I am using a combination of the initialize() function together with change event listeners to update derived attributes. The idea is first to compute the attributes on model initialization, and second to let the model listen to its own changes and update the attributes accordingly. My solution looks roughly like this: MyModel: Backbone.Model.extend({ initialize: function() … Read more
In Ember.js (version 1.0.0rc3) this can be accomplished by using the Ember.js location API: App.Router.reopen({ location: ‘history’ }); And then setting the web server to redirect traffic to the Ember application. To give a concrete example here is a basic Apache .htaccess file redirecting traffic to the Ember application located in index.html: RewriteEngine on RewriteCond … Read more
Use the not selector. Example: $(‘.collapsiblock’).click(function(){ $(‘.collapsiblock’).not(this).each(function(){ $(this).slideUp(); }); $(this).slideDown(); })
Yes, you can use jQuery’s attribute selector for that. var linksToGoogle = $(‘a[href=”https://google.com”]’); Alternatively, if your interest is rather links starting with a certain URL, use the attribute-starts-with selector: var allLinksToGoogle = $(‘a[href^=”https://google.com”]’);
There is no cross-browser way to do this. Internet Explorer supports the following: navigator.browserLanguage: browser language navigator.systemLanguage: Windows system language navigator.userLanguage: Windows user-specific language But there is no way to access these settings from any other browsers (that I can tell) so don’t use them: stick to the standard navigator.language (corresponding to the browser language) … Read more

As an example I’m going with a search-page with products being shown. Products can be paged, filtered, sorted. Of course this is … Read more
The angular.forEach loop can’t break on a condition match. My personal advice is to use a NATIVE FOR loop instead of angular.forEach. The NATIVE FOR loop is around 90% faster then other for loops. USE FOR loop IN ANGULAR: var numbers = [0, 1, 2, 3, 4, 5]; for (var i = 0, len = … Read more
Probably you haven’t injected $http service to your controller. There are several ways of doing that. Please read this reference about DI. Then it gets very simple: function MyController($scope, $http) { // … your code }
You could use ng-init in an outer div: <div ng-init=”param=’value’;”> <div ng-controller=”BasketController” > <label>param: {{value}}</label> </div> </div> The parameter will then be available in your controller’s scope: function BasketController($scope) { console.log($scope.param); }
You can simplify this by checking the first object that is returned from JQuery like so: if ($(“.mydivclass”)[0]){ // Do something if class exists } else { // Do something if class does not exist } In this case if there is a truthy value at the first ([0]) index, then assume class exists.
