Open html on another tab on button click using Angularjs

I have a page in my AngularJS that has an edit button, I need to open the edit page on another tab when I click the edit button. Can it be possible using the angular way? I need to use the same controller to be able to access the data. How can I possible do this? Can someone please give me a sample?

Here's a fiddle to show opening the tab:
https://jsfiddle.net/e8g1m0xs/
I.e.:
angular.module('new_tab', [])
.controller('ExampleController', ['$scope', '$window', function($scope, $window) {
$scope.openTab = function() {
$window.open('https://www.google.com', '_blank');
};
}]);
<div ng-app="new_tab" ng-controller="ExampleController">
<button ng-click="openTab()">New Tab</button>
</div>
But in order to use the same controller for the new tab, and do something like pass information to it, you would have to implement a wildcard pattern into your angular router to pass along state information. I usually do things like that using UI Router. See the section titled URL Parameters.

Angular ui-router not loading external content on state change

I have started building a website using Angular, and have started to use ui-router along with ngAnimation for some sick animations! All was going well until I started adding external resources such as Facebook's Page Widget (https://developers.facebook.com/docs/plugins/page-plugin) and Google Maps API for some custom map styles.
The Issue
I have the Facebook widget on the home page, and it loads fine when you first access the URL as can be seen below (Have to block the name of client, totally not just bad design...):
Once I click on another page to load it in (using ui-view to dynamically bring in a view), for example contact view and go back to the home page (where the code is to display the widget), the widget will no longer load but will load the basic header tag that Facebook provide as can be seen below:
This also happens on the contact page when loading in Google Maps API. If I click on the contact page, there will just be a large white area on where the map should be, but if you had to actually refresh the page the map will load.
I am assuming that the issue is that the website is not able to send a request to either Facebook or Google when a view is loaded in, but can only happen when the page is actually refreshed or a new page load.
My Code
Okay so I'll explain the basics of how my application works along with code. I am rather new with Angular so if I have terrible code, please let me know.
Structure
This is a screen shot of my web apps structure. The main template file is index.html, and any view are within the views directory, which are loaded in using ui-router.
Main Angular applications code (app.js)
var app = angular.module('bmApp', ['ngAnimate', 'ui.router', 'ui.bootstrap'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('header', {
templateUrl: './assets/views/template.html',
})
.state('header.home', {
url: '/',
templateUrl: './assets/views/home.html',
controller: "HomeController"
})
.state('header.about', {
url: '/about',
templateUrl: './assets/views/about.html',
controller: "AboutController"
})
.state('header.work', {
url: '/work',
templateUrl: './assets/views/work.html',
controller: "WorkController"
})
.state('header.services', {
url: '/services',
templateUrl: './assets/views/services.html',
controller: "ServicesController"
})
.state('header.contact', {
url: '/contact',
templateUrl: './assets/views/contact.html',
controller: "ContactController"
});
$urlRouterProvider.otherwise('/'); //if no views are matched, just redirect back to home page.
})
I am using nested views to keep the header of the website static (not changing) and then loading in views under the header, with ngAnimate to make it look cool.
In my main template, index.html, I have a simple <div ui-view></div> to load in the view that is requested. I also have the required script to request Facebook's API just after the . My controllers do not actually currently have anything in them. I did have some vanilla JavaScript in some, but do not currently need it anymore. I also tried to wrap the code provided by Facebook in a function, and call it within the controller for the specific view but that just had the same results of having it within the body on the template (index.html) page.
Pulling my hair out at this, can't seem to find a solution. I hope I have explained my issue without missing out on anything. I appreciate any help you could give, would be so awesome.
Edit: I should have probably mentioned that my main template is index.html, I then inject the view in to /views/template.html AND THEN inject it into index.html. Not too sure if this is best practice, but felt like it would work well (I don't think that is the issue).

I will give you only half of an answer, but maybe it will point you to right direction. I also struggled with Google API in SPA application once. I had the same issue - after entering the contact page, a white box appeared instead of map. The solution turned out to be simple - I just needed to force map reload, when I entered contact sheet. This function was attached as onclick event to contact page link:
function reloadGoogleMap() {
if (counter == 0) {
document.getElementById('google-map').src += '';
counter++;
}
}
I used the counter to make sure it happens only once - you won't need it probably. With Angular, you might need to make sure the reload happens after element is rendered. Maybe a simple directive would work, however I didn't test that:
angular.module('your_directives_module')
.directive('mapLoaded', [mapLoadedDirective]);
function mapLoadedDirective() {
return {
restrict: 'A',
link: function (scope, elem, attrs) {
elem.on('load', function (event) {
// Force reload
elem.src += '';
});
}
};
}
It could be used like:
<!-- Div/iframe with google map -->
<div map-loaded></div>
Maybe Facebook API also has some simple way which you could use to force widget reload when the partial view is loaded, however I've never tried to use that with Angular.

