技术版本如下：

vue 2.6.14
less 3.13.1
element-ui 2.15.6
less-loader 5.0.0

需求：

支持RGB、HEX编码、支持吸管吸取颜色、颜色选择器、颜色模板、透明度、色板、线性渐变颜色

效果图：

1.引入选择器的color-all文件

<template><div><div><div class="colorpicker-box" :style="{background:handStyle()}"></div></div><h3>带编码显示的color选择器</h3><div>  <ColorPicker:data="pickerColor"@update:isLinear="pickerColor.isLinear = $event"@update:direction="pickerColor.direction = $event"@update:leftColor="handUpdateElement($event, 0)"@update:rightColor="handUpdateElement($event, 1)"></ColorPicker></div><h3>无编码显示的color选择器</h3><div><ColorPicker:data="pickerColor":isText="false"@update:isLinear="pickerColor.isLinear = $event"@update:direction="pickerColor.direction = $event"@update:leftColor="handUpdateElement($event, 0)"@update:rightColor="handUpdateElement($event, 1)"></ColorPicker></div></div>
</template>
<script>
import ColorPicker from '@/components/color-modal/color-picker.vue'
export default {components: {ColorPicker,},data() {return {pickerColor: {isLinear: false, //是否线性color: ['#334251'], //选择的颜色direction: 'right', //方向},}},methods: {handStyle() { return this.pickerColor.isLinear ? `linear-gradient(to ${this.pickerColor.direction},${this.pickerColor.color[0]} ,${this.pickerColor.color.length >= 2 ? this.pickerColor.color[1] : '#AE7DFF'})` : this.pickerColor.color[0]},handUpdateElement(value, cursor = null) {this.$set(this.pickerColor.color, cursor, value)},},
}
</script><style lang="less" scoped>
.colorpicker{&-box{width: 200px;border-radius: 5px;height: 30px;}div{padding: 10px;}
}</style>

2.重点，选择器的封装组件文件color-picker.vue

4.其中utils文件夹里的两个文件如下

message.js

import { Message, MessageBox } from 'element-ui';let message = {message: function(str, type = 'success') {Message[type](str);},confirm: function(text, title = '提示', confirm = null, cancel = null) {MessageBox.confirm(text, title, {confirmButtonText: '确定',cancelButtonText: '取消',type: 'warning'}).then((res) => {confirm && confirm(res);}).catch((res) => {cancel && cancel(res);});}
};export default message;

util.js

//防抖
export const  debounce=(fn, t) =>{const delay = t || 100;let timer = null;return function() {const args = arguments;const context = this;if (timer) {clearTimeout(timer);}timer = setTimeout(() => {timer = null;fn.apply(context, args);}, delay);};
}

5.重点：elementStyle.css样式文件，用于更改选择器的覆盖颜色

elementStyle.css文件需要在main.js引入

import '@/assets/css/elementStyle.css'

6.elementStyle.css代码如下

.el-popover{background: #303030 ;color: #ffffff;font-size: 12px;border: 1px solid rgba(255, 255, 255, 0.06);padding: 5px 5px;min-width: 40px;}.popper__arrow {display: none !important;
}
.el-dropdown-menu{background: #303030;border: 1px solid rgba(255, 255, 255, 0.06);
}
.el-dropdown-menu__item {color: #fff;width: 70px;}.el-dropdown-menu__item:focus,.el-dropdown-menu__item:not(.is-disabled):hover {background: #373739FF;}

7.引入的图片和svg图片在项目源码包里src/assets/image路径下

8.注意点

如果下载源码的话先

先执行
yarn install
再执行
yarn serve

运行成功后直接使用
