I've implemented a popover with number keys on it using this library https://github.com/alvarowolfx/ng-keypad.
When I click on an input field, the popover appears. But, sometimes the position of content of popover is not correct.
Can you please help me.
Here is my html:
<script id="keypad-popover.html" type="text/ng-template">
<ion-popover-view class="aiv-keypad">
<ion-content overflow-scroll=false>
<div class="ios">
<ng-keypad on-key-pressed='onKeyPressed'>
<ng-key ng-repeat='key in aivkeys' ng-key-data='key' ng-key-type='keypad.type'>{{key}}</ng-key>
<!--<ng-key ng-key-type='keypad.type' ng-key-data="keypad.data">{{keypad.data}}</ng-key>-->
</ng-keypad>
</div>
</ion-content>
</ion-popover-view>
</script>
In controller,
$ionicPopover.fromTemplateUrl('keypad-popover.html', {
scope: $scope,
backdropClickToClose:false
}).then(function(popover) {
$scope.keypad_popover = popover;
});
Expected,
Sometimes, this problem occurs,
While the problem could be described as overflow scrolling, the overflow-scroll=false attribute you're using on <ion-content> means you are explicitly using Ionic scroll, which is to use transform3d() in CSS to implement scrolling. Usually overflow-scroll=false is the default.
If you'd turn overflow-scroll=true the element would use "traditional" overflow-y: auto CSS rule instead of transform3d(). With popovers, this is usually enough to fix the problem you describe.
If not—you can disable element's scrolling altogether with scroll=false attribute.

I've a view with textangular as an element. On Android(I tested), if the keyboard is opened, the view is not scrolling up to prevent the editor from getting behind the keyboard.
I installed the Keyboard plugin com.ionic.keyboard.
This is the structure of the page:
<ion-view id="newblogview">
<ion-nav-buttons side="left">
...
</ion-nav-buttons>
<ion-content scroll="true" overflow-scroll="true" class="has-header" delegate-handle="mainScroll">
<iframe data-tap-disabled="true" style="width: 100%; min-height: 100%" src="./templates/blog/html/blog-editor.html" name="blogeditor" id="blogeditor"></iframe>
</ion-content>
</ion-view>
it's not moving up when the keyboard is opened by focusing on the input.
I've tried android:windowSoftInputMode="adjustPan" and also "adjustResize"
And also I've tried native.keyboardshow event to call $ionicScrollDelegate.scrollBottom(true);
I think we've Keyboard attach directive for footer, but I can't place text editor in the footer.
Does ionic framework support adjusting ion content to keyboard show/hide? is this feature is not supported yet in framework or am I missing something.
This question is similar to another thread, but there is no accepted answer.
Please help.

You can add this to your html component
<div delegate-handle="toThisPosition" ng-click="GoHere()"> </div>
and adding this to the ng-click method GoHere() in your controller:
GoHere() {
$ionicScrollDelegate.$getByHandle('toThisPosition').scrollBottom(true);
}
I would like to add an iframe to a page when certain links are clicked and remove it when other mouse events happen on the page. From what I can see, it seems that using an AngularJS directive would be the best way to do this. What I'm not sure about is what is the best way to format the directive. I'm thinking of making the directive at the attribute level...something like this:
<div myIframeDirective></div>
What I'm not sure of is the best way of removing/adding the directive contents (an iframe and a header above it) when various click events happen on the main page. Not looking for anyone to write the code for me...just looking for examples of how this can be best accomplished.
You should be using ng-if.
<iframe src="http://www.example.com/" ng-if="showIframe"></iframe>
<button ng-click="showIframe = !showIframe">Click me to show/hide the iframe</button>
Here's a working example:
var app = angular.module('app', []);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<iframe src="http://www.example.com/" ng-if="showIframe"></iframe>
<button ng-click="showIframe = !showIframe">Click me to show/hide the iframe</button>
</div>
In Angular, ng-if will remove the iframe from the DOM if it is false.
This means the URL will NOT be requested until ng-if is true.
<iframe ng-if="frameDisplayed" ng-src="{{src}}"></iframe>
And use the link
Toggle
Then in your controller, you can control what your iframe display:
$scope.src = 'https://angularjs.org';

What I would like to do is closing the popover window after clicking somewhere outside. I know that there were similar questions but I would like to know how to do that in Angular. Problem is, my popover is located inside script tag.
