How to button show and hide html form with angular - javascript

I'm still learning to programme.
How I can show and hide two not very different HTML forms with a button in Angular?
I have a code but it shows only two forms and doesn't hide them.
I want to display these two forms on one row. How I can do this?
Please help me.
My HTML code:
<body ng-controller="MainCtrl">
<p>Hello {{name}}!</p>
<button class="btn btn-primary" ng-click="showDiv=true; hideMe()" >Show Div</button>
<button class="btn btn-primary" ng-click="showDiv1=true; hideMe()" >Show Div1</button>
<div ng-show="showDiv">
<div class="col-xl-3">
<div class="form">
<form>
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="database_address">Потребител</label>
<input type="text" class="form-control" required ng-model="activeItem.username" placeholder="Потребителско Име..." />
</div>
<div class="form-group">
<label for="password">Парола</label>
<input type="text" class="form-control" required id="password" ng-model="activeItem.password" />
</div>

Angular code. Maybe it is not very right i think, but you will help me.
Thanks again!
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.hideMe = function(){
console.log('hide the button');
$scope.hide();
}
});

You have to set variable to false(ng-show), and then when user click the button, set variable to true:
Leave ng-click attribute like this:
<button class="btn btn-primary" ng-click="hideDiv()" >Show Div</button>
<button class="btn btn-primary" ng-click="hideDiv1()" >Show Div1</button>
Then:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.showDiv = false;
$scope.showDiv1 = false;
$scope.hideDiv = function(){
if ($scope.showDiv) {
$scope.showDiv = false;
} else {
$scope.showDiv = true;
}
}
$scope.hideDiv1 = function(){
if ($scope.showDiv1) {
$scope.showDiv1 = false;
} else {
$scope.showDiv1 = true;
}
}
});

Here is a demo that may help you get started. Go over the docs for ng-show and ng-click
var app = angular.module("app", []);
app.controller("HelloController", function($scope) {
$scope.message = "Hello, AngularJS";
$scope.showHello = true;
$scope.showBye = false;
$scope.toggleBye = () => {
$scope.showBye = !$scope.showBye;
};
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="HelloController">
<h2 ng-show="showHello">Hello</h2>
<h2 ng-show="showBye">Bye</h2>
<h2>Show always</h2>
<button ng-click="toggleBye()">toggle bye</button>
</div>
</body>

Parameter is not passed to the function on ng-submit

I have a function reset(username) that outputs whatever is entered into the input field of ng-model="username". Why is it not appearing in console though?
This is my function
$scope.reset = function (username) {
console.log(username);
};
and the way I submit the form
<form name="Form" ng-controller="ResetController" ng-submit="reset(username)">
<div>
<div class="row top5">
<label for="username">Username</label>
<div class="col-xs-4">
<input type="text" id="username" placeholder="" maxlength="255"
ng-model="username" required autofocus>
</div>
<div>
<div class="col-xs-5">
<button translate class="btn btn-secondary" type="submit">Reset</button>
</div>
</div>
</div>
</form>
Controller as requested
app.controller("ResetController", function ($scope) {
$scope.username='';
$scope.reset = function (username) {
console.log('username = ', username);
};
});
I believe you do have the ng-app and everything else besides this form, however it is better handled by the DOM if you manipulate your inputs as properties of an object and not directly as $scope. properties. See answers to this here. And note in the code how I attached username to $scope.object.username
var app = angular.module('myApp',[])
app.controller('ResetController',['$scope',function($scope){
$scope.object = {};
$scope.reset = function(username){
console.log(username);
};
}])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<form name="Form" ng-controller="ResetController" ng-submit="reset(object.username)">
<div>
<div class="row top5">
<label for="username">Username</label>
<div class="col-xs-4">
<input type="text" id="username" placeholder="" maxlength="255"
ng-model="object.username" required autofocus>
</div>
<div>
<div class="col-xs-5">
<button translate class="btn btn-secondary" type="submit">Reset</button>
</div>
</div>
</div>
</form>

