4. Data Attribute

HTML provides custom data attributes that allow adding additional information related to the content in HTML tags. These attributes are not specific to HTML5 and can be used on all HTML elements. The data-* attribute enables the creation of custom data attributes that can store private data for the page or application.

In order to customize, one divides the data into two parts:

  • Attribute Name: It should have at least one character long and should not have any capital letters. This name can also be prefixed by using “data-“.
  • Attribute Value: Any string value can be associated with the attribute.

The syntax for a data attribute is as follows:

<li data-book-author="Rabindra Nath Tagore"> Gitanjali </li>

5. DOM Attribute Property

To retrieve the NamedNodeMap objects, one can use the attribute properties in the HTML DOM. This will return a group of node attributes. The NamedNodeMap represents a collection of attribute objects, which can be accessed by their index number, starting at 0. To use this, the user can access the node’s attributes using the syntax node.attributes.

The value returned is a NamedNodeMap object that contains all the attributes in the collection of nodes. However, if someone is using Internet Explorer 8 or an earlier version, the attributes property may return all possible attributes for any element, resulting in more values than expected.

Example:

Code:

<!DOCTYPE html>
<html>
<head>
<title>
HTML DOM attributes Property
</title>
</head>
<body>
<h2>
HTML DOM attributes Property
</h2>
<button id = "CBA" onclick = "myeduCBA()">
Click Here!
</button>
<br><br>
<span>
Button element attributes:
</span>
<span id="sudo"></span>
<script>
function myeduCBA() {
// It returns the number of nodes
var cba = document.getElementById("CBA").attributes.length;
// Display the number of nodes
document.getElementById("sudo").innerHTML = cba;
}
</script>
</body>
</html>
The output for above program will be
Button element attributes: 2

6. Global Attributes

HTML also provides global attributes that can work with any HTML element:

  • Accesskey: Specifies a shortcut key to activate or focus on any element.
  • Translate: Specifies whether the content of the element is to be translated or not.
  • Class: One or more class names for an element are specified.
  • Title: Specifies extra information about an element.
  • Contenteditable: This attribute can be used to specify whether the content is editable or not.
  • Tabindex: Specifies the tabbing order of an element.
  • Dir: Specifies the text direction for any content of an element.
  • Spellcheck: Users can explicitly specify if they want to have the spelling and grammar checked or not.
  • Draggable: Specifies if an element should be draggable or not.
  • Dropzone: Specifies whether the dragged data is copied, moved, or linked when dropped.

7. Event Attributes

HTML has the ability to trigger actions when some events take place.

  • Onload: Fires after the page has finished loading.
  • Onmessage: A script that runs when the message is triggered.
  • Onstorage: A script that runs when a web storage area is updated.
  • Onerror: The script runs when an error occurs.
  • Onpagehide: The script can be used when the user navigates away from a page.
