here is my django rendered test page
<!doctype html>
<html lang="en">
<head>
</head>
<body>
<div id="todo">
</div>
<script type="text/template" id="item-template">
<div>
<input id="todo_complete" type="checkbox" <%= completed ? 'checked="checked"' : '' %>>
<%- title %>
</div>
</script>
<script src="jquery.js"></script>
<script src="underscore.js"></script>
<script src="backbone.js"></script>
<script src="app.js"></script>
//the app.js is my backbone app
<script >
var foo_models = new fooCollection({{django_rendered_json_vaiable}})
//this is how I get backbone collection initial data
</script>
</body>
</html>
the above code is what I get so far, I get the backbone bootstrapped models as foo_models,
but this variable can't be access in my app.js file, then I found this question, which use AMD approach,but my app is fairly small,all I need is get the initial data in another js file,so I don't want to add require.js and I don't want to make this foo_models variable global。
so how can I do that?
* EDITED *
Just change these lines:
<script src="app.js"></script>
//the app.js is my backbone app
<script >
var foo_models = new fooCollection({{django_rendered_json_vaiable}})
//this is how I get backbone collection initial data
</script>
to:
<script >
var raw_foo_models = {{django_rendered_json_vaiable}};
</script>
<script src="app.js"></script>
Then, add this line:
var foo_models = new fooCollection(raw_foo_models);
somewhere in your app (after fooCollection has been defined).

I have just started working on Angularjs and facing a problem in calling the factory defined in other module. Actually I need to clean the code so I have to build all the functionalities in one js file and I have to use them in my main js file where I have defined my controllers. I have made a simple code to understand the problem. Thanks in advance
Following is the Html file:-
<!DOCTYPE html>
<html>
<head>
<script data-require="angular.js#1.1.5" data-semver="1.1.5" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="function.js"></script>
<script src="script.js"></script>
</head>
<body ng-app="MyServiceModuleOne">
<div ng-controller="TestController">
<button type="button" ng-click="getFn()"> Test </button>
</div>
</body>
</html>
Following is script.js file
var myModule= angular.module('MyServiceModuleTwo',['MyServiceModuleOne']);
myModule.controller('TestController', ['$scope', 'notify', function($scope, notify){
$scope.getFn = function() {
notify.sampleFun();
}
}]);
Following is function.js file:-
var myModule = angular.module('MyServiceModuleOne', []);
myModule.factory('notify', function() {
return {
sampleFun: function() {
alert('hi');
}
};
});
There are couple of changes needed.
You are referencing MyServiceModuleOne as root module, but the controller you are referencing is in MyServiceModuleTwo.
So change your ng-app from MyServiceModuleOne to MyServiceModuleTwo.
I've updated the plnkr
I am trying to implement Collapsable Tree in d3.
I have a code like the following in my .ejs file.
<div class="space5px" >
<%= startNode %>
<%= console.log(treeData) %>
</div>
<div id="tree-container"></div>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="http://d3js.org/d3.v3.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var treeData = treeData;
...
I can see the name value on the console but treeData becomes undefined in script part (at var treeData = treeData).
Do you have any ideas?
Problem is solved by using JSON.stringify(treeData) and then JSON.parse('<%- treeData %>'). Do not waste your time!
Pretty simple test app, but for some reason, the template is not rendering and so far I just try one template only. Only blank page showing. no error

You actually don't append the View's el to DOM. You don't even call the view instance's render method. You could do it on initialization, i.e. in your initialize method or after creating the instance.
var mainView = new app.AppMainView();
mainView.render();
mainView.$el.appendTo(document.body);
Edit: I just noticed that you are passing a selector to the view (el: '#nested-viewer'). This means that just need to call the render method as the element exists in the DOM.
I am brand new to marionette and am following along with a textbook to build a simple app using marionette. I ran into this problem almost immediately, they telly you to put a console.log() in a function, except it doesn't show up in my browser when i run it. Here's the script below:
<script type="text/javascript">
var ContactManager = new Marionette.Application();
ContactManager.on("initialize:after", function(){
console.log("ContactManager has started!");
});
ContactManager.start();
</script>
And here's the whole HTML file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Marionette Contact Manager</title>
<link href="./assets/css/bootstrap.css" rel="stylesheet">
<link href="./assets/css/application.css" rel="stylesheet">
</head>
<body>
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<span class="brand">Contact manager</span>
</div>
</div>
</div>
<div class="container">
<p>Here is static content in the web page. You'll notice that it gets 21 replaced by our app as soon as we start it.</p>
</div>
<script src="./assets/js/vendor/jquery.js"></script>
<script src="./assets/js/vendor/json2.js"></script>
<script src="./assets/js/vendor/underscore.js"></script>
<script src="./assets/js/vendor/backbone.js"></script>
<script src="./assets/js/vendor/backbone.marionette.js"></script>
<script type="text/javascript">
var ContactManager = new Marionette.Application();
ContactManager.on("initialize:after", function(){
console.log("ContactManager has started!");
});
ContactManager.start();
</script>
</body>
</html>
Any help would be greatly appreciated, I can do a console.log() outside of the ContactManager.on() code and it will work. Any ideas?
So i figured out the answer to my own question with a little research. Marionette has updated "initialize:after" to "start". For a full list of updates you can check here -->

I am trying to show a message in console using backbone js. Here is what I have tried:
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<title>Backbone</title>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

<script>
var Router = Backbone.Router.extend({
routes: {
'' : 'home'
}
});
var router = new Router();
router.on('route:home', function () {
console.log('rout is loaded');
});
Backbone.history.start();
</script>
</body>
</html>
After trying this I am getting this error below:
Uncaught ReferenceError: jQuery is not defined on jquery.is.min.js:10
Uncaught TypeError: Property '$' of object # is not a function on backbone.js 1388
Uncaught TypeError: Cannot call method 'create' of undefined on measureIt.js:120
Whats wrong with my router?
The link which you are using is not a valid jquery link. Try changing it.
//invalid link
http://cdnjs.cloudflare.com/ajax/libs/jquery.is.js/0.2.1/jquery.is.min.js
Correct link
http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min.js
Seem like you're currently missing the core jQuery file. Try to include it.
