I am trying to show Success message , once the data is updated in my application. Success function is working properly , but message is not getting generated. when I click on the save() button, small alert box will display, but message wont appear.
HTML : <div class="alert alert-success" ng-show="successmessage">{{cts.success_info}}</div>
Angular Js:
$scope.successmessage = function(){
$scope.cts = [];
$scope.cts.success_info = "Data Successfully got updated";
}
You defined successmessage as a function, but using it as a value.
If you need to display alert on success call of save function, use success function below. It creates an object with a message and isSuccess flag:
Html:
<div class="alert alert-success" ng-show="cts.isSuccess">{{ cts.message }}</div>
JS:
$scope.success = function() {
$scope.cts = {
isSuccess: true,
message: 'Data Successfully got updated'
};
}
Working demo
You can take advantage of *ngIf if want to display more then just simple string like below:
showMsg: boolean = false;
onSubmit() {
this.userService.createUser(this.addForm.value)
.subscribe( data => {
this.router.navigate(['list-user']);
this.showMsg= true;
});
}
then you can use showMsg boolean to show/hide dive like below
<div class="col-md-6">
<div ng-click=="onSubmit()">
<div class="row" *ngIf="showMsg">
<div class="col-xs-12">
<p class="alert alert-success">
<strong>Registration Success!</strong> Please click here to login!.
</p>
</div>
</div>
<button class="btn btn-success">Add user</button>
</div>
</div>
note that I am using some bootstrap classes for styling.
Yes function must return something . If you want a better option , you can use toast or popover .
Do this,
<div class="alert alert-success" ng-show='cts.showmsg == true'>{{cts.success_info}}</div>
You can use one boolean variable to show/hide message.
Angular Js:
$scope.successmessage = function(){
$scope.cts = [];
$scope.cts.success_info = "Data Successfully got updated";
$scope.cts.showmsg = true;
}
If you want to display in popup or modal, then there is best library in angular called ngDialog

I am working on an asp.net MVC core web application, and i added a captcha as follow:-
<div class="form-group">
<div class="col-md-2"></div>
<div class="col-md-10">
<span class="msg-error error"></span>
<div id="recaptcha" class="g-recaptcha" data-callback="recaptchaCallback" data-sitekey="#ViewData["ReCaptchaKey"]"></div>
</div>
</div>
also i added the following javascript validation to force a required on the captcha:-
$('#getmyestimate').click(function () {
var $captcha = $('#recaptcha'),
response = grecaptcha.getResponse();
if (response.length === 0) {
$('.msg-error').text("reCAPTCHA is mandatory");
if (!$captcha.hasClass("error")) {
$captcha.addClass("error");
}
} else {
$('.msg-error').text('');
$captcha.removeClass("error");
alert('reCAPTCHA marked');
}
})
as follow:-
but what i am trying to do , is that once the user select the captcha to remove the validation error (if any),, so can anyone advice how i can do so?
You can hide inside your callback recaptchaCallback function that you have already added in data-callback attribute in the g-recaptcha class.
var recaptchaCallback = function() {
$('#recaptcha').removeClass("error");
... //Any other code in the callback
}
I have a <div> on my page for alert message:
<div ng-controller="PercentageOverrideController as ctrl">
<script type="text/ng-template" id="alert.html">
<div class="alert" style="background-color:#fa39c3;color:white" role="alert">
<div ng-transclude></div>
</div>
</script>
<uib-alert ng-repeat="alert in alerts" type="{{alert.type}}" close="closeAlert($index)">{{alert.msg}}</uib-alert>
<button type="button" class='btn btn-default' ng-click="addAlert()">Add Alert</button>
</div>
In my Angular controller I have a variable $scope.alerts = [ ] and function which pushes a new alert message to an array:
$scope.showSuccess = function(){
$scope.alerts.push({type: 'success', msg: 'Threshold Overrided'});
};
$scope.showError = function(){
$scope.alerts.push({type: 'danger', msg: 'Error has been happened'});
};
After I make a request and get a response, I check in debug mode that the function was invoked and that a new value was added to the array. However it does not appear on my page.
I have a test button in my div:
<button type="button" class='btn btn-default' ng-click="addAlert()">Add Alert</button>
If I press this button, the alert appears on the page. If I try to invoke the same function:
$scope.addAlert = function() {
$scope.alerts.push({msg: 'Another alert!'});
};
within the code:
$scope.showSuccess = function(){
$scope.alerts.push({type: 'success', msg: 'Threshold Overrided'});
$scope.addAlert();
};
but the alert does not appear on page.
I assume that I should trigger somehow the view to show that update on page. What do you think guys?
Thank you!
You can use $scope.apply()
$scope.showSuccess = function(){
$scope.alerts.push({type: 'success', msg: 'Threshold Overrided'});
$scope.addAlert();
$scope.apply();
};
Instead of <div ng-controller="PercentageOverrideController as ctrl">
try <div ng-controller="PercentageOverrideController">
you need to run a digest loop.
$scope.$apply()
or alternatively
$scope.$digest()
should do it.
I have the following problem, I want to call a function of another controller from within a controller I want to use for a guided tour (I'm using ngJoyRide for the tour). The function I want to call in the other controller is so to say a translator (LanguageController), which fetches a string from a database according to the key given as parameter. The LanguageController will, if the key is not found, return an error that the string could not be fetched from the database. In my index.html fetching the string works, but I want to use it in the overlay element of my guided tour, which does not work, but only shows the "not fetched yet"-error of the LanguageController.