Undefined Scope in Angujar JS Form issue

I'm having trouble binding form data (which is complete) to my controller. Below is my code:
<form name="form_foto" novalidate>
<div class="form-group">
<label>URL de la foto: </label>
<!--
<input type="text" required class="form-control" placeholder="http://ejemplo.com/foto.jpg">
-->
<input type="text" required class="form-control" placeholder="http://ejemplo.com/foto.jpg" data-ng-model="mifoto.foto" name="foto">
</div>
<div class="form-group">
<label>Lugar: </label>
<input type="text" required class="form-control" placeholder="Lugar de ejemplo" data-ng-model="mifoto.lugar" name="lugar">
</div>
<div class="form-group">
<label>Año: </label>
<input type="text" required class="form-control" placeholder="2016" data-ng-model="mifoto.anio" name="anio">
</div>
<!--
<button class="btn btn-default">Guardar Foto</button>
-->
<button class="btn btn-default" data-ng-disabled="datosNoValidos()" data-ng-click="guardarFoto()">Guardar Foto</button>
</form>
guardarFoto Function code:
$scope.guardarFoto = function(){
alert($scope.mifoto); //comes out undefined
$scope.misFotos.push($scope.mifoto);
delete $scope.mifoto;
}
Any help will be greatly appreciated. Thanks!
Just initialize $scope.mifoto = {}.
Check this live example:
angular.module('app', [])
.controller('ctrl', ['$scope',
function($scope) {
$scope.misFotos = [];
$scope.mifoto = {};
$scope.guardarFoto = function() {
alert($scope.mifoto); //comes out undefined
$scope.misFotos.push($scope.mifoto);
delete $scope.mifoto;
}
}
])

Initialize mifoto outside ur function.
$scope.mifoto = {};

ng-model not updating with input from textbox

This seems like a weird one to me. I have a form for adding vets to a dog walkers' database. I've used ng-model on each field in the form.
<div class="container-fluid" ng-show="nav.page == 'new'" ng-controller="dataController as data">
<div class="row" ng-show="nav.tab == 'vet'">
<div class="col-md-2">
</div>
<div class="col-md-8">
<h1>Add a Vet</h1>
<hr />
<form>
<div class="form-group">
<input type="text" class="form-control" placeholder="Name..." ng-model="data.creator.vet.Name"/>
</div>
<div class="form-group">
<input type="Text" class="form-control" placeholder="Address..." ng-model="data.creator.vet.Address"/>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="Phone Number..." ng-model="data.creator.vet.Phone"/>
</div>
<div class="form-group">
<button class="btn btn-success" ng-click="data.newVet()">Submit</button>
</div>
</form>
</div>
<div class="col-md-2">
</div>
</div>
</div>
Yesterday it was working fine, today it won't update data.creator.vet when I input data. For the life of me, I can't see any problems with it.
The js:
app.controller('dataController', function($http) {
dataCon = this;
this.creator = {};
this.creator.client = {};
this.creator.vet = {};
this.creator.client.Dogs = [];
this.allData = {};
this.newVet = function(){
console.log("New Vet Creating....")
console.log(dataCon.creator)
vet = JSON.stringify(dataCon.creator.vet);
console.log(vet);
$http.get(SERVICE_URL + "?fn=vetCreate&vet=" + vet).then(function(response) {
dataCon.init();
});
}
});

