Consider the following JS
angular.module('myApp')
.controller('HeaderCtrl', function($scope) {
$scope.searchBooking = "test";
$scope.goToBooking = function() {
console.log($scope.searchBooking);
//$location.path('/bookings/' + $scope.searchBooking);
//delete($scope.searchBooking);
}
$scope.printValue = function() {
console.log($scope.searchBooking);
}
}
);
And the following HTML
<div class="input-group custom-search-form">
<input type="text" class="form-control" placeholder="Testing" ng-model="searchBooking" ng-change="printValue()">
<span class="input-group-btn">
<button class="btn btn-default" type="button">
<i class="fa fa-search"></i>
</button>
</span>
</div>
My problem is that when the page loads, "test" is written in the text field, but when I change the field or press the button, nothing happens (console says "test" on every change or button click. Anyone know what I did wrong?
Try to wrap the value in an object. Objects are passed by reference, but simple values are passed as a copy of that value. It happened to me too several times.
Try this approach
$scope.myObject.searchBooking = "test"
So the full code will look like this
angular.module('myApp')
.controller('HeaderCtrl', function($scope) {
$scope.myObject.searchBooking = "test";
$scope.goToBooking = function() {
console.log($scope.myObject.searchBooking);
//$location.path('/bookings/' + $scope.myObject.searchBooking);
//delete($scope.myObject.searchBooking);
}
$scope.printValue = function() {
console.log($scope.myObject.searchBooking);
}
}
);
and the html
<input type="text" class="form-control" placeholder="Testing" ng-model="myObject.searchBooking" ng-change="printValue()">
Find this fiddle which is having ng-model binding in ng-change.
HTML
<div ng-controller="MyCtrl">
<div class="input-group custom-search-form">
<input type="text" class="form-control" placeholder="Testing" ng-model="searchBooking" ng-change="printValue()">
<span class="input-group-btn">
<button class="btn btn-default" type="button">
<i class="fa fa-search"></i>
</button>
</span>
</div>
</div>
Angular controller
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.searchBooking = "test";
$scope.goToBooking = function() {
console.log($scope.searchBooking);
//$location.path('/bookings/' + $scope.searchBooking);
//delete($scope.searchBooking);
}
$scope.printValue = function() {
console.log($scope.searchBooking);
}
}

I'm trying to pass the value of the ng-model="alertThreshold.value" but when I click on <a class="spin-up" data-spin="up" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-up"></i></a> or <a class="spin-down" data-spin="down ng-click = "getAlertThreshold(alertThreshold.value)"" ><i class="fa fa-caret-down"></i></a>
it just call the function without updating the value, the value is always = 10.
<div class="input-group spinner" data-trigger="spinner">
<input type="text" class="form-control text-center" value="0" data-rule="quantity" ng-model="alertThreshold.value" min="0" max="50" ng-change ="getAlertThreshold(alertThreshold.value)">
<div class="input-group-addon">
<a class="spin-up" data-spin="up" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-up"></i></a>
<a class="spin-down" data-spin="down" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-down"></i></a>
</div>
</div>
and in my controller:
$scope.alertThreshold = {
value: 10
};
$scope.getAlertThreshold = function(value){
console.log("value:",value)
$scope.alertThreshold.value = value;
}
ng-click = "getAlertThreshold(++alertThreshold.value)" ng-click = "getAlertThreshold(--alertThreshold.value)" may resolve the issue.
The value of $scope.alertThreshold.value is always the same because take the value of the input. It's like $scope.alertThreshold.value = $scope.alertThreshold.value every ng-click or ng-change
In my project I need to add dynamic amount of datepickers to the page.
I tried to do it this way (Plunker):
Script:
var app = angular.module('plunker', ['ui.bootstrap']);
app.controller('MainCtrl', function($scope) {
$scope.openDatePicker = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
$scope.dateOptions = {
formatYear: "yy",
startingDay: 1,
format: "shortDate"
};
$scope.details = [{
"parameterValue": "2015-08-12"
}, {
"parameterValue": "2015-08-12"
}, {
"parameterValue": "2015-08-12"
}, {
"parameterValue": "2015-08-12"
}];
});
HTML:
<!DOCTYPE html>
<html ng-app="plunker">

<div ng-controller="MainCtrl">
<form name="detailsForm" novalidate ng-submit="submitForm(detailsForm.$valid)">
<div ng-repeat="item in details" class="input-group">
<input ng-model="item.parameterValue" type="text" class="form-control" id="datePickerItem" datepicker-popup="shortDate"
is-open="opened" datepicker-options="dateOptions" current-text="Today" clear-text="Clear" close-text="Close" ng-readonly="false" />