<script type="text/ng-template" id="templateId.html">
This is the content of the template {{name}}
</script>
In bootstrap's documentation they have an example of a 'dismissable' popover.
The trick is to add trigger: 'focus' to your popover options. You then need to change your element to a 'focusable' element (in this example i have used a button)
Here is my fork of your example.
PS. it is worth mentioning that not all elements are natively 'focusable'. You can make sure that an element can become focusable, but adding the attribute tabindex (eg. tabindex="-1").
Looks like I have found an answer to my question. All we need to do is to apply this solution: How to dismiss a Twitter Bootstrap popover by clicking outside? to directive responsible for showing popover. What's more, we need to add data-toggle="popover" to our button.
And, surprisingly, it works very well.
If you want it to work seamlessly on any kind of elements without having to use any external code nor weird things, all you have to do is add this 2 attributes to your markup: tabindex="0" to make the element focusable, and popover-trigger="focus" to make it dismiss the popup once you click off.
Example with <i> tag which is not focusable:
<i popover-html="someModelWhichContainsMarkup" popover-trigger="focus"
tabindex="0" class="fa fa-question-circle"></i>
You can use following code:
<div ng-app="Module">
<div ng-controller="formController">
<button uib-popover-template="dynamicPopover.templateUrl" popover-trigger="focus" popover-placement="left" type="button" class="btn btn-default">Popover With Template</button>
<script type="text/ng-template" id="myPopoverTemplate.html">
<div>
<span>prasad!!</span>
</div>
</script>
</div>
</div>
In Script :
<script type="text/javascript">
var app = angular.module("Module", ['ui.bootstrap']);
app.controller("formController", ['$scope', function ($scope) {
$scope.dynamicPopover = {
templateUrl: 'myPopoverTemplate.html'
};
}]);
</script>
Works for me, add this attribute to the tag which is calling/opening the popup, DON'T MISS THE SINGLE QUOTES AROUND outsideClick
popover-trigger="'outsideClick'"
This opens only one popover and closes upon clicking outside of popover
popover-trigger="outsideClick"
I used button click to change the route to the next page. Angular JS retain the scroll position and doesn't scroll to the top of the ng-view.
1. Disabling $anchorScroll doesn't work
2. Using window scroll to doesn't work
$rootScope.on("$routeChangeSuccess", function(){
window.scrollTo(0,90);
})
However, to keep the fix header on iPad, the following window scroll works.
$(document).on('blur', 'input, textarea', function() {
setTimeout(function() {
window.scrollTo(document.body.scrollLeft,document.body.scrollTop);
}, 0);
});
Any suggestions? How to clear the stored scroll positions by angualar js view?
What you want is not disable anchorscroll, but enable it. You can achieve what you want using the following code:
<div data-ng-view data-autoscroll="true"></div>
or:
<div data-ng-view data-autoscroll></div>
as pointed in the AngularJS docs.
Minor update to #Rafael's answer.
Since Angular 1.3.14 you can use simpler syntax to enable autoscroll to the top when switching views with ngView:
<div ngView autoscroll></div>
Angular Docs
Have you tried setting autoscroll to false on your ng-view element?
<div data-ng-view data-autoscroll="false"></div>
I'm using an AngularJS-based library called "Ionic" (http://ionicframework.com/).
This seems simple, but it isn't working for me.
In one of my views, I have the following
<view title="content.title">
<content has-header="true" padding="true">
<p>{{ content.description }}</p>
<p><a class="button button-small icon ion-arrow-left-b" href="#/tab/pets"> Back to home</a></p>
</content>
</view>
In the controller for the above view, I have
angular.module('App', []).controller('DetailCtrl', function($scope, $stateParams, MyService) {
MyService.get($stateParams.petId).then(function(content) {
$scope.content = content[0];
console.log($scope.content.title); // this works!
});
});
The data for this view is loaded via a simple HTTP GET service (called MyService).
The problem is that when I view this page,
<view title="content.title">
Doesn't display the title. It's just a blank. According to the Ionic documentation (http://ionicframework.com/docs/angularjs/controllers/view-state/), I think I'm doing the right thing.
It's strange that {{content.description}} part works, but content.title doesn't work?
Also, is it because I'm loading the content dynamically (via HTTP GET)?
