是否有内置函数可以将颜色按名称转换为十六进制表示形式？ 就像我想通过'白'并接收'#FFFFFF'一样。我真的想避免编码全部，如果是我自己：）

不，但使用list here你可以创建一个。像这样：
function colourNameToHex(colour)

这将以RGB形式呈现给您 - 您应该能够轻松地进行十六进制转换。
d = document.createElement("div");
d.style.color = "white";
document.body.appendChild(d)
//Color in RGB
window.getComputedStyle(d).color
所有浏览器都不支持Get Computed样式。
答案 2 :(得分：29)
“向DOM添加元素并检查其ComputedStyle”方法对我来说似乎有点复杂 - 你需要添加它并检查它并记得删除它并且你只是为了计算颜色而改变DOM它会引起回流吗？所以这是基于临时（并且从未呈现）<canvas>：
function colorToRGBA(color) {
// Returns the color as an array of [r, g, b, a] -- all range from 0 - 255
// color must be a valid canvas fillStyle. This will cover most anything
// you'd want to use.
// Examples:
// colorToRGBA('red') # [255, 0, 0, 255]
// colorToRGBA('#f00') # [255, 0, 0, 255]
var cvs, ctx;
cvs = document.createElement('canvas');
cvs.height = 1;
cvs.width = 1;
ctx = cvs.getContext('2d');
ctx.fillStyle = color;
ctx.fillRect(0, 0, 1, 1);
return ctx.getImageData(0, 0, 1, 1).data;
}
function byteToHex(num) {
// Turns a number (0-255) into a 2-character hex number (00-ff)
return ('0'+num.toString(16)).slice(-2);
}
function colorToHex(color) {
// Convert any CSS color to a hex representation
// Examples:
// colorToHex('red') # '#ff0000'
// colorToHex('rgb(255, 0, 0)') # '#ff0000'
var rgba, hex;
rgba = colorToRGBA(color);
hex = [0,1,2].map(
function(idx) { return byteToHex(rgba[idx]); }
).join('');
return "#"+hex;
}
请注意，这可以让你使用任何有效的画布fillStyle，所以如果你想从图像中弄出一个1像素的图案，它也会告诉你它的颜色。
我已经在IE，Chrome，Safari和Firefox的合理现代版本中对此进行了测试。

此处使用浏览器为您计算的功能
function getHexColor(colorStr) {

var colors = window.getComputedStyle( document.body.appendChild(a) ).color.match(/\d+/g).map(function(a){ return parseInt(a,10); });
document.body.removeChild(a);
return (colors.length >= 3) ? '#' + (((1 << 24) + (colors[0] << 16) + (colors[1] << 8) + colors[2]).toString(16).substr(1)) : false;
}
getHexColor('teal') // returns #008080

这是一个全能的解决方案，可以在每个浏览器中完全满足您的需求，这些浏览器是100％编程的，再见巨大的静态名称表和十六进制值！：
// Here is the solution tied together as a native String native extension using
// MooTools, though you can implement the same thing in whatever framework you prefer:
(function(String){
var valueMatch = {
'rgb(0,0,0)': { 'black': ' ', 'rgb(0,0,0)': ' ' },
'rgba(0,0,0,0)': { 'transparent': ' ', 'rgba(0,0,0,0)': ' ' },
'#ffffff': { 'transparent': ' ' },
'transparent': { 'transparent': ' ' }
},
colorFromProbe = function(color){
color = color.toString();
if(!color.match(/^#.+$|^[^0-9]+$/)) return color;
var probe = ($('moo_color_probe') || new Element('textarea', {
'id': 'moo_color_probe',
'styles': {
'display': 'none',
'color': 'transparent'
}
}).inject(document.body, 'after'));
try{ probe.setStyle('color', color) } catch(e){ return color } //IE throws an error instead of defaulting the style to some color or transparent when the value is unrecognized
var computed = (Browser.ie) ? ieColorToHex(probe) : (Browser.opera) ? probe.style.color : probe.getComputedStyle('color'),
match = valueMatch[computed.replace(/ /g, '')];
probe.setStyle('color', 'transparent');
if((!Browser.ie || Browser.ie9) && color == 'transparent' && (match && match['transparent'])) return 'rgba(0, 0, 0, 0)';
return (computed == 'transparent' || match && !match[color.replace(/ /g, '')]) ? color : computed;
},
ieColorToHex = function(probe){ // Special IE mojo, thanks to Dean Edwards for the inspiration, his code used a pop-up window to test the color, I found you can simply use a textarea instead ;)
var value = probe.set('value', '').createTextRange().queryCommandValue("ForeColor");
value = (((value & 0x0000ff) << 16) | (value & 0x00ff00) | ((value & 0xff0000) >>> 16)).toString(16);
return "#000000".slice(0, 7 - value.length) + value;
};
String.implement({
colorToRgb: function(){
var color = colorFromProbe(this);
return (color.charAt(0) == '#') ? color.hexToRgb() : color;
},
colorToHex: function(){
var color = colorFromProbe(this);
return (color.test('rgb')) ? color.rgbToHex() : color;

