I'm new in AngularJS. Please have look to this:
Now when user clicks on "All" link, all the 11 check boxes should be checked and when user clicks on "None" link, all the 11 check boxes should be unchecked.
Plus when user check the All others check box, all the bottom 9 check boxes should be checked and when user uncheck the All others check box, all the bottom 9 check boxes should be unchecked.
I'm able to achieve one of the task at a time, but not simultaneously.
So, can anybody please help me to achieve both the tasks simultaneously?
Any help would be appreciated.
You can use
HTML
<body ng-controller="MainCtrl">
<button ng-click="selectAll()">Select All</button>
<button ng-click="clearAll()">Clear All</button>
<input type="checkbox" ng-model="select" ng-click="checkAll()" />
<br />
<p>Checkboxes</p>
<input type="checkbox" ng-repeat="c in checkbox" ng-model="checkbox[$index].selected">
</body>
Angular
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.checkbox = [
{
selected: false
},
{
selected: false
},
{
selected: false
}
];
// Check/uncheck all boxes
$scope.selectAll = function () {
$scope.select = true;
angular.forEach($scope.checkbox, function (obj) {
obj.selected = true;
});
};
$scope.clearAll = function () {
$scope.select = false;
angular.forEach($scope.checkbox, function (obj) {
obj.selected = false;
});
};
$scope.checkAll = function () {
angular.forEach($scope.checkbox, function (obj) {
obj.selected = $scope.select;
});
};
});
Refer fiddle
Html
<button ng-click="selectAll()"> all</button>
<div ng-repeat="item in items">
<input type="checkbox" ng-model="selected[item.id]">
</div>
JQuery
$scope.selected = {};
$scope.selectAll= function(){
for (var i = 0; i < $scope.items.length; i++) {
var item = $scope.items[i];
$scope.selected[item.id] = true;
}
};
you can use ng-Checked
Its makes you easier
refer ng-Checked
<md-checkbox ng-click="checked = !checked; check = {}"></md-checkbox>
<div ng-repeat="item in [1,2,3,4,5]">
<md-checkbox ng-checked="checked || check[item]" ng-click="check[item] = !check[item]" ng-model="sel[item]"></md-checkbox>
</div>

In my HTML form there are 5 check boxes. How can I check which check boxes are checked or not at the time of the form submission?
I am using this little piece of code. Feel free to take it.
In your controller:
$scope.sentinel = [];
$scope.toggleSelection = function(value) {
// Bit trick, equivalent to "contains"
if (~$scope.sentinel.indexOf(value)) {
var idx = $scope.sentinel.indexOf(value);
$scope.sentinel.splice(idx, 1);
return;
}
$scope.sentinel.push(value);
};
Then in your HTML:
<span ng-repeat="key in $scope.yourarray">
<md-checkbox style="margin-left:30px;" aria-label="Select item"
ng-click="toggleSelection(key)"><span>{{ key }}</span></md-checkbox>
<br/>
</span>
This allows you to have an array of any size and using the sentinel array to register already checked values. If you check again a box, the toogleSelection will prevent you from adding again a value.
You can use the Checklist-model of Angular.js. It is very useful:
var app = angular.module("app", ["checklist-model"]);
app.controller('Ctrl1', function($scope) {
$scope.roles = [
'guest',
'user',
'customer',
'admin'
];
$scope.user = {
roles: ['user']
};
$scope.checkAll = function() {
$scope.user.roles = angular.copy($scope.roles);
};
$scope.uncheckAll = function() {
$scope.user.roles = [];
};
$scope.checkFirst = function() {
$scope.user.roles.splice(0, $scope.user.roles.length);
$scope.user.roles.push('guest');
};
$scope.showCheckedOnes = function() {
var checkedBoxes = "";
for (var i = 0; i < $scope.user.roles.length; i++) {
checkedBoxes += $scope.user.roles[i] + " ";
}
alert(checkedBoxes);
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://vitalets.github.io/checklist-model/checklist-model.js"></script>
<div ng-app="app">
<div ng-controller="Ctrl1">
<label ng-repeat="role in roles">
<input type="checkbox" checklist-model="user.roles" checklist-value="role"> {{role}}
</label>
<div>
<div>
<button ng-click="checkAll()" style="margin-right: 10px">Check all</button>
<button ng-click="uncheckAll()" style="margin-right: 10px">Uncheck all</button>
<button ng-click="checkFirst()" style="margin-right: 10px">Check first</button>
<button ng-click="showCheckedOnes()" style="margin-right: 10px">Show checked ones</button>
You can define the array value and map to html.
