特殊的颜色转换效果与纯jQuery动画//没有ui或其他libary [英] Special color transition effect with pure jQuery animation // no ui or other libary

问题描述

我试图创建没有任何外部插件的jQuery颜色动画。到目前为止，我可以通过jQuery-ui做到这一点，但我想用纯jQuery animate（）

I am trying to create jQuery color animation without any external plugins. So far i could manage to do this with jQuery-ui but i want to learn this way with pure jQuery animate()

有可能在 1.8 1.8 上执行此少代码和没有任何外部jQuery插件？

这里是jsFiddle示例，具有 jQuery 1.7.2和ui

jQuery：

var Text = $('h1');
var Box = $('.box');

Text.click(function() {
    Text.animate({'color':'#f00'},600)
        .delay(200).animate({'color':'#ff0'},600)
        .delay(200).animate({'color':'#000'},600);
});

Box.click(function() {
    Box.animate({'background-color':'#f00'},600)
        .delay(200).animate({'background-color':'#ff0'},600)
        .delay(200).animate({'background-color':'#000'},600);
});

推荐答案

您要求的代码较少， a href =https://github.com/jquery/jquery-color/blob/master/jquery.color.js>相关代码，我使用 Google Closure Compiler ：

You asked for less code, so here is the relevant code which I minified with Google Closure Compiler:

(function(h,m){function n(a,b,c){var d=r[b.type]||{};if(null==a)return c||!b.def?null:b.def;a=d.floor?~~a:parseFloat(a);return isNaN(a)?b.def:d.mod?(a+d.mod)%d.mod:0>a?0:d.max<a?d.max:a}function s(a){var b=f(),c=b._rgba=[],a=a.toLowerCase();j(v,function(d,g){var e,i=g.re.exec(a);e=i&&g.parse(i);i=g.space||"rgba";if(e)return e=b[i](e),b[k[i].cache]=e[k[i].cache],c=b._rgba=e._rgba,!1});return c.length?("0,0,0,0"===c.join()&&h.extend(c,o.transparent),b):o[a]}function p(a,b,c){c=(c+1)%1;return 1>6*c?

这是大约7kb的UTF8没有gzip或其他压缩，并允许你动画的颜色完全一样以前做的与jQuery UI。这意味着，它允许你删除jQuery UI，同时保持相同的代码。

It is about 7kb in UTF8 without gzip or other compressions, and allows you to animate colors exactly as you were previously doing with jQuery UI. That means, it allows you to remove the jQuery UI while keeping the same code.

我还建议您更多地优先考虑开发时间。 7kb在第一负载不会是任何最终用户，没有显着的变化，甚至拨号。这就是为什么我认为重构这浪费时间。没有必要花几个小时/天重新发明轮子。 =]

I'll also suggest to prioritize your development time more. 7kb on a first load won't be a noticeable change for any end-user, not even dial up ones. That's why I consider refactoring this a waste of time. There's no need to spend hours/days reinventing the wheel. =]