@dlauzon建议我将我的评论转换成答案。谢谢你的建议！这是：）
function standardize_color(str){
var ctx = document.createElement('canvas').getContext('2d');
ctx.fillStyle = str;
return ctx.fillStyle;
}
function standardize_color(str){
var ctx = document.createElement("canvas").getContext("2d");
ctx.fillStyle = str;
return ctx.fillStyle;
}
document.getElementById("myspan1").innerHTML = standardize_color("red");
document.getElementById("myspan2").innerHTML = standardize_color("PeachPuff");
document.getElementById("myspan3").innerHTML = standardize_color("PaleGoldenRod");
document.getElementById("myspan4").innerHTML = standardize_color("RGB(123,234,142)");
document.getElementById("myspan5").innerHTML = standardize_color("HSL(284,6%,49%)");span { font-weight:800; }The color named "Red" has a code of: <span id="myspan1">(requires js)</span>.<br>
...and color "PeachPuff"'s code is: <span id="myspan2">(requires js)</span>.<br>
...and "PaleGoldenRod" is: <span id="myspan3">(requires js)</span>.<br><br>
It works with "RGB(123,234,142)" too: <span id="myspan4">(needs js)</span>
and therefore with: "HSL(284,6%,49%)", which is: <span id="myspan5">(requires js)
</span>. Handy!
答案 6 :(得分：6)
您需要依赖getComputedStyle(...)。
使用getComputedStyle的示例：
function convertToHexColor(englishColor) {
// create a temporary div.
var div = $('<div></div>').appendTo("body").css('background-color', englishColor);
var computedStyle = window.getComputedStyle(div[0]);
// get computed color.
var computedColor = computedStyle.backgroundColor;
// cleanup temporary div.
div.remove();
// done.
return computedColor;
// The above returns "rgb(R, G, B)" on IE9/Chrome20/Firefox13.
};
要将“rgb（R，G，B）”转换为#RRGGBB，您可以使用：
function convertRGBDecimalToHex(rgb)
{
var regex = /rgb *\( *([0-9]{1,3}) *, *([0-9]{1,3}) *, *([0-9]{1,3}) *\)/;
var values = regex.exec(rgb);
if(values.length != 4)
{
return rgb; // fall back to what was given.
}
var r = Math.round(parseFloat(values[1]));
var g = Math.round(parseFloat(values[2]));
var b = Math.round(parseFloat(values[3]));
return "#"
+ (r + 0x10000).toString(16).substring(3).toUpperCase()
+ (g + 0x10000).toString(16).substring(3).toUpperCase()
+ (b + 0x10000).toString(16).substring(3).toUpperCase();
}

此函数请求命名的颜色并发送返回十六进制颜色值。 如果不支持指定的颜色（例如“ whyte”），默认情况下会发回黑色，但是在consol上，您会发现警告： 不支持的命名颜色：$ {namedColor}
const namedColorToHex = namedColor => {
const html = document.querySelector("html");
const originalColor = html.style.color;
html.style.color = namedColor;
const rgbFormatBgColor = window.getComputedStyle(html).color;
if (namedColor !== "black" && rgbFormatBgColor === "rgb(0, 0, 0)") {
console.warn(`Not supported named color: ${namedColor}`);
}
html.style.color = originalColor;
const regEx = /(\d+)/g;
const result = rgbFormatBgColor.match(regEx);
let hexColor = `#`;
result.forEach(value => {
let hex = Number(value).toString(16);
if (hex.length === 1) {
hex = `0${hex}`;
}
hexColor += hex;
});
return hexColor;
};

从w3color.js下载并包含w3school。
然后您可以在脚本中使用以下任何功能：
let c = w3color("violet");
c.darker(n)
c.desaturate(n)
c.isDark(n)
c.lighter(n)
c.saturate(n)
c.toCmyk()
c.toCmykString()
c.toCmykStringDecimal()
c.toHexString()
c.toHsl()
c.toHslString()
c.toHslStringDecimal()
c.toHslaString()
c.toHwb()
c.toHwbString()
c.toHwbStringDecimal()
c.toHwbaString()
c.toName()
c.toNcol()
c.toNcolString()
c.toNcolStringDecimal()
c.toNcolaString()
c.toRgb()
c.toRgbString()
c.toRgbaString()

从 Ties 转换为 TypeScript 的解决方案：
export const getHexColorFromLiteral = (colorStr: string) => {
const div = document.createElement('div')
div.style.color = colorStr
document.body.appendChild(div)
const computedColor = window.getComputedStyle(div).color
const matchResult = computedColor.match(/\d+/g)
if (matchResult !== null) {
const colors = matchResult.map((a) => parseInt(a, 10))
document.body.removeChild(div)
return colors.length >= 3
? '#' + ((1 << 24) + (colors[0] << 16) + (colors[1] << 8) + colors[2]).toString(16).substr(1)
: false
}
return false
}
