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>
</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:
<!DOCTYPE html>
<html >
<head>
<link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

<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;
}
});
}]);
</script>
</body>

I have below code where I am displaying buttons based on array values. I want to select button based on a condition which checks if it matches with another array values. I have added an ng-class to check i in array1 loop matches listApi but couldn't come up with correct logic and get it tow work. Need help please
<label ng-repeat="i inn array1 track by $index">
<label class="btn-primary" ng-click="array1Selection()">
<span ng-class="{'btn-primary': i.name === listApi[0].name}"></span>
{{i.name}}
</label>
</div>
</label>
Your span tag is empty and I think you should put {{i.name}} inside that. also you should not add class 'btn ...' to your label. Hope this code helps you.
var app = angular.module("app", []);
app.controller("MainCtrl", function($scope) {
$scope.array1 = [{
id: 1,
name: "abc"
}, {
id: 1,
name: "xyz"
}];
$scope.listApi = [{
id: 2,
name: "xyz"
}];
$scope.existInList = function(itm) {
let x = $scope.listApi.findIndex(it => {
return it.name == itm.name
});
return x == -1 ? false : true;
}
});
.exists {

.noexists {

I'm not 100% sure JS' find will work inline in Angular but is so...
<label ng-repeat="i inn array1 track by $index">
<div data-toggle="buttons">
<label class="btn btn-w-m btn-primary" ng-click="array1Selection()">
<div class="itemcontent">
<input type="checkbox" name="array1Select" />
<span nng-class="btn btn-w-m btn-primary: listApi.find(a => a.name === i.name)"></span>
{{i.name}}
</div>
</label>
</div>
</label>
A simple modification
var app = angular.module("app", []);
app.controller("MainCtrl", function($scope) {
$scope.array1 = [{ id: 1, name: "abc" }, { id: 1, name: "xyz"
}];
$scope.listApi = [{ id: 2, name: "xyz" }];
$scope.foundInApiList = function(name) {
for(var i = 0; i < $scope.listApi.length; i++)
if($scope.listApi[i].name == name)
return true;
return false;
}

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 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>

Since I am using Semantic UI for checkboxes, the <input> tag is wrapped with a <div class="ui checkbox"> and what happens is when the box is checked, it just adds the class checked.
<div class="field" ng-repeat="animal in animals">
<div class="ui checkbox">
<input class="hidden" tabindex="0" type="checkbox" value="{{animal.id}}" ng-model="animal.selected">
<label>{{animal.name}}</label>
</div>
</div>
How do I get the id or value of the selected checkboxes using AngularJS? Thank you.
You can have a function in your controller
$scope.getAnimal= function(){
angular.forEach($scope.animals, function(animal){
if (animal.selected) do smth here...
})
}
You can use Array.prototype.filter() method to get only the selected objects.
Here's a demonstration:
angular.module('app', [])
.controller('mainCtrl', function($scope) {
$scope.animals = [];
for (var i = 0; i <= 5; i++) {
$scope.animals.push({
"id": Math.floor(Math.random() * 310),
"name": "Name " + Math.floor(Math.random() * 420),
"selected": i % 2 === 0 ? true : false
});
}
$scope.selected = [];
$scope.show = function() {
$scope.selected = $scope.animals.filter(function(value) {
return value.selected;
});
}
});

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">
