具有多个div的每个函数jquery

Question

我有几个div和一个类“..intro”。在这些div中，我有按钮标记来触发类“..more”的div的上下滑动。如何对其进行编码，使其打开相关的“更多”div，而不是同时打开所有这些？

这是我到目前为止尝试过的jquery：

function answer() {
   $(".trigger").click(function () {
        if ($(".slider").hasClass("slideup"))
            $(".slider").removeClass("slideup").addClass("slidedown");
         else
            $(".slider").removeClass("slidedown").addClass("slideup");
        });
   }; 



$.each($(answer($('.intro'))));

我的HTML在这里：

 <div class="container">
      <div class="icon">
        <img src="images/tour-1.png" alt=""/>
    </div>
    <div class="intro">

$('.trigger').click(function () {
    $(this).siblings('.slider').find('.more').slideToggle();
});

Answer 2

如果我理解了，您希望在div '.intro‘内滑动类’.intro‘的div，并触发按钮。

$(".trigger").click(function () {
    var slider = $(this).parent().find('.slider');
    if (slider.hasClass("slideup"))
        slider.removeClass("slideup").addClass("slidedown");
     else
        slider.removeClass("slidedown").addClass("slideup");
    });
};

Answer 3

这是你想要的吗？

$(document).ready(function(){
    $(".trigger").click(function(){
        $(this).siblings(".slider").find(".more").slideToggle();
    });
});
