I am trying to create a tooltip based from from this post
Angular-UI-Bootstrap custom tooltip/popover with 2-way data-binding
I successfully created the popup but I have trouble delivering the content to my popover.html
I added this to my script.js
var app = angular.module('myApp', ['ui.bootstrap', 'ian.bootstrap']);
app.controller('myCtrl', function ($scope) {
$scope.item = {
title: 'Original Title',
content:'content 1' //newly added item
};
$scope.text = 'Click me';
});
and I want to display it in my popover.html
<div class="popover-content">
{{item.content}}
</div>
It doesn't show anything. Can someone help me about it? thanks a lot!

Here is your updated working Plunkr
Basically you have to pass the attr iantooltip-content with the binding of the content item, not the raw text, and after in the directive pass in the directive isolate scope options the binding of the content like :
iantooltipContent: '='
Just change the appenToBody variable and you're done.
You should read the docs for more infos about Angular directive :)
You can add the ng-controller in your div and then specify the controller name like so :
<div class="popover-content" ng-controller='myCtrl'>
{{item.content}}
</div>
Before the use cases, the basic syntax to create a custom directive.
For all the code samples in this page I started from the angular-seed template.
Starting from the angular-seed skeleton is quite easy to extract a model to begin to implement custom directives.
<html ngApp="myApp">
...
<div my-first-directive></div>
<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="js/directives.js"></script>
...
</html>

I'm still fighting with simple things in Angular. I have jQuery and Backbonejs background, so please do not yell on me. I try hard to understand differences
I have HTML in which from rails is given ID of project as data-project-id:
<div data-ng-controller="ProjectCtrl as ctrl" data-project-id="1" id="project_configuration">
Is there any chance to get access to this attribute? I need it to my API calls...
To access an elements attributes from a controller, inject $attrs into your controller function:
HTML
<div test="hello world" ng-controller="ctrl">
</div>
Script
app.controller('ctrl', function($attrs) {
alert($attrs.test); // alerts 'hello world'
});
In your example, if you want to get data-project-id:
$attrs.projectId
Or if you want to get id:
$attrs.id
Demo:
var app = angular.module('app',[]);
app.controller('ctrl', function($attrs) {
alert($attrs.test);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl" test="hello world">
</div>
In Angular world you should use directives to manipulate with DOM elements. Here a nice explanation how to get attribute value from custom directive (How to get evaluated attributes inside a custom directive).
But if you still want to get it's value from controller you are able to use jQuery as well $('#project_configuration').data('project-id')
I have an ng-include which is bound to a scope variable.
I can change the included content dynamically through my own 'routing' system using this approach.
However angular animations are fired on enter and leave events and are not triggered simply when the binding changes for the ng-include.
what is the best approach to implementing this, some kind of custom directive that wraps the ng-include behaviour, or is there a simpler way to do this that I'm missing?
Here's the index html
<body ng-controller="MainCtrl">
<div ng-include="templateUrl" class="animation" ></div>
<br/><form>
<button ng-click="swapTemplate()">Swap</button>
</form>
</body>
and the controller code
$scope.templateUrl = 'page2.html';
$scope.swapTemplate = function() {
if($scope.templateUrl === 'page1.html'){
$scope.templateUrl = 'page2.html';
}
else {
$scope.templateUrl = 'page1.html';
}
}
And the plnk http://plnkr.co/edit/Oh1vKi0DCxj95qO1J23x
you need to add angular-animate.js file
<script data-require="angular-animate#*" data-semver="1.2.13" src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.3/angular-animate.js"></script>
add ngAnimate module in to main module
var app = angular.module('plunker', ['ngAnimate']);

Sorry, this seems a duplicated questions, but I tried all answered questions close to my question, with no success.
I am trying to introduce angular.js into a legacy system.
the system is using the .load jquery function to dynamically load div content with a page from an ASP.NET MVC page.
my brief html will look like this
<body ng-app="myApp">
<div ng-controller="myCtrl">
any content...
<div id="dyncontent"> </div>
</div>
and my javascript legacy code looks like
$('#dyncontent').load('/showviewcontent');
I added in the dynamic content, some angular directive and binding instruction
my angular code is like this
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function ($scope) {
.....
});
How to make the binding / angular directive works on the newly added content?
You need to manually start the angular module using angular.bootstrap
$('#dyncontent').load('/showviewcontent', function() {
angular.bootstrap(document.getElementById('dyncontent'), ['myApp']);
});
I'm trying to add two angular apps / modules to one page.
In the fiddles below you can see that always only the first module, referenced in the html code, will work correctly, whereas the second is not recognized by angular.
In this fiddle we can only execute the doSearch2 method, whereas in this fiddle only the doSearch method works correctly.
I'm looking for the way how to correctly place two angular modules into one page.
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.

