jQuery Selectors Manipulate
jQuery selectors allow you to select and manipulate HTML element(s).
jQuery selectors are used to "find" (or select) HTML elements based on their name, id, classes, types, attributes, values of attributes and much more. It's based on the existing CSS Selectors, and in addition, it has some own custom selectors.
All selectors in jQuery start with the dollar sign and parentheses: $().
The element Selector
The jQuery element selector selects elements based on the element name.
You can select all <p>
elements on a page like this:
$("p")
Example
When a user clicks on a button, all <p>
elements will be hidden:
Example
$(document).ready(function(){
$("button").click(function(){
$("p").hide();
});
});

The #id Selector
The jQuery #id
selector uses the id attribute of an HTML tag to find the specific element.
An id should be unique within a page, so you should use the #id selector when you want to find a single, unique element.
To find an element with a specific id, write a hash character, followed by the id of the HTML element:
$("#test")
Example
When a user clicks on a button, the element with id="test" will be hidden:
Example
$(document).ready(function(){
$("button").click(function(){
$("#test").hide();
});
});

The .class Selector
The jQuery .class
selector finds elements with a specific class.
To find elements with a specific class, write a period character, followed by the name of the class:
$(".test")
Example
When a user clicks on a button, the elements with class="test" will be hidden:
Example
$(document).ready(function(){
$("button").click(function(){
$(".test").hide();
});
});

Functions In a Separate File
If your website contains a lot of pages, and you want your jQuery functions to be easy to maintain, you can put your jQuery functions in a separate .js file.
When we demonstrate jQuery in this tutorial, the functions are added directly into the <head>
section. However, sometimes it is preferable to place them in a separate file, like this (use
the src attribute to refer
to the .js file):
Example
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
<script src="my_jquery_functions.js"></script>
</head>
