30秒学会 JavaScript 片段 – HSL to array

Converts an hsl() color string to an array of values.

• Use String.prototype.match() to get an array of 3 string with the numeric values.
• Use Array.prototype.map() in combination with Number to convert them into an array of numeric values.

代码实现

const toHSLArray = hslStr => hslStr.match(/\d+/g).map(Number);

toHSLArray('hsl(50, 10%, 10%)'); // [50, 10, 10]
