delete seleted image while uploading multiple image in angularjs

In multiple image upload how to delete particular image if i click that image in angularjs.i have uploaded multiple image and i have textbox with every uploaded image.if i click image delete icon it removes the image with that textbox.my view code looks below
<input type="file" multiple file-upload /> {{files.length}}
<div ng-repeat="step in files">
<img ng-src="{{step.src}}" />
<input type="text" ng-model="comment[$index]"><br>
<input type="button" onclick="removeImage($index)" value="delete">
</div>
In my angular controller code looks like below
app.directive('fileUpload', function() {
return {
scope: true, //create a new scope
link: function(scope, el, attrs) {
el.bind('change', function(event) {
var files = event.target.files;
//iterate files since 'multiple' may be specified on the element
for (var i = 0; i < files.length; i++) {
//emit event upward
scope.$emit("fileSelected", {
file: files[i]
});
}
});
}
};
});
$scope.files = [];
$scope.$on("fileSelected", function(event, args) {
var item = args;
$scope.files.push(item);
var reader = new FileReader();
reader.addEventListener("load", function() {
$scope.$apply(function() {
item.src = reader.result;
});
}, false);
if (item.file) {
reader.readAsDataURL(item.file);
}
});

Instead of onclick use ng-click and use javascript splice function to remove an item from an array
<input type="button" ng-click="removeImage($index)" value="delete">
$scope.removeImage = function(index){
$scope.files.splice(index,1)
}

View not updating when splicing user from list in AngularJS

I have this problem in my app, when I use slice to remove the user from the list. However, it does not remove from the list. I am getting the user with a API url call. But for some reason, it does not remove the user from the list. Please, have a look at my code. If, you guys want the full code, I have put it in my github. I hope we both can solve this. Thank you in advance.
Here is my code:
<div ng-controller="MyCtrl">
<div ng-repeat="person in userInfo.lawyers | filter : {id: lawyerId}">
<a class="back" href="#/lawyer">Back</a>
<button type="button" class="edit" ng-show="inactive" ng-click="inactive = !inactive">
Edit
</button>
<button type="submit" class="submit" ng-show="!inactive" ng-click="inactive = !inactive">Save</button>
<a class="delete" ng-click="confirmClick(); confirmedAction(person);" confirm-click>Confirm</a>
<div class="people-view">
<h2 class="name">{{person.firstName}}</h2>
<h2 class="name">{{person.lastName}}</h2>
<span class="title">{{person.email}}</span>
<span class="date">{{person.website}} </span>
</div>
<div class="list-view">
<form>
<fieldset ng-disabled="inactive">

But the element is getting deleted from list right?
If yes then, Try this :
$scope.confirmedAction = function (lawyer) {
$scope.$apply(function () {
var index = $scope.userInfo.lawyers.indexOf(lawyer);
console.log($scope.userInfo.lawyers);
$scope.userInfo.lawyers.splice(index, 1);
console.log($scope.userInfo.lawyers);
$window.location.href = '#/lawyer';
});
});
Or
$scope.confirmedAction = function (lawyer) {
$timeout(function () {
var index = $scope.userInfo.lawyers.indexOf(lawyer);
console.log($scope.userInfo.lawyers);
$scope.userInfo.lawyers.splice(index, 1);
console.log($scope.userInfo.lawyers);
$state.go($state.current, {}, {reload: true});
// $window.location.href = '#/lawyer';
},1100);
});

The problem is that you don't get the index from IndexOf when you using it on an array of objects like you do. Read more about the IndexOf here.
Instead, use map and then use IndexOf on that
Try it like this:
$scope.confirmedAction = function (lawyer) {
var index = $scope.userInfo.lawyers.map(function(e) { return e.id; }).indexOf(lawyer.id);
$scope.userInfo.lawyers.splice(index, 1);
console.log($scope.userInfo.lawyers);
$window.location.href = '#/lawyer';
};
And also, the controller changes will by default be detected by the digest loop of angular so no need to use $scope.$apply.
Also, simplifyed your plunker with the basic get array list and remove function. Use that to build your way forvered

