How to show and hide <div>'s in Popover using AngularJS - html

Question

I am working on SPA (Single Page Application) for Online Team Collaboration service(OTC) ,and I include HTML pages by ng-include,in some included page there is a popover ,this one contains a possibility for creating a public group chat,and in order to create one ,the user must submit, now my question is : how can i display a "successfully created" message in the same popover instead of the main div for creating the group in the popover?
The external page (the page that include other pages):
<div ng-show="ctrChanneldiv" ng-contoller="ctrChannelCon" style="float: right;" class="col-md-3">
<div ng-include="'CreateChannel.html'" ></div>
</div>
The Controller ctrChannelCon:
appvar.controller('ctrChannelCon',['$scope','$http','$rootScope',function($scope, $http, $rootScope){
$scope.createBtn = function() {
$http.post("http://localhost:8080/ExampleServletv3/crtchannelservlet",this.crtchannel)
.success(function(response) {
setTimeout(function () {
$scope.$apply(function(){
//******* Here Display "Successfully Created" In the Popover *******//
});
});
});
};
}]);
In CreateChannel.html :
<div>
<div class="row">
<a href="#" class="popper" data-toggle="popover"
data-placement="bottom"><span class="glyphicon glyphicon-plus"></span>Create Channel</a>
<div class="popper-content hide">
<div class="form-group">
<!-- ng-controller="createChannelCon" -->
<div class="form-group">
<label>Channel name:</label>
</div>
<div class="form-group">
<input ng-model="crtchannel.Name" type="text" placeholder="enter channel's name" maxlength="30"
class="form-control input-md" required />
</div>
<div class="form-group">
<label>Description:</label>
</div>
<div class="form-group">
<textarea cols="15" ng-model="crtchannel.Description" type="text"
placeholder="enter channel's description" maxlength="500"
class="form-control input-md" required></textarea>
</div>
<div>
<input ng-model="crtchannel.Type" type="radio" name="chtype"
value="private" required /> Private<br> <input
ng-model="crtchannel.Type" type="radio" name="chtype"
value="public" /> Public<br>
</div>
<div class="form-group">
<button ng-click="createBtn()" class="btn btn primary">Apply</button>
</div>
</div>
</div>
<script>
$('.popper').popover({
container : 'body',
html : true,
content : function() {
return $(this).next('.popper-content').html();
}
});
</script>
</div>
</div>
Any suggestions?
Thanks

You may use ngClass directive to counter this problem. ngClass directive allows conditional application of classes. Create a div for successfully created in the popup and set up ng-class directive with a variable in the scope and assign it true and false as per your requirement.
JS
appvar.controller('ctrChannelCon',['$scope','$http','$rootScope',function($scope, $http, $rootScope){
$scope.createBtn = function() {
$http.post("http://localhost:8080/ExampleServletv3/crtchannelservlet",this.crtchannel)
.success(function(response) {
setTimeout(function () {
$scope.$apply(function(){
//******* Change value of a model *******//
$scope.hidden = false;
});
});
});
};
}]);
HTML
<span ng-class="{hide: hidden}">Successfully Created</span>
CSS
.hide { display: none; }

Set a flag in your controller on success and use this flag to show or hide the success message:
...
<div class="form-group">
<button ng-click="createBtn()" class="btn btn primary">Apply</button>
</div>
<div ng-show="isSuccess">Successfully Created</div>
Inside the controller:
$scope.isSuccess = false;
$scope.createBtn = function() {
$http.post("http://localhost:8080/ExampleServletv3/crtchannelservlet",this.crtchannel)
.success(function(response) {
setTimeout(function () {
$scope.$apply(function(){
//******* Here Display "Successfully Created" In the Popover *******//
$scope.isSuccess = true;
});
});
});
};
