I coded this:
$("#scroll-to-left-button").on("mousedown", function() {
var x = $("#scroll-area").scrollLeft();
$("#scroll-area").scrollLeft(x - 10);
});
$("#scroll-to-right-button").on("mousedown", function() {
var x = $("#scroll-area").scrollLeft();
$("#scroll-area").scrollLeft(x + 10);
});#container {
width: 50%;
height: 100px;
background-color: grey;
position: relative;
}
#scroll-area {
white-space: nowrap;
overflow-x: auto;
height: 100%;
}<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<div id="container">
<div id="scroll-area">
<div id="text">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.</div>
</div>
</div>
<button id="scroll-to-left-button">Scroll to left</button>
<button id="scroll-to-right-button">Scroll to right</button>You need to click the buttons pretty often to navigate through this container. Is there a way to let it based on the duration of the mouse press? Like if you keep the mouse pressed, it continues constantly scrolling? And if you stop, it stops.
Would be happy if someone could help me.
Here's a working solution. Also your code was a bit wet, so I refactored it a bit. You only need one mousedown event listener.
let interval;
$('.scroll-btn').on('mousedown', ({ target }) => {
const type = $(target).attr('id');
interval = setInterval(() => {
var x = $('#scroll-area').scrollLeft();
$('#scroll-area').scrollLeft(type === 'left' ? x - 10 : x + 10);
}, 50);
});
$('.scroll-btn').on('mouseout mouseup', () => clearInterval(interval));#container {
width: 50%;
height: 100px;
background-color: grey;
position: relative;
}
#scroll-area {
white-space: nowrap;
overflow-x: auto;
height: 100%;
}<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<div id="container">
<div id="scroll-area">
<div id="text">
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,
sed diam voluptua.
</div>
</div>
</div>
<button id="left" class="scroll-btn">Scroll Left</button>
<button id="right" class="scroll-btn">Scroll Right</button>Well, the mousedown and mouseup make a good pair, although you have used only mousedown :)
Here's a sample how it could be done.
Note that there're couple other things that could be done to this code for it to look nicer:
.on(... is not probably needed, you could just write it as .mousedown(...move="10" for the right button and move="-10" for the left one, and then just getting this value in order to add it to scrollLeft)var tmr;
$(".scroll-button").mousedown(function() {
//let's setup the timer here...
move = +$(this).attr("move");
tmr = setInterval(function(){
$("#scroll-area")[0].scrollLeft+=move;
}, 250)
});
$(".scroll-button").mouseup(function() {
// and destroy the timer here
clearInterval(tmr);
});#container {
width: 50%;
height: 300px;
background-color: grey;
position: relative;
}
#scroll-area {
white-space: nowrap;
overflow-x: auto;
height: 100%;
}<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<div id="container">
<div id="scroll-area">
<div id="text">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.</div>
</div>
</div>
<button class="scroll-button" move="-10">Scroll to left</button>
<button class="scroll-button" move="10">Scroll to right</button>