</span>
</div>
</form>
</div>
</body>
</html>
The problem is that when I try to open one datepicker, all of them are opened (logically, as they share the same $scope.opened variable). Also when I close them and try to open them again, nothing happens.
Is there a elegant way to achieve this?
Thanks.
All of your datepickers have id="datePickerItem".
The id attribute must be unique in html. Try this instead:
id="datePickerItem_{{$index}}"
This will add the ng-repeat's current index to the id, so you can be relatively certain your id's are unique. This should also prevent all the datepickers from opening at the same time.
Also, you're using one and the same opened variable for all datepickers.
Try this instead:
<div ng-repeat="item in details" class="input-group">
<input ng-model="item.parameterValue" type="text" class="form-control"
id="datePickerItem_{{$index}}" datepicker-popup="shortDate"
is-open="opened[$index]" datepicker-options="dateOptions" current-text="Today"
clear-text="Clear" close-text="Close" ng-readonly="false" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="openDatePicker($event, $index)">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</div>
And:
$scope.opened = [];
$scope.openDatePicker = function($event, index) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened[index] = true;
};
Just make sure you set $scope.opened[index] to false, in case you close the datepicker.
try this:
$scope.open = function($event,opened) {
$event.preventDefault();
$event.stopPropagation();
$scope[opened] = true;
};
and in your html
ng-click="open($event, 'nameOfYourModel')"
why not bind opened on the repeat object?
like:
<div ng-repeat="item in details" class="input-group">
<input ng-model="item.parameterValue" type="text" class="form-control"
id="datePickerItem_{{$index}}" datepicker-popup="shortDate"
is-open="item['opened']" datepicker-options="dateOptions" current-text="Today"
clear-text="Clear" close-text="Close" ng-readonly="false" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="openDatePicker($event, item)">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
and in controller:
$scope.openDatePicker = function($event, item) {
$event.preventDefault();
$event.stopPropagation();
if(item.opened){
item.opened = !item.opened;
} else{
item.opened = true;
}
};
I'm stuck with this simple form submission. I feel that everything is right, but it doesn't work.
My html :
<html ng-app = 'myApp'>
<div ng-controller="Tabs">
...
<form ng-submit="sendClicked()" >
<div class="input-group">
<input type="text" class="form-control" ng-model="text"/>
<span class="input-group-btn" >
<button class="btn btn-info" type="submit">SEND</button>
</span>
</div>
</form>
...
</div>
</html>
My app.js :
myApp.controller('Tabs', function ($scope) {
$scope.sendClicked = function () {
console.log('can reach here');
if($scope.text) {
socket.emit('send message', $scope.text);
$scope.text = null;
}
};
});
Must be input type submit, but you have button, that doesn't ever have type attribute property
I get an error when I run the following code to reset my form:
$scope.saveFormData = function () {
$scope.testForm.$setPristine();
}
And HTML:
<form name="testForm" >
<label class="item item-input item-stacked-label">
<span class="input-label">Title</span>
<input type="text" ng-model="formData.shortDesc" required="">
</label>
<button class="button button-block button-positive" type="submit" ng-click="saveFormData()" >Opslaan </button>
</form>
It works fine, here is the JSFiddle, try to add the condition if the form exists, but I don't know what error you get:
function MyCtrl($scope) {
$scope.saveFormData = function() {
if ($scope.testForm) {
$scope.testForm.$setPristine();
$scope.formData = {};
}
};
}
The following code-snippet enables me to edit the elements on a page, however, clicking on the P tags all the others change into inline-editor mode as well. How can I rework this script, such that it only enables the editor for the P tag clicked?
JS code:
function Profile($scope) {
$scope.person = {
name : "Test Name",
company : "Test",
role : "Test Role"
};
}
function Editor($scope) {
$scope.editorEnabled = false;
$scope.enableEditor = function() {
$scope.editorEnabled = true;
$scope.name = $scope.person.name;
$scope.company = $scope.person.company;
$scope.role = $scope.person.role;
},
$scope.disableEditor = function() {
$scope.editorEnabled = false;
},
$scope.save = function() {
$scope.person.name = $scope.name; //var = input.value
$scope.person.company = $scope.company;
$scope.person.role = $scope.role;
$scope.disableEditor();
}
}
HTML:
<div ng-controller="Profile">
<div ng-controller="Editor">
<h1 class="center" ng:hide="editorEnabled" ng:click="enableEditor()">{{person.name}}</h1>
<span ng:show="editorEnabled">
<form class="form-inline">
<input type="text" size="30" name="name" ng:required ng-model="name">
<button class="btn btn-success" ng:click="save()">Ok</button>
<button class="btn btn-warning" ng:click="disableEditor()">Cancel</button>
</form>
</span>
<h5 class="center" ng:hide="editorEnabled" ng:click="enableEditor()">{{person.role}} # {{person.company}}</h5>
<span ng:show="editorEnabled">
<form class="form-inline">
<input type="text" size="30" name="role" ng:required ng-model="role"> # <input type="text" size="30" name="company" ng:required ng-model="company">
<button class="btn btn-success" ng:click="save()">Ok</button>
<button class="btn btn-warning" ng:click="disableEditor()">Cancel</button>
</form>
</span>
</div>
</div>
The way I would most likely approach it would be to introduce new field into $scope that identifies which field is editable. Then your ngShow directive would contain an expression, something along these lines:
<span ng:show="editable == 'company'">
Your ngClick directive would look something like this:
<h1 ng:click="editor = 'company'">
Your cancel button would set this to null and your enable/disable editor functions would be gone. Bear in mind all this is top of my head, hopefully it points you in the right direction. I'll improve this answer if I get a chance.
