Example of jQuery Syntax

1)

Basic syntax is: $(selector).action()

• A $ sign to define/access jQuery
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

2) Examples:

• $(this).hide() - hides the current element.
• $("p").hide() - hides all <p> elements.
• $(".test").hide() - hides all elements with class="test".
• $("#test").hide() - hides the element with id="test".

2) use of $(document).ready(function(){});

This is to prevent any jQuery code from running before the document is finished loading (is ready).
