I have a project where users can interact with a carousel like slide show, and drag between slides instead of using an arrow/number navigation. JS is based on the following plug in:
http://nooshu.com/explore/jquery-iphone-animation/
The issue is, in IE, if a user grabs inside the carousel and the mouse leaves the container element, the UI freaks out. If you play around with it, you'll see what I mean.
Is there a way to tell IE to handle the drag/click event to mimic firefox and chrome? I'm sure this is a common problem with IE and UI design.
Help!
EDIT: This also happens in Chrome. Firefox is the only browser that handles this in an intuitive way.
When, in IE, the mouse leaves the square, it's not releasing the mousedown event. So even when you let the button go, the plugin still thinks that the mouse is down.
Is it possible then that you wrap the plugin in say a div and on the div have a mouseleave event and force the plugin to execute mouseup?
I think you should be able to use the jQuery keyword "trigger" to do it.

I'm using the idangerous "Swiper" slider. One of my slides has a textarea in it that is causing issues. Everything is OK on the desktop, but on mobile when entering text in the textarea, Swiper seems to reinitialize and return to the first slide.
As this happens on mobile only, I am guessing it is related to one of the touch events firing in the text area.
As suggested in another post I have applied:
$('textarea#text_area_name').on('touchstart mousedown', function(e){
e.stopPropagation()
})
This didn't solve the problem, so I extended it to include all touch events. And then all parents (until the swiper wrapper). Still with no success.
I have tried using alerts to show which touch events are firing. But I can't see the event that is fired immediately before the before swiper resets.
Does anyone have any experience of using a textarea within the idangerous swiper slider? Or any ideas on what event may be causing the issue and how to prevent it?
Sometimes when you write the question down the answer becomes clearer...
I was reinitializing Swiper on window.resize to manage the dynamic sizing. The resize event was getting triggered by the textarea on mobile devices. Maybe this is due to the soft keyboard popping up. Anyway, removing the reinitialize on resize solved the problem.
I'm creating a simple javacript window manager with basic functions like all windows managers(moving, resizing, depth-sorting, etc).
I'm using events like mousedown and mouseup to know when to move the window or not.
However, sometimes, when I try to move the window, chrome hooks up on it and drags the "content"(I don't know the right word to use here, just imagine you're dragging an image from the browser to your desktop), like the image below.
(My cursor is there, it just doesn't appear on the screenshot).
Whenever this happens, chrome just simply don't trigger the mouseup event when i release the button, so the windows keeps following the mouse until I click again.
Is there any workaround to make chrome don't activate its dragging system?
Thanks.
Here's a link to another question very similar to yours. It seems to have a variety of answers. Disable Drag and Drop on HTML elements?
Try adding the draggable="false" attribute to relevant elements. By default <img> and <a> elements can be dragged, as can selected text (not much you can do about that one).
Alternatively, try adding ondragstart="return false;" to the document.
I'm using Sencha Touch 2.1. I have Ext.carousel.Carousel container and bunch of Ext.dataview.Dataview as pages inside carousel.
On each dataview I have a lot of buttons (rendered using CSS - so they are not buttons controls but simple divs with fancy styles). I'm trying to catch itemtap event when user taps on the "button".
Everything works fine in browser on the desktop. On the iPad however touch sensitivity is different and often I will not get itemtap event when user not carefully and somewhat slowly taps on the button. Carousel would start moving slightly as in swipe event was detected and carousel needs to change pages.
I tried to replace itemtap and use itemtouchstart instead. Button responsiveness got significantly better, but I often see false positives when user legitimately swipes between pages.
I'm stuck. I want to have responsive buttons and also swipe across to change pages.
Anybody seen something similar? Or solve it somehow?
This is a known issue check out this forum post in sencha forum. Tragically i have the same issue & at the moment it cannot be solved using sencha alone perhaps a solution is available in phonegap but i dont know.
I have made an image gallery in HTML5, JavaScript and CSS by using jQuery mobile. IE Phonegap platform ok.
The images are coming dynamically and are loaded in it, like this:
http://torontographic.com/wordpress/mouseSwipe/mouseSwipe.html
Above mouseSwipe Slider:
TYPE: 'mouseSwipe'
HORIZ: true
plugin available at
torontographic.wordpress.com
The problem coming with it is that I cannot click on the image and go to next page, because two events are occurring together.
The second problem is that I cannot swipe the page up down, from the place where gallery is placed, except the other area where gallery is not present.
To make it more clear, I am making news application in which I have added 5 - 10 gallery like Pulse news application.
I'm a little confused about some of the details of the issue, but I hate to see this question go completely unanswered in case someone else has this issue.
