I've got an issue while I'm trying to combine touchstart
and mousedown
in 1 function. I've used an a
tag as the target element of the function for going to the link directly when I touched or clicked the tag.
The issue is when I touch
the middle of a
tag, link doesn't respond. it only works when I click
the element or touch the edge of the a
tag, and the output fires mousedown
.
In the mobile mode, try to click the edge of a
tag as much as you would possible like a grey dot in the picture above. I've created an CodePen example for looking, testing and understanding better.
How would I fix this issue?
class Slider {
constructor($el, paragraph) {
this.$el = $el;
this.paragraph = paragraph;
}
start(e) {
e.preventDefault();
var type = e.type;
if (type === 'touchstart' || type === 'mousedown') this.paragraph.text(this.paragraph.text() + ' ' + type);
return false;
}
apply() {
this.$el.bind('touchstart mousedown', (e) => this.start(e));
}
}
const setSlider = new Slider($('#anchor'), $('.textbox'), {passive: false});
setSlider.apply();
a {
display: block;
width: 100px;
height: 100px;
background-color: orange;
}
<a id="anchor" href="https://google.co.uk">Tap or Click Me</a>
<p class="textbox"></p>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
========= Progress Update ==========
I've just added move
& end
function then I have to click twice for moving on to the linked website. It keeps getting worse and have no idea how to solve this issue.
class Slider {
constructor($el, paragraph) {
this.$el = $el;
this.paragraph = paragraph;
}
start(e) {
e.preventDefault();
var type = e.type;
if (type === 'touchstart' || type === 'mousedown') this.paragraph.text(this.paragraph.text() + ' ' + type);
this.$el.bind('touchmove mousemove', (e) => this.move(e));
this.$el.bind('touchend mouseup', (e) => this.end(e));
return false;
}
move(e) {
var type = e.type;
if (type === 'touchstart' || type === 'mousedown') this.paragraph.text(this.paragraph.text() + ' ' + type);
return false;
}
end(e) {
console.log('test');
this.$el.on('click');
this.$el.off('touchstart touchend');
return false;
}
apply() {
this.$el.bind('touchstart || mousedown', (e) => this.start(e));
}
}
const setSlider = new Slider($('#anchor'), $('.textbox'));
setSlider.apply();
======== Progress Updated After Bounty (Latest) ========
After dozens of tried, I've finally figured out and solve the previous problem but I've faced up a new issue that can't draggable and redirecting instantly.
When I use the preventDefault
in the start function, all of the events work fine. The only issue of this case is dragging doesn't prevent redirecting link from the a
tag. It always send me to the website no matter which ways to call the functions, clicked or dragged.
when I don't use the preventDefault
, dragging doesn't work. it only works clicking the elements.
My final goal is to prevent redirecting link of the a
tag from the both events, touchmove
and mousemove
. I've been searched about on google so many times but haven't got any of the clues.
I've written an example in Codepen and this is what I've done so far:
class Slider {
constructor($el, paragraph) {
this.$el = $el;
this.paragraph = paragraph;
}
start(e) {
var type = e.type;
if (type === 'touchstart') {
this.paragraph.text(this.paragraph.text() + ' ' + type);
} else if (type === 'mousedown') {
this.paragraph.text(this.paragraph.text() + ' ' + type);
}
}
move(e) {
var type = e.type;
}
end(e) {
var type = e.type;
if (type === 'touchend') {
console.log('touchstart enabled');
} else if (type === 'mouseup') {
console.log('mousedown enabled');
}
}
apply() {
this.$el.bind({
touchstart: (e) => this.start(e),
touchmove: (e) => this.move(e),
touchend: (e) => this.end(e),
mousedown:(e) => this.start(e),
onmousemove: (e) => this.move(e),
mouseup: (e) => this.end(e)
});
}
}
const setSlider = new Slider($('#anchor'), $('.textbox'));
setSlider.apply();
a {
display: block;
width: 100px;
height: 100px;
background-color: orange;
}
<a id="anchor" href="https://google.co.uk">Tap or Click Me</a>
<p class="textbox"></p>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
from How would I prevent redirecting of a href during touchmove and mousemove?
