I have an md-select that has inside it an md-option. In the md-option tag I have an ng-click that points to my function that is defined. The problem is that it seems to never get to my function when I click an option from the list.
Here is my html:
<div class="panel-body">
<md-select placeholder="{{getIntervalName()}}" ng-model="intervalSelected">
<md-option ng-repeat="item in intervals" value="{{item.name}}" ng-click="changeInterval(item)">
{{item.name}}
</md-option>
</md-select>
<div style="overflow: auto;">
<div id="parentDivChart" style="{{changeWidth()}};height:400px">
<canvas id="bar" class="chart chart-bar" chart-data="datta"
chart-labels="labels" chart-options="myoptions" chart-legend="legend">
</canvas>
<div tc-chartjs-legend chart-legend="legend"></div>
</div>
</div>
</div>
And this is my function defined in the controller:
function changeInterval(item) {
console.log("change intervaaaalll");
$scope.default_interval ="day";
intrvl = item.value;
setItem("interval", item.value);
$scope.loadChart();
};
It does not write to the console anything, that means it never reaches my function. Does anybody have an idea why ?
Thanks in advance!
It would have been better if you had provided the code where you create the controller.
However, I think you should create the method changeInterval(item) in this way:
var nameOfYourApp = angular.module(‘nameOfYourApp’, []);
nameOfYourApp.controller('nameOfYourController', function($scope) {
$scope.changeInterval = function(item) {
console.log("change intervaaaalll");
$scope.default_interval ="day";
intrvl = item.value;
setItem("interval", item.value);
$scope.loadChart();
}
});
Hope this helps!
As you want to use the changeInterval method on the scope you have to add it to the scope as follows:
In the controller:
$scope.changeInterval(item) {
console.log("change intervaaaalll");
$scope.default_interval ="day";
intrvl = item.value;
setItem("interval", item.value);
$scope.loadChart();
};
Don't forget to include $scope as a dependency for your controller.
E.g.:
app.controller('myCtrl', function($scope) {
});
Now as the changeInterval function is assigned to a variable on the scope it can be invoked on the view.
Since you changeInterval() is a private function to the controller, you can't access it. You need to make it public (bind it to a variable of the controller).
You should go with this approach:
$scope.changeInterval = changeIntervalapproach;
If you're using the view model approach with controllerAs then use:
vm.changeInterval = changeInterval;
Write "$scope.changeInterval=changeInterval;" in your controller
or
use "$scope.changeInterval=function (item) {...};"

Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?
This comes from a requirement to turn an inconsistent JSON blob into a nested list of id: value pairs. Therefore the HTML is created in the controller and I am now looking to display it.
I have created a model property, but cannot render this in the view without it just printing the HTML.
Update
It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.
Example controller :
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
Example view :
<div ng:bind="customHtml"></div>
Gives :
<div>
"<ul><li>render me please</li></ul>"
</div>
For Angular 1.x, use ng-bind-html in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
At this point you would get a attempting to use an unsafe value in a safe context error so you need to either use ngSanitize or $sce to resolve that.
$sce
Use $sce.trustAsHtml() in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
There are 2 steps:
include the angular-sanitize.min.js resource, i.e.:
<script src="lib/angular/angular-sanitize.min.js"></script>
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services',
'myApp.directives', 'ngSanitize'])
You can also create a filter like so:
var app = angular.module("demoApp", ['ngResource']);
app.filter("trust", ['$sce', function($sce) {
return function(htmlCode){
return $sce.trustAsHtml(htmlCode);
}
}]);
Then in the view
<div ng-bind-html="trusted_html_variable | trust"></div>
Note: This filter trusts any and all html passed to it, and could present an XSS vulnerability if variables with user input are passed to it.
Angular JS shows HTML within the tag
The solution provided in the above link worked for me, none of the options on this thread did. For anyone looking for the same thing with AngularJS version 1.2.9
Here's a copy:
Ok I found solution for this:
JS:
$scope.renderHtml = function(html_code)
{
return $sce.trustAsHtml(html_code);
};
HTML:
<p ng-bind-html="renderHtml(value.button)"></p>
EDIT:
Here's the set up:
JS file:
angular.module('MyModule').controller('MyController', ['$scope', '$http', '$sce',
function ($scope, $http, $sce) {
$scope.renderHtml = function (htmlCode) {
return $sce.trustAsHtml(htmlCode);
};
$scope.body = '<div style="width:200px; height:200px; border:1px solid blue;"></div>';
}]);
HTML file:
<div ng-controller="MyController">
<div ng-bind-html="renderHtml(body)"></div>
</div>
Fortunately, you don't need any fancy filters or unsafe methods to avoid that error message. This is the complete implementation to properly output HTML markup in a view in the intended and safe way.
The sanitize module must be included after Angular:
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular-sanitize.js"></script>
Then, the module must be loaded:
angular.module('app', [
'ngSanitize'
]);
This will allow you to include markup in a string from a controller, directive, etc:
scope.message = "<strong>42</strong> is the <em>answer</em>.";
Finally, in a template, it must be output like so:
<p ng-bind-html="message"></p>
Which will produce the expected output: 42 is the answer.
