First of all, I want to say that I am beginner with angularjs :D
My problem is:
I'm trying add the keypress event when user goes to edit the value in cell on angular ui-grid.
In the beginning it seems to work, but when I finish editing a cell and mute the focus the value disappears.
Here is the link to see the event running: https://plnkr.co/edit/vw8W6PqFt11nt4BDhWu9
And here is my code:

});
}]);
app.directive('numbersOnly', function () {

var transformedInput = text.replace(/[^0-9]/, '');
if (transformedInput !== text) {
ngModelCtrl.$setViewValue(transformedInput);
ngModelCtrl.$render();
}
return transformedInput;
}
return undefined;
}
ngModelCtrl.$parsers.push(fromUser);
}
};
});
}());
File: cell-template.html
<div>
<form name="inputForm">
<input type="text"
ui-grid-editor
ng-model="someValue"
data="row.entity.someValue"
ng-class="'colt' + col.uid"
numbers-only />
</form>
</div>
I need this functionality with keypress event only. How do I update the model with the input field value ?
Thanks.
The problem is that your column value is not correctly bound to the ngModel in the cell template.
The correct value would be to use the MODEL_COL_FIELD which you can read more about in the wiki, look at section "Editable Cell Templates"
Update your cell-template.html to
<div>
<form name="inputForm">
<input type="text"
ui-grid-editor
ng-model="MODEL_COL_FIELD"
ng-class="'colt' + col.uid"
numbers-only />
</form>
</div>

I have a problem using a directive to capitalize input for a field in my form.
I am using a directive I found on SO that does the trick well when the user interacts with the field. The problem I have is that when data comes in, like it is set from the controller, the directive doesn't run. Even if the field is touched and focus leaves!
Here is the plunker : http://plnkr.co/edit/ugrurqAVraRqiJQmDZG7?p=preview
DIRECTIVE
var app = angular.module('plunker', []);
app.directive('capitalize', function() {
return {
require: 'ngModel',
link: function(scope, element, attrs, modelCtrl) {
var capitalize = function(inputValue) {
if (inputValue === undefined) inputValue = '';
var capitalized = inputValue.toUpperCase();
if (capitalized !== inputValue) {
modelCtrl.$setViewValue(capitalized);
modelCtrl.$render();
}
return capitalized;
}
modelCtrl.$parsers.push(capitalize);
capitalize(scope[attrs.ngModel]); // capitalize initial value
}
};
});
app.controller('MyCtrl', function($scope,$filter) {
$scope.second = "capitalizeme"
});
TEMPLATE
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<script data-require="angular.js#1.5.0" data-semver="1.5.0" src="https://code.angularjs.org/1.5.0/angular.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MyCtrl">
<div>
<label>Input 2</label>
<input capitalize type="text" ng-model-options="{ updateOn: 'blur' }" ng-model="second" />{{second}}
</div>
</body>
</html>
You can see that if you type in the field and leave, it will capitalize the whole thing. I tried to use setTouched(); to trigger the validation but that isn't working either.
My most promising solution so far is to use a filter. Here is the plunker:
http://plnkr.co/edit/Y9VaxGFjHfun9e6uIrtZ?p=preview
In controller,
var app = angular.module('plunker', []);
app.controller('MyCtrl', function($scope,$filter) {
$scope.second = "capitalizeme";
$scope.$watch('second', function (val) {
$scope.second = $filter('uppercase')(val);
}, true);
});
In template:
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<script data-require="angular.js#1.5.0" data-semver="1.5.0" src="https://code.angularjs.org/1.5.0/angular.js"></script>

