I write to you should have ended, but we are unlikely to show a checkbox to switch animation in real time function button operation requires general or animation Here is the code jq actually operated by .animate jq of () better but I was white so I stole a lazy (ps: Well, in fact, is not) directly .css ()

JavaScript code

   $("#btn1").on("click",function () {
       if($(this).text()==="完成"){
           $(".circle").css({'animation':'circle 1s ease-in-out','animation-fill-mode':'forwards'});
           $(".tick").css({'animation':'tick .8s ease-out','animation-fill-mode':'forwards','animation-delay':'.95s'});
           $("h2").css({'animation':'.6s title ease-in-out','animation-fill-mode':'forwards','animation-delay':'1.2s'})
           $(this).text("Cancel " 
           $ ({the else
       })".circle").css({'animation':'none','animation-fill-mode':'none'});
           $(".tick").css({'animation':'none','animation-fill-mode':'none'});
           $("h2").css({'animation':'none','animation-fill-mode':'none'})
           $(this).text("完成")
       }
   });

Oh yeah, and one more thing to remember to give people a primary UP key triple (BV1ME411F7BG)
