Strange behavior using multiple transclude component in Angularjs 1.6.1

I've a strange behavior using multiple transclude component in Angularjs:
changes in first slot model no visible in controller.
<div ng-app="myApp" ng-controller="testController">
<script type="text/ng-template" id="component-template.html">
<div style="color:red;" ng-transclude="heading">
</div>
<div style="color:blue;" ng-transclude="body">
</div>
</script>
Example1
<input ng-model="example1Model"/>
<test-component>
<panel-heading>
Example2
<input ng-model="example2Model"/>
</panel-heading>
<panel-body>
Example1Result:{{example1Model}}<br/>
Example2Result:{{example2Model}}
</panel-body>
</test-component>
</div>
<script>
angular.module("myApp", [])
.controller("testController", function ($scope, $location) {
})
.component("testComponent", {
templateUrl: "component-template.html",
transclude: {
heading: "panelHeading",
body: "panelBody"
},
controller: function ($scope, $element, $attrs) {
this.$doCheck = function () {
//do anything
}
}
});
</script>
Now if you try to test it in this JSfiddle:https://jsfiddle.net/Lpveophe/1/
Why binding model example2Model did not working?
However example1Model binding model working correctly.

You need to use . in ng-model to make it work. For better understand of scope, please go through this article: https://github.com/angular/angular.js/wiki/Understanding-Scopes
To make it work, replace example2Model with o.example2Model everywhere and change your controller to:
.controller("testController", function ($scope, $location) {
$scope.o = {};
$scope.o.example2Model = '';
})

Modal in Angular does not work. Unhandled rejection {}

I want to create a modal (dialog). I have followed examples on official bootstrap documentation but I stuck. When I am trying to create modal I receive an error
angular.min.js:122 Possibly unhandled rejection: {}
mainController:
angular
.module('app')
.controller('tlmController', function($scope, $http, $timeout, $uibModal, DTOptionsBuilder, DataLoader, TestLines) {
$scope.openTestLineDetails = function(id) {
var modalInstance = $uibModal.open({
size: 'lg',
controller: 'testlineDetailsController',
templateUrl: 'app/client/layout/testlinedetails.tpl.html',
resolve: {
testLineId: function() {
return id;
}
}
});
};
})
and TestlineDetailsController:
angular
.module('app')
.controller('testlineDetailsController', function($scope, $modalInstance, testLineId) {
});
What is wrong with this code? I am using $uibModal ($modal service does not exist) in main controller. When I replace $modalInstance by $uibModalInstance I receive an error too (service $uibModalInstance does not exist), so I have to use $uibModal with $modalInstance. Strage but true.

you can write below code in app.config
app.config(['$qProvider', function ($qProvider) {
$qProvider.errorOnUnhandledRejections(false);
}]);

First of all, check your modal controller script is appended to the main HTML file and if its appended(appears) in the browser (In Chrome, open web developer tools with F12 keyboard button then open the "Elements" tab button) (This is in case you are using some scaffolding tool like generator-angular from Yeoman's team, remember to clear cache in order to get the latest update from your code), because I had the same problem :( and I was reviewing constantly what was wrong with my code then I found out that the browser was not appending the latest script I made (Modal controller), so my code was like yours, but taking your code example:
<!-- In your index.html file, check for this script being appended in your browser -->
<script src="testlineDetailsController.js"></script>
//In your parent controller
angular
.module('app')
.controller('tlmController', function($scope, $http, $timeout, $uibModal, DTOptionsBuilder, DataLoader, TestLines) {
$scope.openTestLineDetails = function(id) {
var modalInstance = $uibModal.open({
size: 'lg',
controller: 'testlineDetailsController',
templateUrl: 'app/client/layout/testlinedetails.tpl.html',
resolve: {
testLineId: function() {
return id;
}
}
});
};
})
Secondly, make sure you are implementing at least one method from the modal instance service in the modal controller: EDIT: (This is optional, you can hide the modal using the backdrop property from the modal option object)
//In your modal controller
angular.module('app').
controller('testlineDetailsController', function ($scope, $uibModalInstance, testLineId) {
//In case you have the ok and cancel buttons in your modal template
$scope.id = testLineId;
$scope.ok = function () {
$uibModalInstance.close();
};
$scope.cancel = function () {
$uibModalInstance.dismiss('cancel');
};
});
After this, your app should be working.
Now, there is another alternative to get this issue solved, you can directly write the controller function in the property of the modal options object:
//In your parent controller
angular
.module('app')
.controller('tlmController', function($scope, $http, $timeout, $uibModal, DTOptionsBuilder, DataLoader, TestLines) {
$scope.openTestLineDetails = function(id) {
var modalInstance = $uibModal.open({
size: 'lg',
//write an anonymous function instead of naming the controller name.
controller: function ($scope, $uibModalInstance, testLineId) {
$scope.id = testLineId;
$scope.ok = function () {
$uibModalInstance.close();
};
$scope.cancel = function () {
$uibModalInstance.dismiss('cancel');
};
},
templateUrl: 'app/client/layout/testlinedetails.tpl.html',
resolve: {
testLineId: function() {
return id;
}
}
});
};
})
This alternative should work also in your app. So I hope this explanation helps you to solve the issue you have.

