var bs = document.createElement("link");

bs.rel = "stylesheet";
bs.title = "mystyle"
bs.href = "images/audentio/gogreen/blue.css";

if (color == "green"){
    document.getElementsByTagName("head")[0].removeChild(rs);
    document.getElementsByTagName("head")[0].removeChild(bs);
    document.getElementsByTagName("head")[0].appendChild(gs);
}

else if (color == "blue"){
    document.getElementsByTagName("head")[0].removeChild(rs);
    document.getElementsByTagName("head")[0].removeChild(gs);
    document.getElementsByTagName("head")[0].appendChild(bs);
}

else (color == "red"){
    document.getElementsByTagName("head")[0].removeChild(gs);
    document.getElementsByTagName("head")[0].removeChild(bs);
    document.getElementsByTagName("head")[0].appendChild(rs);
}
}
else {
return: false;
}
});

嘿伙计们，我不擅长这些东西，它正在杀死我页面中的所有 jQuery（尽管出于我不会深入的原因，我不想使用 jQuery 来读取 cookie，只创建它）所以有人可以看到错误吗？

查找else (color == "red"){并替换为else if(color == "red"){

else (color == "red"){由于您刚刚忘记的此语句而导致的错误if

和改变

else {
    return: false;
}

到

else {
    return false;
}

remove : between return and false

并更改document.ready(function() {为$(document).ready(function() {或$(function() {

代替它

if (color == "green"){
    document.getElementsByTagName("head")[0].removeChild(rs);
    document.getElementsByTagName("head")[0].removeChild(bs);
    document.getElementsByTagName("head")[0].appendChild(gs);
}

else if (color == "blue"){
    document.getElementsByTagName("head")[0].removeChild(rs);
    document.getElementsByTagName("head")[0].removeChild(gs);
    document.getElementsByTagName("head")[0].appendChild(bs);
}

else if (color == "red"){
    document.getElementsByTagName("head")[0].removeChild(gs);
    document.getElementsByTagName("head")[0].removeChild(bs);
    document.getElementsByTagName("head")[0].appendChild(rs);
}

和

var head = document.getElementsByTagName("head")[0];
var links = head.getElementsByTagName("link");
for(var x=0; x<links.length ; x++)
{
   var href = links[x].href;
    if(href.indexOf('/green.css') >0 || href.indexOf('/red.css') >0|| href.indexOf('/blue.css') >0){
      head.removeChild(links[x]);
   }
}

if (color == "green"){
    head.appendChild(gs);
}
else if (color == "blue"){
    head.appendChild(bs);
}

else if (color == "red"){
   head.appendChild(rs);
}
