Quick Reference
The :parent selector selects all specified html elements that have child elements or text.
// selects all HTML paragraphs that have child elements or text
$('p:parent')Additional Info
Selecting Multiple Elements
To select multiple HTML elements with varying ids and classes, separate them with commas. The following will select 4 different elements based on their ID, class, or tag.
$('#intro, #footer, .my_paragraphs, h3')Increasing Specificity
To be more specific when selecting an HTML element, you can refer to the element and an ancestor element.
// all .child elements that live within a .father element
$('.father .child')
// all h1 tags that live within a .father element
$('.father h1')Notice that there is no comma between the classes (but there is a space), which says you are targeting the class .child and it must have an ancestor with the class .father, as shown in the first example. You can include as many ancestors as necessary to be as specific as necessary.
// all p tags that live within a .child element that lives within a .father element
$('.father .child p')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.
