How to detect a long press on a div in Jquery?

Question

I would like to execute some function when the user presses for 2 seconds on a div.

Is it possible ?

Here is my code to detect the click on the div

$('div').mousedown(function() {

});

Answer 1

Just watch both mousedown and mouseup and calculate the difference. Here's an example.

(function() { 

    // how many milliseconds is a long press?
    var longpress = 3000;
    // holds the start time
    var start;

    jQuery( "#pressme" ).on( 'mousedown', function( e ) {
        start = new Date().getTime();
    } );

    jQuery( "#pressme" ).on( 'mouseleave', function( e ) {
        start = 0;
    } );

    jQuery( "#pressme" ).on( 'mouseup', function( e ) {
        if ( new Date().getTime() >= ( start + longpress )  ) {
           alert('long press!');   
        } else {
           alert('short press!');   
        }
    } );

}());
