I have the following to create a job with a position and multiple requirements Plunker example:
<div ng-controller="MainCtrl as vm">
<div>Position: <span data-ng-bind="vm.job.position"></span></div>
<br/>
<form name="form" data-ng-submit="vm.create(job)">
<label for="position">Enter the Position</label>
<input id="position" name="vm.job.position" type="text" data-ng-model="vm.job.position" />
<div>
<br/>
Requirements:
<br/>
<ul>
<li data-ng-repeat="r in vm.job.requirements">{{r.name}}</li>
</ul>
<input id="name" name="requirement.name" type="text" data-ng-model="requirement.name" />
<input type="button" value="Add Requirement" class="button" data-ng-click="vm.addRequirement(requirement)"/>
</div>
<br/><br/>
<button>Create Job</button>
</form>
</div>
the controller
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
var vm = this;
vm.job = { position: '', requirements: [] };
vm.create = function (job) {
alert("job created");
}
vm.addRequirement = function (requirement) {
vm.job.requirements.push(requirement);
}
});
When I add a requirement I see it on the list but when I try to add a new one, the one that is already in the list start to change. I do not want that. I want to add a new one to the list.
Finally, when I submit the form using "Create Job" is where I will send all the Job data to the API.
The problem is with your addRequirement function, because you are adding the same object to the list (and that's the reason your item changes the name when you edit the input box).
To make your example work as intended you should push a clone of the requirement object (see documentation).
vm.addRequirement = function (requirement) {
vm.job.requirements.push( angular.copy(requirement) );
}
The easiest way to do this, is simply use ng-model on the input that you would like to append to your list. Then you can easily access it from the controller.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
var vm = this;
vm.job = { position: '', requirements: [] };
function create(job) {
alert("job created");
}
function addRequirement() {
vm.job.requirements.push(vm.currentRequirement);
}
vm.create = create;
vm.addRequirement = addRequirement;
});
and in the html:
<input type="button" value="Add Requirement" ng-click="vm.addRequirement()"/>

I'm a beginner of AngularJS, and I cannot solve the problem of the title. If we push the button changeText in the following code, the text of the textarea will change. But this event doesn't happen if we push the button changeTextNew which is added by pushing another button addNewButton`.
html
<div ng-app="app" ng-controller="MainCtrl">
<input name="widget.title" ng-model="widget.title"><br>
<input type="button" ng-click="setText()" value="changeText"><br>
<input type="button" id="piyo" value="addNewButton">
<div id="fuga"></div>
</div>
js
angular.module('app', [])
.controller('MainCtrl', function($scope) {
$scope.widget = { title: 'before' };
$scope.setText = function() {
this.widget.title = "after"
}
});
$(document).on('click', '#piyo', function() {
$('#fuga').append("<input type='button' ng-click='setText()' value='changeTextNew'><br>")
})

Try to avoid using jQuery together with AngularJS.
Try this:
angular.module('app', [])
.controller('MainCtrl', function($scope, $compile) {
$scope.widget = { title: 'before' };
$scope.setText = function() {
this.widget.title = "after"
}
$(document).on('click', '#piyo', function() {
$("#fuga").append($compile("<input type='button' ng-click='setText()' value='changeTextNew'><br>")($scope));
});
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="MainCtrl">
<input name="widget.title" ng-model="widget.title"><br>
<input type="button" ng-click="setText()" value="changeText"><br>
<input type="button" id="piyo" value="addNewButton">
<div id="fuga"></div>
</div>
I've got a problem related to the visibility of a button. I have to hide a button when there is no text in the form field, and show it back when it's filled. I've got some code:
<div class="TextAreaCont">
<input ng-model="pageUrl" placeholder="Facebook Page URL" type="text">
</div>
<div class="ButtonCont" ng-show="ctrl.isButtonVisible()">
<button ng-click="ctrl.send()">Fetch data</button>
</div>
And I wrote it:
Facebook.controller('PageCtrl', ['$scope', function($scope){
$scope.isButtonVisible = function(){
if($scope.pageUrl){return true}else{return false}
};
Where is the problem?
To be honest, I've never leart JS and Angular.
Here is my solution
var Facebook = angular.module('Facebook', []);
Facebook.controller('PageCtrl', [function(){
var ctrl = this;
ctrl.isButtonVisible = function(){
if(ctrl.pageUrl){
return true;
}else{
return false;
}
};
ctrl.send = function(){
console.log('Page URL: ' + ctrl.pageUrl)
};
}]);
See Plunker for more details.
Few problems that I can spot in your original code:
when using controller as syntax, use 'this' keyword, not $scope inside your controller
ng-model="pageUrl" should be ng-model="ctrl.pageUrl"
Just FYI, isButtonVisible() will be evaluated on every digest cycle, so there no need for watchers of ng-change.
try this.
i put simple example.
var app = angular.module('app', []);
app.controller('TestController', function ($scope) {
$scope.display = false;
$scope.isButtonVisible = function(pageUrl){
if(pageUrl){
$scope.display = true;
}
else{$scope.display = false;}
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="TestController">
<input ng-model="pageUrl" placeholder="Facebook Page URL" type="text" ng-change="isButtonVisible(pageUrl)">
<div class="ButtonCont" ng-show="display">
<button ng-click="send()">Fetch data</button>
</div>
<input ng-model="pageUrl2" placeholder="Facebook Page URL" type="text" ng-change="isButtonVisible(pageUrl)">
<div class="ButtonCont" ng-show="pageUrl2">
<button ng-click="send()">Fetch data</button>
</div>
</div>
I have two textarea, I want to use the content on the first to update the second immediately the user clicks the textarea using ng-change. Bt when I click on the textarea, no update is made. Below is the two textarea
<textarea ng-change="content=emojiMessage.messagetext | colonToCode" placeholder="emoji..." ng-bind="emojiMessage.messagetext | colonToCode" id="messageInput"></textarea>
<input ng-hide="false" type="text" id="message" name="message" ng-model="content" value="{{content}}" />
What could be wrong?
