How to change onClick with JavaScript, including function parameter(s)

Question

In JavaScript I can assign onclick by traditional way:

button.onclick = engineStop();

But how can I assign to onclick a function with parameter(s)?

This does not work >>

button.onclick = engineStop(this);

The function needs to receive this parameter to know which button has been clicked on.

Please advice... (no jQuery)

button.onclick = function() {engineStop(this);};

Using an anonymous function.

Like this:

function engineStop(param){
    return function(){
        //engineStop function's body here,
        //which uses 'param' argument
    };
}
button.onclick = engineStop(this);
