ionic scroll: Prevent translate3d on parent element - angularjs

I have template in my ionic app that looks something like this:
<ion-view>
<ion-content>
<div class="nav">
<span class="ion-chevron-left" ng-click="goToMonth('thisMonth', $event)"></span>
<span>{{ monthName }}</span>
<span class="ion-chevron-right" ng-click="goToMonth('nextMonth', $event)"></span>
</div>
<ion-scroll on-scroll="onScroll()" class="wide-as-needed" delegate-handle="calendarScroll" direction="x" paging="true" scrollbar-x="false" style="min-height: 215px" ng-style="scrollStyle">
...
the div with the class 'nav' contains two buttons that let the user switch between two months. The months are in the <ion-scroll> element.
This works as it should. The buttons scroll the <ion-scrol> element horizontally. But every time the buttons are used, the entire <ion-view> is scrolled vertically down by 20px - thus hiding the buttons.
I've tried changing the <ion-scroll>s inline css (with angular.element) to not include 3d transforms, but they just get re-added.
This is the function that gets called upon click - and my attempt to prevent the transform3d on the parent element
$scope.goToMonth = function(id, event){
$location.hash(id);
if(id == 'thisMonth'){
$scope.monthName = monthLabels[thisMonth];
}
else{
$scope.monthName = monthLabels[nextMonth];
}
var elm = angular.element(document.querySelector('.nav'));
var parent = angular.element(elm.parent());
console.log(parent[0].style.transform);
parent[0].style.transform = 'none';
$ionicScrollDelegate.anchorScroll(true);
};
EDIT: I've also tried using event.stopPropagation - this breaks the functionality of the <ion-scroll> element
Can anyone tell me how to prevent this behaviour?

Silly me. It turns out this was very simple to solve. I simply just needed to add scroll="false" to the <ion-content> element. No additional controller logic was needed.
So the html code above now looks like this:
<ion-view>
<ion-content scroll="false">// <-- Here I altered the html
<div class="nav">
<span class="ion-chevron-left" ng-click="goToMonth('thisMonth', $event)"></span>
<span>{{ monthName }}</span>
<span class="ion-chevron-right" ng-click="goToMonth('nextMonth', $event)"></span>
</div>
<ion-scroll on-scroll="onScroll()" class="wide-as-needed" delegate-handle="calendarScroll" direction="x" paging="true" scrollbar-x="false" style="min-height: 215px" ng-style="scrollStyle">

Ionic continuous scroll

I'm looking for a way to implement a text continuous scroll
Basically, I would like to have an in-line text with time table for the next boat departures, and I would like to scroll it horizontally, both ways and continuously, like a carousel.
Is it possible ? How shall I do it ?
Thanks in advance
Directive <ion-scroll > works for scrolling .
<ion-scroll zooming="true" direction="x" style="width: 500px; height: 500px">
</ion-scroll>
Take a look of this http://codepen.io/rajeshwarpatlolla/pen/xGWBja
You can check my codepen, not perfect but maybe it will be helpfull.
http://codepen.io/kmlzjc/pen/bZjjRg
The thing is to use ion-infinite-scroll with ion-scroll or ion-content. Sth like this
<ion-content class="padding" >
<ion-scroll direction="x" class="item">
<div ng-repeat="scrollItem in scrollItems" class="scroll-item">
<strong>{{ scrollItem.id }}</strong>
<hr />
<span>{{ scrollItem.index }}</span>
</div>
</ion-scroll>
<ion-infinite-scroll on-infinite="load()" distance="20%"></ion-infinite-scroll>
</ion-content>
In this case when scroll will be 20% from the end, the load function will be fired so new data can be loaded. Here I do it with dummy function that adds new items to scrollItems list.
$scope.load = function() {
var previousLength = $scope.scrollItems.length;
for(var i = 0; i < 10; i++) {
$scope.scrollItems.push({
id: Math.random() * 1000,
index: previousLength + i + 1
});
}
$scope.$broadcast('scroll.infiniteScrollComplete');
};
And once the data is loaded there is an event broadcasted, to refresh scroll. $scope.$broadcast('scroll.infiniteScrollComplete');
Check also ionic scroll documentation http://ionicframework.com/docs/api/directive/ionScroll/. There will be an explanation on ion-infinite-scroll.

