我有两个 div,一个是隐藏的,另一个是可见的。我正在使用CSSdisplay:none;
首先隐藏并使用style.display="block";
当我刷新页面时,它在地址栏中给出相同的 div 名称,但 div 被隐藏。
我只是希望 div 在刷新或提交 div 内的表单后保持阻塞状态
<html>
<head>
<meta charset="utf-8">
<title>Sample</title>
<style>
#content {
flex:8;
display:flex;
flex-direction:row;
justify-content:space-between;
flex-basis:100%;
padding:0 10px 0x 10px;
text-align:center;
}
#leftnav {
flex:1;
padding-top:20px;
}
#midcontent {
flex:9;
text-align:center;
padding-top:20px;
display:block;
}
#leftnav ul {
display: block;
margin: 0px;
padding: 0px;
list-style-type: none;
}
#m1,#m2,#m3 {
flex:9;
text-align:center;
padding-top:20px;
display:none;
}
</style>
</head>
<body>
<div id="content">
<div id="leftnav" align="center">
<ul>
<li><a href="#m1" onClick="div1()">Page m1</a></li>
<li><a href="#m2" onClick="div2()">Page m2</a></li>
<li><a href="#m3" onClick="div3()">Page m3</a></li>
</ul>
</div>
<div id="midcontent" align="center">
<p>Home Page</p>
</div>
<div id="m1" align="center">
<p>Div m1</p>
</div>
<div id="m2" align="center">
<p>Div m2</p>
</div>
<div id="m3" align="center">
<p>Div m3</p>
</div>
</div>
<script type="text/javascript">
var d=document.getElementById('midcontent');
var d1=document.getElementById('m1');
var d2=document.getElementById('m2');
var d3=document.getElementById('m3');
function div1() {
if(d.style.display === "block") {
d.style.display = "none";
d1.style.display = "block";
} else {
d.style.display = "none";
d1.style.display = "block";
d2.style.display = "none";
d3.style.display = "none";
}
}
function div2() {
if(d.style.display === "block") {
d.style.display = "none";
d2.style.display = "block";
} else {
d.style.display = "none";
d1.style.display = "none";
d2.style.display = "block";
d3.style.display = "none";
}
}
function div3() {
if(d.style.display === "block") {
d.style.display = "none";
d3.style.display = "block";
} else {
d.style.display = "none";
d1.style.display = "none";
d2.style.display = "none";
d3.style.display = "block";
}
}
</script>
</body>
</html>
change:
function div1() {
var d=document.getElementById('midcontent');
var d1=document.getElementById('m1');
if(d.style.display === "block") {
d.style.display = "none";
d1.style.display = "block";
} else {
d.style.display = "none";
d1.style.display = "block";
}
}
to:
function toggleDiv() {
document.getElementById('midcontent').style.display = "none";
document.getElementById('m1').style.display = "block";
}
“我只是希望 div 在刷新后保持阻塞”在 html 中调用页面加载函数以使其在刷新页面后执行:
<body onLoad="toggleDiv()">
<!-- Your html content -->
</body>
或者你也可以用js来做:
document.addEventListener("DOMContentLoaded", function(event) {
toggleDiv()
});
如果您想要更深入的持久性和/或变量更改,请提供有关如何以及为什么要执行此操作的附加信息!
