Do something when window has stopped resizing; after user has finished dragging window. This is more efficient than just using .resize() which will fire thing incrementally while the user may still be dragging.

var rtime = new Date(1, 1, 2000, 12,00,00);
var timeout = false;
var delta = 200;
$(window).resize(function() {
    rtime = new Date();
    if (timeout === false) {
	timeout = true;
	setTimeout(resizeend, delta);
    }
    
});

function resizeend() {
    if (new Date() - rtime < delta) {
	setTimeout(resizeend, delta);
    } else {
	timeout = false;
	
	// do something
        var curWinWidth  = $(window).width();
        if ( curWinWidth < 1810) {
	       
		// do something
       	}	 
    }               
}
