The jQuery one() Method attached a handler for the selected elements and executed at most once per element per event type.
Using one() method, the event handler is only run ONCE for each element.
Possible event values are: blur, load, focus, resize, unload, scroll, click etc.
This is the simple syntax for using this method −
selector.one( type, [data], fn )
$( "#elementID" ).one( "click", function() {
alert( "Item will be displayed only once." );
}); Above code is equivalent with:
$( "#elementID" ).on( "click", function( event ) {
alert( "Item will be displayed only once." );
$( this ).off( event );
}); This is the description of all the parameters used by this method −
