How can I make a disjunction of element selectors with jQuery?

What I need is something like this:

$('element1 or element2').mouseover(function()
{
   $('element3').show(e开发者_JS百科ffects,blah);
});

I hope I just overlooked this possibility in the jQuery docs.

Just use a comma to separate the selectors:

$('element1, element2').mouseover(function()
{
   $('element3').show(effects,blah);
});

The comma is the CSS syntax for selector grouping.

You can do it with a comma in the selector, or you can use add.

$('element1, element2').mouseover(...);
$('element1').add('element2').mouseover(...);

Sure, just as you can specify it in CSS, just use a comma-separated list:

$('.element1, .element2').mouseover(function() { 
    $('element3').show(effects,blah); 
});
