JS实现简单路由器功能的方法

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。
