jQuery Reference

Quick Reference

The offset() method sets the offset coordinates for ALL matched elements the selected elements, relative to the document.

$('p').offset()
// set the offset
$('p').offset({top:50, left:50});

Syntax

Set the offset:

$(selector).offset({top:value, left:value})

Set the offset using a function:

$(selector).offset(function(index, currentoffset))

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
{top:value,left:value}Specifies the top and left coordinates in pixels (required when setting the offset)

Possible values:

  • index - returns the index position of the element in the set
  • An object with top and left properties
function(index,currentoffset)Specifies a function that returns an object containing the top and left coordinates

  • index - returns the index position of the element in the set
  • currentoffset - returns the current coordinates of the selected element

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.