I have tried today, the only way I found was this
<div ng-bind-html-unsafe="expression"></div>
ng-bind-html-unsafe no longer works.
This is the shortest way:
Create a filter:
myApp.filter('unsafe', function($sce) { return $sce.trustAsHtml; });
And in your view:
<div ng-bind-html="customHtml | unsafe"></div>
P.S. This method doesn't require you to include the ngSanitize module.
on html
<div ng-controller="myAppController as myCtrl">
<div ng-bind-html-unsafe="myCtrl.comment.msg"></div>
OR
<div ng-bind-html="myCtrl.comment.msg"></div
on controller
mySceApp.controller("myAppController", function myAppController( $sce) {
this.myCtrl.comment.msg = $sce.trustAsHtml(html);
works also with $scope.comment.msg = $sce.trustAsHtml(html);
I found that using ng-sanitize did not allow me to add ng-click in the html.
To solve this I added a directive. Like this:
app.directive('htmldiv', function($compile, $parse) {
return {
restrict: 'E',
link: function(scope, element, attr) {
scope.$watch(attr.content, function() {
element.html($parse(attr.content)(scope));
$compile(element.contents())(scope);
}, true);
}
}
});
And this is the HTML:
<htmldiv content="theContent"></htmldiv>
Good luck.
Just did this using ngBindHtml by following angular(v1.4) docs,
<div ng-bind-html="expression"></div>
and expression can be "<ul><li>render me please</li></ul>"
Make sure you include ngSanitize in the module's dependencies.
Then it should work fine.
Another solution, very similar to blrbr's except using a scoped attribute is:
angular.module('app')
.directive('renderHtml', ['$compile', function ($compile) {
return {
restrict: 'E',
scope: {
html: '='
},
link: function postLink(scope, element, attrs) {
function appendHtml() {
if(scope.html) {
var newElement = angular.element(scope.html);
$compile(newElement)(scope);
element.append(newElement);
}
}
scope.$watch(function() { return scope.html }, appendHtml);
}
};
}]);
And then
<render-html html="htmlAsString"></render-html>
Note you may replace element.append() with element.replaceWith()
there is one more solution for this problem using creating new attribute or directives in angular.

Use
<div ng-bind-html="customHtml"></div>
and
angular.module('MyApp', ['ngSanitize']);
For that, you need to include angular-sanitize.js,
for example in your html-file with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-sanitize.js"></script>
Here's a simple (and unsafe) bind-as-html directive, without the need for ngSanitize:
myModule.directive('bindAsHtml', function () {
return {
link: function (scope, element, attributes) {
element.html(scope.$eval(attributes.bindAsHtml));
}
};
});
Note that this will open up for security issues, if binding untrusted content.
Use like so:
<div bind-as-html="someHtmlInScope"></div>

Before you needed to use ng-bind-html...
I'm using templates based on my JSON. So, I can't really use my ng-bind-html like I would normally do.
Seems like the only option I have is to use my sanitized html inside an directive.
Looking for similar questions, I couldn't figure it out how to apply in my case.
Yes, I am pretty newbie into angular.
I'm currently receiving this data from my controller:
$scope.safecontainers = $sanitize($scope.containersmsg);
In my html would normally be like this:
<p ng-bind-html="containersmsg"></p>
But I don't want this, I need to use this ng-bind-html inside a directive!
Some people have talked about $compile, but I couldn't really figure it out how to apply in my case.
EDIT:
Based on comments, i'll add more code to help you guys further understand my goal.
Inside my index.html I'm declaring the controllers needed and calling my
<ng-view></ng-view>
Then, based on what I receive, i'll load one view or another:
<div ng-if='setores[0].SetorTema == "1"'>
<theme-one titulo="{{setores[0].SetorNome}}" logo="
{{setores[0].SetorLogo}}" evento="{{evento[0].EventoNome}}">
</theme-one>
// I omitted some of the parameters because they ain't relevant
</div>
My template is like this: (Just a little part of it to avoid much useless code)
<section class="target">
<div class="col-md-6 col-xs-12">
<div class="" ng-repeat="banner in title">
<div class="target-title">{{ banner.BannerLevelTitulo }}
</div>
<div class="target-desc">{{banner.BannerLevelDescricao}}</div>
</div>
</div>
<div class="col-md-6 col-xs-hidden">
<div class="target-image"><img ng-src="{{targetimage}}" alt="">
</div>
</div>
</section>
This is the controller I want my sanitized code.
hotsite.controller('containerController', function($scope, $http, $sanitize)
{
$scope.containers = [];
$scope.containersmsg = '';
$scope.safecontainers = $sanitize($scope.containersmsg);
$http.get('/Admin/rest/getContainer')
.then(function onSuccess(response) {
var data = response.data;
$scope.containers = data;
$scope.containers = response.data.filter(containers =>
containers.ContainerAtivo);
$scope.containersmsg = $scope.containers[0].ContainerDesc;
})
.catch(function onError(response) {
var data = response.data;
console.log(data);
});
});
This is a piece of my directive:
angular.module('hotsiteDirectives', [])
.directive('themeOne', function($compile) {
var ddo = {};
ddo.restrict = "AE";
ddo.transclude = true;
ddo.scope = {
titulo: '#',
...