By using the ion-nav-title directive (available since Ionic beta 14), the binding seems to work correctly.
Rather than
<ion-view title="{{content.title}}">
....
Do this
<ion-view>
<ion-nav-title>{{content.title}}</ion-nav-title>
...
Works a treat.
A solution for newer versions of Ionic is to use the <ion-nav-title> element rather than the view-title property. Just bind your dynamic title inside the content of the <ion-nav-title> using curly brace syntax. Example:
<ion-view>
<ion-nav-title>
{{myViewTitle}}
</ion-nav-title>
<ion-content>
<!-- content -->
</ion-content>
</ion-view>
Here's a working example of how to accomplish this in Ionic. Open the menu, then click "About". When the "About" page transitions, you will see the title that was resolved.
As Florian noted, you need to use a service and resolve to get the desired effect. You then inject the returned result into the controller. There are some down sides to this. The state provider will not change the route until the promise is resolved. This means there may be a noticeable lag in the time the user tries to change location and the time it actually occurs.

If you look at ionic view directive source on github, it's not watching on title attributes which means it won't update your view when you set a new value.
The directive is processed before you receive the answer from server and you fill $scope.content.title.
You should indeed use a promise in your service and call it in a resolver. That or submit a pull request to ionic.
I was encountering the same problem and was able to solve it by wrapping my title in double-curlies.
<ion-view title="{{ page.title }}">
I should note that my page.title is being set statically by my controller rather than from a promise.
I had a very similar issue where the title wouldn't update until i switched pages a couple of times. If i bound the title another place inside the page, it would update right away. I finally found in the ionic docs that parts of those pages are cached. This is described here http://ionicframework.com/docs/api/directive/ionNavView/
To solve my issue, I turned caching off for the view with the dynamic title:
<ion-view cache-view="false" view-title="{{title}}">
...
</ion-view>
I got this to work on older versions of Ionic using the <ion-view title={{myTitle}}> solution (as per plong0's answer).
I had to change to <ion-view view-title= in the more recent versions. However using beta-14 it's showing blank titles again.
The nearest I've got to a solution is to use $ionicNavBarDelegate.title(myTitle) directly from the controller. When I run this it shows the title briefly and a moment later blanks it.
Very frustrating.
It's the first time that I worked with dynamic title in Ionic 1.7 and I run into this problem. So I solved using $ionicNavBarDelegate.title(') from the controller, as mentioned Kevin Gurden. But additionally, I used cache-view="false".
View:
<ion-view cache-view="false"></ion-view>
Controller:
angular
.module('app', [])
.controller('DemoCtrl', DemoCtrl);
DemoCtrl.$inject = ['$ionicNavBarDelegate'];
function DemoCtrl($ionicNavBarDelegate) {
$ionicNavBarDelegate.title('Demo View');
}
Use ion-nav-title instead of the directive view-title.
see http://ionicframework.com/docs/api/directive/ionNavTitle/
This is the true solution: data bind the ion-nav-title directive
<ion-view>
<ion-nav-title ng-bind="content.title"></ion-nav-title>
<ion-content has-header="true" padding="true">
<p>{{ content.description }}</p>
<p><a class="button button-small icon ion-arrow-left-b" href="#/tab/pets"> Back to home</a></p>
</ion-content>
</ion-view>
http://ionicframework.com/docs/api/directive/ionNavTitle/
I m using ionic v1.3.3 with side menus based template. I tried all solutions given above but no luck.
I used the delegate from $ionicNavBarDelegate:
http://ionicframework.com/docs/v1/api/service/$ionicNavBarDelegate/
I created a function inside my angular controller to set the title :
angular.module('app.controllers').controller('contributionsCtrl', contributionsCtrl);
function contributionsCtrl($scope, $ionicNavBarDelegate) {
vm.setNavTitle = setNavTitle;
function setNavTitle() {
var title = "<span class='smc_color'> <i class='icon ion-images'></i> Your Title </span>"
$ionicNavBarDelegate.title(title);
}
}
Then inside my html just called the function vm.setNavTitle
<ion-view overflow-scroll=true ng-init="vm.setNavTitle()">
<ion-content></ion-content>
</ion-view>
<ion-view> <ion-nav-title>{{ result.title }}</ion-nav-title>
This work for me
