Angularjs file upload - angularjs

html
<form method='POST' enctype='multipart/form-data' name="formName">
<div class="row">
<div class="col-md-6">
<input type="file" style="text-align: left" ng-model="value" class="btn"/>
</div>
<div class="col-md-2">
<input type="submit" value="upload" class="btn btn-info" ng-click="submitFile()"/>
</div>
</div>
</form>
AngularJs
$scope.submitFile = function(){
document.formName.action = 'http://xxx.xxx.xxx.xxx:8000/ww/up?s=' + $rootScope.reply.Sid; //$rootScope.reply.Sid is secession id
document.formName.submit();
};
I am trying to do a fileupload with AngularJs. Will this logic work?. My selected path is also coming as given below.
C:\fakepath\license.txt
Is this an error?
Note:
Our UI team was able to the fileupload with the below code. I was trying to attain the same thing in AngularJs
<body>
<form method='POST' enctype='multipart/form-data' action="http://xxx.xxx.xx.xxx:xxxx/yyy/yyyyyyyyy?s=3e3646ea-48cc-4342-a388-e0c0d7bbf4e4"/'>
File to upload: <input type=file id='up_file' name=upfile><br>
</body>

You did it right .. you only have to change few things to make it work
Change
<form method='POST' enctype='multipart/form-data' name="formName">
To
<form action="{{action}}" method='POST' enctype='multipart/form-data' name="formName">
In controller inject $timeout along with $scope
app.controller('Test', function($scope, $rootScope, $timeout){
$scope.submitFile = function(){
$scope.action = 'http://xxx.xxx.xxx.xxx:8000/ww/up?s=' + $rootScope.reply.Sid;
$timeout(function(){
document.formName.submit();
}, 100);
}
});
Action assigning $scope.action with new data .. angularjs needs to update the dom .. that is the reason we are using $timeout and submitting the form

I am providing an example of Upload File. To develop this app, we have used HTML, CSS and AngularJS. Following example shows about how to upload the file using AngularJS.
<html>
<head>
<script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
</head>
<body ng-app = "myApp">
<div ng-controller = "myCtrl">
<input type = "file" file-model = "myFile"/>
<button ng-click = "uploadFile()">upload me</button>
</div>
<script>
var myApp = angular.module('myApp', []);
myApp.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
myApp.service('fileUpload', ['$http', function ($http) {
this.uploadFileToUrl = function(file, uploadUrl){
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}
}]);
myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "/fileUpload";
fileUpload.uploadFileToUrl(file, uploadUrl);
};
}]);
</script>
</body>
</html>
This is a working example with no other dependencies than AngularJS

How to pass data-plugin="timepicker" value to controller in angularJS

I have code to pass date and time to controller.
Here is HTML code,
<div class="page-content" ng-app="app">
<div ng-controller="postAppoinmentCtr as ctrl" class="panel-body">
<form ng-submit="submitForm()" id="form1">
<input name="time" ng-model="time" type="text" class="form-control" ng-model="time" data-plugin="timepicker" autocomplete="off"/>
<input name="date" ng-model="date" type="text" class="form-control" data-plugin="datepicker"/>
<input..ng-model="type"...></input>
<input..ng-model="Description"...></input>
<button ...>
</form>
</div>
</div>
Here is angular js part
var app = angular.module('app', []);
app.controller('postAppoinmentCtr', function($scope, $http, $location) {
$scope.submitForm = function(){
var url = $location.absUrl() + "/addAppoinment";
alert(url);
var config = {
headers : {
'Content-Type': 'application/json;charset=utf-8;'
}
}
var data = {
type: $scope.type,
date: $scope.date,
time: $scope.time,
description: $scope.description
};
$http.post(url, data, config).then(function (response) {
$scope.postResultMessage = "Sucessful!";
}, function (response) {
$scope.postResultMessage = "Fail!";
});
$scope.type = "";
$scope.date = "";
$scope.time ="";
$scope.description ="";
}
});
When click the button type and description pass to controller. But date and time not. I can do this using
<input id="date-birth" class="form-control" type="date" ng-model="date">
this line. But I need to use data-plugin="datepicker" .
I'm new one for the angularjs and I try to many ways for solve this problem.
Please give me some answer this. Thanks in advance.

