single-page-application

问题 Is it necessary to use CSRF Protection when the application relies on stateless authentication (using something like HMAC)? Example: We\'ve got a single page app (otherwise we have to append the token on each link: <a href=\"...?token=xyz\">...</a> . The user authenticates himself using POST /auth . On successful authentication the server will return some token. The token will be stored via JavaScript in some variable inside the single page app. This token will be used to access restricted

问题 What is the difference in Angular 2 between the following snippets: <div [class.extra-sparkle]=\"isDelightful\"> <div [ngClass]=\"{\'extra-sparkle\': isDelightful}\"> 回答1: This is special Angular binding syntax <div [class.extra-sparkle]="isDelightful"> This is part of the Angular compiler and you can't build a custom binding variant following this binding style. The only supported are [class.xxx]="..." , [style.xxx]="..." , and [attr.xxx]="..." ngClass is a normal Angular directive like you

I have successfully set $locationProvider.html5Mode(true); And all links from the landing page (index.html) work fine. The problem is, if partial urls are referenced directly, I get a 404, naturally, since the server endpoint definitions aren\'t coupled to client side-defined routes. So without

问题 I have a single page web application using angularJS. I need to print a div of certain page. I tried the following: The page contains few div (print.html) <div> <div> Do not print </div> <div id=\"printable\"> Print this div </div> <button ng-click=\"printDiv(\'printableArea\');\">Print Div</button> </div> The controller has following script: $scope.printDiv = function(divName) { var printContents = document.getElementById(divName).innerHTML; var originalContents = document.body.innerHTML;

问题 I\'ve been working on how to make a SPA crawlable by google based on google\'s instructions. Even though there are quite a few general explanations I couldn\'t find anywhere a more thorough step-by-step tutorial with actual examples. After having finished this I would like to share my solution so that others may also make use of it and possibly improve it further. I am using MVC with Webapi controllers, and Phantomjs on the server side, and Durandal on the client side with push-state enabled;

问题 I realize this is a basic question but I had no luck finding the answer elsewhere. Is store.dispatch synchronous or asynchronous in Redux ? In case it is asynchronous is there a possibility to add a callback after the action has been propagated as it is possible with React ? 回答1: AFAIK, dispatching action is synchronous.

问题 When building SPA style applications using frameworks like Angular, Ember, React, etc. what do people believe to be some best practices for authentication and session management? I can think of a couple of ways of considering approaching the problem.

问题 How do you definitively detect whether or not the user has pressed the back button in the browser? How do you enforce the use of an in-page back button inside a single page web application using a #URL system? Why on earth don\'t browser back buttons fire their own events!? 回答1: (Note: As per Sharky's feedback, I've included code to detect backspaces) So, I've seen these questions frequently on SO, and have recently run into the issue of controlling back button functionality myself. After a

问题 I\'m just learning JSF 2 thanks to this site I had learned a lot in such a short time. My question is regarding how to implement a common layout to all my JSF 2 pages and have only the content part of the page refresh not the whole page whenever I click a link/menu from a different panel.
