所以我在同一页面上有许多具有相同类的 div。我想根据自己的选择为每个人添加不同的背景(有 5-6 个随机背景)
我在互联网上找到了这段代码。但它为所有 div 选择相同的随机颜色。

//specify list of random background colors to apply to CSS class "randomcolor"
//For each entry, you can optionally specify a text and link color via the syntax:
// "BackgroundColor:TextColor" OR "BackgroundColor:TextColor:LinkColor"
var randombgcolors=["green:white:yellow", "#DDF4FF", "#FFFF97", "#CFFF9F"]
var rbcssrule=""
var randomnum=Math.floor(Math.random()*randombgcolors.length)
if (randombgcolors[randomnum].indexOf(":")!=-1){

else
rbcssrule="background-color: "+randombgcolors[randomnum]+";"
document.write('<style type="text/css">\n')
document.write('.randomcolor{'+rbcssrule+'}\n')

document.write('<\/style>')
