所以我试图在HTML(使用jQuery)中建立一个滑块来将网站的背景从白色变为黑色(其在黑暗项目中的发光)。白色到黑色变色滑块Html?
我一直在寻找互联网,并建立了一个工作滑块的RGB,但不能得到它只是白色的黑色,反之亦然......任何人都知道如何做到这一点?我不想让它成为彩虹的所有颜色,只有两个哈哈!
我的代码如下:

function hexFromRGB(r, g, b) {
var hex = [
r.toString(16),
g.toString(16),
b.toString(16)
];
$.each(hex, function(nr, val) {
if (val.length === 1) {
hex[ nr ] = "0" + val;
}
});
return hex.join("").toUpperCase();
}
function refreshSwatch() {
var red = $("#red").slider("value"),
green = $("#green").slider("value"),
blue = $("#blue").slider("value"),
hex = hexFromRGB(red, green, blue);
$("#swatch").css("background-color", "#" + hex);
}
$(function() {
$("#red, #green, #blue").slider({
orientation: "horizontal",
range: "min",
max: 255,

谢谢那是辉煌,我希望它做的,但投入时来自jsFiddle的HTML不加载?添加至原始文章 – June
您需要将代码放入文档调用(http://learn.jquery.com/using-jquery-core/document-ready/)或页面末尾。 – j08691
嗨,对不起,我以为我有这个想法,但我仍然无法得到文件“准备好”?不知道我会错在哪里我跟着你提供的网页...对不起,很痛苦 – June