How to trigger element click on angular js?

I have an input file and it is hidden. I want to trigger the input file once the button is clicked but my code is not working. What changes does it need to make it work?
HTML:
<input type="file" ng-model="data.file" id="upload" style="display:none;">
<button type="button" ng-click="browseFile()">Choose a file</button>
JavaScript:
$scope.browseFile = function () {
angular.element(document.querySelector('#upload')).triggerHandler('click');
}
In html use something like below
<img id="preview_image" src="" accept="image/*" class="upload_img" alt="">
<input id="image_upload" ng-model="file" type="file" class="upload_image_file" />
And in controller use $watch
$scope.$watch("file", function() {
readURL(angular.element("#image_upload")[0]);
});
function readURL(input) {
if (input && input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
angular.element("#preview_image").attr("src", e.target.result);
vm.base64File = e.target.result;
};
reader.readAsDataURL(input.files[0]);
}
}
For more info, read here and here
Update
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.file = '';
$scope.$watch("file", function() {
console.log($scope.file)
});
});
app.directive('fileModel', ['$parse', function($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function() {
scope.$apply(function() {
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<label class="upload_image_label" for="image_upload">
choose file
<input id="image_upload" file-model="file" type="file" style="display:none" />
</label>
<hr> <br> File: {{file}}
</div>
</body>
</html>
As adardesign said
This is due to a security restriction.
I found out that the security restriction is only when the
<input type="file"/>
is set to display:none; or is visibility:hidden.
So i tried positioning it outside the viewport by setting
position:absolute and top:-100px; and voilĂ  it works.

Using AngularJS, how can I pass a clicked object property to a function?

