Dynamic list for Ionic App using Angular JS in two views

I have a Ionic app with Angular JS. I have a Dynamic checkbox list which is called from an array in app.js. I have it so that when a user clicks on a checkbox, the list above gets updated with their choice, what I want is for the choice to get put into another view not another div i.e tab 1 = List, tab - 2 = choices. The code is:
$scope.myList = [
{name:'Choice one'},
{name:'Choice two)'}
];
$scope.myChoices = [];
$scope.stateChanged = function(checked,indx){
var item = $scope.myList[indx];
if(checked){
$scope.myChoices.push(item);
}else{
var index = $scope.myChoices.indexOf(item);
$scope.myChoices.splice(index,1);
}
}
html:
<div>
<div class="item item-dark item-icon-right">
My Choices
</div>
<ul class="list" >
<li class="item" ng-repeat='item in myChoices'>
<p>{{item.name}}</p>
</li>
</ul>
<div class="item item-dark item-icon-right">
University list
</div>
<div class="item item-input-inset">
<label class="item-input-wrapper">
<i class="icon ion-ios-search placeholder-icon"></i>
<input type="text" placeholder="Search" ng-model="search">
</label>
<button class="button ion-close-circled input-button button-small"
ng-click="search = ''" ng-show="search.length">
Clear search
</button>
</div>
<ul class="list" >
<li class="item item-checkbox" ng-repeat='item in myList | filter: search'>
<label class="checkbox">
<input type="checkbox" ng-model="checked" ng-change='stateChanged(checked,$index)'>
</label>
<p>{{item.name}}</p>
</li>
</ul>
</div>
Tabs:
<ion-tabs class="tabs-icon-top tabs-dark">
<ion-tab title ="List" icon-on="home" icon-off="home" href="#/tab/list">
<ion-nav-view name="list-tab"></ion-nav-view></ion-tab>
<ion-tab title ="My choices" icon-on="choices" icon-off="choices" href="#/tab/choice">
<ion-nav-view name="choice-tab"></ion-nav-view></ion-tab>
</ion-tabs>

When you are trying to send data across multiple views, the easiest way is to store the data in a factory variable. Whenever you need the data, you can get it from the factory with a simple get.
// This module can be in its own javascript file
angular.module('choicesFactory', [])
.factory('choicesFactory', function() {
var choicesStored = [];
return {
storeChoices: function(choices) {
choicesStored = choices;
return;
},
getChoices: function() {
return choicesStored;
},
};
});
Now, to implement this bit of code, all you have to do is include the javascript file after your inclusion of angularjs in your index.html and add choicesFactory to your app dependencies.
When you call the function from your controller, you can say:
.controller('choicesController', [
'$scope',
'$state',
'choicesFactory'
function($scope, $state, choicesFactory) {
// An example with getting the choices
var choices = choicesFactory.getChoices()
}]);
If this doesn't quite make sense, I made a codepen example app that demonstrates all the pieces working together.

ionic collection-repeat working navigation not working on click

I am new to ionic and angular.js. I download this ionic collection repeat and navigation example from http://codepen.io/ionic/pen/mypxez. The initial example was working perfect with single index.html and index.js files. I tried to separate the code in controller, service, app.js and in the HTML files. I can see the collections but I am not able to see the details and navigate it. Here is the HTML file to show all collection which works:
<ion-view title="Home">
<ion-header-bar class="bar-subheader item-input-inset">
<label class="item-input-wrapper">
<i class="icon ion-ios7-search placeholder-icon"></i>
<input type="search" placeholder="Search" ng-model="filter">
</label>
</ion-header-bar>
<ion-nav-buttons side="right">
<a class="button" ng-click="scrollBottom()">
Scroll To Bottom
</a>
</ion-nav-buttons>
<ion-content>
<div class="list">
<a class="item my-item item-thumbnail-left"
collection-repeat="pet in pets | filter:filter"
collection-item-height="90" collection-item-width="'100%'"
ui-sref="tab.detail({petsId: pet.id })">
<img ng-src="http://placekitten.com/60/{{55 + ($index % 10)}}">
<h2>{{pet.firstName}}</h2>
<p>{{pet.id}}</p>
</a>
</div>
</ion-content>
</ion-view>
Here is the code of app.js:
.state('tab.dash', {
url: '/dash',
views: {
'tab-dash': {
templateUrl: 'templates/tab-dash.html',
controller: 'DashCtrl'
}
}
})
.state('tab.detail', {
url: "/detail/:petsId",
views: {
'main': {
controller:'DetailCtrl',
templateUrl: "templates/question-detail.html"
}
}
})
Here is the code of the controller which never get called:
.controller('DetailCtrl', function($scope, $stateParams, PetService) {
$scope.pet = PetService.get($stateParams.petsId);
})
...and the question-detail.html code:
<ion-view title="{{pet.id}}">
<ion-content class="padding">
{{pet.id}}
{{pet.firstName}}
</ion-content>
</ion-view>
I can view the collection and can search but I am not able to see the details by clicking them. I can see the url (http://localhost:8100/#/tab/detail/2) if i click on item 2 but i am not able to see the question- detail.html page.

