php网站开发说明上海百度推广平台
序言
突发奇想，看到这个特效还不错，就加工了一下，如果也能帮到你，很开心
先上效果图
部分代码讲解
前端生成uuid
function getUUID(len, radix) {var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('')var uuid = []var iradix = radix || chars.lengthif (len) {for (i = 0; i < len; i++) uuid[i] = chars[0 | Math.random() * radix]} else {var ruuid[8] = uuid[13] = uuid[18] = uuid[23] = '-'uuid[14] = '4'for (i = 0; i < 36; i++) {if (!uuid[i]) {r = 0 | Math.random() * 16uuid[i] = chars[(i === 19) ? (r & 0x3) | 0x8 : r]}}}return uuid.join('')
}修改input 原生date icon
input[type=date]::-webkit-calendar-picker-indicator {/*border: 1px solid #0c1622;*//*border-radius: 2px;*//*box-shadow: inset 0 1px #0c1622, 0 1px #0c1622;*//*background-color: #0c1622;*/background-image: url("dateicon2.svg");/*background-image: -webkit-linear-gradient(top, #f0f0f0, #e6e6e6);*//*color: #0c1622;*/}icon
可以去阿里矢量库下载想要的图标
地址：iconfont-阿里巴巴矢量图标库
我使用的是下面这个，但是颜色是白色，因为整个背景图是深色，图标需要浅色。
其他修改
1. 去掉 date 中上下小三角，但是保留 input 类型为 number 的小三角
input[type=date]::-webkit-inner-spin-button { visibility: hidden; }2. 改变日期（文字）的背景色，或添加背景图
input[type=date]::-webkit-datetime-edit { padding: 1px; background: url(../selection.gif); }3. 改变日期（文字）的背景色，或添加背景图
input[type=date]::-webkit-datetime-edit-fields-wrapper { background-color: #eee; }4. 改变 年月日 间距 和 连接符颜色
input[type=date]::-webkit-datetime-edit-text { color: #4D90FE; padding: 0 .3em; }5. 改变 年 的颜色
input[type=date]::-webkit-datetime-edit-year-field { color: purple; }6. 改变 月 的颜色
input[type=date]::-webkit-datetime-edit-month-field { color: blue; }7. 改变 日 的颜色
input[type=date]::-webkit-datetime-edit-day-field { color: green; }8. 改变选择 年月日 按钮
input[type=date]::-webkit-calendar-picker-indicator {border: 1px solid #ccc;border-radius: 2px;box-shadow: inset 0 1px #fff, 0 1px #eee;background-color: #eee;background-image: -webkit-linear-gradient(top, #f0f0f0, #e6e6e6);color: #666;}
