我想知道 DOM 元素是否具有例如颜色：红色的样式。如果这是在内联样式上定义的，就像
<input type="text" style="color:Red">
I can get it easily with JavaScript

But how about if it's defined on a role - I mean as a css class and assign the class to the DOM Element
但是如果它是在一个角色上定义的 - 我的意思是作为一个 css 类并将该类分配给 DOM 元素
With javascript I know I can get the color with some method call computedStyle and give it the name of the property but it brings me the color in RGB numbers mode in Firefox and in IE it gets the color name
使用 javascript 我知道我可以通过一些方法调用来获得颜色并给它属性的名称，但它在 Firefox 中以 RGB 数字模式为我带来颜色，在 IE 中它获得颜色名称

I think that these are the names supported in most browsers, you could store them in a dictionary and look them up: http://www.febooti.com/products/iezoom/online-help/html-color-names-x11-color-chart.html
我认为这些是大多数浏览器支持的名称，您可以将它们存储在字典中并查找它们：http: //www.febooti.com/products/iezoom/online-help/html-color-names-x11-颜色图表.html
The x11 color names are a superset of the ones defined in css.
x11 颜色名称是 css 中定义的颜色名称的超集。

A color name to RGB converter look up table will help, start here: http://web.njit.edu/~walsh/rgb.html.
On the other hand someone might have build it before, so try to google it: https://encrypted.google.com/search?num=100&q=SlateGray1+SlateGray2+inurl%3A.js
RGB 转换器查找表的颜色名称会有所帮助，从这里开始：http: //web.njit.edu/~walsh/rgb.html。
另一方面，之前可能有人构建过它，所以尝试用谷歌搜索它：https: //encrypted.google.com/search?num=100&q=SlateGray1+SlateGray2+inurl%3A.js

Check out the https://www.w3schools.com/lib/w3color.jsconversion script. It is very comprehensive, converting between named colors, hex, hsl, hwb, cmyk, and ncol It does not, however, support colors with alpha
查看https://www.w3schools.com/lib/w3color.js转换脚本。非常全面，可以在命名颜色、hex、hsl、hwb、cmyk、ncol之间进行转换，但是不支持带alpha的颜色
