I try to replace the html template into an angular directive to use a custom JointJS graph as html and not a regular JointJS objects. The following code is an example i found on the web which works great under JS and jQ, but when I try to replace that to an angular directive it doesnt render the code or worse, it duplicates the html table (when i run addCell func) but not drawing the table elm on the Graph. It also looks like the css rules are not being rendered to provide the new styles.
Any ideas pls ?
//an example for creating JoinJS obj with HTML template
joint.shapes.html = {};
joint.shapes.html.Element = joint.shapes.basic.Rect.extend({
defaults: joint.util.deepSupplement({
type: 'html.Element',
attrs: {
rect: { stroke: 'none', 'fill-opacity': 0 }
}
}, joint.shapes.basic.Rect.prototype.defaults)
});
// Create a custom view for that element that displays an HTML div above it.
// -------------------------------------------------------------------------
joint.shapes.html.ElementView = joint.dia.ElementView.extend({
template: [
// trying to convert the TABLE elem below to an angular directive
//'<container-data></container-data>'
'<table class="html-element"><tr><td><form onsubmit="return false;" action="">',
'<button class="delete">x</button>',
'<label></label>',
'<i class="link_add" title="Add a link">L</i>',
'<div class="section_title">Properties <i class="fa fa-caret-down fRight"></i></div>'
'</form></td></tr></table>'
].join(''),
// some funcs come here
});
$scope.loadBalancer = new joint.shapes.html.Element({position: { x: 20, y: 20 }, size: { height: 30 }, label: 'LoadBalancer', select: 'one' });
$scope.graph.addCells([$scope.loadBalancer]);

Here is my simplified template:
<div>
<img ng-click="addSubPlots($event)"
data-status="add"
src="abc.svg" />
</div>
And here is a directive that loads that template:
a.directive("trendChartToolbar", function ($templateRequest, $compile) {
return {
link: function (scope, elem, attrs) {
$templateRequest('template.html').then(function (html) {
var template = angular.element(html);
$(elem).append(template);
template = $compile(template)(scope);
});
}
};
});
My expectation was that I would be able to access template's dataset and modify the 'status' key. But when I check it the dataset is empty. I know that Angular removes 'data-' but I also dont see any 'status' anywhere. Any idea how to make something like this working? The reason I am trying this is when I click on a button I need to get button's status. Here is code I am using in the controller:
$scope.addSubPlots = function(event){
console.log(event.target.dataset.status);
}
Please share some ideas.
Thanks
I'm working on a website using a MEAN stack, and now I am trying to show some MongoDB data in my HTML pages by using Angular. But I don't seem to get it done.
This is the data in MongoDB I want to show in my HTML
{
"badkamer" : {
"block1" : {
"title" : "Badkamer",
"content" : "string"
}
}
}
This is the Angular function retrieving the data:
app.controller('cityCtrl', function($scope,$http){
$scope.specials = function(){
$scope.special = [];
$http.get('/specialdata').then(function(d){
$scope.special = d.data;
console.log(d.data);
},function(err){
console.log(err);
});
};
});
This is where I want it to show in my HTML:
<div ng-controller="cityCtrl" ng-init="specials()" ng-bind="special">
<div class="title">{{special.badkamer.block1.title}}</div>
<p>{{special.badkamer.block1.content}}</p>
</div>
</div>
When i console.log(d.data), I get this:
[Object]
0: Object
badkamer: Object
block1: Object
content: "Text",
title: "Badkamer"
But when I try it like this, the bind option shows all the data at once in my HTML. How can I get it working by using the Angular {{}} tags?
From the console.log, you can see that its an array, so you will need to use index, like this,
<div ng-controller="cityCtrl" ng-init="specials()" ng-bind="special">
<div class="title">{{special[0].badkamer.block1.title}}</div>
<p>{{special[0].badkamer.block1.content}}</p>
</div>
</div>
or change the code in controller.,
$scope.special = d.data[0];
I have written the following piece of code to display some contents in angular material dialog box. it works fine when i add plain text to textContent . when i add HTML its displays HTML as text. how do i bind HTML to textContent
This Works
Sample Link
$scope.Modal = function () {
$mdDialog.show(
$mdDialog.alert()
.parent(angular.element(document.querySelector('body')))
.clickOutsideToClose(true)
.textContent('sample text')
.ok('Ok')
);
}
This Doesn't Works
Sample Link
$scope.Modal = function () {
$mdDialog.show(
$mdDialog.alert()
.parent(angular.element(document.querySelector('body')))
.clickOutsideToClose(true)
.textContent('<div class="test"><p>Sample text</p></div>')
.ok('Ok')
);
}
Thanks in advance
You need to append to the template,
$mdDialog.show({
parent: angular.element(document.body),
clickOutsideToClose: true,
template: '<md-dialog md-theme="mytheme">' +
' <md-dialog-content>' +
'<div class="test"><p>Sample text</p></div>' +
' <md-button ng-click="closeDialog();">Close</md-button>' +
' </md-dialog-content>' +
'</md-dialog>',
locals: {
},
controller: DialogController
});

