director.js实现前端路由
注:director.js的官网 https://github.com/flatiron/director
director.js是什么?
理解:前端的route框架,director.js客户端的路由注册/解析器,在不刷新的情况下,利用“#”号组织不同的URL路径,并根据不同的URL路径进行不同的方法调用。意思就是有什么样的路径就有什么样的方法。
场合:客户端浏览器和node.js的服务器应用。非常适合用来开发不需要刷新的单页面应用程序以及node.js应用。
兼容性:不依赖与任何库。例如jquery等。但它又和jquery能很好的融合在一起;
客户端的路由:
客户端的路由 (也称为哈希路由) 允许您指定一些关于使用URL应用状态的信息,当用户指定固定的URL,进行相应的页面显示。
简单例子
1. 单独使用
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>A Gentle Introduction</title> <script src="https://rawgit.com/flatiron/director/master/build/director.min.js"> </script> <script> var author = function () { console.log("author"); }; var books = function () { console.log("books"); }; var viewBook = function (bookId) { console.log("viewBook: bookId is populated: " + bookId); }; var routes = { '/author': author, '/books': [books, function() { console.log("An inline route handler."); }], '/books/view/:bookId': viewBook }; var router = Router(routes); router.init(); </script> </head> <body> <ul> <li><a href="#/author">#/author</a></li> <li><a href="#/books">#/books</a></li> <li><a href="#/books/view/1">#/books/view/1</a></li> </ul> </body> </html>
2当与jquery相结合
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>A Gentle Introduction 2</title> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"> </script> <script src="https://rawgit.com/flatiron/director/master/build/director.min.js"> </script> <script> $('document').ready(function() { // // create some functions to be executed when // the correct route is issued by the user. // var showAuthorInfo = function () { console.log("showAuthorInfo"); }; var listBooks = function () { console.log("listBooks"); }; var allroutes = function() { var route = window.location.hash.slice(2); var sections = $('section'); var section; section = sections.filter('[data-route=' + route + ']'); if (section.length) { sections.hide(250); section.show(250); } }; // // define the routing table. // var routes = { '/author': showAuthorInfo, '/books': listBooks }; // // instantiate the router. // var router = Router(routes); // // a global configuration setting. // router.configure({ on: allroutes }); router.init(); }); </script> </head> <body> <section data-route="author">Author Name</section> <section data-route="books">Book1, Book2, Book3</section> <ul> <li><a href="#/author">#/author</a></li> <li><a href="#/books">#/books</a></li> </ul> </body> </html>
