JQuery syntax

The jQuery syntax is programmed for the selection of HTML elements, and certain actions can be performed on elements.

The basic syntax is: $(selector) .action ()

The dollar sign defines jQuery

Selector (selector) "query" and "find" HTML elements

Action () of jQuery performs the operation on the element

Example

$(this) .hide ()-hides the current element

$("p") .hide ()-hide all paragraphs

$(".test") .hide ()-hides all elements of all class= "test"

$("# test") .hide ()-hides all elements of id= "test"

Tip: the syntax used by jQuery is a combination of XPath and CSS selector syntax. You will learn more about the syntax of selectors in the next chapters of this tutorial.
