angularjs get form action and submit to it - javascript

I have a form and I want to catch it submission, check validation of data and than submit form to the action inside the HTML form.
<div ng-controller="contactCtrl">
<form action="someAction" method="post" name="contactForm" class="clearfix frmContact">
<div class="one_half">
<input id="txtName" ng-model="name" value="" class="form-control">
</div>
<button ng_click="save($event)" type="submit">Send Message</button>
</form>
</div>
and my js:
var app = angular.module('bloompyApp', []);
app.controller("contactCtrl", function($scope, $http) {
$scope.email = "";
$scope.name = "";
$scope.message = "";
$scope.left = function() {return 100 - $scope.message.length;};
$scope.clear = function() {$scope.message = "";};
$scope.save = function(ev) {
ev.preventDefault();
console.log(angular.element(document.querySelector('body')));
if ($scope.contactForm.$valid) {
$http.get("/posts/")
.success(function(response) {console.log(response);});
}
};
});

You should:
Use the ng-submit directive on your form
Pass the form element to your save() method
Use the $http service to post
var ctrl = function ($scope, $http, $log) {
$scope.save = function (form) {
//if (!$scope.contactForm.$valid) return;
var url = form.attributes["target"];
$log.debug(url);
$http
.post(url, { email: $scope.email, name: $scope.name })
.success(function (response) {
$log.debug(response);
})
}
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<form ng-submit="save($element.action)">
<button type="submit">Send Message</button>
</form>
</div>

I really advice you to follow this page of the docs from the beginning to the end, you'll change your approach to form using AngularJS :)
https://docs.angularjs.org/guide/forms

Use ng-submit instead on the form element
"Additionally it prevents the default action (which for form means sending the request to the server and reloading the current page), but only if the form does not contain action, data-action, or x-action attributes."
It will also only run the expressions if the native html5 validation is valid

How to add new record to database with AngularJS and Laravel 5 on right way

I found a guide on how to write AngularJS the right way: https://github.com/johnpapa/angular-styleguide#factories
In Laravel, I created my POST route /api/addnew and now I need to pass params from Angular to Laravel.
This is my form:
<form id="1" class="dd animated slideInDown ng-pristine ng-valid">
<textarea class="form-control" placeholder="Vas Komentar" id="rep_text_0"></textarea>
Send
</form>
And my factory:
angular.module('commentsApp')
.factory('commentFactory', dataService);
dataSerive.$inject();
function dataService() {
var someValue = '';
var service = {
save: save,
someValue: someValue
};
return service;
////////////
function save() {
/* */
};
}
Click directive:
angular
.module('commentsApp')
.directive('addComment', addNewComment);
function addNewComment() {
var directive = {
link: link,
restrict: 'A'
};
return directive;
function link(scope, element, attrs) {
/* */
}
}
I'm stuck on how to pass details from the form to Angular and then make a post request on /api/addnew with the params?
Is there any way to use the click directive on a button to send params to the factory?
I don't think is necessary a directive for a click...
instead use ng-click and manage data (model) from the controller.
<div ng-controller="yourController">
<form id="1" class="dd animated slideInDown ng-pristine ng-valid">
<textarea class="form-control" placeholder="Vas Komentar" id="rep_text_0" ng-model="yourCommentModel"></textarea>
Send
</form>
</div>
In your controller you can use $http or your own factory.
yourApp.controller('yourController', function($scope, $http, yourFactory){
$scope.sendText = function(data){
//http code...
//or yourFactory code..
};
});

