本文实现自定义路由,主要是事件hashchange的使用,然后根据我们的业务需求封装。
首先实现一个router的类,并实例化。
function _router(config){ this.config = config "htmlcode">var Router = router({ '/' : function(){content.style.backgroundColor = 'white';}, '/1': function(){content.style.backgroundColor = 'blue';}, '/2': function(){content.style.backgroundColor = 'green';} })方法二:
Router.route('/3',function(){ content.style.backgroundColor = 'yellow'; })
完整代码:
<html> <head> <title></title> </head> <body> <ul> <li><a href="#/1">/1: blue</a></li> <li><a href="#/2">/2: green</a></li> <li><a href="#/3">/3: yellow</a></li> </ul> <script> var content = document.querySelector('body'); function _router(config){ this.config = config ? config : {}; } _router.prototype = { event:function(str,callback){ var events = str.split(' '); for (var i in events) window.addEventListener(events[i],callback,false); }, init: function() { this.event('load hashchange',this.refresh.bind(this)); return this; }, refresh: function() { this.currentUrl = location.hash.slice(1) || '/'; this.config[this.currentUrl](); }, route: function(path,callback){ this.config[path] = callback || function(){}; } } function router (config){ return new _router(config).init(); } var Router = router({ '/' : function(){content.style.backgroundColor = 'white';}, '/1': function(){content.style.backgroundColor = 'blue';}, '/2': function(){content.style.backgroundColor = 'green';} }) Router.route('/3',function(){ content.style.backgroundColor = 'yellow'; }) </script> </body> </html> <script> </script>以上就是本文的全部内容,希望本文的内容对大家的学习或者工作能带来一定的帮助,同时也希望多多支持!
