Android done/go/enter does not fire any DOM event in Cordova

The Issue:
Using
<input id="my_tel" type="tel" onkeypress="alert(event);"/>
<input id="my_num" type="number" onkeypress="alert(event);" />
The issue is that pressing done or enter or go key in android, nothing happens.For all other keys it works fine. When i tried to alert what event is being fired i found none.
The keypad does not hide (which is very sad) on pressing go/enter/done button.
However using
input type="text"
the issue does not exist.
Here is what i tried :
A. Used input type="text" and do not allow user to enter anything except
numbers.
Problem with this approach : The user is always presented with the default textual keyboard, and she/he has to switch, from default text to number pad,
which is not elegant and a turn off as i have many such pages in my project.
B. Used events like 'touchstart'and 'touchend' but no luck.
C. The input box is not even losing focus on key press so the solution
html phonegap android : numeric soft keyboard has next instead of go button is not useful.
Possible solution :
We can use the SoftKeyBoard plugin (https://github.com/phonegap/phonegap-plugins/tree/master/Android/SoftKeyboard). And hope that this problem is solved by this. But seriously can't there be a better solution??
Note : The problem is not observed in the iOS app,just android.
Another Note : No DOM event is fired even on pressing backspace key, but atleast the the backspace key is doing its job. In my case the done/go/enter key does not seem to execute its default behavior.

are you using iScroll?, if you are try removing it for a quick test and see what happens. I use it on a phonegap app and it's doing strange things with the inputs.

jQuery.mobile popup immediately hides after showing

I have a small phonegap application with jquery mobile and backbone.
I'm trying to show popup to user by manually calling .popup() method.
Everything works fine on iOS but on android I got strange issue: popup is showing for few moments and than disappear.
Here the actual code:
var PostView = Backbone.View.extend({
events: {
'touchend .add-comment-button': 'addComment'
},
addComment: function() {
this.$(".comment-popup").popup('open', { history: false });
return false; // Stop bubbling.
}
});
I'm using history: false because this popup is actualy part of subpage.
The code looks very simple, I'm just can't understand why it can disappear, and why this happen only on android devices.
Thanks, and sorry for my bad english.

I spent hours trying to fix this problem.
Finally I ended up doing the following two things that seemed to fix the problem.
1 - Use the uncompressed jqm file. i.e jquery.mobile.1.2.0.js
2 - I was triggering the popup programatically using the 'tap' option - once changed to the 'click' option it worked.
$('.option').live('click', function() {
$('#popup-div').popup('open');
});

I spent hours trying to fix this problem.
Finally I ended up doing the following two things that seemed to fix the problem.
this code snippet may help you ->
$('#testBtn').on('tap',function(e){
console.log("button clicked");
e.preventDefault();
$('#testPOPUP').popup("open");
});
Please note i have used e.perventDefault().

I didn't feel like changing my .tap() events to the click event and I didn't have a case where I could use preventDefault()so I just added a timeout to the popup('open') line. My hoverdelay in jqm is set to 150 so I set this timeout to 600 just to be on the safe side. Works fine, doesn't feel sluggish for the user.

One way to 'fix' it is by setting data-history="false" on the popup div

JQuery Mobile popup with history=false autocloses

I have the exact same problem when trying to use popup('open') on an android 2.3 device (both in native browser and in firefox) and it works just fine on browsers on other devices. I'm also using backbone event management to open my popup (used the tap event and no aditionnal options to popup).
What I did to 'correct' the problem is that I removed the backbone event management for this event and added a listener in the render function. In your case this would look something like this :
events: {
// 'touchend .add-comment-button': 'addComment'
},
render: function() {
$(this.el).html(this.template(this.model));
$(this.el).find('.add-comment-button').tap(function(el){
this.addComment(el);
return false;
}.bind(this));
}
I have no idea where the problem comes from (must be some incompatibility between backbone and jquery mobile) and why we only see it on android but for the moment with this workaround my app seems to work fine on any device.
Edit: oops, it turns out that in my case the problem was I was missing "return false;" in the function dealing with the event.
Now that I added it, it works correctly with the backbone event management.
Sadly that doesn't explain why you have the issue and why I was seeing it only on android.

In case it helps anyone, I had the same problem occurring with Bing Maps, with the Microsoft.Maps.Events.addHandler(pin, 'click', callback) method.
Not particularly nice, but instead I stored an ID in pushpin._id and did the following:
$("#page").on('vclick', function (event) {
if (event.target.parentElement.className === "MapPushpinBase") {
$("#stopPopup").popup('open');
}
});

One brute force option is to check whether popup was hidden and reopen it.
In a loop, because the exact time the popup becomes hidden seems to be varied.
var hidden = $('#' + id + '-popup') .hasClass ('ui-popup-hidden')
if (hidden) $('#' + id) .popup ('open')
A working example: http://jsfiddle.net/ArtemGr/hgbdv9s7/
Another option could be to bind to popupafterclose:
var reopener = function() {$('#' + id) .popup ('open')}
$('#' + id) .on ('popupafterclose', reopener)
$('#' + id) .popup ('open')
Like here: http://jsfiddle.net/ArtemGr/gmpczrdm/
But for some reason the popupafterclose binding fails to fire on iPhone 4 half of the time.

force keyboard open on android

does anybody knows how to force keyboard open on android browser (4.0 - maybe less)?
i tried this solution and it does not worked for me.
in project i am trying to get a text input working, but after submitting (intercept by jQuery) it holds focus but the keyboard disappears.
snippets:
$('#typer').blur(function () {
$(this).focus().click();
});
$('#typer').bind('keyup', function (e) {
var input = $.trim($(this).val());
// some lines of code..
$(this).val('').focus(); // clean up
}
iOS is also interesting.. but not tested yet.