(a lot of other scope's)
contimg: '#'
};
ddo.templateUrl = 'app/directives/theme-one.html';
return ddo;
})
And yes, I am calling the ngSanitize
var hotsite = angular.module('hotsite',['ngRoute', 'hotsiteDirectives',
'ngSanitize']);
TL;DR
This is how my code looks like inside a directive, with raw html and not rendered:
This is how it works with ng-bind-html, formatted html
If I do put this inside my view
<p ng-bind-html="containersmsg"></p>
It will be alright, all of it working like it should.
BUT, I need to call this only inside my directive, and I don't know how to do it.
So, with this context:
How can I put my sanitized html inside my directive and template?
You don't even have to trust the html to render it using ngBindHtml because the directive already does it for you. You basically need to create a parameter attribute for your directive to hold the html string, so, inside the directive's template, you use ng-bind-html="myParam".
The following snippet implements a simple demonstration of creating a directive that receives and renders an html input parameter that comes from a controller.
angular.module('app', ['ngSanitize'])
.controller('AppCtrl', function($scope) {
$scope.myHtml = '<div><b>Hello!</b> I\'m an <i>html string</i> being rendered dynamicalli by <code>ngBindHtml</code></div>';
})
.directive('myDirective', function() {
return {
template: '<hr><div ng-bind-html="html"></div><hr>',
scope: {
html: '='
}
};
});
<div ng-app="app" ng-controller="AppCtrl">
<my-directive html="myHtml"></my-directive>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0/angular-sanitize.js"></script>
I want to bind an array (customLayers) and use it for ng-repeat.
I fill the array inside the kv.colorMap Object.
I have three directives using these technique. But the directive updates the binded array on view ONLY after pressing a functionless button (checkResult), which is inside this directive.
Directive Template Code:
...
<div class="createInfo colorExprContainer">
<div ng-repeat="layer in customLayers">{{layer.color}}</div>
</div>
<div class="buttonWrapper text-center">
<button class="btn" ng-click="checkResult()">Ergebnis prüfen</button>
</div>
...
Directive JavaScript Code:
app.directive('boolKv', function($parse, $timeout){
return {
restrict: 'E',
replace:true,
scope:true,
templateUrl: "directives/boolKV/boolKV.html",
link: function($scope, $element, $attr) {
...
var kv = new BAKV({target: cv[0].id, expr: expr});
$scope.customLayers = kv.colorMap.layers;
...
$scope.checkResult = function(){console.log("it works!");};
});
Does someone have an idea?
Thank you very much!
Thank you MirMasej!
You were right, I was calling it after render. Maybe because I've used the EaselJs Library for canvas. I wanted to get the update after click on a block inside this canvas.
I solved it by adding, if someone has a better idea I would try it:
kv.colorMap.onChangedLayer = function(layer) {
$timeout(function(){
$scope.$apply();
});
};
Im calling this onChangedLayer event after changing the data inside the colorMap object.
I am new to AngularJS and have some trouble understanding the concept of scope in Angular. I have read some posts on stackoverflow as well as online articles, which advise me to create a custom directive to create an isolate scope, but I am getting nowhere...
As for the project I'm working on, I am trying to make a button that when clicked, will trigger a textarea. However, because of ng-repeat, the textarea is triggered for all buttons while I click only one.
My .js file:
angular.module('myApp')
.controller('myCtrl', function ($scope, Question) {
scope.visible = false;
scope.toggle = function() {
scope.visible = !scope.visible;
};
.directive("myDirective", function () {
return {
scope: {
ngClick: '&',
ngShow: '&'
}
}
});
Here is my HTML file:
<ul>
<li ng-repeat="object in objectList">
<button type="text" myDirective ng-click="toggle()">Click</button>
<textarea myDirective ng-show="visible"></textarea>
</li>
</ul>
Angular is creating child (NOT isolated) scope when ng-repeating, try this out, when you ng-init a variable, it is only visible within that repeat div.
<div ng-repeat="i in [0,1,2,3,4,5,6,7,8,9]" ng-init="visible=false">
<button ng-click="visible=!visible">Toggle</button>
<h1 ng-show="visible">look at me!</h1>
</div>

There is no need to use a directive. You need to use object in the foreach to refer each item in the loop.
Add visible to each object in objectList:
$scope.objectList = [
{ visible: false },
{ visible: false },
{ visible: false }
];
Then the toggle button will need to pass the object to toggle:
$scope.toggle = function (object) {
object.visible = !object.visible;
};
The ng-show will need to check object.visible and ng-click will need to pass the object:
<button type="text" ng-click="toggle(object)">Click</button>
<textarea ng-show="object.visible"></textarea>
