jQuery - resize() method

This method is a shorthand for the .on('resize', handler) or .trigger('resize').
The resize event is sent to the window element when the dimension in the browser window changes.

Syntax:

Trigger the resize() method for an element:

$(selector).resize()

Attach a function to the resize resize event:

$(selector).resize(function)

Example:

$( window ).resize(function() {
 $( "#log" ).append( "resize() method called" ); 
}); 

In this example, a message is concatenated to the < div id="log"> each time the window is resized.