Can't update $rootScope value after submit action

I'm a beginner with AngularJS. However, I can't update $rootScope value after submit a form, it's being returned as undefined.
The Controller:
app.controller('campaignCtrl', ['$scope', '$rootScope', function($scope, $rootScope) {
$scope.submit = function() {
$rootScope.campaign = this.campaign;
};
}]);
And the form:
<form class="holder" name="campaignForm" ng-submit="submit()" >
<div class="form-group" show-errors>
<label for="inputDate">Date</label>
<p class="help-block"><em>Ex: 12/10/2015</em></p>
<input type="date" class="form-control" name="inputDate" ng-model="campaign.date" id="inputDate" required>
</div>
<button type="submit" class="btn btn-lg btn-default pull-right">Submit</button>
</form>
I used your code and added a $watch on $rootScope.campaign and it worked great.
.controller('someController', function($scope, $rootScope) {
$scope.submit = function() {
$rootScope.campaign = $scope.campaign;
};
$rootScope.$watch('campaign', function(newVal, oldVal) {
if(newVal !== oldVal) {
console.log("New Val = ");
console.log(newVal);
}
});
});
JSFiddle
If you are looking for something that persists across a page refresh, that is not $rootScope. Look at something like this: AngualrJS: sustaining data on html refresh
Check this. Your code seems correct except that you are missing closing tag on the input
`http://jsfiddle.net/ashishmusale/2001cf6r/`
Try
$scope.submit = function() {
$rootScope.campaign = $scope.campaign;
};
EDIT:
Try removing type="submit" from your button. It could be that your handler doesn't get called because the browser handles the form submission automatically (although you could verify that by putting a log in that function).
<button class="btn btn-lg btn-default pull-right">Submit</button>
EDIT 2:
Per our conversation via comments: $rootScope doesn't persist across requests. You'll need to store it somewhere permanent (like local storage or a cookie) or pass it to the server and then back to the client if you want to hold on to that value. I bet if you add a log inside that $scope.submit function, it will have a value there.

Submit form on page load in Angular

I would like to submit a search form on page load if search terms were specified in the route. The problem is that searchForm isn't defined yet when search() runs. I've seen others get this to work by putting ng-controller right on the form element, but I have multiple forms on this page, so the controller has to be a parent of the forms.
How can I ensure the form is defined when I call search()?
myModule.controller('MyController', ['$scope', '$routeParams',
function($scope, $routeParams){
$scope.model = {searchTerms: ""};
$scope.search = function(){
if($scope.searchForm.$valid){
...
}
};
if($routeParams.terms !=""){
$scope.model.searchTerms = $routeParams.terms;
$scope.search();
}
}]);
View:
<div ng-controller="MyController">
<form name="searchForm" ng-submit="search()">
...
</form>
<form name="detailForm" ng-submit="save()">
...
</form>
</div>
This seems to work:
$scope.$on('$routeChangeSuccess', function () {
if($routeParams.terms !=""){
$scope.model.searchTerms = $routeParams.terms;
$scope.search();
}
});
Have you tried just using $watch on searchForm?
if($routeParams.terms != "") {
var unregister = $scope.$watch(function() {
return $scope.searchForm;
}, function() {
// might want to wrap this an if-statement so you can wait until the proper change.
unregister(); //stop watching
$scope.model.searchTerms = $routeParams.terms;
$scope.search();
});
}

Define default values in angularjs form, validation doesnt'work

I'm lost about define default values in my form : http://1ffa3ba638.url-de-test.ws/zombieReport/partials/popup.html
validation doesnt'work too...
/*********************************** SubmitCtrl ***********************************/
app.controller('SubmitCtrl', ['$scope', '$http', '$timeout', function($scope, $http, $timeout) {
/* data pre-define : date & url for test */
$scope.myForm = {};
$scope.myForm.date = new Date();
$scope.myForm.url = "prout";
/* ng-show things */
$scope.successMailZR = false;
$scope.errorMailZR = false;
$scope.send = function() {
if ($scope.myForm.$valid) {
alert('ok');
}
};
}]);
What is the correct way for define default values ?
edit :
for url i do it like this :
<input type="text" class="form-control" name="url" placeholder="{{myForm.url}}" value="{{myForm.url}}" ng-model="myForm.url" readonly="readonly" />
it's not working
There is a conflict between a binding model $scope.myForm and the form name <form name="myForm".
Angular will assign the form's controller into the $scope as its name i.e. $scope.myForm and that override what you have initialized.
Change your form name or the binding variable to have a different name.
In HTML:
<input value="default">
Or using Angular's ng-model:
<div ng-controller="YourCtrl">
<input ng-model="value">
</div>
function YourCtrl($scope) {
$scope.value = 'default';
}

