Question

I’m learning jQuery and had a question about a method call on an HTML element. In this case it’s a <div> tag.

The jQuery call goes like this:

<script type="text/javascript">

$(function(){
 $('.someClass').myMethod({
  value1: 'sometext',
  value2: 'someothertext'
  });
 });

</script>

The <div> tag has a CSS class of ‘someClass’, as you can see below:

<div class="someClass" style="display: none;">
<div id="my-content">
<img id="enter" alt="Logo" src="images/logo.png">
</div>
</div>

My question is, what’s happening with that method call in jQuery? Is it looping over all elements contained within the <div class='someClass'/> and calling myMethod on all of them?

Answer 1

It completely depends on the plugin implementation.

$('.someClass') will select all the elements with calss .someClass now its the plugin which will use this set and apply its logic on the set of matched elements or just a single element.
