I want the first typed letter turn into a capital letter, but struggeling with Angular. Maybe it is a little detail that I missed out, so a fresh eye to look at this would be helpful.
var app = angular.module("todoApp", []);
app.filter("NameInput", function(){
return function(input, scope){
if (input!=null)
input = input.toLowerCase();
return input.substring(0,1).toUpperCase()+input.substring(1);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<body ng-app="todoApp" ng-cloak>
<div id="wrapper">
<div ng-controller="NameInput">
<label>Name:</label>
<input id="name-input" type="text" ng-model="yourName" placeholder="Enter a name here">
<hr>
<h1>Hello {{yourName}}</h1>
</div>
</div>
</body>
Here you go...
I think this might help you
var app = angular.module("todoApp", []);
app.filter("NameInput", function() {
return function(input) {
if (input != null) {
input = input.toLowerCase();
return input.substring(0, 1).toUpperCase() + input.substring(1);
}
}
})
.controller('NameInput', function($scope) {
$scope.yourName = "";
});
<body ng-app="todoApp" ng-cloak>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.js"></script>
<div id="wrapper">
<div ng-controller="NameInput">
<label>Name:</label>
<input id="name-input" type="text" ng-model="yourName" placeholder="Enter a name here">
<hr>
<h1>Hello {{yourName | NameInput}}</h1>
</div>

You are on the right track, just return the array inside the displayData()
this.displayData=function(){
return noteArray;
}
DEMO
var app=angular.module('noteApp',[]);
app.service('dataService',function(){
var noteArray=[];
this.saveData=function(data){
console.log(noteArray);
return noteArray.push(data);
}
this.displayData=function(){
return noteArray;
}
});
app.controller('noteCtrl',function($scope,dataService) {
$scope.noteArray=[];
$scope.add=function(){
dataService.saveData($scope.note);
$scope.noteArray = dataService.displayData();
}
});

Well I think that you need some like that:
'use strict';
app.factory('$shared',[function(){
function foo() {
var self = this;
self.list = [];
}
return new foo();
}]);
app.controller('mainCtrl', ['$scope', '$shared', function($scope, $shared){
$scope.shared = $shared;
//... many things here
$scope.onClick = function() {
// be sure that, I use "shared" from $scope, no directly like "$shared"
$scope.shared.list.push("val1");
console.log("my shared array:", $scope.shared.list);
}
}]);
app.controller('secondCtrl', ['$scope', '$shared', function($scope, $shared){
$scope.shared = $shared;
//... many things here
$scope.onKeyPress = function() {
// be sure that, I use "shared" from $scope, no directly like "$shared"
$scope.shared.list.push("val2");
console.log("my shared array:", $scope.shared.list);
}
}]);
Here is my angular view,
<label class="control-label">skipColumns:</label>
<br />
<fieldset ng-repeat="skipColumn in config.skipColumns track by $index">
<input type="text" class="form-control" ng-model="skipColumn[0]" /><br />
</fieldset>
<button class="btn btn-default" ng-click="addNewSkipColumn(skipColumn)">Add SkipColumn</button>
<br />
which adds new textfield every time i click addSkipColumn button.
here is my js code:
$scope.config.skipColumns = [];
$scope.addNewSkipColumn = function (skipColumn) {
if($scope.config.skipColumns==null){
$scope.config.skipColumns=[];
}
$scope.config.skipColumns.push([]);
}
so the problem is when I display or see the structure of $scope.config.skipColumns, It gives the following output:
{
skipColumns:[["content of textfield1"],["content of textfield1"]..]
}
But what I need is,`
{
skipColumns:["content of textfield1","content of textfield1",..]
}
please help me.("content of textfield" resfers to form data)
What you need here is to change what you are pushing in config.skipColumns array. Like this:
$scope.addNewSkipColumn = function(skipColumn) {
$scope.config.skipColumns.push("");
}
And, ng-repeat would be like:
<fieldset ng-repeat="skipColumn in config.skipColumns track by $index">
<input type="text" ng-model="config.skipColumns[$index]" />
</fieldset>
(why did I not use skipColumn directly in the ng-model?)
Here's working example:
angular.module("myApp", [])
.controller("ctrl", function($scope) {
$scope.config = {};
$scope.config.skipColumns = [];
$scope.addNewSkipColumn = function(skipColumn) {
$scope.config.skipColumns.push("");
}
})

See this... Just push value instead of array.
var app = angular.module('angularjs', []);
app.controller('MainCtrl', function($scope) {
$scope.choices = ['choice1'];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push('choice'+newItemNo);
};
$scope.removeChoice = function() {
var lastItem = $scope.choices.length-1;
$scope.choices.splice(lastItem);
};