This plugin (mouseSwipe) overrides the default dragging functionality for mobile devices. Whereas normally devices would scroll the page on the mouse starting event, this plugin overrides that behavior to detect click movement across an element. Since it interrupts that functionality, dragging the opposite direction (for scrolling) is also broken. If the plugin were still being maintained by the owner (it doesn't appear to be), it could be updated to fix this issue, or emit events that could be used to manually create the functionality you're wanting.
I assume this is also what is giving you trouble for clicking to go to the specified page.
If you want my honest opinion, I would choose a different library, perhaps one that focuses solely on the swipability of mobile devices, and then handle desktop functionality separately (though, if you're using PhoneGap, it's likely you aren't even publishing this to a web platform for desktops). If it's going to be on the web, you can use modernizr (or the like) to figure out if the device supports touch input, and then implement something like the following:
http://labs.rampinteractive.co.uk/touchSwipe/demos/Image_gallery_example.html
For devices that do not support touch, you could fall back to button/arrow-based navigation (after all, as a desktop user, I do not expect to be able to drag it back and forth with the mouse).
In the file http://torontographic.com/wordpress/mouseSwipe/jquery.mouseSwipe.js onmousedown function has the code below. This will stop the event from the default behaviour and in cases stop captured/bubbled. You may want to look at these or the way event are being handled by the libraries.
e.preventDefault()
Here is more on how to stop JQuery propagation and regular behaviour.
event.preventDefault() vs. return false
What is event bubbling and capturing?
The reason you cannot swipe up and down is likely due to that the "swipe" event is hogging the "movestart" or "move" event.
I ran into a similar problem once when using this plugin:
http://stephband.info/jquery.event.swipe/
Their solution as pointed on on their website was to call the preventDefault method on the event to keep it from blocking as seen here.
jQuery('.mydiv')
.on('movestart', function(e) {
// If the movestart is heading off in an upwards or downwards
// direction, prevent it so that the browser scrolls normally.
if ((e.distX > e.distY && e.distX < -e.distY) ||
(e.distX < e.distY && e.distX > -e.distY)) {
e.preventDefault();
}
});
I have no experience with jQuery mobile, but i would reckon the problems are similar.
Background: I am creating a table reminiscent of whenisgood.net, in that it has click-n-drag toggling for table elements. I want to call different types of toggling code when the left, middle, and right mouse buttons activate a mousedown event.
By using JQuery, I'm off to a good start.
$(".togglable").bind("contextmenu", function() {return false;});
$(".togglable").bind("mousedown", function(e){
e.preventDefault();
toggle(this, e);
});
In the toggle() function I can use e.which to determine what button was clicked.
The punchline: I used e.preventDefault() hoping that it would stop the middle click default behavior of scrolling. It didn't. What can I do to stop the scroll action from activating?
See also "Triggering onclick event using middle click"
Middle-click can be disabled with Javascript, but only in IE, WebKit, and Konquerer. Firefox requires a config file edit. It's 2017 and firefox 50 supports this.
This is an old question...but if I'm understanding it properly, you want to disable scrolling via the middle mouse button click.
Nowadays, you can do this with a single line of vanilla JS:
document.body.onmousedown = function(e) { if (e.button === 1) return false; }
Currently, my solution is this: (more jquery!)
$(".togglable").wrap(
"<a href='javascript:void(0);'
onclick='return false;'></a>"
);
By wrapping it in a link (via jquery wrap), browsers think it's a link and don't scroll on middle click, even if you drag your mouse around. With this setup, and my situation, there are a couple (minor) gotchas.
Firefox will open a new tab when you middle click, but only if you don't drag. Opera will open a new tab when you middle click, drag or not. That's why I used href='javascript:void(0);' instead of just href='#'--so that the client's browser wouldn't load a whole page, just a blank page with a strange url.
But this solution works like a charm on Chrome and Safari. It works well with IE8, except that now when I left-click-n-drag, it changes the pointer to a "can't do that" symbol, since it thinks I want to drag the link somewhere. Untested on older versions of IE.
It is a bit old thread already, but I've tried hard to circumvent this in Firefox (I'm still using 3.6) and I'll share my findings, maybe someone will find it helpful.
Check that if you create an empty HTML file (or a small document with couple of paragraphs) and load it in Firefox, middle click scrollbar does not appear. This is because <body>'s width and height are smaller than window size. If you put a lot of <br>'s, this is not the case and scrollbar appears on middle click.
Google managed to prevent middle click scroller to appear in Google Maps in Firefox by making sure (through JS) that <body> size is always less than window size, plus additionally putting
<body style="overflow:hidden;">.
This is hardly achievable in general case, but sometimes might be useful.
