1. 根据下标获取对应的classname,实现点击按钮触发当前块的点击事件

<div class="right" @click="meetingfileVisible(index)">
  <span class="foldIcon">
     <i class="el-icon-caret-bottom"></i>
  </span>
</div>
<div class="meeting-file">
  <span>与现实生活一致</span>
</div> 
            


                

                    1
                

                

                    2
                

                

                    3
                

                

                    4
                

                

                    5
                

                

                    6
                

                

                    7
                

                

                    8
                

            

.meeting-file{ display:none; } 
            


                

                    1
                

                

                    2
                

                

                    3
                

            

meetingfileVisible(index) { $(".meeting-file").eq(index).slideToggle("slow"); var cal =$(".foldIcon").eq(index).children("i").attr("class"); cal = cal === 'el-icon-caret-bottom' ? 'el-icon-caret-top' : 'el-icon-caret-bottom'; $(".foldIcon").eq(index).children("i").attr("class", cal); }, 
            


                

                    1
                

                

                    2
                

                

                    3

                    5
