telegram 狼人杀群的自动续命脚本，续满5人就不续了，并且会自动删除多余的续命消息（避免影响正常聊天），以及清理过多的历史记录（节约内存）

extend_300.js

var all_msgs = () => { return $(".im_history_message_wrap:visible"); };

var send = (cmd) => { $(".composer_rich_textarea").text(cmd); $(".im_submit").mousedown(); };

var ex_text = "/extend 299";
var ex_regexp = new RegExp(ex_text);
var own_regexp = /lccc/;
var del_regexp = new RegExp(ex_text + "|延長 299 秒|剩餘 \\d+ 秒|剩餘一分鐘");

(async function work() {
  var msgs = all_msgs();

  var flag = false;
  msgs.map((i, msg) => {
    if (flag) return ;
    if (ex_regexp.test(msg.innerText)) flag = true;
  });

  if (flag) {
    var del_count = 0;
    msgs.map((i, msg) => {
      if (del_regexp.test(msg.innerText)) {
        del_count += 1;
      };
    });

    var del_sel_count = 0;
    msgs.map(async (i, msg) => {

        $(".hasselect", msg).click();
        await new Promise(resolve => setTimeout(resolve, 70));

自动卷动滚动条至最下面，偶尔会需要这个

window.setInterval(() => { $(".im_history_scrollable_wrap").animate({ scrollTop: 99999 }, 'fast'); }, 3000);

自动 moha ...

window.setInterval(() => { send("+1s") }, 999 + Math.random() * 9999);
