我想使用<div>标记隐藏表格的某些字段（参见下文）。我的问题是调用可见性的代码被调用，但之后没有任何东西被隐藏。
我的代码到目前为止：
function checkType() {
let typeElement = document.getElementById('storyboardType');
let type = parseInt(typeElement.selectedIndex);
if (type === TYPE_NONE || type === TYPE_GAME) {
document.getElementsByClassName('storyboardUrlDiv').style.visibility = 'hidden';
document.getElementById('storyboardSpeakerDiv').style.visibility = 'hidden';
document.getElementById('storyboardAthmosphereDiv').style.visibility = 'hidden';
} else if (type === TYPE_URL) {
document.getElementById('storyboardUrlDiv').style.visibility = 'visible';
document.getElementById('storyboardSpeakerDiv').style.visibility = 'hidden';
document.getElementById('storyboardAthmosphereDiv').style.visibility = 'hidden';
} else if (type === TYPE_SOUND || type === TYPE_VIDEO) {
document.getElementById('storyboardUrlDiv').style.visibility = 'visible';
document.getElementById('storyboardSpeakerDiv').style.visibility = 'visible';
document.getElementById('storyboardAthmosphereDiv').style.visibility = 'visible';
}
}<table>

此处使用<div>标记是否有问题？
答案 0 :(得分：2)
您的HTML无效。使用a validator。
div不能是<tr>的子元素，错误恢复往往会将这些div移到表后面（将<td>元素留在后面）。
因此，细胞不再是div的子元素，所以当你隐藏div时，没有明显的效果。
改为编写有效的HTML。
如果要定位一行中的某些（但不是全部）单元格，则必须单独定位它们。没有标记可用于对它们进行分组。
