Safari: using dojo.event.connect to cause form submit does not work

[anonymous]

In Safari, using dojo.event.connect to fire a form's submit method does not work. It does work in Firefox, though.

var myform = dojo.byId('myForm');
var mybutton = dojo.byId('myButton');
dojo.event.connect(mybutton,'onclick',myform,'submit');

// doesn't work in safari... however the following DOES work in Safari:

var myform = dojo.byId('myForm');
var mybutton = dojo.byId('myButton');
dojo.event.connect(mybutton,'onclick',submitmyform);

function submitmyform() {
   myform.submit();
}
