I have a button and a div, i want to append this div once every time i click on the button, but i have a problem, the HTML code for this div is very large and i don't want that, so my question is there another method to append this div without putting the whole code in my js code? and another problem i want to append the div once only on each click but it appends it multiple times, Here is an example of what I'm talking about, i replaced my large HTML code with a small one, so here is my code:

$(".appendbtn").click(function () {
   $(".appendme").append('<div class="appendme">The div that should be appended</div>');
});

<script
  src=".2.3.min.js"
  integrity="sha256-a23g1Nt4dtEYOj7bR+vTu7+T8VP13humZFBJNIYoEJo="
  crossorigin="anonymous"></script>
<div class="appendme">The div that should be appended</div>
<button class="appendbtn" type="button">Click to append</button>

• You called the object you insert as the object to insert – Gianfrancesco Aurecchia Commented Jul 7, 2017 at 13:41
• 1 For the first part of question the answer could be: jQuery.get() the html from your server. For the second question it's enough to add :first selector: $(".appendme:first").append( – gaetanoM Commented Jul 7, 2017 at 13:47

Lots of answers here point out your naming error ('appendme' used for the container and the item being appended) but your issue is that you have a large string that you want to append. The object that you want to append could be placed within a script tag:

<script type="text/html" id="appendTemplate">
    <div>The div that should be appended</div>
</script>

And now your append code will be:

$(".appendbtn").click(function () {
    var template = $('#appendTemplate").html();
    $(".appendme").append(template);
});

When the button is clicked, the html content of the script tag is read into the variable 'template' which you then append to your target element.

Easy to fix by adding a container.

This should do the trick:

$(".appendbtn").click(function () {
   $("#divcontainer").append('<div class="appendme">The div that should be appended</div>');
});

<script
  src="https://code.jquery./jquery-2.2.3.min.js"
  integrity="sha256-a23g1Nt4dtEYOj7bR+vTu7+T8VP13humZFBJNIYoEJo="
  crossorigin="anonymous"></script>
<div id="divcontainer">
  <div class="appendme">The div that should be appended</div>
</div>
<button class="appendbtn" type="button">Click to append</button>

The issue is the <div> you append to .appendme also has a class of .appendme. So when you click the button, the new <div> is being appended to every other new <div class="appendme"> that has been appended.

To fix this, remove the class or rename the class of the new <div> being appended.

$(".appendbtn").click(function () {
   $(".appendme").append('<div>The div that should be appended</div>');
});

<script
  src="https://code.jquery./jquery-2.2.3.min.js"
  integrity="sha256-a23g1Nt4dtEYOj7bR+vTu7+T8VP13humZFBJNIYoEJo="
  crossorigin="anonymous"></script>
<div class="appendme">The div that should be appended</div>
<button class="appendbtn" type="button">Click to append</button>

I would do like that :

$(".appendbtn").click(function () {
   $(".appendme:last").append(getHtml());
});

function getHtml(){
  return '<div class="appendme">The div that should be appended</div>';
}

<script
  src="https://code.jquery./jquery-2.2.3.min.js"
  integrity="sha256-a23g1Nt4dtEYOj7bR+vTu7+T8VP13humZFBJNIYoEJo="
  crossorigin="anonymous"></script>
<div class="appendme">The div that should be appended</div>
<button class="appendbtn" type="button">Click to append</button>
