1、js
var Color = function () { //将hex颜色值str转化成rgb数组 this.HexToRgb = function (str) { var r = /^\#?[0-9a-f]{6}$/; //test方法检查在字符串中是否存在一个模式,如果存在则返回true,否则返回false if (!r.test(str)) return window.alert("输入错误的hex颜色值"); //replace替换查找的到的字符串 str = str.replace("#", ""); //match得到查询数组 var hxs = str.match(/../g); alert(‘bf‘+hxs) for (var i = 0; i < 3; i++) hxs[i] = parseInt(hxs[i], 16); alert(parseInt(80, 16)) return hxs; } //将rgb颜色值为a,b,c转化成hex颜色值 this.RgbToHex = function (a, b, c) { var r = /^\d{1,3}$/; if (!r.test(a) || !r.test(b) || !r.test(c)) return window.alert("输入错误的rgb颜色值"); var hexs = [a.toString(16), b.toString(16), c.toString(16)]; for (var i = 0; i < 3; i++) if (hexs[i].length == 1) hexs[i] = "0" + hexs[i]; return "#" + hexs.join(""); } //得到hex颜色值为color的加深颜色值,level为加深的程度,限0-1之间 this.getDarkColor = function (color, level) { var r = /^\#?[0-9a-f]{6}$/; if (!r.test(color)) return window.alert("输入错误的hex颜色值"); var rgbc = this.HexToRgb(color); //floor 向下取整 for (var i = 0; i < 3; i++) rgbc[i] = Math.floor(rgbc[i] * (1 - level)); return this.RgbToHex(rgbc[0], rgbc[1], rgbc[2]); } //得到hex颜色值为color的减淡颜色值,level为减淡的程度,限0-1之间 this.getLightColor = function (color, level) { var r = /^\#?[0-9a-f]{6}$/; if (!r.test(color)) return window.alert("输入错误的hex颜色值"); var rgbc = this.HexToRgb(color); for (var i = 0; i < 3; i++) rgbc[i] = Math.floor((255 - rgbc[i]) * level + rgbc[i]); return this.RgbToHex(rgbc[0], rgbc[1], rgbc[2]); } //得到hex颜色值为color的web安全色 this.getWebSafeColor = function (color) { var r = /^\#?[0-9a-f]{6}$/; if (!r.test(color)) return window.alert("输入错误的hex颜色值"); var rgbc = this.HexToRgb(color); for (var i = 0; i < 3; i++) { var q1 = Math.floor(rgbc[i] / 51) * 51; //ceil向上取整 var q2 = Math.ceil(rgbc[i] / 51) * 51; //abs绝对值 if (Math.abs(q1 - rgbc[i]) <= Math.abs(q2 - rgbc[i])) rgbc[i] = q1; else rgbc[i] = q2; } return this.RgbToHex(rgbc[0], rgbc[1], rgbc[2]); } } //使用方法 insetpane("drakcolor", test.getDarkColor(v, 0.2));
2、php
//hex颜色加深减淡 function changeColor($hex, $type=‘no‘){ if($hex < 0 || hexdec($hex) > hexdec(‘ffffff‘)) { $hex = DIY_COLOR; } $rgb = hexToRgb($hex); if($type==‘+‘){ for ($i = 0; $i < 3; $i++) { $re[$i] = floor((255 - $rgb[$i]) * DIY_COLOR_LEVEL + $rgb[$i]); } $re = rgbToHex($re); }elseif($type==‘-‘){ for ($i = 0; $i < 3; $i++) { $re[$i] = floor($rgb[$i] * (1 - DIY_COLOR_LEVEL)); } $re = rgbToHex($re); } else{ $re = $hex; } return $re; } //hex颜色转RGB function hexToRgb($hex){ $hex = str_replace(‘#‘, ‘‘, $hex); $rgb[0] = hexdec($hex[0].$hex[1]); $rgb[1] = hexdec($hex[2].$hex[3]); $rgb[2] = hexdec($hex[4].$hex[5]); return $rgb; } //RGB颜色转hex function rgbToHex($rgb){ return sprintf(‘%02x‘, $rgb[0]) . sprintf(‘%02x‘, $rgb[1]) . sprintf(‘%02x‘, $rgb[2]); }