I created an alternative directive that doesn't have ngApp's limitations. It's called ngModule. This is what you code would look like when you use it:
<!DOCTYPE html>
<html>
<head>
<script src="angular.js"></script>
<script src="angular.ng-modules.js"></script>
<script>
var moduleA = angular.module("MyModuleA", []);
moduleA.controller("MyControllerA", function($scope) {
$scope.name = "Bob A";
});
var moduleB = angular.module("MyModuleB", []);
moduleB.controller("MyControllerB", function($scope) {
$scope.name = "Steve B";
});
</script>
</head>
<body>
<div ng-modules="MyModuleA, MyModuleB">
<h1>Module A, B</h1>
<div ng-controller="MyControllerA">
{{name}}
</div>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
<div ng-module="MyModuleB">
<h1>Just Module B</h1>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
</body>
</html>
You can get the source code at:
http://www.simplygoodcode.com/2014/04/angularjs-getting-around-ngapp-limitations-with-ngmodule/
It's essentially the same code used internally by AngularJS without the limitations.
Why do you want to use multiple [ng-app] ? Since Angular is resumed by using modules, you can use an app that use multiple dependencies.
Javascript:
// setter syntax -> initializing other module for demonstration
angular.module('otherModule', []);
angular.module('app', ['otherModule'])
.controller('AppController', function () {
// ...do something
});
// getter syntax
angular.module('otherModule')
.controller('OtherController', function () {
// ...do something
});
HTML:
<div ng-app="app">
<div ng-controller="AppController">...</div>
<div ng-controller="OtherController">...</div>
</div>
EDIT
Keep in mind that if you want to use controller inside controller you have to use the controllerAs syntax, like so:
<div ng-app="app">
<div ng-controller="AppController as app">
<div ng-controller="OtherController as other">...</div>
</div>
</div>
You can bootstrap multiple angular applications, but:
1) You need to manually bootstrap them
2) You should not use "document" as the root, but the node where the angular interface is contained to:
var todoRootNode = jQuery('[ng-controller=TodoController]');
angular.bootstrap(todoRootNode, ['TodoApp']);
This would be safe.
Manual bootstrapping both the modules will work. Look at this
<!-- IN HTML -->
<div id="dvFirst">
<div ng-controller="FirstController">
<p>1: {{ desc }}</p>
</div>
</div>
<div id="dvSecond">
<div ng-controller="SecondController ">
<p>2: {{ desc }}</p>
</div>
</div>
// IN SCRIPT
var dvFirst = document.getElementById('dvFirst');
var dvSecond = document.getElementById('dvSecond');
angular.element(document).ready(function() {
angular.bootstrap(dvFirst, ['firstApp']);
angular.bootstrap(dvSecond, ['secondApp']);
});

NOTE: In html, there is no ng-app. id has been used instead.
I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app.

Hope this will help
How do I make a jsfiddle out of the following code:
<html>
<head>
</head>
<body>
<div ng-app ng-controller="MainCtrl">
<ul>
<li ng-repeat="num in nums">
{{num}}
</li>
</ul>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.4/angular.js"></script>
<script type="text/javascript" charset="utf-8">
function MainCtrl($scope) {
$scope.nums = ["1","2"];
}
</script>
</body>
</html>
My non working attempt: http://jsfiddle.net/zhon/3DHjg/ shows nothing and has errors.
You need to set some things up in jsFiddle for this to work.
First, on the left panel, under "Frameworks & Extensions", select "No wrap - in <body>".
Now, under "Fiddle Options", change "Body tag" to <body ng-app='myApp'>
In the JS panel, initiate your module:
var app = angular.module('myApp', []);
Check it out: http://jsfiddle.net/VSph2/1/
#pkozlowski.opensource has a nice blog post about how to use jsFiddle to write AngularJS sample programs.
You've defined your controller in a function scope that is not accessible to angular (angular is not yet loaded). In other words you are trying to call angular library's functions and helpers like below example before getting angular library loaded.
function onload(){
function MainCtrl(){}
}
To resolve this, switch your angular load type to be No wrap - in <body> like shown in screenshot.
here is a working example in jsfiddle
Click JAVASCRIPT button, choose angular version and place where u want include loaded script:
Then click HTML button and add ng-app in body tag. Its all:)
I am writing my answer for those who land on this page , I was used to use ng-module directive but in jsfiddle after half an hour I realized that ng-module is not allowed and you see no error , and when changed that ng-module to ng-app fiddle worked very well .I just wanted to share this .And no wrap (body) is required too.
<div ng-app="appX" ng-controller="appCtrl">
<p>{{greeting}}
</p>
</div>
var app=angular.module("appX",[]);
console.log(app);
app.controller("appCtrl",function($scope){
$scope.greeting="Hello World";
});
https://jsfiddle.net/cloudnine/trgrjwf1/7/
Since Angular 1.4.8 has been chosen by JSFiddle as the top option for Angular V1 in its JAVASCRIPT setting panel, more restriction applies: both ng-app and ng-controller should be declared in HTML to make it work.
Sample HTML:
<div ng-app="myApp" ng-controller="myCtrl">
<input type="text" ng-model="sample" placeholder="type something here...">
<span>{{sample}}</span>
</div>
Sample JS:
angular.module('myApp', [])
.controller('myCtrl', function($scope) {});
