Question

我希望在网页正文中查找/搜索匹配的正则表达式（在此示例中为PO123456）。如果发现我想要一个警告说它被找到并且脚本停止运行。如果未找到RegEx匹配，我希望重复重新加载页面，直到找到匹配项。然后我会将此脚本粘贴到TamperMonkey中，以便在当前要求我像实验动物一样重复刷新的页面上使用。

以下不起作用，但......

// ==UserScript==
// @name         Reload Page If RegEx Match Not Found
// @namespace   
// @version      0.1
// @description  Reloads Page Until RegEx Match Found
// @author       TJ
// @match        https://system.fakepage.com/someotherpage
// @grant        none
// ==/UserScript==

$(document).ready(function()
{
    var regex = /^PO\d{6}g/;
    var PO = str.match(regex);

    if($('body:contains("' + PO + '")').length > 0)
    {
    alert("Found: " + PO);
    }
    else
    {
        location.reload();
    }
});

请帮助我把这个剧本弄清楚，帮助聪明的pavlovian控制系统！（经过测试，我想废除警报。）
