有些時(shí)候我們需要根據(jù)某些條件來(lái)控制Web頁(yè)面中的HTML元素顯示還是隱藏，可以通過(guò)display或visibility來(lái)實(shí)現(xiàn)。通過(guò)下面的例子了解display和visibility的區(qū)別，簡(jiǎn)單的例子代碼如下：
代碼如下:
<html>
<head>
<title>HTML元素的顯示與隱藏控制</title>
<script type="text/javascript">
function showAndHidden1(){
var div1=document.getElementById("div1");
var div2=document.getElementById("div2");
if(div1.style.display=='block') div1.style.display='none';
else div1.style.display='block';
if(div2.style.display=='block') div2.style.display='none';
else div2.style.display='block';
}
function showAndHidden2(){
var div3=document.getElementById("div3");
var div4=document.getElementById("div4");
if(div3.style.visibility=='visible') div3.style.visibility='hidden';
else div3.style.visibility='visible';
if(div4.style.visibility=='visible') div4.style.visibility='hidden';
else div4.style.visibility='visible';
}
</script>
</head>
<body>
<div>display：元素的位置不被占用</div>
<div id="div1">DIV 1</div>
<div id="div2">DIV 2</div>
<input type="button" onclick="showAndHidden1();" value="DIV切換" />
<hr>
<div>visibility：元素的位置仍被占用</div>
<div id="div3">DIV 3</div>
<div id="div4">DIV 4</div>
<input type="button" onclick="showAndHidden2();" value="DIV切換" />
</body>
</html>