$scope.checkbox = [];
HTML
<input ng-model="checkbox[0] type="checkbox" />
<input ng-model="checkbox[1] type="checkbox" />
<input ng-model="checkbox[2] type="checkbox" />
<input ng-model="checkbox[4] type="checkbox" />
Or you can define checkbox as object and change checkbox[index] to checkbox[name].
I have a question about the AngularJS editable framework. When using an editable, two buttons appear: the save button and the cancel button. However, I want a third button (with a minus symbol) to delete the text in the editable. How can I add a third delete button?
Here is a fiddle of one of my previous questions:
Example with only two buttons
{{ user.name || 'empty' }}
Don't think they have support for this right now.
I've done it myself.
var app = angular.module("app", ["xeditable"]);
app.run(function (editableOptions) {
editableOptions.theme = 'bs3';
});
app.controller('Ctrl', function ($scope) {
$scope.user = {
name: 'awesome user'
};
$scope.showClear = function () {
$scope.show = true;
}
$scope.empty = function () {
$scope.user.name = "";
$scope.show = false;
}
});
<h4>Angular-xeditable Text (Bootstrap 3)</h4>
<div ng-app="app" ng-controller="Ctrl">
<span href="#" editable-text="user.name" ng-click="showClear()">{{ user.name || 'empty' }}</span>
<button class="btn btn-default" ng-click="empty()" ng-show="show">
-
</button>
</div>
Hope this will help :).
I am using Angularfire and I'd like to remove the items by checkbox.
And there is a button that can do the "checkAll" and another do the "uncheckAll"
HTML
<div ng-app="app" ng-controller="Ctrl">
<li ng-repeat="item in newslist">
<input type="checkbox"> {{item.newsTitle}}
</li>
<br>
<button ng-click="checkAll()">check all</button>
<button ng-click="uncheckAll()">uncheck all</button>
<button ng-click="newslist.$remove(item)">Remove</button>
</div>
JS
var app = angular.module("app", ["firebase"]);
app.value('newsURL', 'https://XXX.firebaseio.com/XXX/');
app.factory('newsFactory', function($firebase, newsURL) {
return $firebase(new Firebase(newsURL)).$asArray();
});
app.controller('Ctrl', function($scope, $firebase, newsFactory) {
$scope.newslist = newsFactory;
$scope.checkAll = function() {
};
$scope.uncheckAll = function() {
};
});
plunker here
I don't know how to remove the items by checkbox or how to make the "checkAll" button work.
I will be appreciate if someone could tell me your answer.
Here is function you would need to check/uncheck and for removing items:
$scope.checkAll = function() {
$scope.newslist.forEach(function(el) {
el.checked = true;
$scope.newslist.$save(el);
});
};
$scope.uncheckAll = function() {
$scope.newslist.forEach(function(el) {
el.checked = false;
$scope.newslist.$save(el);
});
}
$scope.remove = function() {
$scope.newslist.forEach(function(item) {
if (item.checked) {
$scope.newslist.$remove(item);
}
});
};
Demo: http://plnkr.co/edit/GsGVsGGjNwW4i1kTOuko?p=preview
I added checked property for ngModel directive.
HTML becomes:
<li ng-repeat="item in newslist">
<input type="checkbox" ng-model="item.checked">{{item.newsTitle}}
</li>
<button ng-click="checkAll()">check all</button>
<button ng-click="uncheckAll()">uncheck all</button>
<button ng-click="remove()">Remove</button>
I am trying to include a check all for my todo list, but once I hit toggleAll() it gets unchecked right away, plus it unchecks whichever one is already checked.
