用JQuery淡入span标签的背景颜色 [英] Fade the background-color of a span tag with JQuery

问题描述

我试图使用JQuery来淡化span标签的背景颜色，以强调发生更改时的情况。我正在考虑代码将在click处理程序中像下面的内容，但我似乎无法得到它的工作。你能告诉我我出错的地方吗？
感谢Russ。

$ $ $ $ $ $ $ $span。fadeOut（slow）.css（background-色 ）VAL（ FFFF99\" ）;

好了，但现在它会淡化背景span标签的颜色和span标签的文本值。我试图淡化背景颜色并让文字可见。可以这样做吗？

解决方案

哦，我没有意识到你想淡化颜色！好的，所以你需要查看jQuery颜色插件：

http://plugins.jquery.com/project/color

https://github.com/jquery/jquery-color/

以下是jQuery文档网站另一个有用的部分： http://docs.jquery.com/Release:jQuery_1.2/Effects#Color_Animations

I我从来没有真正做到这一点，所以我不会尝试给你代码，但我想象色彩插件会给你你需要的功能。

I'm trying to fade the background-color of a span tag using JQuery to emphasize when a change has occured. I was thinking the code would be someting like the following inside the click handler, but I can't seem to get it working. Can you show me where I went wrong? Thanks Russ.

$("span").fadeOut("slow").css("background-color").val("FFFF99");

That's better, but now it fades both the background-color of the span tag and the text value of the span tag too. I'm trying to just fade the background-color and leave the text visible. Can that be done?

解决方案

OH, I didn't realize you wanted to fade the color! OK, so you need to check out the jQuery color plugin:

http://plugins.jquery.com/project/color

https://github.com/jquery/jquery-color/

And here's another helpful section of the jQuery docs site:

http://docs.jquery.com/Release:jQuery_1.2/Effects#Color_Animations

I've never actually done this so I won't try to give you code, but I imagine the color plugin will give you the functionality you need.
