jQuery contains a multitude of DOM-related methods that make it easy to access and manipulate HTML elements and attributes.

The following are some quick examples of the methods used to manipulate page elements. A complete list of DOM-related methods can be found here along with more detailed descriptions of their intended use and syntax.

The addClass() method adds one or more class names to the selected elements.

// add a .content class to all paragraphs
$('p').addClass('content');

The append() method inserts specified content (HTML tags, jQuery objects, DOM elements) at the end of the selected elements.

// add content before every paragraph's closing tag
$('p').append('<p>Hello World</p>');

The attr() method sets attributes and values of the selected elements.

// adds and sets the width for images
$('img').attr('width', '80');

The css() method sets one or more style properties for the selected elements.

// set color property for all paragraphs
$('p').css('color', 'red');

The html() method sets the content (innerHTML) of the selected elements.

// sets the content of all paragraphs to say Hello World!
$('p').html('<strong>Hello world!</strong>');

The prepend() method inserts specified content (HTML tags, jQuery objects, DOM elements) at the beginning of the selected elements.

// add content just after every paragraph's opening tag
$('p').prepend('<p>Hello World</p>');

The removeAttr() method removes one or more attributes from the selected elements.

// removes the color attribute from all paragraph elements
$('p').removeAttr('color');

The removeClass() method removes one or more class names from the selected elements. If no parameter is specified, this method will remove ALL class names from the selected elements.

// removes the .section class from all paragraph elements
$('p').removeClass('section');

The text() method sets the text content of the selected elements, overwriting the content of ALL matched elements. This only replaces the text inside the element and does NOT remove the elements tags or attributes.

// replace the text within all paragraph elements
$('p').text('Hello world');
