如果你有两点同样的id子,互联网的探索者就会混淆。 虽然这些物品在火ox中被罚款,但它们没有在互联网的探索者身上。 我改变了案文的样子,现在正在工作。
感谢 You guys.
var textArea = document.getElementById( textAreaId );
if (textArea.currentStyle.visibility === hidden || textArea.currentStyle.display === none )
{
/* code */
}
var myBox = document.getElementById("myBox");
if (myBox.currentStyle.display === "none" || myBox.currentStyle.visibility === "hidden") {
alert("Box is invisible");
}

<textarea id="myBox">Lorem ipsum doloet set amit</textarea>
你们是否尝试过?getBoundingClientRect()?
It will give all zero values if the element or a parent has display:none.
With visibility:hidden the element is there and then has a boudning rectangle.
<html>
<head>
<title>hidden</title>
</head>
<body>
<div style="display:none">
<form>
<textarea></textarea>
</form>
</div>
<script>
var rect = document.getElementsByTagName( TEXTAREA )[0].getBoundingClientRect();
alert(rect.right === 0 ? hidden : visible );
</script>
</body>
</html>
如果你们的 c们不敢展示:无;吗?
如果你想要隐瞒或显示,你就应该能够使用一些“金”:
$(document.body).css( "display", "none" );
或
$(myF或m.elements).hide()
因此。
