Pushing both keys and value into an json array structure dynamically - javascript

I have angularjs front end code as follows:
function addController($scope, $http) {
$scope.tableNames = [];
$scope.addNewColumn = function(item) {
$scope.tableNames.push({})
}
}
<html ng-app>
<head>
<title></title>
<meta charset="utf-8" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="addController">
<div class="col-sm-10">
<fieldset ng-repeat="item in tableNames track by $index">
<span> TextBox1:<input type="text" ng-model="item.item1" />
TextBox2:<input type="text" ng-model="item.item2" /></span>
</fieldset>
<button class="btn btn-default" ng-click="addNewColumn()">Add Colname</button>
</div>
<pre>{{tableNames|json}}</pre>
</body>
</html>
So when I enter text in the textbox1 and textbox2 it shows array of below format:
[{
"item1":"textbox1value",
"item2":"textbox2value"
}]
and also when i click addColname button and generate another textbox, values are pushed in different property as follows,it generates:
[{
"item1":"textbox1value",
"item2":"textbox2value"
},
{
"item1":"textbox1value",
"item2":"textbox2value"
}
]
but what actually i need is of structure,
[{
"textbox1value":"textbox2value",
"textbox1value":"textbox2value",
.....
}]
note(:"textboxvalue" are values entered inside textboxes.
somebody help me to get desired output. thanks in advance

This is a working code. I hope this helps :)

Angularjs ng-model in input does not update value in controller

Can anyone explain to me why when I print console.log($scope.inputvalue) the variable is not updated with the values that I enter in the input?
Maybe I just misunderstood the meaning of ng-model, in this case, how do I pass a value from the view to controller?
(function () {
'use strict';
angular.module('LunchCheck', [])
.controller('checkiftoomuch', ['$scope', checkiftoomuch]);
function checkiftoomuch($scope){
$scope.inputvalue = "";
console.log($scope.inputvalue);
}
})();
<!doctype html>
<html lang="en" ng-app="LunchCheck">
<head>
<title>Lunch Checker</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script src="app.js"></script>
<link rel="stylesheet" href="styles/bootstrap.min.css">
<style>
.message { font-size: 1.3em; font-weight: bold; }
</style>
</head>
<body>
<div class="container" ng-controller="checkiftoomuch">
<h1>Lunch Checker</h1>
<div class="form-group">
<input id="lunch-menu"
type="text"
placeholder="list comma separated dishes you usually have for lunch"
class="form-control"
ng-model="inputvalue">
</div>
<div class="form-group">
<button class="btn btn-default">Check If Too Much</button>
</div>
<div class="form-group message">
Total number of disches: {{ inputvalue }}
</div>
</div>
</body>
</html>
You're setting $scope.inputvalue = ""; before the console.log. But after you change the value, you need to console.log it again.
Try using:
function checkiftoomuch($scope){
$scope.inputvalue = "";
console.log($scope.inputvalue);
$scope.$watch('inputvalue', function(newValue, oldValue){
console.log(newValue);
})
}
Or add a function on your button click like:
<div class="form-group">
<button class="btn btn-default" ng-click="showValue()>Check If Too Much</button>
</div>
And in JS:
function checkiftoomuch($scope){
$scope.inputvalue = "";
console.log($scope.inputvalue);
$scope.showValue = function(){
console.log($scope.inputvalue);
}
}
AngularJS has 2-way data binding which means, the values in the view and controller are in sync always, they do not have to be passed back and forth.

ReferenceError angular is not defined

Many times answered, but I still don't understand what's wrong in my code. I'm new to JavaScript and Angular, so please help why I'm getting this error.
Here's my HTML and JavaScript codes. I'm trying to make an array from user input values, show them in table and then insert a button to calculate the cheapest and the most expensive items of the list. Right now I'm stuck in getting the user inputs in the array because of the angular error.
var listaArr = [];
var app = angular.module("ostosLista", []);
app.controller("listaKontrolleri", ['$scope', function($scope) {
$scope.listaArr = [{"syotettyTuote": "syotettyHinta"}];
}]);
var syotettyTuote = $scope.document.getElementById("tuote");
var syotettyHinta = $scope.document.getElementById("hinta");
function lisaaListaanTuote(){
$scope.listaArr.push($scope.syotettyTuote.value);
}
function lisaaListaanHinta(){
$scope.listaArr.push($scope.syotettyHinta.value);

You've used $scope object outside the Controller and the code language is a bit difficult to understand.
However, I've added the simple example from your code.
var listaArr = [];
var app = angular.module("ostosLista", []);
app.controller("listaKontrolleri", ['$scope', function($scope) {
$scope.listaArr = [];
$scope.lisaaListaanTuote = function(){
var val = angular.element(document.querySelector("#tuote")).val();
console.log(val);
$scope.listaArr.push(val);
}
}]);

</html>
in my project , i face problem when i try to edit i fill the input automaticly so the problem is i just get text and all the object in ng-model
for example in the link above if i copy the world Chicken and paste it in input it will not give me the object it will be just text ,
if i insert the world c and choice the option Chicken i will get in ng-model the object (that contain id and name)
Look at working example,
http://plnkr.co/edit/Z930HmH83KIENuEjWhx3?p=preview
I have change your code a bit and made it angular code rather than java script code.
I hope it will work. I have taken your json in .json file and using $http service made call to that json.
var app = angular.module('myApp', ['ui.bootstrap']);
app.factory('autoComplete',function($http){
return{
load:function(){
$http.get('data.json').success(function (data){
sessionStorage.setItem( 'items', JSON.stringify(data) );
})
}
}
})
app.controller('TypeaheadCtrl',function($scope,$http,autoComplete){
$scope.selected = undefined;
$scope.items = JSON.parse(sessionStorage.getItem('items'));
});
I hope that little modification to this solution would take you to your required solution.