Override ng-hide on ng-click

On the process of trying to learn angularjs, I am creating a set of divs using ng-repeat. I have five divs in all. I am only displaying the first div using $firstdirective component.
<div class="container" ng-app="demoApp" ng-controller="demoController">
<div class="row" ng-repeat="job in jobs" ng-hide="!$first">
<div class="col-md-4">
{{job}}
</div>
<div class="col-md-4">
<button class="btn-primary btn-xs add" ng-click="showNext($event)" ng-hide="$last">Add</button>
<button class="btn-primary btn-xs delete" style="display: none;">Delete</button>
</div>
</div>
</div>
That works.
Now, each div has two buttons, Add and Delete. When I click add I want to hide the add button and delete button of the current row and open the next row. So I wrote,
$scope.showNext = function(evt) {
var elm = evt.target;
$(elm).hide();
$(elm).next().hide();
$(elm).closest("div.row").next().slideDown();
};
This is not working as ng-hide is overriding my slideDown. What is the angularjs way of doing it?
Also I would like the delete button only on the $last visible row && !first. How to find last visible row in ng-repeat?
Fiddle: https://jsfiddle.net/codeandcloud/u4penpxw/
You shouldn't manipulate the DOM with things like $(elm).hide();, you should use ng-class= to let Angular add classes that hide or show the elements. If you switch your ng-repeat to ng-repeat="job in jobs track by $index", you could write something like that in your showNext()-function:
$scope.showNext = function(index) {
$scope.currentJob = $scope.jobs[index]
}
and call it like ng-click="showNext($index) - of course you'd need to do some refactoring as well. But then you could write something like ng-class="{hidden: (job == currentJob}" to hide all buttons except in the current row.
There's a lot of good thoughts in this q&a: "Thinking in AngularJS" if I have a jQuery background?

ion-content won't resize when keyboard appears

I have an application with a chat functionality which works great, except for one part, when the keyboard appears, the ion-content won't resize to a proper height, so I am stuck when I want to scroll to the top and the header disappears completely. The view has a header, content and footer and what I want is the footer to appear above the keyboard and the content to resize so it fits between the header and the footer-bar. The view I have created is as followed:
<ion-view id="userMessagesView" cache-view="true" flow-init flow-name="imageTemp.imageTemp" ng-if="!inChatSettings">
<div class="loader-center" ng-if="!doneLoading">
<div class="loader">
<i class="icon ion-loading-c"></i>
</div>
</div>
<div class="loader-center" ng-if="errorLoading">
<div class="loader">{{'error_loading_messages'|translate}}</div>
</div>
<ion-content class="has-header has-footer" has-bouncing="true" delegate-handle="userMessageScroll" style="background:red;">
<ion-refresher pulling-text="{{'pull_load_earlier'|translate}}" on-refresh="loadMore()"></ion-refresher>
<div ng-repeat="message in messageThread.messages | orderBy : 'postDate'" class="message-wrapper">
<div class="chat-bubble" ng-class="{ false: 'left', true:'right'}[{{message.postedBy|isCurrentUser}}]">
<div class="message-detail">
<span class="bold">{{message.postedBy.name}}</span>
</div>
<div class="message" ng-bind-html="message.message | nl2br" autolinker></div>
<img ng-src="{{message.imageUrl}}" ng-if="message.imageUrl"/>
<small am-time-ago="message.postDate">{{message.postDate|timeago}}</small>
</div>
<div class="cf"></div>
</div>
</ion-content>
<ion-footer-bar class="bar-light message-footer">
<button class="button button-icon icon icon-upload" flow-btn flow-file-added="imageUploaded($file)" flow-name="imageTemp.imageUrlTemp"></button>
<label class="item-input-wrapper" for="newmessage">
<textarea focus-me="input.focusInput" id="newmessage" ng-model="input.message" value="" required minlength="1" maxlength="1500" msd-elastic></textarea>
</label>
<button class="button button-clear" type="submit" ng-disabled="!input.message || input.message === ''" ng-click="sendMessage()" translate="send"></button>
</ion-footer-bar>
</ion-view>
I tried adding the keyboard-attach attribute to the ion-footer-bar, but the footer only gets bigger when I add this. Plus the footer already stays on top of the keyboard, so it appears unneeded. I have the following situation, it also appears that when I type something, the view goes up a little more.
This is when the keyboard is shown:
This is when the keyboard is hidden:
Does any of you know how to resize the ion-content to a normal height when the keyboard appears?
I have tried some things and the problem seemed to disappear, yet I don't think the solution is the right one or if this is actually the thing what solved the issue. So if anyone got a better solution, please share. First thing I had to do was including the Ionic keyboard plugin to get events based on the keyboard.
Inside the CSS, I have added:
.message-footer { min-height: 44px; }
Inside my controller I added the following code:
$scope.$on('taResize', function (e, ta) {
if(!ta || !footerBar) return;
var taHeight = ta[0].offsetHeight + 10;
var newHeight = (taHeight < 44) ? 44 : taHeight;
scroller.style.bottom = newHeight + 'px';
footerBar.style.height = newHeight + 'px';
});

