Set attribute without value

Closed 4 years ago.
I want to add an attribute on a div, something like this:
<div class='media' data-type-sticky></div>
Using jQuery, so i've tried this:
jQuery('.media').attr(data-type-sticky);
jQuery('.media').attr('data-type-sticky');


Just pass empty string to attr value.
$('.media').attr('data-type-sticky','');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='media'>Hello</div>

I used a query selector to get the div i want to append. But the created div doesn't want to append to anything other than the body. Is there a way i can make it specifically append under the div?

Look at this: https://www.w3schools.com/jsref/met_node_appendchild.asp
What you need to do is
parent.appendChild(thatDiv);

How may I know the number of same elements in Javascript? [duplicate]

How can I count the number of elements with same class?

I've got the following html :
<div class="same"></div>
<div class="same"></div>
And I want to print the number of div with the id "same" like this
<p><script>document.write(getElementbyId("#same").sum);</script></p>
And it would print : 2...
It actually doesn't work, I know I don't use the good Javascript function.

You'd use .length and .getElementsByClassName() like this:
<div class="same"></div>
<div class="same"></div>
<p><script>document.write(document.getElementsByClassName("same").length);</script></p>

Using :not() with attributes [duplicate]

How can I get the elements without a particular attribute by jQuery

I'm trying to use jquery to grab all select elements which do not have the "multiple" attribute set. I tried with the :not() but I can't get it quite right.
$(document).ready(function() {
$('select:not(multiple)').select2();
});

You forgot the attribute selector. What you're looking for there is "a <select> that is not a <multiple>"
$("select:not([multiple])").select2();

$('select:not([multiple])').select2();
or
$('select').not('[multiple]').select2();

Use document.documentElement.

var html = document.getElementsByTagName('html')[0];
