How to call event as a function in mozilla

[Jadow]

I have a function that is used as an event for some parts of the
script.
i.e.
function somethind(e) {
if (!e.currentTarget.documentElement ){
...
}
}

I need to call this function manually (not by assigning it to an
event) Yet I cannot seem to deal with 'e'.
If I call it as: something(e); I get a 'not defined', if I ommit it I
get an undefined.
For some reason 'e' is undefined in the calling script. What decides
when it is available as an event object? and how can I resolve this
issue?

Thanks

I have a function that is used as an event for some parts of the
script.

It is an event handler. The "e" will be the event then.

function somethind(e) {
if (!e.currentTarget.documentElement ){
...
}
}

That requires the currentTarget property to be a document object.

event) Yet I cannot seem to deal with 'e'.
If I call it as: something(e); I get a 'not defined', if I ommit it I
get an undefined.

If you write
something(e);
and "e" is not a defined variable, then it is ofcourse an error. You have
to add an event as argument (or any object with a currentTarget property).
Try
something({currentTarget:document});

For some reason 'e' is undefined in the calling script.

That reason is proabably that it hasn't been defined.

What decides when it is available as an event object?

When you assign it. The "e" in the function definition only
exists inside the function. It is a local name for the argument
to the function.
