Hi Friends here i have done the code for change text of button, like if i press the button the text of the button will change. But i need the text of the button to be change one more time,
eg: initially "Button1" -->(click)-->"Button2" -->(click)-->"Button3".
I need button3 also.
please reffer:http://jsfiddle.net/Ljrpd/17/
var app = angular.module('my-app', [], function () {
})
app.controller('AppController', function ($scope) {
$scope.toggle = true;
$scope.$watch('toggle', function(){
$scope.toggleText = $scope.toggle ? 'Button1' : 'Button2';
})
})
Some one help me out in this issue.
Thanks
You don't need toggle variable, you can store selected index as suggested by Peter. I would also add check for last selection:
app.controller('AppController', function ($scope) {
$scope.buttonIndex = 0;
$scope.buttonNames = ['Button 1', 'Button 2', 'Button 3', 'Last Button']
$scope.changeText = function() {
if ($scope.buttonIndex === $scope.buttonNames.length - 1) {
$scope.buttonIndex = 0;
} else {
$scope.buttonIndex += 1;
}
};
});
JS Fiddle
Try my modification:
http://jsfiddle.net/Ljrpd/18/
<button ng-click="toggle = !toggle">{{buttonNames[buttonIndex]}}</button>
var app = angular.module('my-app', [], function () {
})
app.controller('AppController', function ($scope) {
$scope.toggle = true;
$scope.buttonIndex = 0;
$scope.buttonNames = ['first', 'second', 'third']
$scope.$watch('toggle', function(){
$scope.buttonIndex += 1;
})
})
And here's a version without a watch:
http://jsfiddle.net/russf6s9/1/
<button ng-click="incrementButton()">{{buttonNames[buttonIndex]}}</button>
var app = angular.module('my-app', [], function () {
})
app.controller('AppController', function ($scope) {
$scope.buttonIndex = 0;
$scope.incrementButton = function() {
$scope.buttonIndex += 1;
}
$scope.buttonNames = ['first', 'second', 'third']
})
Use a directive:
app.directive('changeText', function(){
return {
restrict: "A",
scope: {
changeText: "="
},
link: function(scope, element, attr) {
scope.index = 0;
element.html(scope.changeText[0]);
element.on('click', function(){
scope.index = (scope.index + 1) % scope.changeText.length;
element.html(scope.changeText[scope.index]);
})
}
};
})
Then in your html:
<body ng-controller="MainCtrl as ctrl">
<button change-text="ctrl.textValues"></button>
</body>
Plnkr
Script:
.controller('myctrl', function ($scope) {
$scope.btntext='button_1';
$scope.changetext = function () {
$scope.btntext = ($scope.btntext=='button_1')?'button_2':($scope.btntext=='button_2')?'button_3':'button_1';
}
});
Markup:
<input type="button" ng-click="changetext()" ng-value="btntext"/>

No matter what I select, this function only returns the first item of the list. As requested, I have included the complete JS code. I have looked through this code four hours and everything seems right to me. This is my first contact with Angular and any help will be greatly appreciated!
Thank you!