You can add html in template and just add variable in displayOption. This will work.
Template Code
<script type="text/ng-template" id="confirm-dialog-answer.html">
<md-dialog aria-label="confirm-dialog">
<form>
<md-dialog-content>
<div>
<h2 class="md-title">{{displayOption.title}}</h2>
<p>{{displayOption.content}} <img src="{{displayOption.fruitimg}}"/></p>
<p>{{displayOption.comment}}</p>
</div>
</md-dialog-content>
<div class="md-actions" layout="row">
<a class="md-primary-color dialog-action-btn" ng-click="cancel()">
{{displayOption.cancel}}
</a>
<a class="md-primary-color dialog-action-btn" ng-click="ok()">
{{displayOption.ok}}
</a>
</div>
</form>
</md-dialog>
</script>
Controller Code
$mdDialog.show({
controller: 'DialogController',
templateUrl: 'confirm-dialog-answer.html',
locals: {
displayOption: {
title: "OOPS !!",
content: "You have given correct answer. You earned "+$scope.lastattemptEarnCount,
comment : "Note:- "+$scope.comment,
fruitimg : "img/fruit/"+$scope.fruitname+".png",
ok: "Ok"
}
}
}).then(function () {
alert('Ok clicked');
});
Use template instead of textContent, textContent is used for show plan text in a model. It does not render HTML code
$mdDialog.show({
controller: function ($scope) {
$scope.msg = msg ? msg : 'Loading...';
},
template: 'div class="test"><p>{{msg}}</p></div>',
parent: angular.element(document.body),
clickOutsideToClose: false,
fullscreen: false
});
You can use htmlContent instead of textContent to render HTML. Heres an excerpt from the documentation available at https://material.angularjs.org/latest/#mddialog-alert
$mdDialogPreset#htmlContent(string) - Sets the alert message as HTML.
Requires ngSanitize module to be loaded. HTML is not run through
Angular's compiler.
It seems a bit counter intuitive to use a template when you only need to inject one or two things in. To avoid using a template, you need to include 'ngSanitize' for it to work.
angular.module('myApp',['ngMaterial', 'ngSanitize'])
.controller('btnTest',function($mdDialog,$scope){
var someHTML = "<font>This is a test</font>";
$scope.showConfirm = function(ev) {
// Appending dialog to document.body to cover sidenav in docs app
var confirm = $mdDialog.confirm()
.title('Please confirm the following')
.htmlContent(someHTML)
.ariaLabel('Lucky day')
.targetEvent(ev)
.ok('Please do it!')
.cancel('Sounds like a scam');
//Switch between .htmlContent and .textContent. You will see htmlContent doesn't display dialogbox, textContent does.
$mdDialog.show(confirm).then(function() {
$scope.status = 'Saving Data';
},
function() {
$scope.status = 'You decided to keep your debt.';
});
};
})
Notice the injected HTML:
var someHTML = "<font>This is a test</font>";
I found this example here.
The latest version of Angular Material Design API has predefined function for add HTML content to the alert dialog:
an $mdDialogPreset with the chainable configuration methods:
$mdDialogPreset#title(string) - Sets the alert title.
$mdDialogPreset#textContent(string) - Sets the alert message.
$mdDialogPreset#htmlContent(string) - Sets the alert message as HTML. Requires ngSanitize module to be loaded. HTML is not run through Angular's compiler.
$mdDialogPreset#ok(string) - Sets the alert "Okay" button text.
$mdDialogPreset#theme(string) - Sets the theme of the alert dialog.
$mdDialogPreset#targetEvent(DOMClickEvent=) - A click's event object. When passed in as an option, the location of the click will be used as the starting point for the opening animation of the the dialog.

