How jQuery Works

The jQuery syntax is made for selecting HTML elements and performing some action on the element, like $(selector).action() where $ sign is define/access, (selector) find HTML elements and action() fulfill on the element.


$(this).hide() – hides the current element.
$(“p”).hide() – hides all p elements.
$(“.test”).hide() – hides all elements with class=”test”.
$(“#test”).hide() – hides the element with id=”test”.

Example  with  using  jQuery.

<!DOCTYPE html>
<script src=""></script>

<p>click to disappear this text</p>
<p>click to disappear this text</p>
<p>click to disappear this text</p>


The good practice is wait for the document to be fully loaded before working with it and put the JavaScript code before the body of your document, in the head section.