<div>
<label>Input 2</label>
<input type="text" ng-model-options="{ updateOn: 'blur' }" ng-model="second" />{{second}}
</div>
</body>
I started looking into angular and cannot seem to figure out why my data is not passed to my directive. I have code here: https://plnkr.co/edit/ONwYevQ4NbvBVjTwARHl?p=preview
My Code:
app.js:
var app = angular.module('mjApp', []);
app.controller('MainController', ['$scope', '$http', function ($scope, $http) {
$scope.name = "m.jacionis";
$scope.avatar = null;
$scope.fetchData = function(){
var callUrl = 'https://api.github.com/search/users?q=' + $scope.name;
$scope.avatar = "http://images.clipartpanda.com/sad-face-clipart-black-and-white-9c4eqRyyi.png";
$http({
method: 'GET',
url: callUrl
}).then(function successCallback(response) {
$scope.avatar = response.data.items.length > 0 ?
response.data.items[0].avatar_url : $scope.avatar;
console.log($scope.avatar);
}, function errorCallback(response) {
console.log('avatar stays the same');
});
};
}]);
app.directive("mjDirective", function(){
return {
restrict: "EA",
templateUrl: 'template.html',
scope: {
name: "=name",
avatar: "=avatar"
}
};
});
index.html:
<!DOCTYPE html>
<html ng-app="mjApp">
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body>
<div class="parent" ng-controller="MainController">
<div class="line">
<input type='text' ng-model='name' />
<input type="button" ng-click="fetchData()" value="Submit User Name" />
</div>
<mj-directive name=name userAvatar=userAvatar></mj-directive>
</div>
</body>
</html>
template.html:
<div class='line'>
<p>Name : <strong>{{name}}</strong></p>
<img class="avatar" src={{avatar}}/>
</div>
name value is passed, but avatar value which I get when I fetch data isn't. I cannot seem to figure out, why it is like that. Any ideas or suggestions would help a lot.
I think you have taken wrong name userAvatar instead of avatar since you binded avatar
your bindings,
scope: {
name: "=name",
avatar: "=avatar"
}
So, you have to take name and avatar in directive.
<body>
<div class="parent" ng-controller="MainController">
<div class="line">
<input type='text' ng-model='name' />
<input type="button" ng-click="fetchData()" value="Submit User Name" />
</div>
<mj-directive name=name avatar=avatar></mj-directive>
</div>
</body>
change directive,
<mj-directive name=name avatar=avatar></mj-directive>
I think you need to wrap the name and avatar in strings when you use them in HTML.
<mj-directive name="name" userAvatar="userAvatar"></mj-directive>
Also inside the directive you should have:
scope: {
user: "=name"
avatar: "=userAvatar"
}
Got a questions regarding the select option value, i can get the value as the select options changed, but i am not able to get the value of the select options thru the search button, it will just give a value undefined. So where is the problem?
index.html
<div ng-controller="MatIncListCtrl">
<button class="fluid labeled icon blue ui button top attached"><i class="ellipsis vertical icon"></i>Toggle Filters Pane</button>
<div class="ui attached segment" uib-collapse="isCollapsed">
<form role="form" class="ui form">
<div class="fields">
<div class="twelve wide field" ng-controller="DistinctSupplierCtrl">
<label>Supplier</label>
<select ng-model="Supplier" class="ui fluid dropdown" ng-options="x.supp_no as x.supp for x in data" ng-change="selectAction()">
<option></option>
</select>
</div>
</div>
</form>
<br />
<button type="button" class="ui orange fluid labeled icon button" tabindex="0" ng-click="FindMatInc()"><i class="search icon"></i>Search</button>
</div>
</div>
controller.js
.controller('DistinctSupplierCtrl', function($scope, $http) {
$scope.selectAction = function() {
console.log($scope.Supplier);
};
var xhr = $http({
method: 'post',
url: 'http://localhost/api/list-distinct-supp.php'
});
xhr.success(function(data){
$scope.data = data.data;
});
})
.controller('MatIncListCtrl', function ($scope, $http) {
$scope.FindMatInc = function (){
console.log($scope.Supplier);
}
});
If you want to access a value from a scope, you've got to make sure it's in that scope or in the scope of it's ancestors. Now your ng-model is declared in the child scope. If you want to access it from the parent scope, you'll need to declare it in the parent scope. That way when the model get changed, it changed in the parent scope and thus accessible in both scopes:
Working example:
angular.module('App', []);
angular.module('App').controller('ControllerParent', [
'$scope',
function ($scope) {
// Model value declared in parent scope
$scope.selected = {};
}
]);
angular.module('App').controller('ControllerChild', [
'$scope',
function ($scope) {
$scope.options = [{
id: 1,
name: 'Alpha'
}, {
id: 2,
name: 'Bravo'
}, {
id: 3,
name: 'Charlie'
}, {
id: 4,
name: 'Delta'
}];
}
]);

