您需要存储每个手风琴的旗帜状态。一个简单的方法是使用 jQuery data()...

$('.togglebutton').data("flag",1);
$('.togglebutton').click(function() {
    var $t = $(this);
    if ($t.data("flag") == 1) {
        $t.find('img')[0].src = "//placehold.it/40/?text=M";
        $t.data("flag",0);
    } else {
        $t.find('img')[0].src = "//placehold.it/40/?text=P";
        $t.data("flag",1);
    }
})