Now the snippet is using ng-focus instead, but with the same function.
var app = angular.module('myApp', []);
app.filter('colonToCode', function(){
return function (data) {
return data + ' Something added by the filter';
};
});
app.controller('ctrl', function($scope, $filter) {
$scope.content = 'Something';
$scope.emojiMessage = {
messagetext: 'smilie face'
};
$scope.setContent = function(text){
$scope.content = $filter('colonToCode')(text);
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="ctrl">
<textarea ng-focus="setContent(emojiMessage.messagetext)" placeholder="emoji..." ng-model="emojiMessage.messagetext" id="messageInput"></textarea>
<input ng-hide="false" type="text" id="message" name="message" ng-model="content" value="{{content}}" />
</div>
</div>
This is my script file
app.controller('userController', function PostController($scope, userFactory) {
$scope.users = [];
$scope.user = { items : [] };
$scope.editMode = false;
$scope.addItem = function () {
$scope.user.items.push({
Name: $scope.newItemName,
Value: $scope.newItemValue
});
};
$scope.deleteItem = function (index) {
$scope.user.items.splice(index, 1);
};}
This is my html file.
<div class="form-group">
<ul class="nav">
<label for="title" class="col-sm-2 control-label">Items</label>
<div class="col-sm-10">
<input type="text" value="ItemName" class="form-control" id="title" ng-model="newItemName" required placeholder="name of new item...">
<input type="text" value="ItemName" class="form-control" id="title" ng-model="newItemValue" required placeholder="name of new item...">
</div>
<button ng-click="addItem()">Add Me</button>
<li ng-repeat="item in user.items">
{{item.Name}} <a ng-click="deleteItem($index)" class="delete-item">x</a>
</li>
</ul>
</div>
When I Click add me button i get an error as
TypeError: Cannot read property 'items' of undefined
I cant figure out the error and why it occurs. Please help me I'm new to angular js
The error occurs because your user property is null:
$scope.user = null;
Change it to an actual object which ideally has items property:
$scope.user = { items : [] };
Simple where is items if you have $scope.user = null;
so simple do one thing add
$scope.user = {items:[]};
and then use $scope.user.items.push(data)
i want to create a page where someone adds 1 or more locations to a contact and right now i have something that looks like this.
<div class="input-append" ng-repeat="location in newPartner.partner_location">
<input class="input-large" type="text" ng-model="location">
<button class="btn" type="button" ng-click="delLocation1({{$index}})">- {{$index}}</button>
</div>
<div class="input-append">
<input class="input-large" type="text" ng-model="new_location">
<button class="btn btn-primary" type="button" ng-click="addLocation1()">+</button>
</div>
This is the HTML and the controller looks like this.
$scope.newPartner = {'partner_name':'newname','partner_location':['X','Y','Z']};
$scope.addLocation1 = function() {
$scope.newPartner.partner_location.push($scope.new_location);
$scope.new_location = "";
}
$scope.delLocation1 = function(id) {
$scope.newPartner.partner_location.splice(id, 1);
}
Now it works great on begin but if i delete some items and add some it suddenly bugs out and starts to delete the previous item instead the one i press - (minus) on.
Is there something i did wrong? Thank you in advance, Daniel!
First off remove {{}} from ng-click="delLocation1({{$index}})". It should be:
ng-click="delLocation1($index).
Second, I suggest you to add some basic debugger to see what happens with our model when we add new value: <pre>{{newPartner.partner_location|json}}</pre>
Third, I would change the model to:
$scope.newPartner = {
'partner_name': 'newname',
'partner_location': [{value:'X'}, {value:'Y'}, {value:'Z'}]
};
because, by this way: ['X','Y','Z'] we can't modify our data.
Demo Fiddle
Finally this is our fixed code:
HTML
<div ng-controller="fessCntrl">
<div ng-repeat="location in newPartner.partner_location">
<input class="input-large" type="text" ng-model="location.value">
<button class="btn" type="button" ng-click="delLocation1(newPartner.partner_location, $index)">{{$index}}</button>
</div>
<div class="input-append">
<input class="input-large" type="text" ng-model="new_location">
<button class="btn btn-primary" type="button" ng-click="addLocation1()">+</button>
</div>
<pre>{{newPartner.partner_location|json}}</pre>
</div>
JS
var fessmodule = angular.module('myModule', []);
fessmodule.controller('fessCntrl', function ($scope) {
$scope.new_location = "empty";
$scope.newPartner = {
'partner_name': 'newname',
'partner_location': [{value:'X'}, {value:'Y'}, {value:'Z'}]
};
$scope.addLocation1 = function () {
$scope.newPartner.partner_location.push({value:$scope.new_location});
$scope.new_location = "empty";
}
$scope.delLocation1 = function (locations, index) {
locations.splice(index, 1);
}
});
fessmodule.$inject = ['$scope'];
