jQuery syntax

jQuery Syntax

All jquery methods are inside a document ready event:

$(document).ready(function(){

..... jQuery functions

});

OR

$(function(){

..... jQuery functions

});

this prevents the jQuery code to execute before the document is loaded or ready.

the basic syntax of jQuery is:

$(selector).action();

$ -> sign to define jQuery.

(selector) -> to find HTML elements

.action () -> action to be performed on the HTML element(s).

Example:

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

$("p").hide(); -> hides all <p> elements

$("h2").hide(); -> hides all <h2> elements

$(".myclass").hide() -> hides all elements with class="myclass"

$("#myid").hide() -> hides all elements with id="myid"
