How to disable contextmenu in chrome while on a touch screen. This pops up on selection/on long tap of any text. Is there any solution which we can manage using css or javascript.
you can try to add a listener, that catchs every touch on a section
document.getElementById('yoursection').addEventListener('touchstart', (event) => {
event.preventDefault();
})
but note, that in that section nothing more can be touched ...

I am working on an application using javascript and I want to get mouse events. To stop the options that appear when right clicking I use the preventDefault() function and it works in Firefox and Chrome but it doesn't work in Safari. This is my code:
document.querySelector("#GL-Surface").addEventListener("mousedown", function(e) {
e.preventDefault();
/* Handle mouse events */
});
From an other question I got that you should return false; but this still doesn't work. preventDefault() however works in Safari when it is used in keyboard inputs. So how can I prevent the default actions for mouse events in Safari?
To target right click events, use contextmenu rather than mousedown.
document.querySelector("#GL-Surface").addEventListener("contextmenu", function(e) {
e.preventDefault();
});
Note that the options that appear on right click do appear only when the right click button is released, so I don't think mousedown is at all suitable here.
On my webpage, I have a "register now" button in the header. On click this button will scroll the user to the bottom of the page and will, ideally, focus on a form field input and open the soft keyboard on mobile devices.
I am currently executing a .focus and .click state to the element after the smooth scroll function ends. While these two statuses are being applied, they are not opening the keyboard as desired.
componentDidMount = () => {
Events.scrollEvent.register('end', function(to, element) {
if(element.id === 'request-demo'){
var inputFocus = document.getElementById('name');
inputFocus.focus(console.log("focused"));
inputFocus.click(console.log("clicked"));
}
Events.scrollEvent.remove('end');
});
}
This function will open the keyboard on Android devices, but not IOS.
I am avoiding jQuery for this project, so vanilla solutions would be preferred
IOS will not allow developers to simulate user inputs within react-scroll's scrollEvent. By removing the focus and click states from within the end of scroll event, we were able to resolve this issue
Our current interpretation is that IOS blocks developers from simulating user inputs within on event functions, however any further insight would still be greatly appreciated
I'm trying to completely remove the vibration that occurs on a long press of an element in a mobile browser.
Specifically, I have an image that I'm adding my own long-press functionality to, but the subtle short-vibrate that happens by default is interfering and I need to disable it.
I've successfully stopped the usual context menu from appearing by overriding it as follows:
window.oncontextmenu = function (event) {
event.preventDefault();
event.stopPropagation();
return false;
};
I've also added CSS to stop highlights and text selection etc - but I haven't been able to figure out what's causing the default vibrate after a few hundred ms.
Is there another lifecycle event that's popped on a long-press in a mobile browser, in or around oncontextmenu?
Full plunker Example here, long-press on the image from a mobile browser (I'm using chrome on Android) to see what I mean: https://plnkr.co/edit/y1KVPltTzEhQeMWGMa1F?p=preview
Disable the text selection when its clicked on.
document.querySelector("#your_target").addEventListener("touchstart", (e) =>
{
e.preventDefault();
e.stopPropagation();
this.style.userSelect = "none";
});
document.querySelector("#your_target").addEventListener("touchend", (e) =>
{
e.preventDefault();
e.stopPropagation();
this.style.userSelect = "default";
});
You could use touch-action: none; in CSS. Then you might be able to handle an interaction event to do what you want.

I'm struggling to disable default taphold browser event. Nothing that I have found on Google provided any help. I have only Android 4.4.4 mobile and Chrome dev tools for testing. I tried CSS fixes, such as webkit-touch-callout and others, but apparently they don't work for Android, also they don't work in Chrome dev tools.
I also tried detecting right click, (e.button==2), it doesn't work.
I came up with a solution, but it solves one problem and creates another. I just want to have a custom action for 'long press' event for selected anchors and I don't want the default pop up to appear (open in a new tab, copy link address, etc.)
This is what I did:
var timer;
var tap;
$("body").on("touchstart", my_selector, function(e) {
e.preventDefault();
timer = setTimeout(function() {
alert('taphold!');
tap=false;
},500);
});
$("body").on("touchend", my_selector, function() {
if(tap) alert('tap');
else tap=true;
clearTimeout(timer);
});
It successfully disables the default taphold event and context menu doesn't appear. However it also disables useful events, such as swipe. The links are in a vertical menu and the menu is higher than the screen, so a user has to scroll it. If he tries to scroll, starting on an anchor, it won't scroll, it will alert 'tap!'
Any ideas how could I disable taphold default or how could I fix this code so it disables only tap events and leave default swipe events enabled?
Edit: Now I thought about setting a timeout, if the pointer is in the same place for lets say 100ms, then prevent default action. However e.preventDefault(); doesn't work inside setTimeout callback.
So now I'm just asking about the simplest example. Can I prevent default actions after certain amount of time has passed (while the touch is still there).
And this is my whole problem in a fiddle. http://jsfiddle.net/56Szw/593/
This is not my code, I got this from http://www.gianlucaguarini.com/blog/detecting-the-tap-event-on-a-mobile-touch-device-using-javascript/
Notice that while swiping the box up and down, scrolling doesn't work.
I got the solution. It was so simple! I had no idea there's an oncontextmenu event. This solves everything:
$("body").on("contextmenu", my_selector, function() { return false; });
For an <img> I had to use event.preventDefault() instead of return false.
document.querySelector('img').addEventListener('contextmenu', (event) => {
event.preventDefault();
}
We are using W2UI (Javascript UI) controls. It has a "Multi Select" input control with associated div container with suggestion data. Whenever user clicks on input control a suggestion div is popped up and user can select multiple items from the list. Please find below screenshot
We have set overfloaw:auto of div When suggestion list has more than 10 records. (Refer below screenshot)
At this point, clicking on scrollbar works fine in Chrome and Mozilla but in case of IE it closes / hides the div.
We have made initial RCA of this as follow.
When a scrollbar is associated to a div, clicking on scrollbar causes blur event to fire for that div.
In W2UI library, blur event is used to hide the suggestion div causing it to close. We also found that, clicking on scrollbar does not cause blur event to fire in chrome & firefox.
Now we want to suppress blur event when user clicks on "scrollbar" in case of IE.
We are unable to identify scrollbar click.
Please share your thoughts / workarounds about suppressing blur() event conditionally.
I am also facing same issue we have made some changes in w2ui lbrary
we have set global variable flagClick first time it is false. & added below events
var div = $('#w2ui-global-items');
div.on('mouseover', function (event)
{
flagClick = false;
$('.w2ui-list').find('input').focus();
});
div.on('mouseout', function (event)
{
flagClick = true;
});
and changed blur event logic of div
as below --
.on('blur', function (event)
{
if (flagClick)
{
$(div).css('outline', 'none');
obj.hide();
if (event.stopPropagation) event.stopPropagation();
else event.cancelBubble = true;
}
})
almost this logic have solved our issue, except one .
When we click on search textbox then list will populate , if after that we click on list scroolbar and after that click on outside list div , List not getting hide (div blur event not getting fired).
try this solution , it will help u .
If you get solution to our problem pls post on same .
An updated version of w2ui came out just a few days ago where controls, including multiselect, have been refactored. It seems to work fine for me with 1.4 version.
