javascript - Bootstrap Collapse missed event when mousing through quickly -

-

i have run problem when using bootstraps collapse , hover event. there small delay (not sure if supposed happen) , if mouse out before delay complete mouse out not caught. can same thing mousing out , in before delay.

i have created js-fiddle example of happening.

https://jsfiddle.net/3g2gdyn4/4/

<body>     <div class="box">         <div class="box_area">         </div>         <div class="box_dropdown">            <ul>                <li>test</li>            </ul>         </div     </div> </body>  $(document).ready(function () {     $(".box_area").hover(function(e) {         $(".box_dropdown").collapse("show")     }, function(e) {         $(".box_dropdown").collapse("hide")     }); })  .box_area {     width: 200px;     height: 200px;     border: solid black 1px; }  .box_dropdown {     display: none;     width: 200px;     border: solid red 1px; }

frameworks , extensions:

  • //netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js

external refrences:

  • //netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css
  • //netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js

i have tried .show , .hide instead of .collapse run different bug when sized phones. not option unless can solve bug. lot harder show example because shows touch screens.

give shot: fiddle

i changed way javascript functions. instead of triggering .collapse() plugin bootstrap we're triggering toggling of in class. effect same, , bootstrap uses collapse system, go different way in situation.

you'll have full screen snippet see working.

$(document).ready(function () {      $(".box_area").hover(function(e) {          $('.box_dropdown').toggleclass('in');      }, function(e) {          $('.box_dropdown').toggleclass('in');      });  })
.box_area {      width: 200px;      height: 200px;      border: solid black 1px;  }    .box_dropdown {      display: none;      width: 200px;      border: solid red 1px;  }
<script src="https://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>  <link href="https://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet"/>  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <body>      <div class="box">          <div class="box_area">          </div>          <div class="box_dropdown collapse">              <ul>                  <li>test</li>              </ul>          </div>      </div>  </body>
