toggle show/hide div with button?


Hopefully this is an easy question. I have a div that I want to toggle hidden/shown with a button

<div id="newpost">

Look at jQuery Toggle

HTML:

<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>

jQuery:

jQuery(document).ready(function(){
    jQuery('#hideshow').live('click', function(event) {        
         jQuery('#content').toggle('show');
    });
});

For versions of jQuery 1.7 and newer use

jQuery(document).ready(function(){
    jQuery('#hideshow').on('click', function(event) {        
        jQuery('#content').toggle('show');
    });
});

For reference, kindly check this demo


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();
});

HTML5 - Toggle using <summary> and <details>

(unsupported on IE and Opera Mini)

<details>
  <summary>TOGGLE</summary>
  <p>Some content...</p>
</details>

HTML - Toggle using checkbox

[id^=toggle],
[id^=toggle] + *{
  display:none;
}
[id^=toggle]:checked + *{
  display:block;
}
<label for="toggle-1">TOGGLE</label>

<input id="toggle-1" type="checkbox">
<div>Some content...</div>

HTML - Switch using radio

[id^=switch],
[id^=switch] + *{
  display:none;
}
[id^=switch]:checked + *{
  display:block;
}
<label for="switch-1">SHOW 1</label>
<label for="switch-2">SHOW 2</label>

<input id="switch-1" type="radio" name="tog">
<div>1 Merol Muspi...</div>

<input id="switch-2" type="radio" name="tog">
<div>2 Lorem Ipsum...</div>

CSS - Switch using :target

(just to make sure you have it in your arsenal)

[id^=switch] + *{
  display:none;
}
[id^=switch]:target + *{
  display:block;
}
<a href="#switch1">SHOW 1</a>
<a href="#switch2">SHOW 2</a>

<i id="switch1"></i>
<div>1 Merol Muspi ...</div>

<i id="switch2"></i>
<div>2 Lorem Ipsum...</div>


Animating class transition

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>


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>


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>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#hideshow').click(function(){
    $('#content').toggle('show');
  });
});
</script>

And the html

<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>

You could use the following:

mydiv.style.display === 'block' = (mydiv.style.display === 'block' ? 'none' : 'block');
