can anyone explain the rationale behind this?
the preinit is a section and the postinit is an event.
all events inside the "preinit" section will be executed before the event defined by plupload. In this case the "postInit" event is already defined inside the runtimes html5, gears and browserplus. So if your postinit event must run before the defined plupload code, you should put it inside the preinit section
Thanks for the explanation, Leandro. But what is a "section" here? Is it a JavaScript concept or something plupload devs have come up with?
It would be good if somebody wrote a set of documentation articles explaining things like that.
the term "section" is something that I came up with to explain this for you.
the http://www.plupload.com/documentation.php already have an explanation about the "preinit"
I saw it. Firstly, that article is too deficient in details. Secondly, here's what it says:
preinit
Function callback that enables you to bind events before the uploader is initialized.
I wanted, for example, to change text in the queue widget, so doing that "before the uploader is initialized" didn't make sense, yet this is exactly where it worked.
Still, this area is confusing. Good docs would help, but they don't exist. People have been inquiring about basic things that should've been covered by documentation.
Now I feel I might be interpreted as an ungrateful SOB. I am not. I am thankful for this software and that it's free. Good docs would help, though 
you didn't read it right. let me change the bold font position
preinit
Function callback that enables you to bind events before the uploader is initialized.
so you're not executing code on preinit, but only binding the events to plupload before the native events are bound
and thinking a little more deeply, why someone will define a section that executes any code before the plupload is initialized? if we need this, we just put our code before calling the plupload initialization code. Right?
That makes more sense now. Thanks.

Sounds right, but I want to know if I got you correctly. For example, I needed to change the header text and remove a button from the queue widget, so I did the following:
preinit: {
PostInit: function(up) {
$(".plupload_header_text").html("Add files to the upload queue and click the Save button.");
$(".plupload_start").hide();
}
}Can you think of another way that would work and make more sense?
the only way to define events handlers are:
- in preinit
- in init
- and with the bind method
Do you mean to define events or to define event handlers?
