I am trying to use a simple input that can be retrieved by a cookie automatically.
My angular controller is :
<script>
var app = angular.module('mantis', ['ngCookies']);
app.controller('main', function($scope, $cookies) {
$scope.nom = '';
$scope.WriteNom = function () {
$cookies.put('Nom', $scope.nom);
};
$scope.ReadNom = function () {
$scope.nom = $cookies.get('Nom');
return $scope.nom;
};
});
</script>
In my page, I made a div where I can change the variable "nom" flawlessly.
The value should be loaded with ng-init (from cookie)
It changes with ng-model
And it should be saved with ng-click
<div class="container" ng-app="mantis" ng-controller="main">
<!-- Assigné à -->
<div class="col-lg-12">
<div class="input-group" ng-init="nom=ReadNom()">
<span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
<input id="nom" type="text" class="form-control" name="nom" placeholder="Assigné à (id)" ng-model="nom">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button" ng-click="WriteNom()">Sauvegarder</button>
</span>
</div>
</div>
(...)
And then, somewhere else, i can use "nom" where I need it by using {{nom}}
It's almost working :
The value is properly changed when I type in the input box and I can use it
The cookie is not changed when I click on the button nor it's loaded when I load the page
Remove the return part,
HTML:
<div class="input-group" ng-init="ReadNom()">
Controller:
$scope.ReadNom = function () {
$scope.nom = $cookies.get('Nom');
};

I am using angularjs and spring mvc for my application. At first I am displaying all the placements with one button Placed Candidates. I am doing ng-repeat for displaying all the placements.
Here is my html.
<div class="row" data-ng-repeat="placement in placements">
<div class="col-xs-12 col-sm-12 col-md-12">
<h5>{{placement.companyName}}</h5>
</div>
<div class="col-xs-12 col-sm-6 col-md-3">
<h6>{{placement.placementDate | date:'dd MMM yyyy'}}</h6>
Company Target (appox):10 Achieved:
</div>
<a href="javascript:void(0);" data-ng-
click="placedcandidatespopup(placement.placementId);">//here i can
get particular placementId but how to pass this id to
savePlacementStudents() method in controller.js???//
PlacedCandidates
</a>
</div>
I am calling one modal popup function. Here is controller.js
$scope.placedcandidatespopup = function()
{
AdminUsersService.getAllUsers().then(function(response)
{
$scope.allusers=response.data;
console.log($scope.allusers);
})
$(".placedcandidates").modal("show");
}
I am calling modal by name "placedcandidates".
Here is the modal
<div class="modal right fade placedcandidates" id="myModal1"
tabindex="-1" role="dialog" aria-labelledby="myModalLabel2">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-body">
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-6" data-ng-
repeat="student in allusers">
<input id="{{student.studentId}}" type="checkbox" value="
{{student.studentId}}" data-ng-
checked="selection.indexOf(student.studentId) >-1"
data-ng-click="toggleSelection(student.studentId)"/>
<label for="{{student.studentId}}"></label>
{{student.firstName}}
</div>
</div>
</div>
<div class="modal-footer" style="position: fixed;">
<input type="button" value="Submit" class="btn" data-ng-
click="savePlacementStudents()">
</div>
</div>
</div>
</div>
After clicking on button popup modal will display with all Students with checkboxes placed beside them.Now I am able to save studentId into database.But I am not able to pass placementId for saving.
Here is my savePlacementStudents method in controller.js.
$scope.selectedStudents = {};
$scope.savePlacementStudents = function(selectedStudents)
{
selectedStudents.selectedList = $scope.selection;
AdminPlacementService.savePlacementStudents(selectedStudents).then
(function(response)
{
if(response.data=="success"){
$window.scrollTo(0,0);
$scope.selectedStudents = {};
$scope.getplacementdetails($scope.currentPageIndex);
$scope.successmessage="Student Selection Saved!;
$timeout(function() {
$scope.successmessage="";
$scope.closeplacedcandidatespopup();
}, 1500);
}
});
}
Can anyone tell how can I pass respective placementId to this saveStudents method() so that I can set that placementId for those students selected.
Here is the solution.
The placementId passed to function placedcandidatespopup can be saved as follows in function placedcandidatespopup
$scope.selectedPlacementId = placementId;
Now the same $scope will have access in Popup also as it is using same controller.js. And now you can use this $scope.selectedPlacementId anywhere in controller.js
So you don't need to pass placementId...!!
Hope that would help you..!!
$scope.placedcandidatespopup = function(id)
{
AdminUsersService.getAllUsers().then(function(response)
{
$scope.allusers=response.data;
console.log($scope.allusers);
})
$scope.inserted = {
placementId:id,
};
var modalInstance = $uibModal.open({
templateUrl: 'views/test/myModal1.html',
controller: 'TestCntrl',
size: "Modelwidth",
resolve: {
items: function () {
return $scope.inserted;
}
}
});
}
In model you have to access using items.placementId and when you savePlacementStudents() method send placementId as well with student info.
You have to excuse me, I do not use Angular that often. I need to implement a solution in which I can upload files from dynamically generated input fields.
The catch is that I cannot use any directives (this is due to the framework I am using in which AngularJS is implemented).
My current code for creating fields:
$scope.addNewFile = function() {
var newFileNo = $scope.files.length + 1;
$scope.files.push({'id': 'file' + newFileNo});
};
$scope.removeFile = function() {
var lastFile = $scope.files.length - 1;
$scope.files.splice(lastFile);
};
And here is the code for uploading files (not correct, because of static id and name values:
$scope.uploadFile = function() {
var file = document.getElementById('file').files[0],
r = new FileReader;
r.onloadend = function (e) {
var data = e.target.result;
console.log('data');
console.log(data);
// http.post
};
r.readAsArrayBuffer(file);
};
And here is my HTML:
<div data-ng-repeat="file in files">
<div class="row top-buffer">
<div class="col-lg-10">
<input type="file"
ng-model="file.name"
name="file"
class="form-control"
id="file">
</div>
<div class="col-lg-2 text-right">
<div class="btn btn-primary" ng-click="uploadFile()">Upload</div>
</div>
</div>
</div>
<div class="row top-buffer">
<div class="col-lg-11"></div>
<div class="col-lg-1 text-right">
<div class="glyphicon glyphicon-plus" aria-hidden="true" ng-click="addNewFile()"></div>
<div class="glyphicon glyphicon-minus" aria-hidden="true" ng-click="removeFile()"></div>
</div>
</div>
I can't really understand how I can get the values of dynamically generated file fields... any help appreciated!
There is no ng-model for <input type=file, but you can achieve what you want setting the id dynamically with ng-attr:
<div ng-repeat="file in files">
{{file.id}}:
<input type="file"
ng-attr-name="{{file.id}}"
ng-attr-id="{{file.id}}">
</div>
On uploadFile() you can post them:
$scope.uploadFile = function() {
$scope.files.forEach(function(file) {
// $http.post: document.getElementById(file.id).files[0])
});
};