The buy-ticket directive makes an http call, on the response i want to be able to call the onBuyTicket method of the <export> directive.
I'm trying to understand the best way to do that.
Thanks everyone
This sample show to you how can call an function from your directive
In this sample you can see we just insert data in our directive, and then we handle the data and other action in the directive.
var app = angular.module("app", []);
app.controller("ctrl", function ($scope) {
$scope.dataFromYourController = [
{ name: "Concert Jennifer", value: 200 },
{ name: "007", value: 100 }
];
})
.directive("export", function () {
var template = "<div>" +
"<ul>" +
"<li ng-repeat=\"array in arrays\">" +
"<button ng-click=\"onBuyTicket()\">buy Ticket {{array.name}}</button><hr>" +
"</li>" +
"</ul>" +
"</div>";
return {
restrict: "E",
template: template,
scope: {
data: "="
},
link: function (scope, elem, attrs, ngModel) {
scope.arrays = scope.data;
scope.onBuyTicket = function () {
alert("calling function from directive");
}
}
};
})
<!doctype html>
<html ng-app="app" ng-controller="ctrl">
<head>
</head>
<body>
<h1>call action from your directive</h1>
<export data="dataFromYourController"></export>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</body>
</html>
#eesdil
var directive = {
restrict: 'AE',
transclude: true,
controller : function($scope) {
$scope.onBuyTicket = function() {
alert('hey');
}
}
}
Ho can I call that from the buy-ticket directive ?
Use the $parent
<button buy-ticket="{{data}}" buy-callback="$parent.onBuyTicket()">buy</button>
So the expor directive something like:
var directive = {
restrict: 'AE',
template: '<ng-tansclude></ng-transclude>',
transclude: true,
controller : function($scope) {
$scope.onBuyTicket = function() {
alert('hey');
}
}
}
UPDATED:
see the plunker:
https://plnkr.co/edit/fmyJ4oPLvTiI0TzO7h1b?p=preview
It really depends what you can call and what you cannot based on the scopes... here if you would remove the scope from the export directive would work without the $parent also as export would share the same scope as the parent (main view)
The best way to communicate events from a child directive to a parent directive (or controller) is to use the $emit method of the scope.
What you want to do is take an ng-click event, get additional information with an $http call, and $emit an event with the additional information to be used by your parent directive (or controller).
HTML
<button buy-ticket="data" ng-click="onBuyTicket()">buy</button>
The directive:
angular.module("myApp").directive("buyTicket", function($http) {
function linkFn(scope,elem,attrs) {
scope.onBuyTicket = function() {
var buyData = scope.$eval(attrs.buyTicket);
var url = someFunction(buyData);
$http.get(url).then (function (response) {
var httpData = response.data;
scope.$emit("buyTicket.click", buyData, httpData);
});
};
};
return {
restrict: "AE",
link: linkFn
};
});
In the parent controller:
$scope.$on("buyTicket.click", function (buyData, httpData) {
console.log(buyData);
console.log(httpData);
});
Notice that I used the $eval method to get the data from the variable named by the buy-ticket attribute.
When choosing a name for the event, I recommend including the name of the directive in the event's name. It makes it clear the source of the event and is unlikely to be duplicated elsewhere.
I am having an example of what i want to achieve given below in plunker.As 10 changes on right click,i want an image there that should convert to some another image on right click.Please help me out with this.
http://jsfiddle.net/bcaudan/vTZZ5/
app.directive('ngRightClick', function($parse) {
return function(scope, element, attrs) {
var fn = $parse(attrs.ngRightClick);
element.bind('contextmenu', function(event) {
scope.$apply(function() {
event.preventDefault();
fn(scope, {$event:event});
});
});
};
});
made this fiddle for you: JsFiddle
Are you looking for something like this??
JS should be like this:
var app = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.img1 = "http://4.bp.blogspot.com/-JOqxgp-ZWe0/U3BtyEQlEiI/AAAAAAAAOfg/Doq6Q2MwIKA/s1600/google-logo-874x288.png";
$scope.img2 = "http://www.socialtalent.co/wp-content/uploads/blog-content/so-logo.png";
$scope.selected = $scope.img1;
$scope.increment = function() {
$scope.selected = $scope.img1;
};
$scope.decrement = function() {
$scope.selected = $scope.img2;
};
};
app.directive('ngRightClick', function($parse) {
return function(scope, element, attrs) {
var fn = $parse(attrs.ngRightClick);
element.bind('contextmenu', function(event) {
scope.$apply(function() {
event.preventDefault();
fn(scope, {$event:event});
});
});
};
});
and HTML should be:
<div ng-app="myApp" ng-controller="MyCtrl">
<span class="action"
ng-click="increment()"
ng-right-click="decrement()"><img ng-src="{{selected}}"></span>
</div>
Please see demo below
var app = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.images = [
'http://upload.wikimedia.org/wikipedia/commons/a/a7/Tiffanie_at_cat_show.jpg',
'http://www.thetimes.co.uk/tto/multimedia/archive/00342/114240651_cat_342943c.jpg'
];
$scope.imageSrc = 1;
$scope.toggleImage = function() {
$scope.imageSrc == 1 ? $scope.imageSrc = 0 : $scope.imageSrc = 1;
};
};
app.directive('ngRightClick', function($parse) {
return function(scope, element, attrs) {
var fn = $parse(attrs.ngRightClick);
element.bind('contextmenu', function(event) {
scope.$apply(function() {
event.preventDefault();
fn(scope, {
$event: event
});
});
});
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<image ng-src="{{images[imageSrc]}}" class="action" ng-right-click="toggleImage()" width="150px" />

Hope this is clear enough for someone to help me. If not let me know and I can try to clarify.
Using ui-bootstrap I have a really simple custom directive that lists alerts at the top of the page. On normal pages it works like a champ. When I use my directive inside a $modal popup I get "undefined is not a function" at ngRepeatAction.
The directive I have behind the modal on the main page still works. I can see it behind the modal. It's just the one in the modal popup that breaks. What am I doing wrong?
Modal open code:
$modal.open({
templateUrl: 'partials/main/servers/serverAuths/edit.html',
controller: function($scope, $modalInstance) {
$scope.auth = angular.copy(auth);
$scope.auth.password = null;
$scope.saveAuth = function() {
Auths.editAuth($scope.auth).then(
function(resp) {
if (resp.rc===0) {
Alerts.addAlert('success', 'Auth `'+$scope.auth.name+'` saved.');
_.extend(auth, $scope.auth);
$modalInstance.close();
} else {
Alerts.addAlert('danger', 'Auth `'+$scope.auth.name+'` could not be saved. ' + resp.message, 'serverAuths');
}
}
);
};
$scope.resetAuth = function() {
$modalInstance.close();
};
}
}).result.then(
function() {
Auths.getAuthList().then(
function(resp) {
$scope.auths = resp;
}
);
}
);
Directive template:
<div class="alert-wrapper alert-{{ alert.type }}"
ng-repeat="alert in alerts"
ng-class="{ 'relative':relative }">
<div class="container">
<div alert type="alert.type" close="closeAlert($index)">{{alert.msg}}</div>
</div>
</div>
Directive code:
angular.module('app')
.directive('appAlerts', function() {
return {
restrict: 'A',
replace: true,
scope: {
watchForm: '=',
relative: '#'
},
templateUrl: 'partials/directives/appAlerts.html',
controller: function($scope, Alerts) {
$scope.closeAlert = function(idx) { Alerts.closeAlert(idx); };
$scope.alerts = Alerts.getAlerts();
}
};
});
Alerts Factory:
angular.module('app').factory('Alerts', function($timeout) {
var alerts = [];
function timeoutAlert(a) {
$timeout(function() {
a.splice(0, 1);
}, 2500);
}
var addAlert = function(type, msg) {
alerts.push({type:type, msg:msg});
timeoutAlert(alerts);
};
var closeAlert = function(index) {
alerts.splice(index, 1);
