If you need to reference your function in the function body, it's obvious you should be using a named function, not an anonymous one. Specifying a name will create a local variable in the functions scope of that name. Use that instead. Don’t use arguments.callee, it’s deprecated!

function Y(le) {
return (function (f) {
return f(f);
}(function (f) {
return le(function (x) {
return f(f)(x);
});
}));
}

myButton.onclick = Y(function(f) {
if(i==0)
{
alert(”DONE”);
myButton.value = i;
return i;
}
alert(i);
return f(–i);
});