Get value from ng-repeat outside of ng-repeat

I got a header bar outside of ng-repeat:
<ion-header-bar class="headerView" ng-show="!hideAll">
<button id="shareImage" class="button button-icon icon ion-share" style="color:#fff" ng-click="shareImageTo({{originalImageSource}})"></button>
<button class="button button-outline button-light close-btn" ng-click="closeModal()">{{::actionLabel}}</button>
</ion-header-bar>
And a slidebox where images are shown:
<ion-slide ng-repeat="single in slides track by $index">
<div class="item item-image gallery-slide-view">
<img ng-src="{{single.original}}">
<input type="text" ng-model="originalImageSource" value="{{single.original}}">
</div>
</ion-slide>
{{single.original}} is an URL to an image. But this URL is not placed in the input field. It is shown when I´m deleting this ng-model statement.
If a user clicks the button #shareImage the ShareImageTo(URL) function is executed. But with an undefined value for {{originalImageSource}}.
Any thoughts on how i could pass the URL in {{single.original}} to this ShareImageTo() function?
With $ionicSlideBoxDelegate you can get the current slide index via currentIndex(). That enables you to get the URL by $scope.slides[$ionicSlideBoxDelegate.currentIndex()].original in your ShareImageTo()-method like that:
$scope.ShareImageTo = function() {
var URL = $scope.slides[$ionicSlideBoxDelegate.currentIndex()].original;
//your logic
};
Another approach would be to use ion-slide-box's directive on-slide-changed.
Template:
<ion-slide-box on-slide-changed="slideHasChanged($index)">
...
</ion-slide-box>
Controller:
$scope.slideHasChanged = function(index) {
$scope.originalImageSource = $scope.slides[index].original;
//.. some more logic
}
Just create a div that wrap around both your navbar and your slidebox, and place your ng-repeat in that div :)

[Angular JS]- Tabs Pane Example - Dynamic Add Tab

I have used the example from Angular JS Homepage and modified it to meet the requirements.
I have added the tabs info in a scope array and manipulate the data based in some conditions.
Issues:
I have attached an ng-bind on tabItem.title, so any change in the text box will update the title, but i want to limit the displaying of the title by 10 chars
When i create a new tab, i want that tab to be the selected one.
How can i select a tab based on some action taken (like on a click move from tab 1 to tab 2)
Fiddle: http://jsfiddle.net/austinnoronha/NWwcT
<br/><br/>
<div ng-cloak ng-app="TabsApp">
<div class="container" ng-controller="TabManagerCtrl">
<span class="label label-info label-ext" ng-click="tabManager.addTab()" style="cursor:pointer">Add a Tab</span><br/><br/>
<div>
<div tabs>
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title }}">
<p>{{ tabInfo.content }}</p>
<input type="text" ng-model="tabInfo.title" ng-change="tabManager.getTitle(tabInfo)">
</div>
</div>
</div>
<br/><br/><br/>
</div><!-- /container -->
</div> <!-- /container -->
</div> <!-- /app -->
that's strange...
The limitTo filter doesn't seem to work, but you can create a new one and change your line
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title }}">
by
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title | limit:10}}">
with
angularApp.filter('limit', function() {
return function (input, value) {
return input.substr(0,value);
};
});
For the select one, I think it doesn't work because you have to have access to the pane scope. One way to do it is to access to access the property from the pane when you create it. In the pane directive, just add :
if(scope.$parent.tabInfo.selected) tabsCtrl.select(scope);
just after the tabsCtrl.addPane(scope); line. But then you also have to change the tabs directive so that the line
$scope.select = function(pane) {
become
this.select = $scope.select = function(pane) {
For your 3rd question, I don't know how to do it in that scheme.
I would make the pane directive different, putting the select function out of the directive, and binding it directly to your tabManager object.
Like this : http://jsfiddle.net/NWwcT/2/
In this cas, you have the 3 requirements, and you can select the tab from ouside by calling tabManager.select(index)