It should be ng-bind not ng-binding and it shouldn't be class = ng-binding (angular directives are not css classes) it should be Item name: <h3 ng-bind="item.name"></h3>. Here's an example from the angularJS website:
<script>
angular.module('bindExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.name = 'Whirled';

How to get the autocomplete in angular js?

I have a object which contains name and id.I just want to do the autocomplete based on name.I have tried the code as shown below
//Js file
var app=angular.module("myapp",[]);
app.controller("controller",['$scope',function($scope){
$scope.persons=[
{
Name:"Bhavani",
Id:67
},
{
Name:"Mamata",
Id:66
},
{
Name:"Prasanna",
Id:65
},
{
Name:"Ramya",
Id:64
},
{
Name:"Navya",
Id:63
}
];
$scope.complete=function(){
$("#autocomp").autocomplete({
source: $scope.persons.Id
});
};
}]);
//Html file

<div ng-repeat="p in persons">{{p.Name}}
</div>
<div class="ui-widget">
<input type="text" id="autocomp" ng-keyup="complete()">
</div>
</body>
</html>
The above code may have some errors .Its not getting output which i want to have .Can anyone help me out to solve this problem.
Try like this,
HTML:
<div ng-app = "myapp">
<div ng-controller="controller">
<div class="ui-widget">
<input type="text" id="autocomp" auto-complete>
</div>
</div>
</div>
Js:
var app = angular.module("myapp",[]);
app.controller("controller",function($scope){
$scope.availableTags = [
{
Name:"Bhavani",
Id:67
},
{
Name:"Mamata",
Id:66
},
{
Name:"Prasanna",
Id:65
},
{
Name:"Ramya",
Id:64
},
{
Name:"Navya",
Id:63
}
];
}).directive("autoComplete",function(){
return function(scope,element,attrs){
var names =$.map(scope.availableTags,function(value){ return value.Name;
});
element.autocomplete({
source: names
});
};
});
Working jsbin
This is how you should use any jQuery API's in an AngularJS project (i believe). Anytime you are doing DOM Manipulation or jQuery things, it should be placed inside the link: function() {} via directive.
Probably the main problem with your code was that the source: $scope.persons.Id is just a number. The source needs to be an array of Strings (at least as per the documentation). So I seperated all the names from your persons array and placed them in a new array peopleNames

Angularjs ng-repeat, ng-form and validation error

A simplified version of the code:
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="https://code.angularjs.org/1.4.3/angular.min.js"></script>
<script>
var app = angular.module("main", []);
app.controller("TestController", function($scope) {
$scope.addresses = [{street: ""}, {street: ""}];
$scope.next = function() {
if ($scope.addressMainForm.addressForm.$valid) {
console.log("valid");
} else {
console.log("invalid");
}
$scope.addresses.push({street: ""});
};
$scope.remove = function(index) {
$scope.addresses.splice(index, 1);
};
});
</script>
</head>
<body>
<div ng-controller="TestController" style="width: 500px;">
<form name="addressMainForm">
<div ng-repeat="address in addresses">
<ng-form name="addressForm">
<input ng-model="address.street" required name="street" type="text" placeholder="street" />
<button ng-if="$index > 0" ng-click="remove($index)">REMOVE</button>
</ng-form>
<br>
</div>
</form>
<br>
<button ng-click="next()">NEXT</button>
</div>
</body>
</html>
which looks in the browser like this:
When I click "REMOVE" and then "NEXT" - javascript error is produced:
Error: $scope.addressMainForm.addressForm is undefined
Why is it undefined if there is clearly still one element remaining in the array? Everything otherwise works fine (console.log output), until all the elements are removed but the last one and "NEXT" is clicked.
When you call $scope.addressMainForm.addressForm.$valid , you are attempting to call check to see if the adressForm element is valid, but your remove function has removed the addresses entry associated with that element. So the form indeed still exists, but that call becomes illegal.
Try this:
<!DOCTYPE html>
<html ng-app="main">
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="https://code.angularjs.org/1.4.3/angular.min.js"></script>
<script>
var app = angular.module("main", []);
app.controller("TestController", function($scope) {
$scope.addresses = [{street: ""}, {street: ""}];
$scope.next = function() {
if ($scope.addressMainForm.$valid) {
console.log("valid");
} else {
console.log("invalid");
}
$scope.addresses.push({street: ""});
};
$scope.remove = function(index) {
$scope.addresses.splice(index, 1);
};
});
</script>
</head>
<body>
<div ng-controller="TestController" style="width: 500px;">
<form name="addressMainForm">
<div ng-repeat="address in addresses">
<ng-form name="addressForm">
<input ng-model="address.street" required name="street" type="text" placeholder="street" />
<button ng-if="$index > 0" ng-click="remove($index)">REMOVE</button>
</ng-form>
<br>
</div>
</form>
<br>
<button ng-click="next()">NEXT</button>
</div>
</body>
</html>
