jQuery Reference

Quick Reference

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

$('div').on('click', function() {
    alert('The element was clicked.');
});

Syntax

$(selector).on(event,childSelector,data,function,map)

Note

It is generally good practice to place your jQuery code/function inside the document load function so that the action takes place ONLY after the document has finished loading. This ensures that all of the page elements that you may be selecting are in place before running the code on them.

Parameters

ParameterDescription
eventSpecifies one or more event(s) or namespaces to attach to the selected elements; multiple event values are separated by space; must be a valid event (required)
childSelectorSpecifies that the event handler should only be attached to the specified child elements
dataSpecifies additional data to pass along to the function
functionSpecifies the function to run when the event occurs (required)
mapSpecifies an event map ({event:function, event:function, ...}) containing one or more event to attach to the selected elements, and functions to run when the events occur

jQuery Notes:

  • To use jQuery on your site, it must first be downloaded from the official jQuery site and linked to in your document <head>, or linked to via a CDN in your document <head>
  • It is generally good practice to place your jQuery code/function inside the document load function so that the action takes place ONLY after the document has finished loading
  • When using jQuery, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
