如果有變量 get (SID) 則需要刪除現有的類 (forceview)網址示例：https ://example.com/ ? SID = eqwe7q7e6868我正在獲取變量并嘗試插入顯示（無）。function sid() {  // Gets a url that includes the `?` character  var url = "somedomain.net?search";  if (url.indexOf("?") > 0) {    // Selects elements with the "forceview" class    const forceviews = document.getElementsByClassName("forceview");    // Loops through these elements and removes them from display    for (let forceview of forceviews){      forceview.style.display = "none";    }    console.log("all `.forceview` elements have been hidden");  }}sid();span.old-price.sly-old-price.no-display.forceview {    display: inline !important;}<span class="old-price sly-old-price no-display forceview">  <span class="price-container price-final_price tax weee">    <span class="price-label">Pre?o Normal    </span>    <span id="old-price-1263-final_price" data-price-amount="19.9" data-price-type="oldPrice" class="price-wrapper ">      <span class="price">R$19,90</span>    </span>  </span></span>
