本文实例讲述了JS实现简单路由器功能的方法。分享给大家供大家参考。具体实现方法如下：

var wawa = {}; wawa.Router = function(){ function Router(){ } Router.prototype.setup = function(routemap, defaultFunc){ var that = this, rule, func; this.routemap = []; this.defaultFunc = defaultFunc; for (var rule in routemap) { if (!routemap.hasOwnProperty(rule)) continue; that.routemap.push({ rule: new RegExp(rule, 'i'), func: routemap[rule] }); } }; Router.prototype.start = function(){ console.log(window.location.hash); var hash = location.hash, route, matchResult; for (var routeIndex in this.routemap){ route = this.routemap[routeIndex]; matchResult = hash.match(route.rule); if (matchResult){ route.func.apply(window, matchResult.slice(1)); return; } } this.defaultFunc(); }; return Router; }(); var router = new wawa.Router(); router.setup({ '#/list/(.*)/(.*)': function(cate, id){ console.log('list', cate, id); }, '#/show/(.*)': function(id){ console.log('show', id); } }, function(){ console.log('default router'); }); router.start();

希望本文所述对大家的javascript程序设计有所帮助。