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>
Plunker
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>
Plunkr
The Situation
Nested within our Angular app is a directive called Page, backed by a controller, which contains a div with an ng-bind-html-unsafe attribute. This is assigned to a $scope var called 'pageContent'. This var gets assigned dynamically generated HTML from a database. When the user flips to the next page, a called to the DB is made, and the pageContent var is set to this new HTML, which gets rendered onscreen through ng-bind-html-unsafe. Here's the code:
Page directive
angular.module('myApp.directives')
.directive('myPage', function ($compile) {
return {
templateUrl: 'page.html',
restrict: 'E',
compile: function compile(element, attrs, transclude) {
// does nothing currently
return {
pre: function preLink(scope, element, attrs, controller) {
// does nothing currently
},
post: function postLink(scope, element, attrs, controller) {
// does nothing currently
}
}
}
};
});
Page directive's template ("page.html" from the templateUrl property above)
<div ng-controller="PageCtrl" >
...
<!-- dynamic page content written into the div below -->
<div ng-bind-html-unsafe="pageContent" >
...
</div>
Page controller
angular.module('myApp')
.controller('PageCtrl', function ($scope) {
$scope.pageContent = '';
$scope.$on( "receivedPageContent", function(event, args) {
console.log( 'new page content received after DB call' );
$scope.pageContent = args.htmlStrFromDB;
});
});
That works. We see the page's HTML from the DB rendered nicely in the browser. When the user flips to the next page, we see the next page's content, and so on. So far so good.
The Problem
The problem here is that we want to have interactive content inside of a page's content. For instance, the HTML may contain a thumbnail image where, when the user clicks on it, Angular should do something awesome, such as displaying a pop-up modal window. I've placed Angular method calls (ng-click) in the HTML strings in our database, but of course Angular isn't going to recognize either method calls or directives unless it somehow parses the HTML string, recognizes them and compiles them.
In our DB
Content for Page 1:
<p>Here's a cool pic of a lion. <img src="lion.png" ng-click="doSomethingAwesone('lion', 'showImage')" > Click on him to see a large image.</p>
Content for Page 2:
<p>Here's a snake. <img src="snake.png" ng-click="doSomethingAwesone('snake', 'playSound')" >Click to make him hiss.</p>
Back in the Page controller, we then add the corresponding $scope function:
Page controller
$scope.doSomethingAwesome = function( id, action ) {
console.log( "Going to do " + action + " with "+ id );
}
I can't figure out how to call that 'doSomethingAwesome' method from within the HTML string from the DB. I realize Angular has to parse the HTML string somehow, but how? I've read vague mumblings about the $compile service, and copied and pasted some examples, but nothing works. Also, most examples show dynamic content only getting set during the linking phase of the directive. We would want Page to stay alive throughout the life of the app. It constantly receives, compiles and displays new content as the user flips through pages.
In an abstract sense, I guess you could say we are trying to dynamically nest chunks of Angular within an Angular app, and need to be able to swap them in and out.
I've read various bits of Angular documentation multiple times, as well as all sorts of blog posts, and JS Fiddled with people's code. I don't know whether I'm completely misunderstanding Angular, or just missing something simple, or maybe I'm slow. In any case, I could use some advice.
ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

app.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,

scope.$watch(attrs.dynamic, function(html) {
ele.html(html);
$compile(ele.contents())(scope);
});
}
};
});
function MyController($scope) {
$scope.click = function(arg) {
alert('Clicked ' + arg);
}
$scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}
In angular 1.2.10 the line scope.$watch(attrs.dynamic, function(html) { was returning an invalid character error because it was trying to watch the value of attrs.dynamic which was html text.
I fixed that by fetching the attribute from the scope property
scope: { dynamic: '=dynamic'},
My example
angular.module('app')
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'dynamic' , function(html){
element.html(html);
$compile(element.contents())(scope);
});
}
};
});
Found in a google discussion group. Works for me.
var $injector = angular.injector(['ng', 'myApp']);
$injector.invoke(function($rootScope, $compile) {
$compile(element)($rootScope);
});
You can use
ng-bind-html https://docs.angularjs.org/api/ng/service/$sce
directive to bind html dynamically.
However you have to get the data via $sce service.
Please see the live demo at http://plnkr.co/edit/k4s3Bx
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
$scope.getHtml=function(){
return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
}
});
<body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
</body>
Try this below code for binding html through attr
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'attrs.dynamic' , function(html){
element.html(scope.dynamic);
$compile(element.contents())(scope);
});
}
};
});
Try this element.html(scope.dynamic);
than element.html(attr.dynamic);
