求大佬解释一段js代码的含义。

代码如下：

window["\x61\x6c\x65\x72\x74"]("\u6b22\u8fce\u4f7f\u7528\u65fa\u9500\u738b\u9ed1\u79d1\u6280\u5de5\u5177\u5305 \x77\x77\x77\x2e\x77\x78\x77\x65\x72\x70\x2e\x63\x6f\x6d \u5173\u6ce8\x53\x68\x6f\x70\x65\x65\u7c89\u4e1d\u5f00\u59cb\u5566");setInterval(function () {var t$hcAFO1 = $(window["\x64\x6f\x63\x75\x6d\x65\x6e\x74"])['\x68\x65\x69\x67\x68\x74']() - $(window)['\x68\x65\x69\x67\x68\x74']();$(window["\x64\x6f\x63\x75\x6d\x65\x6e\x74"])['\x73\x63\x72\x6f\x6c\x6c\x54\x6f\x70'](t$hcAFO1);$("\x2e\x62\x74\x6e\x2d\x66\x6f\x6c\x6c\x6f\x77\x3a\x6e\x6f\x74\x28\x2e\x61\x63\x74\x69\x76\x65\x29")['\x65\x61\x63\x68'](function () {if ($(this)['\x70\x61\x72\x65\x6e\x74\x73']("\x6c\x69")['\x66\x69\x6e\x64']("\x2e\x64\x6f\x77\x6e \x61")['\x61\x74\x74\x72']("\x75\x73\x65\x72\x6e\x61\x6d\x65") == null || ($(this)['\x70\x61\x72\x65\x6e\x74\x73']("\x6c\x69")['\x66\x69\x6e\x64']("\x2e\x64\x6f\x77\x6e \x61")['\x61\x74\x74\x72']("\x75\x73\x65\x72\x6e\x61\x6d\x65")['\x69\x6e\x64\x65\x78\x4f\x66']("\x2e\x6d\x79") < 0 && $(this)['\x70\x61\x72\x65\x6e\x74\x73']("\x6c\x69")['\x66\x69\x6e\x64']("\x2e\x64\x6f\x77\x6e \x61")['\x61\x74\x74\x72']("\x75\x73\x65\x72\x6e\x61\x6d\x65")['\x69\x6e\x64\x65\x78\x4f\x66']("\x2e\x74\x77") < 0)) {$(this)['\x74\x72\x69\x67\x67\x65\x72']("\x74\x61\x70");}})}, 6000)

弱弱的再问一下，这个能不能在基础上进行修改使用

 这是这段代码的含义；

就只是unicode编码的中文字符串而已。

这代码被编码处理过的，你知道原码吗

代码解码之后是这样的

window["alert"]("欢迎使用旺销王黑科技工具包 www.wxwerp.com 关注Shopee粉丝开始啦");
setInterval(function() {
	var t$hcAFO1 = $(window["document"])['height']() - $(window)['height']();
	$(window["document"])['scrollTop'](t$hcAFO1);
	$(".btn-follow:not(.active)")['each'](function() {
		if ($(this)['parents']("li")['find'](".down a")['attr']("username") == null || ($(this)['parents']("li")['find'](".down a")['attr']("username")['indexOf'](".my") < 0 && $(this)['parents']("li")['find'](".down a")['attr']("username")['indexOf'](".tw") < 0)) {
			$(this)['trigger']("tap");
		}
	})
}, 6000)

把
$(".btn-follow:not(.active)")['each'](function() {
改成
$(".btn-follow.active")['each'](function() {
应该就是取关用户了
