jQuery具有窗口或文档的多个选择器

Question

I know how to use multiple CSS selectors with jQuery, but how can I bind an event listener to multiple selectors when one of them is an object, the document or the window object for instance.

The following doesn't work :

$('html, body', document).scroll(function () {
    if(Screen.detectScroll() === 'down') {
        self.hide();
    } else {
        self.show();
    }
});

You can use jQuery's Add() to add selectors.

$('html, body').add(document).scroll(function () {
    if(Screen.detectScroll() === 'down') {
        self.hide();
    } else {
        self.show();
    }
});