Considering you are very new to this framework, or angularJS itself. I am just going to answer the question without saying anything else, but for future, please go through docs first.
<ion-view title="{{pet.id}}">
<ion-content class="padding">
{{pet.id}}
{{pet.firstName}}
</ion-content>
</ion-view>

Thanks karan for your prompt answer.. I changed two things and the
code is working now:
the html file where i declared the anchor tag. I changed the ui-sref
to href:
<div class="list">
<a class="item my-item item-thumbnail-left"
collection-repeat="pet in pets | filter:filter"
collection-item-height="90"
collection-item-width="'100%'" href="#/tab/detail/{{pet.id}}">
<img ng-src="http://placekitten.com/60/{{55 + ($index % 10)}}">
<h2>{{pet.firstName}}</h2>
<p>{{pet.id}}</p>
</a>
</div>
my app.js file
.state('tab.detail', {
url: '/detail/:petsId',
views: {
'tab-chats': {
templateUrl: 'templates/question-detail.html',
controller:'DetailCtrl'
}
}
})

Ionic infinite scrolling, only scrolls when navigated away and back to page

I have a ionic content with a ionic list in it.
Here is my HTML:
<ion-content>
<ion-view>
<ion-list >
<div class='myCard' ng-repeat="maanta in maanta| limitTo : limit track by $index">
<a class='normala' href="#/tab/dash/{{maanta.id}}">
<div class='cardHeader item-text-wrap'>
{{maanta.title}}
</div>
<hr class='divi'>
<div class='cardDivider item-text-wrap'>
{{maanta.source}} - {{maanta.pub_date}}
</div>
<hr class='divi'>
<div class='cardBody item-text-wrap'>
{{maanta.summery}}
</div>
</a>
</div> </ion-list>
<ion-infinite-scroll ng-if="!noMoreItemsAvailable" on-infinite="loadMore()" distance="1%"></ion-infinite-scroll>
</ion-content>
</ion-view>
Here is my JS:
$scope.limit = 10;
$scope.loadMore = function() {
$scope.limit +=10
if ( $scope.maanta.length <$scope.limit) {
$scope.noMoreItemsAvailable = true;
}
$scope.$broadcast('scroll.infiniteScrollComplete');
};
The problem
When I first land on the page the infinite scrolling doesn't change limit for my ng-repeat. When I navigate away to another page and come back the infinite loop works as expected.

Check out your HTML. There's a mistake in the tag sequence :
<ion-content>
<ion-list >
<div class='myCard' ng-repeat="maanta in maanta| limitTo : limit track by $index">
<a class='normala' href="#/tab/dash/{{maanta.id}}">
<div class='cardHeader item-text-wrap'>
{{maanta.title}}
</div>
<hr class='divi'>
<div class='cardDivider item-text-wrap'>
{{maanta.source}} - {{maanta.pub_date}}
</div>
<hr class='divi'>
<div class='cardBody item-text-wrap'>
{{maanta.summery}}
</div>
</a>
</div> </ion-list>
<ion-infinite-scroll ng-if="!noMoreItemsAvailable" on-infinite="loadMore()" distance="1%"></ion-infinite-scroll>
</ion-content>
The tag <ion-view> was not required as such.

