jquery - Javascript - Click to rotate image infinitely and click again to stop -


i've been trying figure out how script rotate image infinitely onclick , stop when click again. can modify that? 

$(function() {      var $rota = $('.spin'),         degree = 0,         timer;      function rotate() {             $rota.css({ transform: 'rotate(' + degree + 'deg)'});         // timeout increase degrees:         timer = settimeout(function() {             ++degree;             rotate(); // loop         },5);     }      rotate();    // run it!  });

you create bool determine if element has been clicked, change on click , stop process if click has happened. 

$(function() {      var $rota = $('.spin'),         degree = 0,         clicked = false,         timer;      $rota.on('click', function() { clicked = true; return false; } );      function rotate() {          if ( clicked )                $rota.css({ transform: 'rotate(' + degree + 'deg)'});             // timeout increase degrees:             timer = settimeout(function() {                ++degree;                rotate(); // loop             },5);         }          rotate();    // run it! });
