There are a number of jQuery methods (actions) that can be used to manipulate your document. Here are some of the most common.

The following are merely quick examples of the method’s use. A complete list of methods (actions) can be found here along with more detailed descriptions of their intended use and syntax.

addClass() Method

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

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

attr() Method

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

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

click() Method

The click event occurs when an HTML element is clicked.

				
					// provide an alert when a div is clicked by the user
$('div').click(function() {
    alert('The element has been clicked.');
});
				
			

css() Method

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

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

html() Method

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>');
				
			

on() Method

The on() method attaches one or more event handlers to the selected elements and child elements.

				
					// when the user "clicks" on a div, provide an alert
$('div').on('click', function() {
    alert('The element was clicked.');
});
				
			

removeAttr() Method

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

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

removeClass() Method

The removeClass() method removes one or more class names from the selected elements.

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

text() Method

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');
				
			

val() Method

The val() method sets the value attribute of the selected elements.

				
					// sets the value for all form input fields that are text
$('input:text').val('Hello World');
