以原型的方式,给string字符串类型添加方法,用于实现颜色值格式的转换:不习惯使用原型方法的,只要借鉴实现方法就好! 代码如下: var reg = /^#([0-9a-fA-f]{3}|[0-9a-fA-f]{6})$/; /*RGB颜色转换为16进制*/ String.prototype.colorHex = function(){ var that = this; if(/^(rgb|RGB)/.test(that)){ var aColor = that.replace(/(?:\(|
function convertHexToRGB(color) { if (color.length === 4) { let extendedColor = "#" for (let i = 1; i < color.length; i++) { extendedColor += color.charAt(i) + color.charAt(i) }
Introduction Why an article on "colors"? It's the same question I asked myself before writing this series. The fact is, in .NET, there are only two color formats that can be used: the RGB color model and the HSB color model. Those two are encaps
1. Color类 µ 公共静态属性:共13个静态属性,分别代表13种不同的颜色常量. µ 构造函数 ü public Color(int r,int g,int b):以整数形式给出红.绿.蓝三个分量的值,每个分量的范围:0~255 ü public Color(float r,float g,float b):r.g.b均为单精度浮点数.取值范围为0.0f~1.0f ü public Color(int rgb):rgb的16~23位:红色分量:0~7位:蓝色分量,8~15位:绿色分量. 2
在之前的一篇文章<将16进制的颜色转为rgb颜色>中,曾经写过将16进制的颜色转换为rgb颜色. 当然了,今天再看,还是有很多可以优化的地方,所以对之前的代码重构了一遍,并且同时写了一个反向转换(也就是将rgb颜色值转换为字符串形式的16进制的颜色值)函数. 16进制转换rgb: function transferColorToRgb(color) { if (typeof color !== 'string' && !(color instanceof String)) re
CSS COLOR Color Review We've completed our extensive tour of the colors in CSS! Let's review the key information we've learned. There are four ways to represent color in CSS: Named colors - there are 147 named colors, which you can review here. Hexad

将RGB颜色值转换为16进制颜色值,主要是将 R.G.B 值分别转换为对应的十六进制值,填入 #RRGGBB 中. 推荐在线颜色转换工具:http://www.ecjson.com/rgbhex/ 例子: 输入:rgb(176,114,98) 输出:#B07262 代码如下: function colorRGBtoHex(color) { var rgb = color.split(','); var r = parseInt(rgb[0].split('(')[1]); var g = par