Angular form inputs to array with Validation

Is there a way in angular js to push a list of managers(or any item) to an array with validation in angular. I basically want to create an array as the ng-model and still validate it. Is this possible to do or am i going about it the wrong way?
var app = angular.module("FormTest",[]);
app.controller("AppCtrl", ["$scope", function($scope){
var appCtrl = this;
appCtrl.appName = "Form Array";
$scope.managers = [""];
$scope.form = {};
$scope.form.managers = $scope.managers;
$scope.addManager = function(){
$scope.managers.push('');
}
$scope.removeManager = function(index){
if($scope.managers.length > 1){
$scope.managers.splice(index, 1);
}
}
}])
angular.element(document).ready(function(){
angular.bootstrap(document.querySelector('html'), ["FormTest"]);
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<div ng-controller="AppCtrl as app">
<h2>{{app.appName}}</h2>
<div>
{{form.managers}}
<div>
<div>{{managers}}</div>
<div class="btn btn-primary" ng-click="addManager()">add manager</div>
</div>
</div>
<form novalidate name="form">
<div class="form-group" ng-repeat="item in managers track by $index">
<div class="row-fluid">
<div class="col-md-5">
<input type="text" ng-model="managers[$index]" ng-pattern="/\w{3,}/" required class="form-control">
</div>
<div class="col-md-1">
<div class="btn btn-default">
<span class="glyphicon glyphicon-remove-circle" ng-click="removeManager($index)"></span>
</div>
</div>
</div>
</div>
</form>
</div>
In your example, all right, except for that of the regular expression.
Look at the example code jsfiddle.
<h2>{{app.appName}}</h2>
<div>
{{form.managers}}
<div>
<div>{{managers}}</div>
<button class="btn btn-primary" ng-click="addManager()">add manager</button>
</div>
</div>
<form novalidate name="form">
Form valid={{form.$valid|json}}
<div class="form-group" ng-repeat="item in managers track by $index">
<div class="row-fluid">
<div class="col-md-5">
<input type="text" ng-model="managers[$index]" name="manager{{$index}}" ng-pattern="/^\w{3,}$/" required class="form-control">
{{form['manager'+$index].$error}}
</div>
<div class="col-md-1">
<div class="btn btn-default">
<button class="glyphicon glyphicon-remove-circle" ng-click="removeManager($index)">Remove</button>
</div>
</div>
</div>
</div>

ngSubmit not getting submitted

I am pretty much beginner with AngularJS, and I am trying to submit a form, as follows:
<div ng-include="APP_URL + '/view/myResolver/searchForm.html'" ng-controller="MySearchFormController"> </div>
This is my searchForm.html:
<div class="container">
<div class="row">
<div class="col-md-14">
<div class="well">
<div class="col-md-9">
<form ng-submit="submit()" class="form-horizontal clearfix" role="form" >
<div class="form-group">
<label for="teamName" class="col-md-3 control-label">Team name</label>
<div class="col-md-9">
<input type="text" ng-model="myName" id="myName" class="form-control">
</div>
</div>
</div>
<div class="row">
<div class="col-md-0"></div>
<button ng-click="onFormReset()" class="btn btn-default">Reset</button>
<input type="submit" id="submit" class="btn btn-primary" value="Search"/>
</div>
</form>
{{teamName}}
</div>
</div>
</div>
UPDATE
Controller:
angular.module('MyApp')
.controller('MySearchFormController', ['$scope', function($scope){
$scope.submit = function (){
if ($scope.myName) {
alert($scope.myName);
$scope.teamName = this.teamName;
}
}
}]);
What is currently happening is the text is automatically appearing in the {{teamName}} field.
Instead, I would like to make it work only onSubmit(), namely clicking the Search button.
You can try like this :
function demo ($scope) {
$scope.submit = function () {
$scope.submitted = true;
};
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="demo">
<form ng-submit="submit()">
<input type="text" ng-model="teamName">
<button>Submit</button>
</form>
<p ng-if="submitted">{{ teamName }}</p>
</div>
BUT it is not optimal, as once you submitted one time, $scope.submitted is true and you will get the same problem, again.
SO, I would recommend you to not bind your {{ teamName }} to the same reference as the input :
function demo ($scope) {
$scope.submit = function () {
$scope.teamNameCopy = angular.copy($scope.teamName);
};
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="demo">
<form ng-submit="submit()">
<input type="text" ng-model="teamName">
<button>Submit</button>
</form>
<p>{{ teamNameCopy }}</p>
</div>
OK, the issue is resolved.
Unfortunately, that was an issue related to incorrectly closing html tags, and not