AngularJS - convert file object to image object

Is it possible to convert file object to image object?
I need width and height from file (which is an image), here is my code:
view:
<button id="image_file" class="md-button md-raised md-primary"
type="file" ngf-select="uploadFile($file)">
SELECT FILE
</button>
<md-input-container>
<div class="raised">
<input id="image_file_name" type="text" ng-model="vm.file.name"></input>
</div>
</md-input-container>
controller:
app.controller('imageController', function($scope, fileService) {
$scope.vm = {};
$('.intro').show(1000);
$scope.uploadFile = function(file) {
$scope.vm.file = "";
$scope.vm.file = file; //<---- for example here, how it should be done?
fileService.uploadFile($scope);
}
service:
angular.module('app')
.service('fileService', function ($http, validationService) {
this.uploadFile = function ($scope){
if (validationService.isFileValidate($scope)) {
$scope.vm.acceptableFormat = true;
} else {
$scope.vm.acceptableFormat = false;
}
};
});

The library already seems to give most of what you require. To read width and height properties of the file/image .
//Add accept option to filter only images
<button id="image_file" class="md-button md-raised md-primary"
type="file" accept="image/*" ngf-select="uploadFile($file)">
SELECT FILE
</button>
Controller
$scope.uploadFile = function(file) {
$scope.vm.file = "";
$scope.vm.file = file;
// show all file properties
console.log(file); // Show available properties
console.log(file.$ngfWidth +','+ file.$ngfHeight) // Your width and height
fileService.uploadFile($scope);
}

Send values/parameters to uibModal angular

I have a page employee.html with a list of dependents and for each row (li) an inner button with the directive ng-click="editDependent({{dependent.id}})". That button tries to call a modal box.
The employee.html is loaded in a ui_view div from an index.html
I saw that each button in view source with chrome are correctly bound ng-click="editDepedent(1)" and so on.
But at the same time I have an error
angular.min.js:118 Error: [$parse:syntax] http://errors.angularjs.org/1.5.8/$parse/syntax?p0=%7B&p1=invalid%20key&p2=11&p3=editDependent(%7B%7Bdependent.id%7D%7D)&p4=%7Bdependent.id%7D%7D)
I'm trying to pass my dependent id to my modal and the previous scope also that contains the info about the employee. So how can I achieve this parameter passing?
This is my main controller
app.controller('EmployeeController', function ($scope, $stateParams, $uibModal, EmployeeService) {
if($stateParams.id){
EmployeeService.getEmployee($stateParams.id).then(function(employee){
$scope.employee = employee;
EmployeeService.setCurrentEmployee(employee);
});
}
$scope.editDependent = function(id){
if(id){
$scope.dependentid = id;
}
var uibModalInstance = $uibModal.open({
templateUrl : 'modal_dependent.html',
controller : 'DependentController',
scope: $scope
});
return uibModalInstance;
}
});
This is my dependent controller to catch the value
app.controller('DependentController', function($scope, $uibModal, $uibModalInstance, $stateParams, EmployeeService){
//Following line does not work because it gets the ID of employee which is passed by querystring
//var dependentID = $stateParams.id;
if($scope.dependentid){
var currentEmployee = EmployeeService.getCurrentEmployee();
//find the current dependent
for(var i = 0; i < currentEmployee.dependents.length; i++){
//*****************************************************
//Hardcoding 1 to test the dependent number 1 but it should be the dependent id parameter
if(currentEmployee.dependents[i].id == 1){
$scope.dependent = currentEmployee.dependents[i];
break;
}
}
}else{
$scope.dependent = { id : 0 };
}
$scope.editableDependent = angular.copy($scope.dependent);
//Submit button in modal
$scope.submitDependent = function(){
DependentService.saveDependent($scope.editableDependent);
$scope.dependent = angular.copy($scope.editableDependent);
$uibModalInstance.close();
}
});
UPDATE
employee.html
<form name="employee_form">
<div>
<h1> {{employee.name}} </h1>
<h3>Dependents</h3>
<button class="btn bgcolor-rb-main" x-ng-click="editDependent(0)">
Add new
</button>
<ul class="list-inline">
<li x-ng-repeat="dependent in employee.dependents">
<button x-ng-click="editDependent({{dependent.id}})">
Edit
</button><br>
<div>{{dependent.name}}</div>
</li>
</ul>
</div>
</form>
This is my modal_dependent.html
<div class="modal-header">
<h4>Dependent</h4>
</div>
<div class="modal-body">
<div class="form-group">
<input type="text" id="txtName" x-ng-model="editableDependent.name" />
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" x-ng-click="discardChanges()">Discard</button>
<button type="submit" class="btn btn-primary" x-ng-click="submitDependent()">Save</button>
</div>
UPDATE
I changed my controller to initialize before $scope.dependent
app.controller('DependentController', function($scope, $uibModal, $uibModalInstance, $stateParams, EmployeeService){
//Following line does not work because it gets the ID of employee which is passed by querystring
//var dependentID = $stateParams.id;
$scope.dependent = { id : 0 };
if($scope.dependentid){
var currentEmployee = EmployeeService.getCurrentEmployee();
//find the current dependent
for(var i = 0; i < currentEmployee.dependents.length; i++){
//*****************************************************
//Hardcoding 1 to test the dependent number 1 but it should be the dependent id parameter
if(currentEmployee.dependents[i].id == 1){
$scope.dependent = currentEmployee.dependents[i];
break;
}
}
}
$scope.editableDependent = angular.copy($scope.dependent);
//Submit button in modal
$scope.submitDependent = function(){
DependentService.saveDependent($scope.editableDependent);
$scope.dependent = angular.copy($scope.editableDependent);
$uibModalInstance.close();
}
});
SOLVED
My button changed from this
<button x-ng-click="editDependent({{dependent.id}})">Edit</button>
To this
<button x-ng-click="editDependent(dependent.id)">Edit</button>

