Hopefully this is an easy question. I have a div
that I want to toggle hidden/shown with a button
This is how I hide and show content using a class. changing the class to nothing will change the display to block, changing the class to 'a' will show the display as none.
<!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>
</body>
</html>
You could use the following:
mydiv.style.display === 'block' = (mydiv.style.display === 'block' ? 'none' : 'block');
Pure 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';
}
};

jQuery:
$("#button").click(function() {
// assumes element with id='button'
$("#newpost").toggle();
});

Here's a plain Javascript way of doing toggle:
<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();">
Try with opacity
div { transition: all 0.4s ease }
.hide { opacity: 0; }
<input onclick="newpost.classList.toggle('hide')" type="button" value="toggle">
<div id="newpost">Hello</div>
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>

If you pick one of JS / jQuery way to actually toggle a className
, you can always add animated transitions to your element, here's a basic example:
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>
