如何使此切换淡入淡出适用于每个items
块?当我点击任何人时,它会应用所有这些。有人可以帮忙吗?谢谢
<div class="items">
<div class="warp">
<span class="change">Tester</span>
<span class="click">expand</span>
</div>
<div class="invisible">
<div class="red"> red </div>
<div class="black"> black </div>
</div>
</div>
<div class="items">
<div class="warp">
<span class="change">Tester</span>
<span class="click">expand</span>
</div>
<div class="invisible">
<div class="red"> red </div>
<div class="black"> black </div>
</div>
</div>
jQuery
$('.invisible').hide();
$('.warp').addClass('bg');
$(".warp").click(function () {
$(".invisible").slideToggle("slow", function () {
if ($(this).is(':visible')) {
$('.warp').removeClass('bg');
}else{
$('span.click').css('visibility', 'visible');
$('.warp').addClass('bg');
}
});
$('span.click').css('visibility', 'hidden');
});
