为动态生成的div设置不同的颜色

javascriptphpjqueryhtmlcss
3

我在一个页面上有一个功能。

1：编辑语言

1：编辑语言

当页面加载时，在编辑语言部分，语言div（英语、德语、法语）的颜色需要随机设置。

例如：英语-蓝色，德语-红色，法语-绿色

如果用户更改排名下拉菜单（1到5），则更改语言div的颜色。

目前颜色正在div中改变，但在页面加载时未显示出来。请查看我的演示和图片。

@sam，你能告诉我正确的行为应该是什么吗？ - Rajesh

谢谢，它有效。我们如何为它添加动画效果（animate()）？如果您有时间，请帮助我。 - Sarath TS
不确定你所说的'(animate()) this'是什么意思，但也许这个例子可以帮助你入门： http://jsfiddle.net/Lr6a5d2v/40/ 它使用了jQuery Color插件。 - The fourth bird