Passing Parameter to Angular Factory from controller

I couldn't pass the parameter from angular controller to factory. Can any one help me on this? It works without passing parameter but when I pass it it's not.
var app = angular.module('employee', ['ui.grid', 'ui.grid.saveState', 'ui.grid.selection', 'ui.grid.cellNav', 'ui.grid.resizeColumns', 'ui.grid.moveColumns', 'ui.grid.pinning', 'ui.bootstrap', 'ui.grid.autoResize','ui.grid.pagination']);
app.controller('EmpCtrl', ['$scope', '$http', '$interval', '$modal', '$log', 'gridService', function ($scope, $http, $interval, $modal, $log, gridService) {
$scope.LoadNextPage = gridService.LoadNextPage("5");
}]);
var gridService = function ($http, $rootScope) {
return {
LoadNextPage: function (hh) {
alert(hh);
},
gridOptions:gridOptions
};
};
app.factory('gridService', ['$http', '$rootScope', gridService]);
And this is how I use it in the view
<span id="pcNext"
class="glyphicon glyphicon-step-forward"
ng-click="LoadNextPage()">
</span>

The problem is in your controller:
$scope.LoadNextPage = gridService.LoadNextPage("5");
This means that your LoadNextPage is not a function but rather a result of the call to a function in your service. Which btw doesn't return anything but rather just displays an alert. But in your view, you're using LoadNextPage as a function call...
Change it to this so your controller's LoadNextPage will be a function that you can call from the view.
$scope.LoadNextPage = gridService.LoadNextPage;
and in your view:
<span id="pcNext"
class="glyphicon glyphicon-step-forward"
ng-click="LoadNextPage(5)">
</span>
This should work.
Note: I suspect that your gridOptions are defined somewhere outside of scope of your code that you provided in the question so that it doesn't throw and error because of the missing (likely) object. So I considered this a typo in your code and not the actual problem.
Don't want params in your view?
No problem. You can either create a wrapper function or bind it to specific parameters in your code:
// wrap
$scope.LoadNextPage = function() {
return gridService.LoadNextPage("5");
};
// bind
$scope.LoadNextPage = gridService.LoadNextPage.bind(this, 5);
Or bake the number in your service...

Issue here is gridOptions:gridOptions is not defined which throws error.
Remove ,gridOptions:gridOptions from factory.
Check snippet for working code and compare with your code.
var app = angular.module('employee', []);
app.controller('EmpCtrl', ['$scope', 'gridService', function ($scope, gridService) {
$scope.clickMe = function() {
$scope.LoadNextPage = gridService.LoadNextPage("5");
}
}]);
var gridService = function() {
return {
LoadNextPage: function (hh) {
alert(hh);
}
};
};
app.factory('gridService', ['$http', '$rootScope', gridService]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="employee" ng-controller="EmpCtrl">
<button ng-click="clickMe()">Button</button>
</div>

you not defined gridOptions function see this link:
angular.module("myApp", []).controller("myCon", function($scope, $interval, gridService){
$scope.LoadNextPage = gridService.LoadNextPage("5");
}).factory('gridService', ['$http', '$rootScope', gridService]);
function gridService($http, $rootScope){
return {
LoadNextPage: function (hh) {
alert(hh);
}
};
}

JavaScript angular controller get value from scope from another controller

I have school task.
We have a HTML code like this:
<html ng-app="myTest">
<head><script type="text/javascript" src="../myScript.js"></script>
</head>
<body id="tst" class="textpage" ng-controller="TestController as testcon">
<form class="" id="frm" ng-submit="doStuff()">
<div class="form-group">
{{testinfo}}
</div>
<div class="form-group">
<button type="submit" id="sbtn" name="sbtn">testSubmit</button>
</div>
</form>
</body>
</html>
Content of javascript with name myScript.js is this:
var tester = angular.module('myTest', ['ui.mask']);
tester.controller('TestController', ['$scope', '$http', '$location', '$window', function ($scope, $http, $location, $window) {
$scope.doStuff = function () {
{
$scope.testinfo = 'unknown value';
};
};
}
]);
I have option to add new javascript.
But I am not possible to get value from $scope.testninfo.
I cannot edit existing JavaScript and cannot edit HTML file. I can just add new javascript.
Is there option how to get value from $scope.testinfo in another javascript?
Thanks.