I think you should reconsider your approach and try to push the new content to your view.
The key is pushing the new content.
Fore example (from user DILIP on codepen:)
<ion-infinite-scroll distance="2"
on-infinite="loadMoreData()"
ng-if="!moredata" >
</ion-infinite-scroll>
var app = angular.module("ionicInfiniteScrollApp",['ionic']);
app.controller("InfiniteAppCntrl",function($scope)
{
$scope.moredata = false;
$scope.loadMoreData=function()
{
$scope.items.push({id: $scope.items.length});
if($scope.items.length==100)
{
$scope.moredata=true;
}
$scope.$broadcast('scroll.infiniteScrollComplete');
};
$scope.items=[];
});
Here's the link to the codepen:

Ember navbar UI condition based on currentPath

I must not be doing something right. I have the following:
application.hbs
{{#view App.NavbarView}}{{/view}}
{{outlet}}
with the following template for Navbar
_navbar.hbs
<div class="toolbar">
<div class="row">
<div class="absolute top-left">
<button {{action "back"}} class="btn passive back"><i class="fa fa-play"></i></button>
</div>
{{#if hasTabs}}
<div class="small-centered columns">
<div class="tabs">
<ul>
{{#link-to 'stories' tagName="li" class="tab"}}<i class="fa fa-book"></i> Stories{{/link-to}}
{{#link-to 'mylevels' tagName="li" class="tab"}}<i class="fa fa-user"></i> My Levels{{/link-to}}
{{#link-to 'arcade.index' tagName="li" class="tab"}}<i class="fa fa-gamepad"></i> Arcade{{/link-to}}
</ul>
</div>
</div>
{{else}}
<div class="small-6 small-offset-3 columns">
<h2 class="title">{{ pageTitle App.currentPath }}</h2>
</div>
{{/if}}
{{#if currentUser.userName}}
<div class="absolute top-right">
<span class="user-hello">Welcome Back, <strong>{{ currentUser.userName }}</strong></span>
<button {{action "transitionAccount" currentUser._id}} class="square logged-in"><i class="fa fa-user"></i></button>
</div>
{{ else }}
<div class="absolute top-right">
<button {{action "transitionLogin"}} class="square logged-out"><i class="fa fa-user"></i></button>
</div>
{{/if}}
</div>
</div>
So all it is is a typical fixed navbar and in the middle of it I display what page you are on, if you happen to be on a page that has tabbed content, I show a tab container instead.
So I'm just using this.get('currentPath') in my App controller and comparing it against a group of route names to trigger true/false (I need an observer so it looks at the route change since the Navbar is in inline view at the Application level).
app.js
App.ApplicationController = Ember.ObjectController.extend({
updateCurrentPath: function() {
App.set('currentPath', this.get('currentPath'));
}.observes('currentPath'),
tabs: function() {
var route = this.get('currentPath'),
group = ['arcade.index', 'mylevels', 'stories', 'arcade', 'arcade.loading'];
console.log("ROUTE: ", route);
var tabs = group.indexOf(route) > -1 ? true : false;
return tabs;
}.observes('currentPath'),
// no idea what to do here
hasTabs: function() {
this.tabs();
}.property('tabs')
});
So, basically, no matter what, the tab UI is showing up, but I only want it to show up if that tabs observer is true. With some debugging I'm getting all the console output I would expect but I tried just doing {{#if tabs}} (just using the observer directly) and that always fires true (always shows the tabs UI). I assumed that's because it was an observer and not an actual controller property I could use in my template, so I tried just setting the hasTabs property and referencing the observer, but that doesn't seem to work. I realize I am fundamentally not understanding how this should work. Any thoughts?

If I understand your question correctly you should be able to just change your code to this (renamed tabs to hasTabs, removed previous hasTabs function. Changed from observes currentPath to be property of current path, removed the tabs variable assignment and replaced with the return, reduced the boolean conditional to the simple comparison operator). This is what I'd do, anyway. :) H2H
hasTabs: function() {
var route = this.get('currentPath'),
group = ['arcade.index', 'mylevels', 'stories', 'arcade', 'arcade.loading'];
return group.indexOf(route) > -1;
}.property('currentPath')