Using AngularJS, I am creating a wizard. In order to navigate properly, the clicked wizardresult.Title needs to be passed into the function showpagetwo().
Here is the HTML:
<div ng-app="wizardApp">
<div ng-controller="MainCtrl">
<div ng-repeat="wizardresult in wizardresults">
<div id="initial" ng-if="wizardresult.RootItem =='Yes'">
<button type="button" class="btn btn-primary" ng-click="showpagetwo()">{{wizardresult.Title}}
...
</button>
</div>
<div id="pagetwo" style="display:none">
...
</div>
</div>
</div>
</div>
My JS:
function showpagetwo(){
console.log("Hello");
$("#pagetwo").fadeIn();
$( "#initial" ).hide()
}
var app = angular.module('wizardApp', []);
app.controller('MainCtrl', function($scope, $http, $q){
var supportList;
$(document).ready(function() {
$scope.getSupportList();
});
$scope.prepContext = function(url,listname,query){
var path = url + "/_api/web/lists/getbytitle('" + listname + "')/items" + query;
return path;
}
$scope.getSupportList = function() {
supportList = $http({
method: 'GET',
url: this.prepContext(siteOrigin+"/divisions/testing","SupportList","?$orderBy=Title"),
headers: {
"Accept": "application/json; odata=verbose"
}
}).then(function(data) {
//$("#articleSection").fadeIn(2000);
console.log(data.data.d.results);
$scope.wizardresults = data.data.d.results;
});
};
});
I have tried ng-click="showpagetwo(wizardresult.Title)" and just ng-click="showpagetwo()"but the function is not firing at all either way.
What is my issue here?
You just need to put your callback function in the $scope and pass the argument you want to receive.
Something like this:
HTML:
<div class="test" ng-controller="Ctrl">
<button ng-click="myFn(wizardresult.Title);">click me</button>
<div>
JS:
var app = angular.module('app', []);
function Ctrl($scope) {
$scope.wizardresult = {Title: 'myname'};
$scope.myFn = function(param){
alert("Param: " + param);
};
}
Check this jsfiddle: http://jsfiddle.net/m1q4q4cm/
Add the function showpagetwo() inside controller.
var app = angular.module('wizardApp', []);
app.controller('MainCtrl', function($scope, $http, $q){
var supportList;
$(document).ready(function() {
$scope.getSupportList();
});
$scope.prepContext = function(url,listname,query){
var path = url + "/_api/web/lists/getbytitle('" + listname + "')/items" + query;
return path;
}
$scope.showpagetwo= function(title){
console.log("Hello "+title);
$("#pagetwo").fadeIn();
$( "#initial" ).hide()
}
$scope.getSupportList = function() {
supportList = $http({
method: 'GET',
url: this.prepContext(siteOrigin+"/divisions/testing","SupportList","?$orderBy=Title"),
headers: {
"Accept": "application/json; odata=verbose"
}
}).then(function(data) {
//$("#articleSection").fadeIn(2000);
console.log(data.data.d.results);
$scope.wizardresults = data.data.d.results;
});
};
});
You cannot call a function outside your app directly with ng-click. The angular way of what you are trying to achieve will be like
Html
<div ng-app="wizardApp">
<div ng-controller="MainCtrl">
<div ng-repeat="wizardresult in wizardresults">
<div id="initial" ng-if="wizardresult.RootItem =='Yes'" ng-show="showThisDiv">
<button type="button" class="btn btn-primary" ng-click="showpagetwo(wizardresult.Title)">{{wizardresult.Title}}
...
</button>
</div>
<div id="pagetwo" ng-hide="showThisDiv">
...
</div>
</div>
</div>
</div>
Controller
app.controller('MainCtrl', function($scope, $http, $q){
$scope.showThisDiv = true
$scope.showpagetwo = function(wizardTitle){
$scope.showThisDiv = true
}
});
For the animation effects, you can use angular-animate library and add class="animate-show animate-hide" to divs for the fade effects.
For some reason if you want to use jquery, then just change the scope function to
$scope.showpagetwo = function(wizardTitle){
$("#pagetwo").fadeIn();
$( "#initial" ).hide()
}
Hope this will help.

Image is not changing even i changed image

In angularjs if i change or remove image it does not make any changes. After refreshing the page it show the changed image.I am using following line to remove image
jQuery
$('#profile_image').val('')
This Sample is basic if you want to know more about AngularJs click on link
var app = angular.module("app", []);
app.controller("ctrl", [
"$scope",
function($scope) {
$scope.imgShow = true;
$scope.imgSrc = "https://www.gravatar.com/avatar/75025ad9a8cfdaa5772545e6e8f41133?s=32&d=identicon&r=PG&f=1";
$scope.display = function() {
$scope.imgShow = true;
$scope.imgSrc = "https://www.gravatar.com/avatar/75025ad9a8cfdaa5772545e6e8f41133?s=32&d=identicon&r=PG&f=1";
}
$scope.change = function() {
$scope.imgSrc = "https://www.gravatar.com/avatar/fccd71b79b3571b459cdfe40e7bf5dd8?s=32&d=identicon&r=PG&f=1";
}
$scope.remove = function() {
$scope.imgShow = false;
}
}
]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<img ng-src="{{imgSrc}}" ng-show="imgShow">
<hr/>
<button ng-click="display()" ng-hide="imgShow">display image</button>
<button ng-click="change()">change image</button>
<button ng-click="remove()">remove image</button>
</div>
If you want to manipulate the DOM in AngularJS you should use directives for this purpose.
You should avoid using jquery inside of your controllers and simply work with your model. Below is fileUpload directive that could help you to work with <input type="file"> in a more angularjs-way:
angular.module('myApp', [])
.controller('TestController', ['$scope', function ($scope) {
var ctrl = this;
ctrl.imageFile = null;
ctrl.clearFile = clearFile;
function clearFile(){
ctrl.imageFile = null;
}
$scope.$ctrl = ctrl;
}])
.directive('fileUpload', [function () {
return {
require: "ngModel",
restrict: 'A',
link: function ($scope, el, attrs, ngModel) {
function onChange (event) {
//update bindings with $applyAsync
$scope.$applyAsync(function(){
ngModel.$setViewValue(event.target.files[0]);
});
}
//change event handler
el.on('change', onChange);
//set up a $watch for the ngModel.$viewValue
$scope.$watch(function () {
return ngModel.$viewValue;
}, function (value) {
//clear input value if model was cleared
if (!value) {
el.val("");
}
});
//remove change event handler on $destroy
$scope.$on('$destroy', function(){
el.off('change', onChange);
});
}
};
}]);
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="//code.angularjs.org/1.3.20/angular.js"></script>
<div ng-app="myApp">
<div ng-controller="TestController">
<input type="file" file-upload ng-model="$ctrl.imageFile" />
<input type="button" ng-click="$ctrl.clearFile()" value="Reset" />
<div ng-if="$ctrl.imageFile">
{{$ctrl.imageFile.name}}<br />
{{$ctrl.imageFile.size}} byte(s)<br/>
{{$ctrl.imageFile.type}}
</div>
</div>
</div>

