This article shares with you a relatively simple JS code for controlling hidden display. Friends in need can take a look.

It is a relatively simple implementation. style.display is to control the hiding of the layer. Or the displayed attribute.

<html>
<body>
<script>
function show(){
document.getElementById("p").style.display="";
//alert(document.getElementById("p").style.display)
}
function hidden(){
document.get
ElementById("p").style.display="none";
//alert(document.getElementById("p").style.display)
}
</script>
<BODY>
<input name="name" type="button" onClick="show();" value="显示">
<p id="p" style="display: none" onMouseout="hidden();">
show it
</p>
</BODY>
</HTML>

p'svisibility can control the display and hiding of p, but after hiding, the page will appear blank

style="visibility: none;"
document.getElementById("typep1").style.visibility="hidden";//隐藏
document.getElementById("typep1").style.visibility="visible";//显示


By setting the display attribute, you can release the occupied page space after p is hidden , as follows

style="display: none;"
document.getElementById("typep1").style.display="none";//隐藏
document.getElementById("typep1").style.display="";//显示

If you use p.style.display="none" to hide it, things in p will sleep and the events inside will not respond.
