Overview
In jQuery, you can chain together multiple methods (actions), allowing multiple actions to run on the same element(s), within a single statement.
The following chains together three methods to apply to the element with and id of #intro.
// change the color to red, slide the element up and then down
$('#intro').css('color', 'red').slideUp(1000).slideDown(1000);To make it more easily readable, it could also be written like this:
// change the color to red, slide the element up and then down
$('#intro').css('color', 'red')
.slideUp(1000)
.slideDown(1000);Note
jQuery ignores extra whitespace and executes the lines above as one long line of code.
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.