I hope it helps.
Writing an uploader properly is a very difficult task. A major problem with an upload component/directive is getting it to work in Internet Explorer; because it can only be used once in IE. Another problem is that IE will not let you programmatically "press" the button, it must be a real mouse click.
There are upload libraries out there for AngularJs, just google. However if you are intent on doing it yourself then you can use my git repo as an example of how it should be done. Just use the jwtUploader and jwtUploaderButton directives.

I have a problem to show INPUT field when do some action.
I have BUTTON (Click here) as soon as user made a click event on button i wanted to show input field
I have done this by using jQuery.
Can any one help me in Angular.js
<script>
var app = angular.module('myApp', []);

<div class="btn btn-primary" ng-click="openTextBox();">Click Me To open text box</div>
<div ng-show="openTextBox == true">
<input type="text"/>
</div>
SCRIPT :
$scope.openTextBox = function () {
$scope.openTextBox = true;
}
please don't take scope variables and function names same
example here
$scope.openTextBox = function () {
$scope.openTextBox = true;
}
//this is not correct as per angular documentation because scope.openTextBox name already assigned to scope function,again its assigning scope variable "$scope.openTextBox = true" here u will get errors when ever u clicked div second time" TypeError: boolean is not a function" it will throw this error.so please dont use which is already assigned scope function dont assign scope variable

I have a simple text box and a button and whenever user click on button the alert shows the text of textbox but I want to do it this way(I know there are a lot better ways but first I want to understand why this way does not work):
var app = angular.module('app', []);
app.factory('Service', function() {
var service = {
add: add
};
return service;
function add($scope) {
alert($scope.user.username);
}
});
app.controller('table', function(Service,$scope) {
//get the return data from getData funtion in factory
this.add = Service.add($scope);
});
As you can see I send the scope to factory and I define the user.username as follow:
<button class="btn btn-primary" ng-click="t.add(user.userName)">
But when I run this nothing happens can anyone tell me what is wrong with this code?
<body ng-app="app">
<form>
<div class="row commonRow" ng-controller="table as t">
<div class="col-xs-1 text-right">item:</div>
<div class="col-lg-6 text-right">
<input id="txt" type="text" style="width: 100%;"
ng-model="user.userName">
</div>
<div class="col-xs-2">
<button class="btn btn-primary" ng-click="t.add(user.userName)">
click me</button>
</div>
</div>
</form>
also the plnk link is as follow:
plnkr
The problem is in this line
this.add = Service.add($scope);
Here you are assigning the returned (which is undefined) value of the Service.add($scope) invocation to the this.add.
The right approach will be either
this.add = function(data) { Service.add($scope); }
or
this.add = Service.add;
// in the service factory.
function add(usrNm) {
alert(usrNm);
}
The first thing is you can't use $scope in a service.and in controller your not assaining this(object) to $scope.so $scope doesn't contain any value.
I suppose you to write like this
$scope.user = this;
What I'am trying to do is convert every user input into a label using angular. I believe that I'am doing the right thing, but is not working. I will appreciate if somebody take a look at this code. Thank you
here is a plunker
<div class="row" ng-controller="tagForm">
<div ng-click="addEntry()">
<div class="col-xs-12 col-sm-12 col-md-10 ">
<input type="text" placeholder="What are your area of expertise" ng-model="newEntry.name" class="form-control border" />
</div>
<div class="col-xs-12 col-md-2 center form-button">
<input type="button" value="Add" class="btn btn-orange btn-add" />
</div>
<div class="col-md-8 col-sm-offset-2" id="up">
<br />
<span class="label label-primary" ng-repeat="entry in entries">{{entry.name}}</span>
</div>
</div>
</div>
app.controller('tagForm', ['$scope', function($scope) {
return $scope.addEntry = function() {
$scope.entries.push($scope.newEntry);
return $scope.newEntry = {};
};
}]);
You have a few things wrong in your Plunk, but here's some stuff to start with:
You need to wire up a click event on your Add button. Right now, its not doing anything when you click it
Bind to an ng-model on the scope just using 'newEntry'. All you're typing is a name so thats all you need to save on the scope.
Loop over entries, printing out just 'entry' instead of 'entry.name'
And your controller should look like this (no need for the returns)
app.controller('tagForm', ['$scope', function($scope) {
$scope.entries = [];
$scope.addEntry = function() {
$scope.entries.push($scope.newEntry);
};
}]);
