What is the shebang/hashbang for?

阅读更多关于 What is the shebang/hashbang for?

问题 Is there any other use for shebangs/hashbangs besides for making AJAX contents crawlable for Google? Or is that it? 回答1: The hash when used in a URL has existed since long before Ajax was invented. It was originally intended as a reference to a sub-section within a page. In this context, you would, for example, have a table of contents at the top of a page, each of which would be a hash link to a section of the same page. When you click on these links, the page scrolls down (or up) to the

Prevent user to leave the route in a single page app with hashbang

阅读更多关于 Prevent user to leave the route in a single page app with hashbang

问题 I am using Sammy.js for my single page app. I want to create functionality similar to SO (the one when you type your question and try to leave the page and it is asking you if you are sure). If it would not be a single page app, I would just do something like: $(window).bind('beforeunload', function(){ return 'Are you sure you want to leave?'; }); The problem is that in single page app user do not actually leave the page, but rather changing his document.location.hash (he can leave the page

pushState and SEO

问题 Many people have been saying, use pushState rather than hashbang. What I don't understand is, how would you be search-engine friendly without using hashbang? Presumably your pushState content is generated by client-side JavaScript code. The scenario is thusly: I'm on example.com . My user clicks a link: href="example.com/blog" pushState captures the click, updates the URL, grabs a JSON file from somewhere, and creates the listing of blog posts in the content area. With hashbangs, google knows

Removing #! from angular.js Urls in ASP.Net Web API

阅读更多关于 Removing #! from angular.js Urls in ASP.Net Web API

问题 So I am trying to remove the #! in my angular site and transition to html5. I've looked at other guides and I've implemented them with the locationProvider and base within the index file. The site works fine when you direct it through ng-href to a link but when I press refresh/directly input the url I get a 404 error. I was reading this has to do with the server side in which it does not know where to route when a 404 is hit since the .otherwise() is a hashbang function. That being said, I

Trigger audio stop in iframe when parent window navigates away (hashbang)

阅读更多关于 Trigger audio stop in iframe when parent window navigates away (hashbang)

问题 I have a web app in an iframe (Facebook Tab App) on a web page (Facebook). The web app plays audio and when the user navigates away, usually by clicking on another Facebook link, the page loads another Facebook page and the audio stops. This works on all browsers except Internet Explorer (IE9). Audio continues to play when I navigate to another Facebook page. Facebook seems to use the approach where many of their pages are displayed (using hashbang #! approach) without standard page reloading

问题 There are several advantages to the HTML5 Pushstate in comparison to hasbangs, in fact, Google is now encouraging the use of Pushstate. The only Pushstate disadvantage being publicly discussed is the fact that non-modern browsers do not support it. However, to me it seems that Pushstate is also disadvantageous when it comes to caching. I might be wrong, hence this question. is Pushstate inferior to Hashbangs when it comes to caching pages?

Empty URL hash causes page to jump on js events

阅读更多关于 Empty URL hash causes page to jump on js events

I have a gallery of photos with a next and previous button. If one of my javascript methods is broken for one reason or another when one of the buttons is clicked it will add a hash to the url i.e. www.google.com# . I know the hash can be given a div id to jump to that part of the page but when it's blank it jumps around my page a few times and I'm not sure what it's targeting. I thought of attempting to remove the hash from the url but then I'd have to ensure that on every action and that seems like bad practice. I would prefer if the hash just made no difference to the actions on the page.
