Use event arguments with other arguments?

Question

Here's what I want to do:

function someEvent(e) {
}

onxxxx="someEvent()"

and turn that into:

function someEvent(e, arg1, arg2) {
}

onxxxx="someEvent(???)"

So basically, I want to pass other arguments including the default event one, but I'm not sure quite how to

@WillP. In essence yes, but no because I need to use the HTML attribute for the event, not addEventListener — Oztaco, Feb 21 '14 at 23:07
@htatche So that I don't need to write one function for many slightly different pieces of code — Oztaco, Feb 21 '14 at 23:07
You could have function1, function2, function3, functionX, each one calling `someEvent()` with a different set of arguments, and then call one of those functions from onxxx. But I still don't see a real need for it... — htatche, Feb 21 '14 at 23:10

You can pass the event object as an argument:

onxxxx="someEvent(event, arg1, arg2);"

event must be literal event here.

Within the eventhandler function you find them like so:

function someEvent(e, a, b) {
    // e === event object
    // a === arg1
    // b === arg2
}

You could use anonymous functions:

var arg1 = "12345 - test", arg2 = 42;

onxxxxx = function(e) {
    someEvent.call(this, e, arg1, arg2);
};

Thank you for your answer, but I need to know how to do it straight from HTML attributes, Teemu's answer works – Oztaco Feb 21 '14 at 23:20
@leaf68 OK. I didn't understand that was what you wanted. – Toothbrush Feb 21 '14 at 23:54
