javascript - Jquery rotation rotate img on click -

-

good evening. @ moment using jquery rotate plugin allow image rotate clicked, image rotates 180 degrees once button clicked again go original position image keep 180 degrees rotation , can't figure out way of putting 0 degree position. can help? here code:

html:

<div class="box_one">         <div class="box_one_second" id="box-appear">           <p>some text</p>         </div>         <button id="button-one"><img id="arrowdown"src="#"/>        </button> </div>

jquery:

$(document).ready(function(){         $("#button-one").click(function(){           $(".box_one_second").toggle(200);                 $("#arrowdown").css('rotate',180);         });       });

i can see i'm rotating 180 this, how able reverse once user clicks button go original pos. thanks

i'd recommend use jquery's toggleclass adding/removing class. can control rotation plain css.

img.rotate {    transform: rotate(180deg);  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>    <img src='http://lorempixel.com/400/200/' />  <button onclick="$('img').toggleclass('rotate')">rotate</button>