Don't you have to wrap it in a $rootScope.$apply function in order to update your view?
$rootScope.$apply(function () {
// some code
});

AngularJS execute code when changing pages that use same controller

I have a PhoneGap app, that has multiple html pages.
I use one controller, called AppController, that loads the data for the startup screen and default pages.
I added a new page to the navigation bar, which, when clicked & opened should load up data from the server with a php call, so it should only make a php call, when the page is shown.
This page uses the same controller as the rest of the app.
I am really new to AngularJS, so I might've programmed it in a bad way, but the rest of the data for the home page is loaded in the appController like this
myApp.controller('AppController', function ($scope, $timeout, sharedProperties) {
$scope.items= {};
$scope.items[item1] = {....} //LOADING UP the items collection
}
How can I hook up an "onload" event or something, that would only fire when the page is shown?

There are so many ways you could do that, one of them:
// inside your controller
angular.element(document).ready(function () {
// your code
});
another one:
<div ng-controller="myCtrl" ng-init="someinitfunc()"></div>

How about using ng-init() directive on your next page ?

Angular UI Router: Setting autoscroll on header view does not scroll to top

TL;DR: With Angular UI Router, is it possible to autoscroll to a view of the same state that the template displaying it belongs to?
The Setup
I have an Angular 1.4.1 app, using UI Router 0.2.15 and Angular Material 0.10.0.
Example Plunk
There is a parent state called website and three child states: home, foo and bar.
The parent state has a wrapper view, which is displayed via the <ui-view> tag in index.html. It also has two other views, header#website and footer#website, which it displays via the wrapper view template.
Each of the three child states has a main view, which is displayed via the parent state's wrapper view template.
What I Expect
In the parent state's wrapper view template, when I set autoscroll="true" on the ui-view tag for the header#website view, I expect that the page will scroll to the top whenever the state changes. See the accepted answer of this SO question.
What Is Happening
When any of the ui-sref links in the footer is clicked, the page does not scroll to the top.
What I've Tried
If I put autoscroll="true" on the ui-view tag for the main view, it works as expected. This is not what I want, however, because the header is hidden from view even when you navigate to a state from the address bar.
What I Suspect
I think the problem has to do with the fact that header#website is a view that belongs to the website state, and that autoscroll only works for views that normally are displayed on the current template. In other words, normally the header view would be displayed via index.html, not wrapper.html.
The Question
Is my suspicion above correct? Do I need to refactor, or is there a way to make this work as is?
Thanks in advance!

Though I don't advocate DOM manipulation outside of a directive, a quick and dirty solution would be to add a scrollTo method in a .run block of your top level module definition, for ex:
.run(function ($window, $rootScope) {
$rootScope.$on('$viewContentLoaded', function () {
var interval = setInterval(function () {
if (document.readyState == "complete") {
window.scrollTo(0, 0);
clearInterval(interval);
}
}, 1);
});
})

I tried using the $anchorScroll() method of ui-router, but since your links are at the bottom of the page, thats where the page scrolls to, so you dont actually notice it doing anything.

AngularJS $stateParams when using reloadOnSearch:false

I have a page in my application which uses a search so i have added the "realoadOnSearch:false" which works perfectly
The problem I have is when navigating to the same state with a different stateParam:
when I navigate to #/category/20/ from any other page it works fine... i then have a link on that page to #/category/3 (the parent category for 20) and the URL updates, however the content does not (no console errors)
app.js (main application)
.state('category', {
url: '/category/:categoryId/',
templateUrl: '/Home/Category',
controller: 'categoryCtrl',
reloadOnSearch: false
})
I have tried adding target="_self" to force page reload and it does not work
I have also tried to watch $stateParams for changes and there is nothing
Clicking the link to #/category/3 from #/category/20 (and vice versa) should navigate to the new page and reload the data, where search should NOT reload the page (latter works but not the former)
The URL is prefered to be a ng-href rather than ng-click as it is managed by the root controller
EDIT:
I did not find a direct solution, however i just disabled the reloadOnSearch and my sorting buttons still work so this works for me for now as a solution.

The problem is that reloadOnSearch doesn't do what you think it does; it's actually more like reloadOnStateParams. Setting it to false prevents you from making state changes where only the stateParams change, which is what you're doing here (going from #/category/3 to #/category/20).
You can see this documented on the UI router issues page: https://github.com/angular-ui/ui-router/issues/1079
There's some workarounds in there but none of them are great. You are probably best off using an ng-click that forces a reload manually, something like this:
$state.transitionTo($state.current, $stateParams, {
reload: true,
inherit: false,
notify: true
});
