进度条 ​

img 加载失败显示默认图片 ​

scss
img {
  width: 200px;
  height: 200px;
  vertical-align: middle;

  &:after {
    content: '';
    display: inline-block;
    position: absolute;
    z-index: 2;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-size: 100%;
    background: #fff url('../../assets/logo2.jpg') no-repeat;
  }
}

修改多选框的样式 ​

根据后台返回的处理状态显示不同的样式，同时可以点击更改状态

css
.input-color + label {
  display: block;
  width: 20px;
  height: 20px;
  cursor: pointer;
  position: absolute;
  top: 8px;
  left: 30px;
  background-color: #999;
  border-radius: 4px;
}

.input-color:checked + label::before {
  display: block;
  content: '√';
  text-align: center;
  font-size: 16px;
  color: white;
  background-color: #c00;
  border-radius: 4px;
}

如果表格的某一行的状态是 true

js
if(item.processResult) {
<td>
    <input type="checkbox" class="input-color" checked>
    <label for="input-color" onclick="toggleStatus('{{item.id}}',false)"></label>
</td>
}

如果表格的某一行的状态是 false

js
if(!item.processResult) {
<td>
    <input type="checkbox" class="input-color">
    <label for="input-color" onclick="toggleStatus('{{item.id}}',true)"><span style="color: #fff;">√</span></label>
</td>
}

点击某一条数据可以切换状态

html
<script>
  function toggleStatus(statusId, status) {
    var jsonData = {
      id: statusId,
      processResult: status
    };
    postURL('/business/feedback/updateProcessResultById', JSON.stringify(jsonData), function (data) {
      if (data.success) {
        getFeedBackList();
      } else {
        console.log('error');
      }
    });
  }
</script>

换行显示后端返回的数据 ​

1、可以使用 CSS 样式 ​

css
white-space: pre-line;
  • white-space: pre-line，把多个空格合并成一个
  • white-space: pre-wrap，会保留所有空格

2、如果有\n 可以使用 br 标签替换 ​

html
<script>
  var str =
    '职位描述: 诚聘20名商务模特：\n岗位要求：年龄在18-26周岁之间，身高在165cm以上。\n有良好的形象和气质，颜值较高，有才艺、有经验者优先，无经验可以提供免费培训。 ';
  res = str.replace(/\n+/g, '<br/>');
  document.write(res);
</script>

3、文本域 textarea ​

若是在文本域中显示，默认会首行缩进 2 个空格，只需将 textarea 标签写在一行即可

css
<textarea rows="10" cols="50"></textarea>

放射性条状物 ​

核心在clip-path: polygon()属性

html
<div class="box"></div>

<style>
  .box {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 500px;
    height: 500px;
    background-color: #ffb782;
    border-radius: 20px;
  }

  .box::before {
    position: absolute;
    top: 0;
    left: 0;
    background-color: #ffa766;
    width: 100%;
    height: 100%;
    content: '';
    clip-path: polygon(
      20% 0%,
      5% 0,
      50% 50%,
      0 28%,
      0 15%,
      50% 50%,
      0 40%,
      0 49%,
      50% 50%,
      0 58%,
      0 68%,
      50% 50%,
      0 80%,
      0 96%,
      50% 50%,
      15% 100%,
      0 190%,
      50% 50%,
      42% 100%,
      70% 178%,
      50% 50%,
      70% 100%,
      100% 120%,
      50% 50%,
      100% 97%,
      100% 84%,
      50% 50%,
      100% 73%,
      100% 62%,
      50% 50%,
      100% 56%,
      100% 48%,
      50% 50%,
      100% 41%,
      100% 32%,
      50% 50%,
      100% 22%,
      100% 7%,
      50% 50%,
      85% 0,
      66% 0,
      50% 50%,
      50% 0,
      33% 0,
      50% 50%
    );
  }
</style>

文字有下划线背景 ​

鼠标移入有背景色填满文字的过渡动画

css
/* <a href="#">hello world</a> */

a {
  color: rgb(15, 15, 15);
  text-decoration: none;
  outline: none;
  background-color: transparent;

  padding: 2px 0px 1px;
  background-image: linear-gradient(
    transparent 0%,
    transparent calc(50% - 9px),
    rgba(0, 255, 0, 0.5) calc(50% - 9px),
    rgba(0, 255, 0, 0.5) 100%
  );
  transition: background-position 120ms ease-in-out 0s, padding 120ms ease-in-out 0s;
  background-size: 100% 200%;
  background-position: 0px 0px;
  word-break: break-word;
}
a:hover {
  background-image: linear-gradient(
    transparent 0%,
    transparent calc(50% - 9px),
    rgb(0, 255, 0) calc(50% - 9px),
    rgb(0, 255, 0) 100%
  );
  background-position: 0px 100%;
}

元素从左往右渐显 ​

让元素从上往下，或者从左往右渐显出来。可以用伪元素遮盖住元素内容，然后用动画改变伪元素的宽或高

css
/* <div class="box">天下无双</div> */

.box {
  position: relative;
  padding: 5px;
  display: inline-block;
  border: solid 1px;
  font-size: 1.5rem;
}

.box::after {
  content: ' ';
  background-color: #fff;
  position: absolute;
  top: -1px;
  right: -1px;
  width: calc(100% + 2px);
  height: calc(100% + 2px);
  animation: slide 3s ease-in forwards;
}

@keyframes slide {
  to {
    width: 0;
  }
}
  • 如果元素有 border，伪元素的宽高要设为 100%加上 border，对应的 top 和 right 要设置为负的 border 宽度。
  • 因为动画中的文字元素是从左往右显现，伪元素的宽度需要从左往右缩小，所以我们需要将伪元素的固定点设置在右上角或者右下角，即：设置 top/bottom 和 right 属性；如果动画要从右往左显现，则需要设置 top/bottom 和 left 属性；同样，如果从上往下显现，那么就设置 left/right 和 bottom 属性。

还可以使用clip-path实现效果

css
.box {
  position: relative;
  display: inline-block;
  padding: 5px;
  border: solid 1px;
  font-size: 1.5rem;
  clip-path: polygon(0% 0%, 0% 0%, 0% 100%, 0% 100%);
  animation: slide 2s forwards;
}

@keyframes slide {
  to {
    clip-path: polygon(0% 0%, 100% 0%, 100% 100%, 0% 100%);
  }
}

网站置灰 ​

如果是主流浏览器添加 filter 滤镜

css
.gray {
  filter: grayscale(0.95);
}

IE10 以下

css
filter: gray;

IE11 和 IE10 去掉了filter: gray属性，但是又不支持最新的filter: grayscale()。

一般使用 grayscale.js（原链接已失效，可网上查找） 处理，不支持置灰：图片地址是 http 协议、hover、伪元素

js
var navStr = navigator.userAgent.toLowerCase();
if (navStr.indexOf('msie 10.0') !== -1 || navStr.indexOf('rv:11.0') !== -1) {
  grayscale($('body'));
}

修改滚动条样式 ​