I really couldn't figure out why this behavior, perhaps some other things in the page are interfearing. A simple version of what I have included here is in this jsfiddle http://jsfiddle.net/TKVH6/487/ and it is working.
<section id="main">
<input id="toggle-all" type="checkbox" ng-model="checkAll" ng-click="toggleAll()">
<label for="toggle-all">Mark all as complete</label>
<ul id="todo-list">
<li ng-repeat="todo in todos" ng-class="{'completed': todo.isCompleted=='true'}" class="editing">
<div class="view" >
<input class="toggle" type="checkbox" ng-click="complete(todo)" ng-model="todo.isCompleted" ng-checked="todo.isCompleted" ng-true-value="'true'" ng-false-value="'false'">
<label ng-hide="isEditing" ng-dblclick="isEditing = !isEditing">{{todo.title}}</label>
<button class="destroy" ng-click="remove(todo)"></button>
</div>
<input class="edit" ng-show="isEditing" ng-model="todo.title" ng-blur="isEditing = !isEditing;edit(todo);">
</li>
</ul>
</section>
Controller
$scope.toggleAll = function () {
if ($scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.todos, function (todo) {
todo.isCompleted = $scope.selectedAll;
});
};
EDIT 1
$scope.toggleAll = function() {
for(i in $scope.todos) {
$scope.todos[i].isCompleted = $scope.checkAll;
}
};
Any help is appreciated.
SOLVED! Treating the boolean as string solved it. That is because the server saves the boolean values as strings.
$scope.toggleAll = function() {
for(i in $scope.todos) {
$scope.todos[i].isCompleted = "" + $scope.checkAll;
}
};
At this point ng-checked="{{todo.isCompleted}} needs to be back since it is not a boolean.
I am trying to change the placeholder in the textbox by changing the checkbox using angular. I tried fiddle http://jsfiddle.net/d9uc1dxc/5/.
I have the following code:
**SCRIPT**
function TController($scope) {
$scope.placeholder="%";
$scope.formData = {};
$scope.radioChecked = function ()
{
$scope.placeholder="%";
$scope.apply();
}
$scope.radiounChecked = function ()
{
$scope.placeholder="Count";
$scope.apply();
}
}
What I am trying to achieve is (1) if I change to "%" then the textbox placeholder and (2) if I change to "Count" then the textbox placeholder should change to "Count".
Someone please help me in this issue.
please try to use this code
this is the script file
var app = angular.module("TestApp", []);
function TController($scope) {
$scope.placeholder="%";
$scope.formData = {};
$scope.radioChecked = function ()
{
if($scope.placeholder == "%"){
$scope.placeholder = "Count";
}else{
$scope.placeholder = "%";
}
}
}
and here is the html file
<body ng-app="TestApp" ng-controller="TController">
<div class="flw vreq2">
<label>Voting require2</label>
<div class="oneline">
<div class="onoffswitches">
<input type="checkbox" name="onoffswitch" ng-click="radioChecked()" class="onoffswitch-checkbox" id="myonoffswitch7"/>
<label class="onoffswitch-label" for="myonoffswitch7">
<span class="onoffswitch-inner"></span>
<span class="onoffswitch-switch"></span>
</label>
</div>
</div>
</div>
<div class="per1">
<input type="text" placeholder="{{placeholder}}" ng-model="formData.textInput" />
</div>
</body>
hope you find this useful
you dont need the two functions for checked & unchecked
use ng-change in check box as and add a model to checkbox // model name = onoffswitch
<input type="checkbox" ng-model="onoffswitch" ng-change="radioChecked()" ...
when checkbox checked, onoffswitch model value will be true otherwise false
when changing the checkbox radioChecked() function will invoke
$scope.radioChecked = function ()
{
if($scope.onoffswitch) {
$scope.placeholder="%";
} else {
$scope.placeholder="Count";
}
}
