change the text of the button on click using angular JS - javascript

How I can change the text of the button on click of the button.
Here it is what I have tried.
HTML:
<button ng-click="toggle = !toggle">Toggle!</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>
JS:
function MainController($scope) {
$scope.toggle = true;
}

Or, keep all the content in your HTML, rather than defining the button text in the controller, if you prefer:
<button ng-click="toggle = !toggle">
<span ng-show="toggle">Toggle to Off</span>
<span ng-hide="toggle">Toggle to On</span>
</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>

I think, using a watch of toggle should do it
<button ng-click="toggle = !toggle">{{toggleText}}</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>
then
app.controller('AppController', function ($scope) {
$scope.toggle = true;
$scope.$watch('toggle', function(){
$scope.toggleText = $scope.toggle ? 'Toggle!' : 'some text';
})
})
Demo: Fiddle

I would use neither watch nor ng-show because of their performance. That is simple as this:
app.controller('AppController', function ($scope) {
$scope.toggle = true;
})
<button ng-click="toggle = !toggle">{{toggle && 'Toggle!' || 'some text'}}</button>

Here's my solution, supporting translation:
HTML:
<span class="togglebutton">
<label>
<input type="checkbox" checked="{{myApp.enabled}}"
ng-model="myApp.enabled" ng-click="toggleEnabled()">
<span translate="{{myApp.enableCaption}}">Is Enabled?</span>
</label>
</span>
JS - Controller:
$scope.toggleEnabled = function() {
$scope.myApp.enableCaption = $scope.myApp.enabled ? 'global.enabled' : 'global.disabled';
};
where global.enabled and global.disabled refer to i18n JSON translations. You also need to initialize enableCaption in JS, in place where you create an empty object.

apply css based on condition angularjs

I'm alternating between two windows in angularjs using ng-click and ng-show :
<div ng-init="showTab2 = false">
<a ng-click="showTab2 = true; showTab1 = false ">#Tab1 </a>
</div>
<div ng-init="showTab2 = true">
<a ng-click="showTab1 = true; showTab2 = false">#Tab2</a>
</div>
then with ng-show they appear
Could you please tell me how I can change the color of the tab selected ?
Thank you
I'm not sure how your ng-show fits here but use ng-class to toggle css:
<a ng-class = "{'some-class': showTab1}"
ng-click="showTab1 = true; showTab2 = false">#Tab1</a>
Please check working example here: Example
JS
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.showTab = 1; //If you want to select default tab
});
HTML
<div>
<a ng-click="showTab = 1" ng-class="{'active': showTab == 1}">#Tab1 </a>
</div>
<div>
<a ng-click="showTab = 2" ng-class="{'active': showTab == 2}">#Tab2</a>
</div>
<div ng-switch="showTab">
<span ng-switch-when="1">Tab1</span>
<span ng-switch-when="2">Tab2</span>
</div>
CSS
.active {
color: red;
}

Can't hide div in angularjs

When clicking module class it shows emptylabel. but i cant hide the module class.
<div id="b" class="tab-pane fade in active" >
<div class="secondrow">
<div ng-show="divshow">
<label class="emptylabel"> <input type="button" value="back" class="backbutton" ng-click="hidediv()"></label>
</div>
<div class="module">
<a href="#/b" class="{{module}}" ng-click="showdiv()">
<div class="col-sm-4"><label>Jawaharlal Nehru</label></div>
<div class="col-sm-1"><label>111111</label></div>
<div class="col-sm-2"><label>2222222</label></div>
<div class="col-sm-3"><label>3333333</label></div>
</a>
</div>
Controller:
app.controller('myController', ['$scope', function($scope) {
$scope.showdiv = function () {
$scope.divshow = true;
$scope.module = false;
}
// Hide Div
$scope.hidediv = function () {
$scope.divshow = false;
}
}]);
I'm not sure if I understand your question correctly. If you want to toggle between the emptylabel and module, the you can use ng-show for both of them, based on the divshow variable:
<div ng-show="divshow">
<label class="emptylabel">
<input type="button" value="back" class="backbutton" ng-click="hidediv()">
</label>
</div>
<div class="module" ng-show="!divshow">
<a href="#/b" class="{{module}}" ng-click="showdiv()">
...
</a>
</div>
controller:
app.controller('myController', ['$scope', function($scope) {
$scope.showdiv = function () {
$scope.divshow = true;
}
$scope.hidediv = function () {
$scope.divshow = false;
}
}]);
What does your ng-controller declaration in the HTML look like? For example mine usually look something like this, with the capture variable 'vm':
<div data-ng-controller="FooController as vm">
<div>
<span data-ng-click="vm.showDiv()"></span>
</div>
</div>
Inside your controller:
function FooController() {
var vm = this;
vm.showDiv = showDiv;
function showdiv() {
// Your code here
}
}