Sending POST with hidden <input> value does't work in AngularJs

In my web app, There are many form on a page. I want to submit it with AngularJS for specific form.
In each of form, it need unique ID with Hidden Value to submit. But value="UNIQUE_ID" seen doesn't work in hidden input box in AngularJS.
My HTML
<div ng-app>
<div ng-controller="SearchCtrl">
<form class="well form-search">
<input type="text" ng-model="keywords" name="qaq_id" value="UNIQUE_ID">
<pre ng-model="result">
{{result}}
</pre>
<form>
</div>
</div>
This is js script
function SearchCtrl($scope, $http) {
$scope.url = 'qa/vote_up'; // The url of our search
// The function that will be executed on button click (ng-click="search()")
$scope.search = function() {
// Create the http post request
// the data holds the keywords
// The request is a JSON request.
$http.post($scope.url, { "data" : $scope.keywords}).
success(function(data, status) {
$scope.status = status;
$scope.data = data;
$scope.result = data; // Show result from server in our <pre></pre> element
})
.
error(function(data, status) {
$scope.data = data || "Request failed";
$scope.status = status;
});
};
}
It may be that the only reason your code is not working is that $scope.keywords is a simple variable (with a text value) instead of an Object, which is required - see http://docs.angularjs.org/api/ng.$http#Usage
As angularJS works with variables within its own scope - its models, a form becomes just a way to interact with those models, wich can be sent via whatever method you want.
You can have a hidden field, yes, but in angularJS it isn't even necessary. You only need that information to be defined in the controller itself - randomly generated for each instance, or received from some other source.. Or you can define it yourself, upon the loading of the controller, for instance.
So (and only for sake of clarity) if you define a formData variable within your formCtrl:
Your HTML:
<div ng-app>
<div ng-controller="SearchCtrl">
<form class="well form-search">
<input type="text" ng-model="formData.title">
<input type="textarea" ng-model="formData.body">
<button ng-click="sendData()">Send!</button>
</form>
<pre ng-model="result">
{{result}}
</pre>
</div>
</div>
And your controller:
function SearchCtrl($scope, $http) {
$scope.url = 'qa/vote_up'; // The url of our search
// there is a formData object for each instance of
// SearchCtrl, with an id defined randomly
// Code from http://stackoverflow.com/a/1349426/1794563
function makeid()
{
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for( var i=0; i < 5; i++ )
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
$scope.formData = {
title: "",
text: ""
};
$scope.formData.id = makeid();
// The function that will be executed on button click (ng-click="sendData()")
$scope.sendData = function() {
// Create the http post request
// the data holds the keywords
// The request is a JSON request.
$http.post($scope.url, { "data" : $scope.formData}).
success(function(data, status) {
$scope.status = status;
$scope.data = data;
$scope.result = data; // Show result from server in our <pre></pre> element
})
.
error(function(data, status) {
$scope.data = data || "Request failed";
$scope.status = status;
});
};
}
Also: If you wanted to set the unique id on the html itself, you could add an input type="hidden" and set it's ng-model attribute to formData.id, and whichever value you set it to, the model would have it binded. using a hidden input won't work, as the value attribute doesn't update the angularJS Model assigned via ng-model. Use ng-init instead, to set up the value:
HTML with 2 forms:
<div ng-controller="SearchCtrl" ng-init="formData.id='FORM1'">
<form class="well form-search">
<input type="text" ng-model="formData.title">
<input type="textarea" ng-model="formData.body">
<button ng-click="sendData()">Send!</button>
</form>
</div>
<div ng-controller="SearchCtrl" ng-init="formData.id='FORM2'">
<form class="well form-search">
<input type="text" ng-model="formData.title">
<input type="textarea" ng-model="formData.body">
<button ng-click="sendData()">Send!</button>
</form>
</div>
You can add a hidden field, but it accomplishes nothing - the ng-init attribute does everything you need.
