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
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>打钩动画</title> 6 </head> 7 <body> 8 <div id="d1"> 9 <input type="checkbox" style="display: none" id="love1" /> 10 <label for="love1" id="btn1" >完成</label> 11 <svg width="200px" height="200px"> 12 <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> 13 <polyline fill="none" stroke="#2de540" stroke-width="10" points="44,107 86,137 152,69" stroke-linecap="round" stroke-linejoin="round" class="tick" ></polyline> 14 </svg> 15 <h2 style="text-align: center; 200px">成功</h2> 16 17 </div> 18 </body> 19 <!--这里引入你本地的jq--> 20 <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> 21 </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")
}
});