You can use broadcast
From controller 1 we broadcast an event
$scope.$broadcast('myEvent',anyData);
controller 2 will receive our event
$scope.$on('myEvent', function(event,anyData) {
//code for controller 2
});
here anyData represent your object to be passed

Use ng-model.
<div class="form-group">
<input type="text" ng-model="testinfo">
</div>

I dont think it is possible without appending the existing javascript/html. Because the $scope of the TestController cannot be accessed from another controller (file).
If you COULD append the HTML you could use the $rootscope, in that way the value, which is set by the TestController is accessible from another controller. Or you can add a Global app value. I created a fiddle which show the two options: https://jsfiddle.net/Appiez/wnyb9pxc/2/
var tester = angular.module('myTest', []);
tester.value('globalVar', { value: '' });
tester.controller('TestController', ['$rootScope', '$scope', '$http', '$location', '$window', 'globalVar', function ($rootScope, $scope, $http, $location, $window, globalVar) {
$scope.doStuff = function () {
{
$rootScope.testinfo = 'this is the new value';
globalVar.value = 'a global value';
};
};
}
]);
tester.controller('TestController2', ['$rootScope', '$scope', 'globalVar', function ($rootScope, $scope, globalVar) {
$scope.doStuff2 = function () {
{
alert($rootScope.testinfo);
alert(globalVar.value);
};
};
}
]);

This is what services are for in angular. They ferry data across controllers. You can use NG's $broadcast to publish events that contain data, but Providers, Services, and Factories are built to solve this.
angular.module('krs', [])
.controller('OneCtrl', function($scope, data){
$scope.theData = data.getData();
})
.controller('TwoCtrl', function($scope, data){
$scope.theData = data.getData();
})
.service('data', function(){
return {
getData: function(){
return ["Foo", "Bar"];
}
}
});
Here's a fiddle to help get you into the swing of things. Good luck in school!

$injector error when using angular-bootstrap ($modalInstanceProvider <- $modalInstance)

I've been playing around with this bug but I can't seem to figure it out. The problem started when I pushed the angular-bootstrap models I had added to the prod server. The original error was this:
"AngularJS Error: Unknown provider: aProvider <- a"
I'm pretty sure I was getting that error because my files weren't minifying correctly. So I went through my controllers and found that I wasn't $injecting $modal instance into my controllers and that's when I ran into this problem.
Whenever I inject $modalInstance into my controller in the minified format I get this error. I am not using the format angular-bootstrap suggests because I have a lot going on and many controllers on the site I'm building so I combined everything into one controller instead of several functions.
My Controller:
.controller('CreateGroupCtrl', ['$scope', '$http', '$window', '$cookies', '$modal', '$log', 'FeedService', '$modalInstance',
function CreateGroupCtrl($scope, $http, $window, $cookies, $modal, $log, $modalInstance, FeedService) {
$scope.createGroupCall = function createGroupCall(teacher, name) {
if(teacher != null && name != null) {
FeedService.createGroupCall($cookies.token, $window.sessionStorage.user, teacher, name).success(function(data) {
console.log('GroupCreated');
}).error (function(status,data,token) {
console.log(status);
console.log(data);
});
} else {
alert("Error!");
}
}
/***********ANGULAR-UI MODAL CODE**********/
$scope.open = function (size) {
var modalInstance = $modal.open({
templateUrl: 'CreateGroupContent.html',
controller: CreateGroupCtrl,
size: size
});
modalInstance.result.then(function (selectedItem) {
$scope.selected = selectedItem;
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
$scope.ok = function () {
$modalInstance.close();
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
}]);
My Template:
<button ng-controller="CreateGroupCtrl" ng-click="open()" type="button" id="creategroup" class="btn ns-btn">
<img class="ns-add" src="images/createGroup.png">
<p class="create">Create Group</p>
</button>
<div>
<script type="text/ng-template" id="CreateGroupContent.html">

<button class="ns-modal-close" ng-click="cancel()"><img src="images/xCancel.png"></button>
</div>
<div class="modal-body">

At first, you need to inject all in its order.
Also, you should inject $modal into the controller in which you would like to create your modal view. And the $modalInstance can be injected ONLY into the controller which is used for this $modal window. In your case you use the same controller, so you couldn't inject $modalInstance
Demo: http://plnkr.co/edit/khzNQ0?p=preview
Also, in your case (when you use only 1 controller) - you can pass as object field scope which will be used as parent of $scope for your modal view. By default it is $rootScope, but you can type:
$scope.open = function (size) {
var modalInstance = $modal.open({
templateUrl: 'CreateGroupContent.html',
controller: CreateGroupCtrl,
size: size,
scope: $scope
});
So now your functions ok() and cancel() will be available in your modal view and modal scope.

Looks like your FeedService and $modalInstance are mixed up. They need to be in the same order.
