问题描述
我需要一个颜色转换器将hsl转换为rgb和十六进制值。我打算做类似这个。我正在使用jquery和jquery ui range slider。这是我的代码:
I need a color converter to convert from hsl to rgb and hex value. I am going to do similar like this. I am using jquery and jquery ui range slider for this. Here is my code:
$(function() {
$( "#hsl_hue_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal",
slide: function( event, ui ) {
var hsl_hue = ui.value;
}
});
});
$(function() {
$( "#hsl_saturation_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal",
slide: function( event, ui ) {
var hsl_saturation = ui.value;
}
});
});
$(function() {
$( "#hsl_light_range" ).slider({
min: 0,
max: 100,
value: 0,
range: false,
animate:"slow",
orientation: "horizontal",
slide: function( event, ui ) {
var hsl_light = ui.value;
}
});
});
我想要这样的解决方案:
I want the solution like this:
转换器的输入可以由变量给出。喜欢 hsl_hue
hsl_saturation
hsl_light
。
the input to converter can be given by the variables. like hsl_hue
hsl_saturation
hsl_light
.
有没有办法做到这一点?
如果没办法,我该怎么办?
Is there any way to do this?
if no way, what can I do?
推荐答案
HSL到RGB:
HSL to RGB:
/**
* Converts an HSL color value to RGB. Conversion formula
* adapted from http://en.wikipedia.org/wiki/HSL_color_space.
* Assumes h, s, and l are contained in the set [0, 1] and
* returns r, g, and b in the set [0, 255].
*
* @param {number} h The hue
* @param {number} s The saturation
* @param {number} l The lightness
* @return {Array} The RGB representation
*/
function hslToRgb(h, s, l){
var r, g, b;
if(s == 0){
r = g = b = l; // achromatic
}else{
var hue2rgb = function hue2rgb(p, q, t){
if(t < 0) t += 1;
if(t > 1) t -= 1;
if(t < 1/6) return p + (q - p) * 6 * t;
if(t < 1/2) return q;
if(t < 2/3) return p + (q - p) * (2/3 - t) * 6;
return p;
}
var q = l < 0.5 ? l * (1 + s) : l + s - l * s;
var p = 2 * l - q;
r = hue2rgb(p, q, h + 1/3);
g = hue2rgb(p, q, h);
b = hue2rgb(p, q, h - 1/3);
}
return [Math.round(r * 255), Math.round(g * 255), Math.round(b * 255)];
}
