I'm having trouble getting a simple App example to route. I'm using the backbone-on-rails gem.
Here's my App.js.coffee:
window.App =
Models: {}
Collections: {}
Views: {}
Routers: {}
$(document).ready ->
MyRouter = Backbone.Router.extend(
routes:
'' : 'index'
index: ->
console.log("Inside router")
new App.Views.HomeIndex()
)
router = new MyRouter
Backbone.history.start
console.log(router.routes[Backbone.history.fragment])
The router never reaches the index callback and the View is never rendered.
Here's the HTML Page that is rendered by Rails:
<!DOCTYPE html>
<html>
<head>
<title>App</title>
<link href="/assets/application.css?body=1" media="screen" rel="stylesheet" />
<script src="/assets/jquery.js?body=1"></script>
<script src="/assets/jquery_ujs.js?body=1"></script>
<script src="/assets/underscore.js?body=1"></script>

<script src="/assets/routers/homes_router.js?body=1"></script>
<script src="/assets/routers/homes_routers.js?body=1"></script>
<script src="/assets/application.js?body=1"></script>

</head>
<body>
<div id="app"></div>
</body>
</html>
What do I need to do to properly instantiate a Backbone Router and get it to route to my Views?
Looks like you just need to call Backbone.history.start rather than simply reference it. This just references the function:
Backbone.history.start
This calls it:
Backbone.history.start()
The function-calling parentheses are only optional when you supply some arguments.

I am using Plunker to produce my React Example.
The React Libraries are included by "Find and external libraries" provided by Plunker.

In the console, It throws the below exception

However, This example works if I tried another react libraries such as that provided by unpkg.com.

In your code type="text/jsx" is missing. Add type="text/jsx" to your script as <script type="text/jsx" src="script.jsx"></script> and try. And use umd build for development. See the working code below

cjs(commonjs2): User will use this format in a build tool, it excludes all modules in node_modules folder from bundled files.
umd: User will use this format directly in browser, all 3rd-party packages will be bundled within.
i am trying to use ng-admin for the firs time. i am just following the example in and i am unable to see anything in the browser. my code is minimal, so not sure what i am doing wrong.
any ideas? did i not install correctly? i just downloaded it from a site and unzipped the file.

</head>
<body ng-app="myApp" ng-strict-di>
<div ui-view="ng-admin"></div>
</body>
</html>
// declare a new module called 'myApp', and make it require the `ng-admin` module as a dependency
var myApp = angular.module('myApp', ['ng-admin']);
// declare a function to run when the module bootstraps (during the 'config' phase)
myApp.config(['NgAdminConfigurationProvider', function (nga) {
// create an admin application
var admin = nga.application('My First Admin')
.baseApiUrl("http://vl-esifakis-ice:8000/tracker/");
var foundry = nga.entity('foundry');
foundry.listView().fields([
nga.field('name'),
nga.field('id')
]);
admin.addEntity(foundry);
// more configuration here later
// ...
// attach the admin application to the DOM and execute it
nga.configure(admin);
}]);
Here is a demo which i have made,

Hello guys for 2 days i am trying to call a react component from html and every time it throw me that error "Error: Cannot find react component MyReact"
so that is my html.I would be very grateful if someone help me

<!--data-toggle="modal" data-target="#{{myprops.id}}"-->
</body>
</html>
that is tutorial file:
var MyReact = React.createClass({
render: function() {
console.log("qweqw");
return(
<div>
<h2>georgi</h2>
</div>
);
}
});
app.value('MyReact',MyReact);
and my config file:
var app = angular.module('listOfDiaries', ['react','ngMaterial','ngMessages']);
app.controller('myCtrl', ["$scope", "myFirstService", function ($scope, myFirstService) {
var self = this;
//and directive and so on..
I don't program Angular; but looking at the code in the app.directive statement; if that code is run immediately MyReact is not defined. Try switch the MyReact class and the app.directive block.
I'm trying to build up a REST client written in AngularJS that uses $resources for consuming the REST service and ng-grid library for the User Interface.
By using just the $resource module dependency my code works, however if I introduce also the ngGrid dependency it just displays an empty div.
I've little experience with modules but the syntax seems correct....
<link rel="stylesheet" type="text/css" href="ng-grid.css" />
<link rel="stylesheet" type="text/css" href="style.css" />
<script type="text/javascript" src="jquery-1.9.1.js"></script>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="ng-grid-2.0.7.min.js"></script>
<script type="text/javascript" src="angular-resource.js"></script>
<script language="javascript">
angular.module('myApp',['ngResource'], ['ngGrid']);
function Ctrl($scope,$resource) {
var restservice = $resource(
'http://host/myapp/json', {
}, {
query: { method: 'GET', isArray: true }
}
);
$scope.gridOptions = restservice.query();
};
</script>
</head>
<body>
<div ng-app="myApp">
<div ng-controller="Ctrl">
<div class="gridStyle" ng-grid="gridOptions"></div>
</div>
</div>
</body>
Do you see any error in the above code ?
Thanks!
You don't need to pass in a separate array for each module, nest them under one array like this.
angular.module('myApp',['ngResource', 'ngGrid']);
I am having issues trying to show a partial html on my index.html file (Nothing is displayed).
Please see my index.html code:
<!doctype html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>My AngularJS App</title>
<link rel="stylesheet" href="css/app.css"/>
<link rel="stylesheet" href="css/animations.css"/>
<link rel="stylesheet" href="css/bootstrap.css"/>
<script src="js/jquery-1.11.0.min.js"></script>
<script src="lib/angular/angular.js"></script>
<script src="lib/angular/angular-animate.js"></script>
<script src="lib/angular/angular-route.js"></script>
<script src="lib/angular/angular-resource.js"></script>
<script src="js/app.js"></script>
<script src="js/animations.js"></script>
<script src="js/services.js"></script>
<script src="js/controllers.js"></script>
<script src="js/filters.js"></script>
<script src="js/directives.js"></script>
</head>
<body>
<li>
Show People
</li>
<div ng-view></div>
</body>
</html>
Then I try to load people.html that is on partials directory, using routing on app.js:
'use strict';
// Declare app level module which depends on filters, and services
var myApp = angular.module('myApp', ['ngRoute', 'filters', 'services', 'directives', 'controllers']);
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.when('/people', {
templateUrl : 'patials/people.html',
controller : 'PeopleController'
}).otherwise({
redirectTo : '/people'
});
}]);
If I replace the ng-view part on my index.html with my template file content, everything displays fine, so I dont think I have an issue on my controller declarations.
Can you take a look and help me figuring out what's wrong?
Thanks!
You are using var myApp = angular.module('myApp', []); inside your controller. If you add an array as a second parameter in angular.module, the module is automatically created as a new one and overrides the previous one with the same name, so the config is not working anymore, because in your code it is defined on a different module.
Just change the code in the PeopleController definition from
var myApp = angular.module('myApp', []);
to
var myApp = angular.module('myApp');
and it should work
