W3.CSS 導航選項卡 - 顯示 2 id

Question

我正在使用 W3.CSS 導航選項卡，但我遇到了問題。 我有 2 個 id，我想在人們時顯示 2 個 id，例如，單擊 Tab“London”然后顯示 2 個 id。 在 W3.CSS Navigation Tabs 代碼中，我只能同時顯示 1 個 id，但我不知道如何再添加 1 個 id 來顯示

一個簡單的解決方案是將多個城市名稱作為數組而不是單個城市名稱傳遞給openCity函數。

在以下示例中，當您單擊選項卡London時，將顯示 ID 為London和Paris的 2 個選項卡的內容。

 function openCity(evt, cityNames) { let i, x, tablinks; x = document.getElementsByClassName("city"); for (i = 0; i < x.length; i++) { x[i].style.display = "none"; } tablinks = document.getElementsByClassName("tablink"); for (i = 0; i < x.length; i++) { tablinks[i].className = tablinks[i].className.replace(" w3-border-red", ""); } cityNames.map(function(city) { document.getElementById(city).style.display = "block"; }); evt.currentTarget.firstElementChild.className += " w3-border-red"; }
