html - Remove a DIV with a delay Javascript - Stack Overflow|江阴雨辰互联

this is my first question so forgive me if I don't apply the correct etiquette.

I have a javascript function that hides a div with a fade.

function fadeOut(cloudChatHide)
{
    "use strict";
    cloudChatHide.onclick = function()
        { 
            if(cloudChatHide.className)
                {
                cloudChatHide.className = '';
                } 
            else 
                {               
                cloudChatHide.className = 'fadeout';
                RemoveCloudChat();
                }
        };
}

However this code doesn't remove the DIV which is the RemoveCloudChat Function. Which looks like this:-

function RemoveCloudChat()
{
    "use strict";
    cloudChatHide.remove();
    cloudChatHide.className ='fadeout';
}

What I really want to do is fade the div automatically after a few seconds and then REMOVE it.

The reason I need to REMOVE the div from the window is that its an overlaid div and I need to access the content underneath the 'cloudChatHide' div.

Any help / instruction wouild be gratefully received as I am not the greatest Javascript developer.

Thanks.

You can use CSS transitions to smoothly fade out the element and listen for the transitionend event to remove the element when the transition has finished.

See this jsFiddle.

The transition is defined with this CSS:

div {
  opacity: 1;
  transition: opacity 1s;
}

div.fade-out {
  opacity: 0;
}

As soon as you add the fade-out class to a div it will smoothly reduce its opacity over a period of 1 second. This can be done with the following JavaScript, no jQuery required:

function fadeOutAndRemove(element) {
    element.classList.add('fade-out');
    element.addEventListener('transitionend', function () {
      element.parentNode.removeChild(element);
    });
}

If you want to start the fadeout transition automatically after a fixed delay you could call fadeOutAndRemove after a timeout

window.setTimeout(fadeOutAndRemove.bind(this, elementToHide), 3000)

or add a delay to the transition

transition: opacity 1s 3s;

and initalise the element with the fade-out class

<div class="fade-out"></div>

If you could use JQuery, it will really simple, see following:

<html>
<head>
  <meta charset="utf-8">
  <script src="https://code.jquery./jquery.min.js"></script>
</head>
<body>
  <div class="fadeout">I'LL DISAPPEAR IN 3 SECONDS</div>
</body>
  <script>
    function fadeOut()
    {
        $(".fadeout").fadeToggle(500, "swing",function(){
                  this.remove();
                });
    }

    var delay = 3000; //3 seconds
    setTimeout(fadeOut, delay);
  </script>
</html>

When the fade action is pleted the div will be removed. I hope it helps you, bye.

Brilliant result from Alessandro Maglioccola

<html>
<head>
  <meta charset="utf-8">
  <script src="https://code.jquery./jquery.min.js"></script>
</head>
<body>
  <div class="fadeout">I'LL DISAPPEAR IN 3 SECONDS</div>
</body>
  <script>
    function fadeOut()
    {
        $(".fadeout").fadeToggle(500, "swing",function(){
                  this.remove();
                });
    }

    var delay = 3000; //3 seconds
    setTimeout(fadeOut, delay);
  </script>
</html>

Here's a way to do it without Jquery. I'm setting the opacity to 0 waiting 300ms using a setTimeout then do the reverse if it's already hidden.

hideMe = function(selector, self) {
  var elem = document.querySelector(selector);
  if (self.innerHTML == "Hide") {
    elem.classList.add("fade");
    setTimeout(function() {
      elem.classList.add("hidden");
      self.innerHTML = "Show";
    }, 300)
  } else {
    elem.classList.remove("hidden");
    setTimeout(function() {
      elem.classList.remove("fade");
      self.innerHTML = "Hide";
    }, 300)
  }
}

body {
  margin: 0;
}

.header {
  height: 100px;
  width: 100%;
  background: steelblue;
}

#vanish {
  transition: all 300ms cubic-bezier(.25, .8, .25, 1);
}

.redsquare {
  width: 100%;
  height: 225px;
  background: tomato;
  opacity: 1;
}

.hidden {
  height: 0px;
  width: 0px;
}

.fade {
  opacity: 0;
}

button {
  width: 100%;
  height: 25px;
  border: 0px;
  outline: none;
  cursor: pointer;
}

<div class="header"></div>
<button onclick='hideMe("#vanish",this)'>Hide</button>
<div id="vanish" class="redsquare"></div>
<div class="header"></div>
