HTML DOM visibility 属性
定义和用法
visibility 属性设置元素是否可见。
语法：
Object.style.visibility=visible|hidden|collapse
可能的值
| 值 | 描述 |
|---|---|
| visible | 默认。元素框是可见的。 |
| hidden | 元素框不可见，但仍然影响布局。 |
| collapse | 当在表格元素中使用时，此值可删除一行或一列，但是它不会影响表格的布局。被行或列占据的空间会留给其他内容使用。如果此值被用在其他的元素上，会呈现为 "hidden"。 |
实例
下面的例子隐藏一段文本：
<html>
<head>
<script type="text/javascript">
function changeVisibility()
{
document.getElementById("p1").style.visibility="hidden";
}
</script>