I'm kinda new in AngularJS and my issue is:
I have a loop like this:
<body ng-app="ngToggle">
<div ng-controller="AppCtrl">
<input type="checkbox" ng-repeat="btn in btns" class="here" value="{{btn.value}}">
<input type="text" class="uncheck" disabled>
</div>
</body>
One of those checkboxes has a value of "OTHER", and what I need to do is: when the checkbox with the "OTHER" value is checked it remove the disabled attribute from the <input type="text" class="uncheck" disabled>
This is my controller:
angular.module('ngToggle', [])
.controller('AppCtrl',['$scope', function($scope){
$scope.btns = [
{value:'one'},
{value:'two'},
{value:'other'}
];
}]);
Hope someone can help me,
Thanks.
Use ng-change directive and test value of other checkbox in forEach-loop
angular.module('ngToggle', [])
.controller('AppCtrl', ['$scope',
function($scope) {
$scope.disabled = true;
$scope.btns = [{
value: 'one'
}, {
value: 'two'
}, {
value: 'other'
}];
$scope.onChange = function() {
$scope.btns.forEach(function(btn) {
if (btn.value === 'other' && btn.status === true) {
$scope.disabled = false;
} else {
$scope.disabled = true;
}
});
}
}
]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="ngToggle">
<div ng-controller="AppCtrl">
<input type="checkbox" ng-repeat="btn in btns" class="here" ng-model='btn.status' ng-change='onChange()'>
<input type="text" class="uncheck" ng-disabled='disabled'>
</div>
</body>
try like this.
angular.module('ngToggle', [])
.controller('AppCtrl',['$scope', function($scope){
$scope.btns = [
{value:'one',name:"one"},
{value:'two',name:'two'},
{value:'other',name:'other'}
];
$scope.disable=true;
$scope.check = function(value){
if(value == "'other'")
$scope.disable = false;
else
$scope.disable=true;
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="ngToggle">
<div ng-controller="AppCtrl">
<div ng-repeat="btn in btns">
<input type="checkbox" ng-model="btn.value" ng-true-value="'{{btn.value}}'" ng-change="check(btn.value)" >{{btn.name}}
</div>
<input type="text" class="uncheck" ng-disabled='disable'>
</div>

Make use of ng-models. Please avoild using "values attribute" as well in AngularJS. The alternative for values is "ng-init". Well anyway, here is a working code:

</head>
<body ng-app="ngToggle">
<div ng-controller="AppCtrl">
<p ng-repeat="btn in btns">
<input type="checkbox" ng-model="btn.bool" value="ss" class="here" > {{ btn.value }}
</p>
<input type="text" ng-model="textModel" class="uncheck" ng-disabled="other.bool">
<p>{{ other.bool }} -- {{textModel }}</p>
</div>
<script type="text/javascript">
angular.module('ngToggle', [])
.controller('AppCtrl',['$scope', function($scope){
$scope.btns = [
{value:'one', bool:false},
{value:'two', bool:true},
{value:'other', bool:true}
];
$scope.otherBool = $scope.btns[2]['bool'];
$scope.btns.map(function(obj){
//alert(JSON.stringify(obj))
if((obj.value) == 'other'){
$scope.other = obj;
}
});
}]);

I'm new at Angular.js, and I have a problem with a textarea element. When I write something and I click the add this step button , the text that I put in my text area is still there, but I don't know why.
HTML code:
<div class="form-group">
<label for="stepAdd">Step</label>
<textarea class="form-control" rows="3"
id="stepAdd" placeholder="Describe the solution to solve the problem step by step"
ng-model="textStep" >
</textarea>
Add this step
Angular code :
$scope.addStep = function(text) {
if(text === undefined) return;
var textFormat = text.trim();
$scope.textStep = '';
$scope.newDoc.steps.push({
text: textFormat,
editing : false,
images : []
});
}
var app = angular.module('app', []);
app.controller('firstCtrl', function($scope) {
//make sure that you define $scope.newDoc
$scope.newDoc = {
steps: []
}
$scope.addStep = function(text) {
if (text === undefined) return;
var textFormat = text.trim();
$scope.textStep = '';
$scope.newDoc.steps.push({
text: textFormat,
editing: false,
images: []
});
};

How can we add a textbox element to a form dynamically using AngularJs. For example in this case, I have a text and textbox which I want to add one other of this pair by clicking on a button using AngularJs.
<div ng-app>
<div ng-controller="ClickToEditCtrl">
<div ng-hide="editorEnabled" ng-click="editorEnabled=true">
{{title}}
</div>
<div ng-show="editorEnabled">
<input ng-model="title">
<button href="#" ng-click="editorEnabled=false">Done editing</button>
</div>
</div>
</div>
<div>
<input type="text" placeholder="Enter answer">
</div>
I implemented it myself. You could dynamically add an element by using ng-repeat in a
<li ng-repeat="elemnt in questionelemnt">
Here it is the Demo: fiddle
js file
$scope.choices = [{id: 'choice1'}, {id: 'choice2'}, {id: 'choice3'}];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push({'id':'choice' +newItemNo});
};
$scope.showAddChoice = function(choice) {
return choice.id === $scope.choices[$scope.choices.length-1].id;
};
html
<div class="form-group" data-ng-repeat="choice in choices">
<label for="choice" ng-show="showChoiceLabel(choice)">Choices</label>
<button ng-show="showAddChoice(choice)" ng-click="addNewChoice()">Add another choice</button>
<input type="text" ng-model="choice.name" name="" placeholder="Enter a restaurant name">
</div>
