按钮点击出现涟漪效果

点击涟漪效果

前天看到b站上一个视频，up主实现了一个按钮点击然后以点击点为圆心出现一个圆，然后这个圆慢慢变大最后消失，感觉很吊的样子，我觉得我也能实现，废话不多说，干就完了。

。。。。。。。。。。。。。。。

经过两分钟的编写，终于实现了（如下图：点击了第二个按钮，然后出现了一个涟漪）

然后上代码

html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>涟漪</title>
    <link rel="stylesheet" href="../css/base.css" />
    <link rel="stylesheet" href="../css/button.css" />
  </head>
  <body>
    <div id="app">
      <ul @click="cel">
        <li>
          <div class="btn-cel" @click="cel">
            click
          </div>
        </li>
        <li>
          <div class="btn-cel red" @click="cel">
            click
          </div>
        </li>
        <li>
          <div class="btn-cel blue" @click="cel">
            click
          </div>
        </li>
      </ul>
    </div>
  </body>
  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
  <script>
    new Vue({
      el: "#app",
      methods: {
        cel(tag) {
          let x = tag.offsetX;
          let y = tag.offsetY;
          let ripples = document.createElement("span");
          ripples.style.left = x + "px";
          ripples.style.top = y + "px";
          tag.srcElement.appendChild(ripples);
          setTimeout(() => {
            ripples.remove();
          }, 1000);
        },
      },
    });
  </script>
</html>

base.css:

* {
  margin: 0;
  padding: 0;
}

html,body {
  height: 100vh;
  width: 100vw;
  background-color: #fff;
  font-size: 14px;
  font-family: Arial, Helvetica, sans-serif;
  font-weight: normal;
}

a {
  text-decoration: none;
}
 li {
   list-style: none;
 }
input {
  outline: none;
}

然后是主要的button.css:

#app{
  width: 100%;
  height: 100%;
  background: linear-gradient(to right,#123456 0%,#abcdef 100%);
  display: flex;
  justify-content: center;
  align-items: center;
}
ul{
  width: 300px;
  height: 200px;
  background-color: #fff;
  padding: 20px;
  border-radius: 10px;
  position: relative;
  overflow: hidden;
}
li{
  margin: 20px;
}
.btn-cel{
  width: 100px;
  height: 30px;
  line-height: 30px;
  text-align: center;
  border: 1px solid #abcdef;
  margin: 0 auto;
  text-transform: uppercase;
  font-size: 14px;
  letter-spacing: 2px;
  border-radius: 6px;
  cursor: pointer;
  color: wheat;
  position: relative;
  background: linear-gradient(40deg,#755beaff,#ff72c077);
  overflow: hidden;
}
.red{background: linear-gradient(90deg,#6e1e22ff,#a3949677);}
.blue{background: linear-gradient(90deg,#43129eff,#a8aed477);}
span{
  position: absolute;
  display: inline-block;
  width: 10px;
  height: 10px;
  border-radius: 50%;
  transform: translate(-50%,-50%);
  background-color: #fff000;
  animation: animate 1s linear infinite;
}
@keyframes animate{
  from{width: 1px;height: 1px;opacity: .5;}
  to{width: 100px;height: 100px;opacity: .1;}
}

然后就OK了美滋滋

不过：没有做浏览器兼容问题，谷歌浏览器是没问题的

这个小demo还是让俺复习到了一些知识点的：

1.vue点击事件怎么获取到当前元素：tag.srcElement

2.背景渐变：background: linear-gradient(to right,#123456 0%,#abcdef 100%);

3.c3动画：

animation: animate 1s linear infinite;

@keyframes animate{

from{width: 1px;height: 1px;opacity: .5;}

to{width: 100px;height: 100px;opacity: .1;}

}

over！
