Javascript函数将颜色名称转换为十六进制代码

问题描述

是否有一个内置函数将名称转换为其十六进制表示的颜色？
像我想传递'白'并收到'#FFFFFF'。我真的想避免编码所有百如果自己：）

Is there a built-in function that would convert a color by name into its hex representation?Like I want to pass 'white' and receive '#FFFFFF'. I really want to avoid coding all hundred if's myself :)

推荐答案

不，但使用您可以创建一个。像这样：

No, but using the list here you could create one. Something like this:

function colourNameToHex(colour)
{
    var colours = {"aliceblue":"#f0f8ff","antiquewhite":"#faebd7","aqua":"#00ffff","aquamarine":"#7fffd4","azure":"#f0ffff",
