油猴脚本——极简化百度知道/经验

油猴脚本——优化百度知道、百度经验

鉴于个人工作需要，编写了此脚本。因为初学JavaScript，所以代码非常简陋、部分复写。请大神们不吝赐教，非常感谢！

我个人认为部分代码可以进行封装处理，以便复用。

2022-10-30迭代了一下，增加些代码。另一个账号的删掉了文章。

代码如下：
 

// ==UserScript==
// @name         极简化百度知道/经验（讯强定制版）
// @namespace    https://yuzhizhai.top
// @version      0.1.6
// @description  优化百度知道、百度经验页面，由流年_辣椒酱编写,代码参考1：https://blog.youkuaiyun.com/qq_38712932/article/details/85249112；代码参考2：https://blog.youkuaiyun.com/A13155283231/article/details/73613256

/*
//测试注入
(function(){
    if (document.domain != 'zhidao.baidu.com/' && document.domain != 'zhidao.baidu.com'){
    alert("百度经验-测试注入");}
    else{alert("百度知道-测试注入")};
})();
*/

//注意：部分代码需在HTML5.0环境下方可运行，可能会与其他优化百度页面的(油猴)脚本、广告移除扩展程序(adblocker)产生冲突！
//广告id列组，for循环以移除


//设置定时器，方便启动代码块
