How do hosted services like UserVoice embed their content on other web sites?

How do hosted services like UserVoice embed their content on other web sites? I see that it is via including a JavaScript file from the service provider on your own page, however, what I'm interested in are the building blocks for creating a service like that. For example, do they use a library like jQuery, mooTools, or prototypejs and how do they avoid namespace clashes? Also wondered if there were any books, articles, blog posts that go over this specific use of JavaScript (not looking for general resources on JavaScript). Regards and thanks in advance, Eliot Here is a great tutorial I found

I am very new in Angular 2 and I have the following question about services .

Tell ember.js to use different key for its model's “id”

阅读更多关于 Tell ember.js to use different key for its model's “id”

问题 I am stuck in a situation where I shouldn't return id field in the API endpoint. I need to tell ember to use slug field for / instead of id . I tried DS.RESTAdapter.map('App.Post', id: {key: 'slug'}) . While this works perfectly fine for App.Post.find("a-slug-name") , It messes up for App.Post.find() resulting in adding a new model every time it is called. And also assigning id to null. So how should I do this. 回答1: You need to specify the attribute that should be used as the primaryKey in

Angular JS views not updating properly

阅读更多关于 Angular JS views not updating properly

问题 I have the following action ng-click in my view -> which inturn calls a jQuery ajax function that displays jQuery Qtip -> In the Qtip popup I have an ng-click on an element -> which performs a $http post and has some callbacks to update $scope values . So all these things are happening properly. But the updates are not getting reflected in the view as per the changes made in the callback in the final stage. I have a function for "ng-mousemove" in my view. So whenever I move my mouse, the

阅读更多关于 Help learning from pivotaltracker's javascript, looking for a high level breakdown

问题 My javascript skills are fairly basic, I can work with jquery etc. but when it comes to building a site like pivotaltracker I wouldn't know where to begin! Was hoping someone could help break down their javascript architecture and explain at a high level how they went about designing their js frameowork to make a gmail like design where it is purely javascript driven (at least I think it is). Things like: layout wise, is there a single div container that loads the different panels? Does it

问题 I have a Backbone.js model that I'm trying to destroy when the user clicks a link in the model's view. The view is something like this (pseudocode because it's implemented in CoffeeScript which can be found at the bottom of the question). var window.ListingSaveView = Backbone.View.extend({ events: { 'click a.delete': 'onDestroy' }, onDestroy: function(event){ event.preventDefault(); this.model.destroy({ success: function(model, response){ console.log "Success"; }, error: function(model,

Which JavaScript-framework can search CSS stylesheet rules and edit their properties?

阅读更多关于 Which JavaScript-framework can search CSS stylesheet rules and edit their properties?

问题 The Question Which JavaScript framework (prototype, script.aculo.us, Mootools, MochiKit...) has decent CSS rule editing support? This is about changing a style rule. I want to have dynamic CSS classes which change. Example: <style> #answer, .reveal { display: none; color: blue; } #answer { /* additional stuff */ } </style> Now, via JavaScript, I want to change the rule that has the “display: none” in it. – I’m convinced that sometimes this is the right way to go; I’m not looking for