Android pulls up soft keyboard whenever text input field is in focus. "Go" or "Done" button on Android works as form submit, therefore input text looses focus and keyboard disappears. User expects the keyboard to disappear after "Go", "Done" or "Enter" is pressed - so Android follows this rule. Forcing re-focus on field's blur will not do much since technically you moved to a different window.
$('body').click(function() { $('#typer').focus(); }
can provide a partial solution, whereby user has to click once anywhere in the body of the page for the typer to re-gain focus. It causes OS to move back to browser Activity and focus the input field. This fiddle shows it as an example: http://jsfiddle.net/Exceeder/Z6SFH/ (use http://jsfiddle.net/Exceeder/Z6SFH/embedded/result/ on your Android device)
Other than writing a PhoneGap-like wrapper to control imeOptions of the keyboard, I am not aware of any solution that can solve this problem.

android browser timers when keyboard is open

I have run into this issue where asynchronous functions do not execute when the soft keyboard is open in the android browser.
For example:
<input type='text' id='foo'/>
....
document.getElementById("foo").addEventListener("keyup", function() {
window.setTimeout(function() { alert("1"); }, 20);
}, false);
You will never see the alert as long as you remain focused on the text input. This is true for xhr callbacks as well. If you attempt to make an ajax request, the request is sent, but the oncomplete callback is never fired until after you type another character in the textbox.
Does anyone know a workaround? You can see that Google obviously has a working example with their search suggestions, though I've not yet been able to figure out what exactly their solution is yet by looking at the minified/obfuscated source.
Any insight appreciated, Thanks

Using the newest jquery lib in the style of
$("#inputnum").keyup(function(e){
if (e.keyCode != '13') {
$("#outputarea").slideUp('slow');
};
});
causes the item selected with "#outputarea" to be slid up every time - as soon as I type any letter on the software keyboard or a hardware keyboard. Might want to give the jquery lib a shot? Cross-browser compatibility is the main reason I keep going back to it.

What DOM events are available to WebKit on Android?

I'm building a mobile web app targeting Android users. I need to know what DOM events are available to me. I have been able to make the following work, but not terribly reliably:
click
mouseover
mousedown
mouseup
change
I have not been able to get the following to work:
keypress
keydown
keyup
Does anyone know the full list of what is supported and in what contexts (e.g., is onchange only available to form inputs?)? I can't find a reference for this on The Googles.
Thanks!
Update: I asked the same question on the Android developers list. I will be doing some more testing and will post my results both here and there.

OK, this is interesting. My use case is that I have a series of links (A tags) on a screen in a WebKit view. To test what events area available, using jQuery 1.3.1, I attached every event listed on this page (even ones that don't make sense) to the links then used the up, down, and enter controls on the Android emulator and noted which events fired in which circumstances.
Here is the code I used to attach the events, with results to follow. Note, I'm using "live" event binding because for my application, the A tags are inserted dynamically.
$.each([
'blur',
'change',
'click',
'contextmenu',
'copy',
'cut',
'dblclick',
'error',
'focus',
'keydown',
'keypress',
'keyup',
'mousedown',
'mousemove',
'mouseout',
'mouseover',
'mouseup',
'mousewheel',
'paste',
'reset',
'resize',
'scroll',
'select',
'submit',
// W3C events
'DOMActivate',
'DOMAttrModified',
'DOMCharacterDataModified',
'DOMFocusIn',
'DOMFocusOut',
'DOMMouseScroll',
'DOMNodeInserted',
'DOMNodeRemoved',
'DOMSubtreeModified',
'textInput',
// Microsoft events
'activate',
'beforecopy',
'beforecut',
'beforepaste',
'deactivate',
'focusin',
'focusout',
'hashchange',
'mouseenter',
'mouseleave'
], function () {
$('a').live(this, function (evt) {
alert(evt.type);
});
});
Here's how it shook out:
On first page load with nothing highlighted (no ugly orange selection box around any item), using down button to select the first item, the following events fired (in order): mouseover, mouseenter, mousemove, DOMFocusIn
With an item selected, moving to the next item using the down button, the following events fired (in order): mouseout, mouseover, mousemove, DOMFocusOut, DOMFocusIn
With an item selected, clicking the "enter" button, the following events fired (in order): mousemove, mousedown, DOMFocusOut, mouseup, click, DOMActivate
This strikes me as a bunch of random garbage. And, who's that cheeky IE-only event (mouseenter) making a cameo, then taking the rest of the day off? Oh well, at least now I know what events to watch for.
It would be great if others want to take my test code and do a more thorough run through, perhaps using form elements, images, etc.

Since this is the second most popular Android + JavaScript post on SO (which is just a sad commentary on the state of web development targeting the Android platform), I thought it may be worthwhile including a link to pkk's touch event test results at http://www.quirksmode.org/mobile/tableTouch.html and also http://www.quirksmode.org/mobile/ in general.

As of Android 1.5, the same touch(start|move|end|cancel) events that the iPhone supports work in Android as well.
One problem I found was that touchmove ends get queued up. No workaround yet.