i think there is parsing error you have to define
$scope.dependentid = {};
before using it,
or otherwise you can use it as a model (if you are submitting a form on frontend like this)
<input type="hidden" ng-model="dependentid" />
it will be better to understand for me if you edit the code and add some frontend html

Tab Through Hidden Inputs in Angular

I'm looking for a way in angular to tab through hidden inputs. So I have multiple input forms but when not on focus I want them to just display the text. I'm looking for the ability to once I've selected an input to tab through the other inputs even though they are currently hidden.
Any suggestions?

Use Angular directives to make your inputs into inline editors. When the page loads you'll be in display mode (i.e. the display div will be shown and the editor div will be hidden), then on clicking, the mode switches to Edit mode and the visibility is reversed.
Here's a quick snippet of what a DatePicker control would look like when wrapped in such a directive. Using Angular 1 and Bootstrap 3 (follows John Papa's Angular Style Guide):
HTML Template (inlineDatePicker.html):
<div class="inline-edit">
<div ng-if="!vm.inEditMode" data-ng-click="vm.enableEditMode()">
<input type="hidden" data-ng-model="vm.dateModel" data-ng-required="vm.dateRequired" /><span>{{vm.dateModel}}</span> <span class="glyphicon glyphicon-calendar"></span>
</div>
<div ng-if="vm.inEditMode">
<div class="well well-sm" style="position: absolute; z-index: 10">
<datepicker data-ng-model="vm.dateModel" data-show-weeks="false"></datepicker>
<button type="button" class="btn btn-sm btn-info" ng-click="vm.today()">Today</button>
<button type="button" class="btn btn-sm btn-danger" ng-click="vm.cancel()">Cancel</button>
</div>
</div>
</div>
And the underlying directive (inlineDatePicker.directive.js):
(function () {
'use strict';
angular.module('myApp.inlineEdit')
.directive('inlineDatePicker', inlineDatePicker);
function inlineDatePicker() {
'use strict';
inlineDatePickerController.$inject = ['$scope', '$timeout'];
return {
restrict: 'A',
replace: true,
transclude: false,
templateUrl: '/App/inlineEdit/date/inlineDatePicker.html',
scope: {
dateModel: '=',
dateRequired: '#',
dateChanged: '&'
},
controller: inlineDatePickerController,
controllerAs: 'vm',
};
function inlineDatePickerController($scope, $timeout) {
/* jshint validthis:true */
var vm = this;
vm.inEditMode = false;
vm.dateModel = $scope.dateModel;
vm.dateRequired = $scope.$eval($scope.dateRequired);
vm.enableEditMode = enableEditMode;
vm.cancel = cancel;
vm.today = today;
function enableEditMode() {
vm.inEditMode = true;
}
function cancel() {
vm.inEditMode = false;
}
function today() {
vm.dateModel = new Date();
}
$scope.$watch('vm.dateModel', function (curr, orig) {
$scope.dateModel = vm.dateModel;
if (curr != orig && vm.inEditMode) {
$timeout($scope.dateChanged, 0);
}
vm.inEditMode = false;
});
$scope.$watch('dateModel', function () {
vm.dateModel = $scope.dateModel;
});
}
}
})();
