jQuery select 'this' and another selector at same time

I am using a jQuery click function and would like to know if I can use the term 'this' to select the nav element and another selector at the same here's my code:

$('#nav').click(function() {
    开发者_如何学编程$(this, '#anotherSelector').hide();
});

This doesn't work. It selects the #anotherSelector and not the #nav element as well. What am I doing wrong?

Many thanks in advance.

Use .add() to add another selector into your set of elements you want to deal with, like this:

$('#nav').click(function() {
    $(this).add('#anotherSelector').hide();
});

---

Use $(this).add('#anotherSelector').hide(); instead.

See add

What you've got at the moment reads as "search for the DOM element (this), that is inside the element whose ID is anotherSelector."; see here for more info.

You can use the add() function to extend your selection

$(this).add('#anotherSelector').hide();

---

$('#nav').click(function() {
    $('#nav, #anotherSelector').hide();
});