Why won't my service register?

I tried creating a service in angularjs but I keep getting angular.js:10467 Error: [ng:areq] Argument 'MainController' is not a function, got undefined.
html:
<div ng-controller="MainController">
<form name="searchUser" method="post">
<input ng-model="username" type="search" placeholder="Find"/>
<input type="submit" value="Search" ng-click="search(username)" />
</form>
You are searching for: {{username}}
<hr />
<div ng-repeat="(key,value) in data">
{{ key + " : " + value}}
</div>
</div>
<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="services/Screamer.js"></script>
my app.js:
angular.module('NoteTaker', []); // dependcies in array.
angular.module('NoteTaker', []).controller('MainController', function(screamer, $log, $http, $scope, $interval){
$http({
method : 'GET',
url: 'https://api.github.com/users/' + $scope.username
}).then(function(response){
console.log(response);
$scope.data = response.data;
}, function(response){
console.log(response);
});
my service in service.js
(function() {
'use strict';
angular.module('NoteTaker', []).factory('screamer', function(){
return {
say: "blahbalh"
};
});
}());
angular.module(name, dependencies) creates a new module. If you want to add to an existing one, use angular.module(name):
angular.module('NoteTaker', []); // dependcies in array.
angular.module('NoteTaker')
.controller('MainController', function(screamer, $log, $http, $scope, $interval) {
$http({
method: 'GET',
url: 'https://api.github.com/users/' + $scope.username
}).then(function(response) {
console.log(response);
$scope.data = response.data;

console.log(response);
});
});
// service.js
(function() {
'use strict';
angular.module('NoteTaker').factory('screamer', function() {
return {
say: "blahbalh"
};

I create a new module on line 1, and add the controller & service to it.
tcooc answered your question, but I'll try to make it a little easier to understand:
app.module('myModule', ['dep1', 'dep2']); // passing an array creates a NEW module
Access the newly created module by calling the same method, but without the array of dependencies:
app.module('myModule')
.controller('MyController')
.service('MyService')
.factory('MyFactory');
Or, just attach everything to the first module call:
app.module('myModule', ['dep1', 'dep2'])
.controller('MyController', function(...) {})
.service('MyService', function(...) {})
.factory('MyFactory', function(...) {});
Also, it helps to write dependency injection like this:
MyController.$inject = ['$scope', '$location', '$log'];
function MyController($scope, $location, $log) {
}
MyService.$inject = ['$http'];
function MyService($http) {
}
This makes it clear what is getting injected where. And it makes your code much more readable, since you can now write this:
app.module('myModule', ['dep1', 'dep2'])
.controller('MyController', MyController)
.service('MyService', MyService);
