javascript - jQuery 折叠隐藏另一个元素

Question

我在一个简单的折叠系统中工作并且它工作正常......但是每个折叠元素中都有一个额外的元素，如夏季 p 标签，当我单击 p 标签隐藏和完整内容将显示的任何元素时......它确实有效，但也会影响其他元素......但它不应该......

html代码为:

    <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
      <div class="panel panel-default">
        <div class="panel-heading" role="tab" id="headingOne">
          <h4 class="panel-title">
            <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
              Collapsible Group Item #1
            </a>
          </h4>
        </div>
        <p class="summery">this is summery</p>
        <div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne">
          <div class="panel-body">

JS代码:

$('.panel-heading > .panel-title').click(function(){
    $('.panel > p.summery').toggle();

});

Answer 1

你需要:

$(this).closest('.panel').find('> p.summery').toggle();

相反:

$('.panel > p.summery').toggle();

DEMO

只需选择每个面板对应的元素即可。
