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() {

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

Here is my code to detect the click on the div
$('div').mousedown(function() {
});
Add a throttle that only allows the click to happen after 2 seconds of mousedown.
var timer;
$('div').on("mousedown",function(){
timer = setTimeout(function(){
alert("WORKY");
},2*1000);
}).on("mouseup mouseleave",function(){
clearTimeout(timer);
});
Edit: I added mouseleave too since if the mouse leaves the element and then triggers mouseup, it won't stop the timer.
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!');
}
} );
}());
In the two years since this question was asked an awesome plugin called jQuery Finger was invented:
http://ngryman.sh/jquery.finger/
$('div').on('press', function(e) {
console.log(this, e);
});
I know this question is pretty old now, but I was looking for something like this and found that Buley's answer was close to what I needed. I figured I'd post what I've done with it to have it function without the mouse up, sort of like an Android longtouch.
// Set the duration of the long press and declare a couple variables
var longpress = 1000;
var start;
var divMouseDown;
// Check for mousedown on the element of choice
$("#element").on('mousedown', function(e){
// Get the time it was clicked
start = new Date().getTime();
// See if mouse is still being held down after the longpress duration
divMouseDown = setTimeout(function(){
// What we want to happen when mouse is clicked and held for 1 second
}, longpress);
// If the mouse leaves the element or is released before the long touch event,
// reset variables and stop the function from triggering
$("#element").on('mouseup mouseleave', function(){
if (divMouseDown) {
clearTimeout(divMouseDown);
}
start = 0;
e.stopPropagation();
} );
} );
Short-click & Long-click events - short press prevented in long press
//from e-OS menu script
var longpress = 800;
var start;
var timer;
//short press - show e-OS system menu
//long press - show e-OS settings
$( "#e-OS-menu" ).on( 'mousedown', function( e ) {
start = new Date().getTime();
timer = setTimeout(function(){ console.log('long press!'); }, longpress)
}).on( 'mouseleave', function( e ) {
start = 0;
clearTimeout(timer);
}).on( 'mouseup', function( e ) {
if ( new Date().getTime() < ( start + longpress ) ) {
clearTimeout(timer);
console.log('short press!');
}
});
So this is obviously a long way in the future, but for people who want to do this still, a super simple and pretty elegant way to do this is by combining the clearTimeout function with mouseup / mouseout events:
$('#button').mousedown(function(){
var timer = setTimeout(
() => {alert('long press occurred');}, 600
);
}).mouseup(function(){
clearTimeout(timer);
}).mouseout(function(){
clearTimeout(timer);
});
#button {
width: 50px;
height: 50px;
background-color: blue;
color: white;
display: flex;
flex-direction: column;
text-align: center;
justify-content: center;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="button">press here</div>
You can use the following code (tested in JSFiddle):
$('#foo').mousedown(function(){
$(this).data('lastPressed', new Date().getTime());
}).mouseup(function(){
var lastPressed = $(this).data('lastPressed');
if (lastPressed){
var duration = new Date().getTime() - lastPressed;
$(this).data('lastPressed', false);
if (duration > 2000) {
alert('Your click lasted more than 2 seconds.');
} else {
alert('Your click lasted less than 2 seconds.');
}
}
}).mouseout(function(){
$(this).data('lastPressed', false);
});
Upgrading and merging Editor and Kevin B replies you can have a fully functional, multi divs, hold-catcher with:
// Global delta msec timeout
var delta = 1500;
$("#foo").on('mousedown', function(event) {
var thisElement = $(event.currentTarget);
var deltaTimer = setTimeout(function(){
console.log('long press!');
thisElement.removeData('startTimestamp');
}, delta);
thisElement.data('startTimestamp', new Date().getTime());
thisElement.data('timer', deltaTimer);
}).on('mouseleave', function(event) {
var thisElement = $(event.currentTarget);
clearTimeout(thisElement.data('timer'));
thisElement.removeData('startTimestamp');
thisElement.removeData('timer');
}).on('mouseup', function(event) {
var thisElement = $(event.currentTarget);
var startTimestamp = thisElement.data('startTimestamp');
clearTimeout(thisElement.data('timer'));
if (startTimestamp !== undefined && !isNaN(parseInt(startTimestamp))) {
if (new Date().getTime() >= (startTimestamp + delta))
console.log('long press!');
else
console.log('short press!');
}
thisElement.removeData('startTimestamp');
thisElement.removeData('timer');
});
This solution executes the action after the time you set. It also cancels the action if you leave the pressed element with the mouse.
var longpress={
pressed:false,
longpressed:false,
presstime:1000
};
$('#element').on( 'mousedown' , function( event ) {
longpress.longpressed=false;
longpress.pressed=true;
longpress.timeout=setTimeout(function() {
longpress.longpressed=true;
//Long press action here!
},longpress.presstime);
}).on( 'mouseup' , function( event ) {
clearTimeout(longpress.timeout);
if (!longpress.longpressed && longpress.pressed) {
longpress.pressed=false;
//Short press action here!
}
}).on('mouseleave', function( event ) {
clearTimeout(longpress.timeout);
longpress.pressed=false;
});
You can get the timestamp when you detect the click on the div thanks to mousedown
. Similarly you can get the timestamp when you detect the click release thanks to mouseup
.
You then need to compare these two timestamps, if they are greater than 2 seconds (or 2000milliseconds) then you execute your function.
Simple. No need for long uneccesary coding.
(function(){
// how many milliseconds is a long press?
var offset = 500;
$(".button").on('mousedown', function(e){
// holds the start time
$(this).data('start',new Date().getTime());
$(this).addClass("selected");
}).on('mouseup', function(e){
if (new Date().getTime() >= ($(this).data('start') + offset)){
//alert('ur click lasted for over 2 secs');
$(this).addClass("selected");
}else{
$(this).removeClass("selected");
}
}).on('mouseleave', function(e){
start = 0;
//you can add destroy lingering functions on mouse leave
});
}());
We can calculate the time difference when the mouse clicks and leave. We can get the timestamp
when you click and release a button
or div
using mousedown
and mouseup
Here's an example to detect the simple click and 2 seconds
long press. Here I have done with a button
press. Similarly, you can use div
$(document).ready(function () {
var pressTime; // store the press time
$("#pressHere").on('mouseup', function () {
var holdTime = 2000; // 2 seconds for long press
if (new Date().getTime() >= (pressTime + holdTime))
$("#status").text("It's a Long Press...");
else
$("#status").text("It's a Short Press...");
}).on('mousedown', function () { // When Button Release
pressTime = new Date().getTime();
}).on('mouseleave', function () { // When Button Leave
pressTime = 0;
});
});
.input-bar-item {
display: table-cell;
}
.button-item {
margin: 20px;
width: 30%;
}
.width100 {
width: 60%;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="input-bar-item button-item">
<button class="btn btn-info" id="pressHere">Press Me</button>
</div>
<div class="input-bar-item width100" id="status"></div>
My solution
Usage:
$("#button").longClick(
function() { //longclick callback
console.log("long clicked");
},
function() { //click callback (optional)
console.log("clicked");
},
1000 //Time in ms. Optional
});