My index.html looks like this:
<body>
<div class="container-fluid col-md-10 col-md-offset-1" ng-controller="LangCtrl as lc" >
<div ng-controller="UserCtrl as uc" mail='#email' firstname='#firstname'>
<div ng-controller="GuidedTourCtrl as gtc">
<div ng-joy-ride="startJoyRide" config="config" on-finish="onFinish()" on-skip="onFinish()">
...
{{lc.getTerm('system_lang_edit')}}
...
</div>
</div>
</div>
</div>
</body>
The controller I'm using for the guided Tour looks like this:
guidedTourModule.controller('GuidedTourCtrl',['$scope', function($scope) {
$scope.startJoyRide = false;
this.start = function () {
$scope.startJoyRide = true;
}
$scope.config = [
{
type: "title",
...
},
{
type: "element",
selector: "#groups",
heading: "heading",
text: " <div id='title-text' class='col-md-12'>\
<span class='main-text'>"\
+ $scope.lc.getTerm('system_navi_messages') + "\
text text text text\
</span>\
<br/>\
<br/>\
</div>",
placement: "right",
scroll: true,
attachToBody: true
}
];
...
}]);
And the output I ultimately get looks like this for the overlay element:
<div class="row">
<div id="pop-over-text" class="col-md-12">
<div id='title-text' class='col-md-12'>
<span class='main-text'>
not fetched yet: system_navi_messages
text text text text
</span>
<br/>
<br/>
</div>
</div>
</div>
...
I hope someone can see the error in my code. Thanks in advance!
Things needs clarity are,
How you defined the 'getTerm' function in your Language controller, either by using this.getTerm() or $scope.getTerm(). Since you are using alias name you will be having this.getTerm in Language controller.
Reason why you are able to access the getTerm function in your overlay element is, since this overlay element is inside the parent controller(Language Controller) and you are referencing it with alias name 'lc' while calling the getTerm function. Thats' why it is accessible.
But the string you pass as a parameter is not reachable to the parent controller. that's why the error message is rendered in the overlay HTML.
Please make a plunker of your app, so that will be helpful to answer your problem.
I am doing a functionality of selecting an image from the image list. I have a button "select" from every button and call selectImage method on button-click.
AngularApp:
app = angular.module("BlogImageApp", []);
app.controller("BlogImageController", function($http, $scope){
$scope.selectedImageId = null;
$scope.selectedImageUrl = "";
$scope.selectImage = function(image_id) {
$scope.selectedImageId = image_id;
var params = 'id='+image_id;
$http.get('/blog/image/get-url-by-id?'+params).success(function(data){
$scope.selectedImageUrl = data;
});
}
});
// registers the BlogImageApp in the view
angular.bootstrap(document, ['BlogImageApp']);
The view:
<div id="blog-images" ng-controller="BlogImageController">
<div ng-show="selectedImageId == null" style="height:50px; margin-bottom:5px;">
<div class="alert alert-info">
<span class="glyphicon glyphicon-info-sign"></span>
The image isn't selected!
</div>
</div>
<div class="blog-selected-image" ng-hide="selectedImageUrl == ''">
<b>The selected image: <span ng-bind="selectedImageUrl"></span> </b><br/>
<img ng-src="{{selectedImageUrl}}" class="img-thumbnail" style="height:200px">
</div>
...
PJAX PART GOES HERE WITH GRID AND PAGINATION
and button with ng-click="selectImage(39)" for every item
PJAX PART ENDS
And after all in javascript:
var ngRefresh = function() {
var scope = angular.element(document.body).scope();
var compile = angular.element(document.body).injector().get('$compile');
compile($(document.body).contents())(scope);
scope.$apply();
}
// PJAX
$(document.body).on('pjax:success', function(e){
ngRefresh();
});
After pjax call I have some strange behaviour. When I click a select button, selectImage method is invoked. It changes selectedIMageUrl and I can see different url in span every time I click select button. But the image (where ng-src specified) doesn't change.
Image changing worked great before pjax call though.
PS: I understand, that it would be better to do jsFiddle snippet, but I would have problem with server side.
I have the following HTML
<div class="alert alert-danger col-sm-10 col-sm-offset-1" ng-show="showErrorMessage">
<button data-dismiss="alert" class="close" ng-click="closeErrorMessage()">
×
</button>
<i class="fa fa-check-circle"></i>
<strong>Error</strong> The following errors have occurred:
<div ng-repeat="error in createResp.Errors">{{error}}</div>
</div>
With the following inside my JavaScript
$scope.showErrorMessage = false;
$scope.search = function () {
var createOrderResp = myData.create($scope.request);
createOrderResp.$promise.then(function (r) {
$scope.createResp = r;
if ($scope.createResp.Errors.length > 0) {
$scope.showErrorMessage = true;
}
}, function (r) {
handleResourceError(r);
});
};
$scope.closeErrorMessage = function () {
$scope.showErrorMessage = false;
};
So everything works fantastic the first time through. If the response contains errors then the div is shown. However after clicking the close button closeErrorMessage() and then performing it again the error alert does not show up even though the showErrorMessage flag turns to true.
The issue is with data-dismiss. It will remove entire alert block. Therefore triggering ng-show with variable in scope won't help, since there won't be an html part, that will need triggering.
