Hi steppohak,

You may have better luck finding help on developer-focused forums like StackOverflow:

• http://stackoverflow.com/questions/ta.../firefox-os

The following MDN (Mozilla Developer Network) page also has some documentation about touch events:

• https://developer.mozilla.org/en-US/d.../Touch_events

I hope you're able to find a solution. Please let us know if you have any other questions!

Hi Ralph,

thanks for responding. Unfortunately it does not really help me. (Perhaps I could get help with a workaround from StackOverflow, but I already did one myself - using buttons instead of swipe - at the cost of worse user experience). Both resources are more targeting web app developers, but this is an issue with the _implementation_ in Firefox OS 1.3 (at least for my make and model of device).

Notably the second has a section on "Handling the end of a touch" based on the "touchend" event - but my problem is that the "touchend" event never fires.

I have filed a bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1047804 but nothing has happened there so far.

Hi Steppohack,

Thank you for filing the bug and for providing additional details.

I know that there are apps with swipe capabilities that work well on the ZTE Open C, but I'm not sure how they implemented the swipe features.

I added QA to the bug so that they can investigate this issue.

Thanks,

- Ralph

Thanks Ralph!

Could you provide a pointer to (source for) other apps with swipe? Would be nice to see how they solved it.

Regardless, I think touchend should fire, so the bug should be fixed.

Hi Steppohak,

I don't know the source code of specific apps, but a lot of apps in the Marketplace as well as system apps incorporate swiping.

For example, please look at lines 95-104 of the Browser.js in the B2G's source code:

• https://github.com/mozilla-b2g/gaia/b.../browser.js

 /**
* Get elements from index.html.
* Add event listeners.
* Init BrowserDB and search engine.
*/
init: function browser_init() {
this.getAllElements();
// Add event listeners
this.urlBar.addEventListener('submit', this.handleUrlFormSubmit.bind(this));
this.urlInput.addEventListener('focus', this.urlFocus.bind(this));
this.urlInput.addEventListener('blur', this.urlBlur.bind(this));
this.urlInput.addEventListener('touchend', this.urlTouchEnd.bind(this));
this.urlInput.addEventListener('input',
this.handleUrlInputKeypress.bind(this));
this.urlButton.addEventListener('click',
this.handleUrlFormSubmit.bind(this));
this.tabsBadge.addEventListener('click',
this.handleTabsBadgeClicked.bind(this));

And there is also some Touch Events information on the following page:

• http://mobiforge.com/design-developme.../html5-mobile-web-touch-events

I hope this information is helpful. Please let us know if you have any questions.

Thanks,

- Ralph
