Question

Toggling an element and its siblings can be accomplished as:

$(this).toggle();
$(this).prev().toggle();

Combining them doesn’t work:

$(this,$(this).prev()).toggle();

How can both be selected at the same time?

Incidentally, while this question has already been answered by drinchev, I thought I’d paste this quick experiment I just did, after reading the question, which also works. Albeit…it surprised me when it did:

$('#recipient').click(
    function(){
        var pair = [this, this.previousElementSibling];
        $(pair).toggleClass('red green');
    });​

Incidentally, a JS Perf loose comparison of the two selector approaches.

Edited to add an IE-(so far as I know)-friendly update, albeit I’m currently saddling all browsers with it, rather than feature-detecting (also, I finally realised that blue != green):

function pESibling(n){
    var nPS = n.previousSibling;
    if (!n || nPS === null){
        return false;
    }
    else if (nPS.nodeType == 1){
        return nPS;
    }
    else {
        return pESibling(nPS);
    }
}

var that = document.getElementById('recipient'),
    pair = [that, pESibling(that)];
$(pair).toggleClass('red green');
console.log(pair);