Failing example:

angular.module('App').controller('ControllerParent', [
'$scope',
function ($scope) {}

angular.module('App').controller('ControllerChild', [

Descendant scopes have access to the values of their ancestors. Ancestors don't have access to values of their descendants.
Another way to work on nested controllers using the controller as syntax.
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>AngularJS Tutorial</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script>
angular.module('app', []);
angular.module('app').controller("MainController", function(){
var vm = this; //The vm in this case means viewmodel
vm.title = 'AngularJS Nested Controller Example';
});
angular.module('app').controller("SubController", function(){
var vm = this;
vm.title = 'Sub-heading';
});
</script>
</head>
<body ng-app='app' ng-controller='MainController as main'>
<div class='container'>
<h1>{{main.title}}</h1>
<div ng-controller='SubController as sub'>
<h2>{{sub.title}}</h2>
<p>If we were not using the <strong>ControllerAs</strong> syntax we would have a problem using title twice!</p>
</div>

Why I'm not able to console output $scope values ? I'm trying to extract user assigned values from the pages and retrieve in controller. Eventually i would like to pass this to service so multiple controllers can access these data.

$scope.lower = function(){
return $filter('lowercase')($scope.name);
}
$scope.name = $scope.lower();
console.log($scope.name);
console.log($scope.lower());
}]);
Console will output values upon initializing but not after user make changes.
You need to watch the scope variable:
$scope.$watch('name', function() {
console.log($scope.name);
});
More information: https://stackoverflow.com/a/15113029/5787736
Just a more "functional" version. Everyone is right, you are logging the observable, not what was observed. What you want is for console.log to be called on each change to $scope, not called once (as you have it now).
$scope.$watch("name", console.log);
You're logging only from the constructor. If you want to log each time something changes, consider a watch:
$scope.$watch("name", function() {
console.log($scope.name);
}
Why would you expect a controller to be rerendered when a scope variable changes? You can use scope watchers or input event listeners to listen for changes.
Here's an example with a watcher:
var myApp = angular.module('myApp', []);
myApp.controller('mainController', ['$scope', '$filter', function($scope, $filter) {
$scope.name = 'Test ';
$scope.lower = function(){
return $filter('lowercase')($scope.name);
}
$scope.name = $scope.lower();
console.log($scope.name);
console.log($scope.lower());
$scope.$watch('name', function() {
console.log($scope.name);
console.log($scope.lower());
});
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" class="container">
<div ng-controller="mainController">
<h1>Hello world!</h1>
<label>Please enter something</label>
<input textarea ng-model="name" />
<h4> This is what you entered : {{ name }} </h4>
<h4 style=color:red> now filtering: {{ lower() }}</h4>
</div>

Im basic developer , just wanted to pass hidden values from my html page in a json array . Following is my code :-
Index.html
<!doctype html>
<html ng-app="plunker" >
<head>
<meta charset="utf-8">
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');
</script>
<link rel="stylesheet" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" novalidate>
<b> Text: </b>
<input ng-model="form.text" required /><br>
<button ng-click="submitForm()" bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</body>
</html>
app.js
var app = angular.module('myApp');
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
Now , the value from ng-model="form.text" successfully returns the result as for unhidden input types
{ "text":"What_ever_text" }
but how to send a defined value in array, consisting of hidden input type like :-
<input value="99999" type="hidden" ng-model="form.userid" required />
So , wanted desired output like :-
{ "text":"What_ever_text" , "userid":"99999" }
any solution ?
Note :- The input type should be hidden or any other easier method appreciated. Thanks in advance.
hidden input fields also works same as normal fields only.
see the below code
var app = angular.module('myApp', []);
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {
text: "some test",
userid: '12312312312'
};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">

<br/>
<input type="hidden" ng-model="form.userid" required />
<button bng-disabled="myForm.$invalid">Click Me!</button>
</form>
