jQuery removes Font Awesome Icon

Question

I am using Font Awesome and jQuery in an experiment, after an animation, the jQuery replaces a loading icon in a list by a check, and the text changes too. However, when I remove the jQuery replaceWith method, the icon stays:

HTML:

<ul class="fa-ul">
        <li><i class="fa-li fa fa-spinner fa-spin" id = "ToDo1"></i>Downloading</li>
        <li><i class="fa-li fa fa-square" id = "ToDo2"></i>text</li>
        <li><i class="fa-li fa fa-square" id = "ToDo3"></i>text</li>
        <li><i class="fa-li fa fa-square" id = "ToDo4"></i>text</li>
</ul>

jQuery:

setTimeout(function() {
    $("#ToDo1").removeClass("fa-spin fa-spinner");
    $("#ToDo1").addClass("fa-check-square");
    $("li:first").replaceWith("Download Complete");
    $("#ToDo2").addClass("fa-spin fa-spinner");
}, 2000);

Result:

before:

After jQuery replaceWith

What is the problem?

What exactly is it that you *want* to happen? `.replaceWith()` will replace the whole `

Change out this:

$("li:first").replaceWith("Download Complete");

With this:

$("li:first").html('<i class="fa-li fa fa-square" id = "ToDo1"></i>Download Complete');

In reality though, FlipFloop, you'll want to target your <i> element and text separately. Put your message into a span you can target independently of your markup replacement, like so:

<li><i class="fa-li fa fa-square" id = "ToDo2"></i><span>text</span></li>


$("li:first i").removeClass("fa-spin fa-spinner").addClass("fa-check-square");
$("li:first span").text("Download Complete");

Hope this helps.

The problem is that you replace the complete LI node instead of the inner text node inside it. To be able to address the text, wrap it in a SPAN like this.

<ul class="fa-ul">
    <li><i class="fa-li fa fa-spinner fa-spin" id = "ToDo1"></i><span class="download-status">Downloading</span></li>
    <li><i class="fa-li fa fa-square" id = "ToDo2"></i>text</li>
    <li><i class="fa-li fa fa-square" id = "ToDo3"></i>text</li>
    <li><i class="fa-li fa fa-square" id = "ToDo4"></i>text</li>
</ul>

Then you can change only the text you want like this.

setTimeout(function() {
    $("#ToDo1").removeClass("fa-spin fa-spinner");
    $("#ToDo1").addClass("fa-check-square");
    $("li:first > span").text("Download Complete");
    $("#ToDo2").addClass("fa-spin fa-spinner");
}, 2000);

Ah it's because you have i elements inside your li elements

So you'll need to make jQuery prepend an i element after changing the text

So .replaceWith and .text will get rid of the i

So you could do this

$('li:first').html('<i class="your font awesome class"></i>Download Complete');

Try the following snippet :

$(document).ready(function() {
  var time = 500;
  $('.load').each(function() {
    var temp = $(this);
    setTimeout(function() {
      temp.removeClass("fa-spin fa-spinner");
      temp.addClass("fa-check-square");
      temp.next("div").text("Download Complete");
      temp.next("i.load").addClass("fa-spin fa-spinner");
    }, 2000, temp);
  });
});

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="fa-ul">
  <li><i class="fa-li fa fa-spinner fa-spin load" id="ToDo1"></i>
    <div>Downloading</div>
  </li>
  <li><i class="fa-li fa fa-square load" id="ToDo2"></i>text</li>
  <li><i class="fa-li fa fa-square load" id="ToDo3"></i>text</li>
  <li><i class="fa-li fa fa-square load" id="ToDo4"></i>text</li>
</ul>

Wrap the text in a span and then change it since replaceWith will replace the complete contents of the li including the icon.