How do I access ng-show directive with ng-click? AngularJS

I just started learning so I'm creating a todo app.
I'm trying to show a div when I click on the edit button to edit my task.
this is my html
<div ng-controller='TasksCtrl'>
<div ng-repeat='(key, task) in tasksList' class='task-list'>
<div class='easy'>
<div class='div-list-style'></div>
<div id='task-{{key}}' style='cursor:pointer;z-index:5'
ng-click='editTask()' data-key='{{key}}' class='options
pull-right glyphicon glyphicon-pencil'>
</div>
<div class='task-desc' ng-bind='task.description'></div>
<div ng-hide='taskEdit = true'>FORM</div>
</div>
</div>
</div
This is my controller
todoApp.controller('TasksCtrl',['$scope', 'saveTaskService', function($scope, saveTaskService){
$scope.editTask= function(){
todoApp.directive('taskEdit', function(){
return function(scope, element){
//so I guess over here I need do ngHide = 'false' ? //
alert(element.attr('data-key'));
};
});
};
}]);
Here is a quick solution, you have a scope variable called taskShow that will tell ng-hide when to show it, then on ng-click you will trigger a function that will toggle that value:
<div ng-controller='TasksCtrl'>
<div ng-repeat='(key, task) in tasksList' class='task-list'>
<div class='easy'>
<div class='div-list-style'></div>
<div id='task-{{key}}' style='cursor:pointer;z-index:5'
ng-click='toggleHide(key)' data-key='{{key}}' class='options
pull-right glyphicon glyphicon-pencil'>
</div>
<div class='task-desc' ng-bind='task.description'></div>
<div ng-show='taskShow[key]'>FORM</div>
</div>
</div>
</div>
Controller:
todoApp.controller('TasksCtrl',['$scope', 'saveTaskService', function($scope, saveTaskService){
$scope.taskShow = {};
$scope.toggleHide = function (key) {
$scope.taskShow[key] = !$scope.taskShow[key];
};
}]);
Edit: switched ng-hide to ng-show so the divs are hidden by default and only shown when the other is clicked.

Change Text in a button using ng-click

I am trying to change the text in the button using angular I am pretty much done but I have a few questions.
First, my code below just changes the text when I click the first time, how can I change it again after the second click? That button is hiding a <DIV> so that is the reason for the change?
Angular:
angular.module('test',[])
.controller('MyCtrl',function ($scope) {
$scope.myText = 'Press to start';
$scope.start = function () {
$scope.myText = 'Starting...';
}
});
HTML:
<body ng-controller="MyCtrl">
<button ng-click="start()"> {{ myText }} </button>
</body>
The second part of my question is:
How can I apply that code in that code up in that HTML and Angular?
HTML:
<a ng-click="Menu()" class="btn btn-default" id="menu-client">hide the search</a>
Angular:
$scope.Menu = function(){
$("#wrapper").toggleClass("toggled");
};
Changing text:
JS
angular.module('test',[])
.controller('MyCtrl',function ($scope) {
$scope.myText = 'Press to start';
$scope.start = function (myText) {
$scope.myText = (myText === 'Starting...') ? 'Finish' : 'Starting...';
}
});
HTML
<body ng-controller="MyCtrl">
<button ng-click="start(myText)"> {{ myText }} </button>
</body>
Changing class:
JS
$scope.isToggled = false;
HTML
<a ng-click="isToggled = true" class="btn btn-default" ng-class="{toggled: isToggled}" id="menu-client">hide the search</a>
HTML
<a ng-click="Menu()" class="btn btn-default" id="menu-client">hide the search</a>
Angular
$scope.Menu = function(){
$scope.isHedden = true;
};
Now whichever element in the HTML that you want to hide/show, use ngHide directive for that:
<some-element ng-hide="isHidden">Some plain text or value goes here</some-element>
Look out https://docs.angularjs.org/api/ng/directive/ngHide for more details on this directive.

Why does my View not update in Angularjs on click, though I am able to get the content?

<div class="test" ng-controller="Ctrl">
<div ng-repeat="task in tasks">
<button ng-click="removeTask(task.id);">remove</button>
<div class="content">{{taskId}}</div>
</div>
<div>
var app = angular.module('app', []);
function Ctrl($scope) {
$scope.tasks = [{id:1,'name':'test1'}, {id:2,'name':'test2'}, {id:3,'name':'test3'}];
$scope.removeTask = function(taskId){
alert("Task Id is "+taskId);
};
}
The content I get in alert needs to be put in div, but the div won't get updated, what am I not doing correctly?
jsFiddle Demo
If you want id of task - task.id. taskId is just name for function parameter, it's undefined outside this function.
<div class="content">{{task.id}}</div>
But I suppose, best practice would be to pass whole object to click function:
$scope.removeTask = function(task){
alert("Task Id is " + task.id);
};
http://jsfiddle.net/PSz7t/3/
There different way's how you can achieve what are you looking for.
Here is mine. Since you need write an 'alert' for each removed item you need to save the status for each item so you can decide to show the alert or not
<div class="test" ng-controller="Ctrl">
<div ng-repeat="task in tasks">
<button ng-click="removeTask(task);">remove</button>
<div class="content"> <span ng-show="task.status=='deleted'">Task Id is {{task.id}} </span> </div>
</div>
<div>
http://jsfiddle.net/PSz7t/9/
var app = angular.module('app', []);
function Ctrl($scope) {
$scope.tasks = [{id:1,'name':'test1',status:'active'}, {id:2,'name':'test2',status:'active'}, {id:3,'name':'test3',status:'active'}];
$scope.removeTask = function(task){
task.status='deleted';
};
}
