之前老板让做一个登陆后可以显示一个打钩的效果百度死活搜不到今天在B站看到的一个视频居然有根据需求改进了一下废话不多说先看效果！

html代码

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>打钩动画</title>

</head>

<body>

<div id="d1">

    <input type="checkbox" style="display: none" id="love1" />

    <label for="love1" id="btn1" >完成</label>

<svg width="200px" height="200px">

    <circle r="90" class="circle" fill="none" stroke="#2de540" stroke-width="10" cx="100" cy="100" stroke-linecap="round" transform="rotate(-90 100 100) " ></circle>

    <polyline fill="none" stroke="#2de540" stroke-width="10" points="44,107 86,137 152,69" stroke-linecap="round" stroke-linejoin="round" class="tick" ></polyline>

</svg>

<h2 style="text-align: center;width: 200px">成功</h2>

</div>

</body>



<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>

</html>

css代码

h2 {

        font-family: Helvetica;

        font-size: 30px;

        margin-top: 20px;

        color: #333;

        opacity: 0;

    }

    input[type="checkbox"]:checked+ label ~ h2 {

        animation: .6s title ease-in-out;

        animation-delay: 1.2s;

        animation-fill-mode: forwards;

    }

    .circle {

        stroke-dasharray: 1194;

        stroke-dashoffset: 1194;

    }

    input[type="checkbox"]:checked + label + svg .circle {

        animation: circle 1s ease-in-out;

        animation-fill-mode: forwards;

    }

    .tick {

        stroke-dasharray: 350;

        stroke-dashoffset: 350;

    }

    input[type="checkbox"]:checked + label+ svg .tick {

        animation: tick .8s ease-out;

        animation-fill-mode: forwards;

        animation-delay: .95s;

    }

    @keyframes circle {

        from {

            stroke-dashoffset: 1194;

        }

        to {

            stroke-dashoffset: 2388;

        }

    }

    @keyframes tick {

        from {

            stroke-dashoffset: 350;

        }

        to {

            stroke-dashoffset: 0;

        }

    }

    @keyframes title {

        from {

            opacity: 0;

        }

        to {

            opacity: 1;

        }

    }

    label {

        display: inline-block;

        height: 38px;

        width: 38px;

        line-height: 38px;

        padding: 0 18px;

        background-color: #1E9FFF;

        color: #fff;

        white-space: nowrap;

        text-align: center;

        font-size: 14px;

        border: none;

        border-radius: 2px;

        cursor: pointer;

    }

    #d1 {

        display: flex;

        justify-content: center;

        min-height: 100px;

        flex-direction: column;

    }

写到这里本来应该就结束了但是我们在真正实现功能的时候不太可能用 checkbox切换动画效果的显示一般还是需要按钮操作动画效果下面是jq操作的代码其实用jq的.animate()更好一些但是我是小白所以就偷了个懒 (ps:好吧其实是不会)直接用.css()

JavaScript代码

  $("#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("取消")

       }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")

       }

   });
