jQuery Event ready() Method

Definition and Usage

The ready event occurs when the DOM (document object model) has been loaded, and the page

has been completely rendered (including images).

Because this event occurs after the document is ready, it is a good place to have all other jQuery

events and functions. Like in the example above.

The ready() method specifies what happens when a ready event occurs.

The ready() method can only be used on the current document, so no selector is required.

The three following syntaxes are allowed:

Syntax 1

$ ( d o c u m e n t ) . r e a d y ( f 􀁘 n c 􀁗 i o n )

Syntax 2

$ ( ) . r e a d y ( f 􀁘 n c 􀁗 i o n )

Syntax 3

$ ( f 􀁘 n c 􀁗 i o n )

Parameter Description

function Required. Specifies the function to run after the document has been loaded.

Tips and Notes

Tip: The ready() method should not be used together with <body onload="">.
