纯JavaScript：
var button = document.getElementById('button'); // Assumes element with id='button'
button.onclick = function() {
var div = document.getElementById('newpost');
if (div.style.display !== 'none') {
div.style.display = 'none';
}
else {
div.style.display = 'block';
}
};
<强>的jQuery ：
$("#button").click(function() {
// assumes element with id='button'
$("#newpost").toggle();
});

<强> HTML：
<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>
<强> jQuery的：
jQuery(document).ready(function(){
jQuery('#hideshow').live('click', function(event) {
jQuery('#content').toggle('show');
});
});
对于jQuery 1.7和更新版本的使用
jQuery(document).ready(function(){
jQuery('#hideshow').on('click', function(event) {
jQuery('#content').toggle('show');
});
});

Element.styleMDN
var toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function() {
content.style.display = (content.dataset.toggled ^= 1) ? "block" : "none";
});#content{
display:none;
}<button id="toggle">TOGGLE</button>
<div id="content">Some content...</div>

<div>2 Lorem Ipsum...</div>
如果您选择一种JS / jQuery方式来实际切换className，您可以随时为元素添加动画过渡，这是一个基本示例：
var toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function(){
content.classList.toggle("appear");
}, false);#content{
/* DON'T USE DISPLAY NONE/BLOCK! Instead: */
background: #cf5;
padding: 10px;
position: absolute;
visibility: hidden;
opacity: 0;
transition: 0.6s;
-webkit-transition: 0.6s;
transform: translateX(-100%);
-webkit-transform: translateX(-100%);
}
#content.appear{
visibility: visible;
opacity: 1;
transform: translateX(0);
-webkit-transform: translateX(0);
}<button id="toggle">TOGGLE</button>
<div id="content">Some Togglable content...</div>

这是一种简单的Javascript切换方式：
<script>
var toggle = function() {
var mydiv = document.getElementById('newpost');
if (mydiv.style.display === 'block' || mydiv.style.display === '')
mydiv.style.display = 'none';
else
mydiv.style.display = 'block'
}
</script>
<div id="newpost">asdf</div>
<input type="button" value="btn" onclick="toggle();">

这就是我使用类隐藏和显示内容的方法。将班级更改为空将更改显示为阻止，将班级更改为＆＃39; a＆＃39;将显示为无。
<!DOCTYPE html>
<html>
<head>
<style>
body {
background-color:#777777;
}
block1{
display:block; background-color:black; color:white; padding:20px; margin:20px;
}
block1.a{
display:none; background-color:black; color:white; padding:20px; margin:20px;
}
</style>
</head>
<body>
<button onclick="document.getElementById('ID').setAttribute('class', '');">Open</button>
<button onclick="document.getElementById('ID').setAttribute('class', 'a');">Close</button>
<block1 id="ID" class="a">
<p>Testing</p>
</block1>

您可以使用以下内容：
