jQuery Get Element By Class

In this article we will show you the solution of jQuery get element by class, all elements that match the specified class of the elements are chosen by the element class selector.

Now move to the concept of jquery get element by class.

Step By Step Guide On jQuery Get Element By Class :-

Terminology

Components belonging to any class can be selected with the .class selector. An HTML element's class attribute is referred to by the term "class."

Many HTML elements can have a specific style assigned to them using the class property.

Never put a number at the beginning of a class attribute. Some browsers can have issues as a result.

Syntax

Here is how to utilise this selector in simple syntax:

$('.classid')

Parameters

This selection uses the following parameters, each of which is described here:

classidThis is the class ID that is present in the document, classid.

Returns

This selector returns an array containing all the elements it has found, just like every other jQuery selector does.

Example :-

$('.big') − $('.big') Chooses all the items that have the specified class ID big.

$('p.small') −All paragraphs with the specified class ID tiny are selected by the command $('p.small').

$('.big.small') − All components with the classes of ".big.small" and ".small" are selected by $('.big.small').

The jQuery method for obtaining components by class name.

1. Using the class selector in jQuery

The class selector ('.class') in jQuery can be used to select all items that have the specified class.

You should be aware that we can give the very same class to several document elements. Therefore, it is best to retrieve an element using its id.

2. The getElementsByClassName() function in JavaScript is used to obtain elements based on their class names:

It is possible to access items in pure JavaScript by using the native getElementsByClassName() JavaScript method, which returns a NodeList containing all elements with the specified class.

3. Using the querySelector() function in JavaScript

All document elements belonging to the same class are returned by the querySelectorAll() function.

It is possible to return the first element matching the given selector by using the querySelector() method.

4. Make use of the jQuery attr() Method.

To obtain the class name of the an element using jQuery, you only need to utilise the attr() method.

In what way may jQuery be used to determine the clicked element's class?

We employ this to determine the clicked element's class. className attribute. className property can be used to set or return class attribute value on an element.

A class of the an element can be changed using this attribute to the appropriate class.

Strategy:

To obtain a class name of something like the active div element in this case, we use the this.className attribute.

Five div elements with various class names have been put here. The class name of the clicked div element can then be obtained from the console using the jQuery this.className property.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
  $("p.intro").css("background-color", "grey");
});
</script>
</head>
<body>
<h1>Welcome to Talkerscode</h1>
<p class="intro">My name is Vaish.</p>
<p>I live in Delhi.</p>
<p class="intro">My name is Pragati.</p>
<p>I live in Mumbai.</p>
</body>
</html>
  1. With the aid of HTML & HEAD Tags, we begin our coding.
  2. After that, using script, we use the jquery library.
  3. Now, we launch the jQuery script.
  4. Next, the ready() function is used to run the jQuery code.
  5. After that, we make a class for getting elements and supply a value called an intro.
  6. In addition, we offer the colour of the background.
  7. The script then concludes.
  8. Following that, we begin our body and insert the heading using the H1 Tag.
  9. Following that, we created some statements using that class.
  10. Following that, we use different statements to highlight the differences.
  11. BODY & HTML Tags complete our code.

Conclusion :-

Consequently, we were able to understand the jQuery retrieve element by class notion.

Additionally, we can observe that its element class selector only chooses items that fall under the defined class of the elements.

I hope this article on jQuery get element by class helps you and the steps and method mentioned above are easy to follow and implement.
