我正在处理这部分代码:
<div class="tabs-buttons-container">
<button class="tabs-button" onclick="openTabs(event, 'test11', 'red')">Tab 1</button>
<button class="tabs-button" onclick="openTabs(event, 'test12')">Tab 2</button>
<button class="tabs-button" onclick="openTabs(event, 'test13')">Tab 3</button>
<span class="test"></span>
<span class="red"></span>
<span class="white"></span>
</div>
const openTabs = (event, tab, test) => {
let i, tabContent, tabButton;
tabContent = document.getElementsByClassName("tabs-content")
for (i = 0; i < tabContent.length; i++) {
tabContent[i].style.display = "none";
}
document.getElementById(tab).style.display = "block";
document.getElementsByClassName(test).style.display = "block";
}
我当前的目标是将“red”类传递到函数中并更改 span 元素的显示。当我使用 ID 时,它工作正常,但当我想传递类时,结果为 null。是否可以在 JS 函数中动态传递类名?
