我上年都抄過呢段野
直接成段野貼入bookmark度
可以自己魔改block埋啲agent工，淨係搵公司自己po既job

javascript:(function(){ var i=0,x=document.getElementsByClassName('jobs-search-results-list')[0];function phase2(){document.querySelectorAll("li").forEach(function(e){e.id&&(e.innerHTML.match(/(Noir )|(Crossover)|(CareerAddict)|(eFinancialCareers)|(Understanding Recruitment)|(Oliver Bernard)|(Client Server )/))&&e.remove()}),setTimeout(function(){x.scrollTop=0},0)}!function e(){x.scroll(0,100*++i),i>40?phase2():setTimeout(e,0)}(); })();

(function() {
    'use strict';
    const out = /(Promoted)/g
    const callback = (records) => {
        document.querySelectorAll(".scaffold-layout__list-container .job-card-container").forEach(element => {
            element.textContent.match(out)?.length && element.remove();
        })
    }
    const observer = new MutationObserver(callback);
    observer.observe(document.body, { childList: true, subtree: true })
})();

每一次.remove() 會唔會trigger observer run一次callback

會

樓主可否講解下點apply段code既步驟
唔係好識
