jquery
复制代码 代码如下:
$(document).ready(function(){
var h3=$(".accordion h3");
$(".accordion h3:eq(0)").addClass("active");//1.首先获取第一个H3标签添加class；
$(".accordion p:gt(0)").hide();//在获取除了第一个p标签以外的所有标签都隐藏；
h3.click(function(){
$(this).next("p").slideToggle("slow")//查找下一个p标签添加动画，并查找它的兄弟节点是否显示，如果显示就隐藏
.siblings("p:visible").fadeOut("slow");
$(this).toggleClass("active");//给H3标签添加class（如果有就不添加 没有就添加），查找兄弟节点移除class
$(this).siblings("h3").removeClass("active");
});
});
