其实框架就是让你使用起来简单些

关于路由其实用一个轻便的框架就可以了

路由就是根据url后面的路径不同变换代码

前端路由由于其特殊性最常见表述为这样的形式

# !/contact/me

    1. index    1. # whoop    1. /about    1. /contact    1. /contact/me    1. /not-found

然后我们直接上page.js使用代码

    page.base('');    page('/', index);    page('/index', index);    page('/about', about);    page('/contact', contact);    page('/contact/:contactName', contact);    page({        hashbang:true    });    function index() {    }    function about() {    }    function contact(ctx) {    }

page.js 可以使你使用hashbang

现在我们开始写组件

avalon2 组件写法

定义组件

avalon.component('ms-approute', {    template: '',    defaults: {    },    soleSlot: 'page'});

使用组件

    index    about    contact

 function deepFind(obj, path) {    var paths = path.split('.')            , current = obj            , i;    for (i = 0; i < paths.length; ++i) {        if (current[paths[i]] == undefined) {            return undefined;        } else {            current = current[paths[i]];        }    }    return current;}var Approute = function (options) {    var lastRoute = '';    var lastRouteEle = {};    var ele = {};    function check(route) {        var length = ele.target.children.length;        for (var i = 0; i < length; i++) {            (function (index) {                var page = ele.target.children.item(index);                if (page.dataset.route == route) {                    lastRoute = route;                    lastRouteEle = page;                    page.setAttribute("selected", "");                }            })(i);        }    }    function emit(newValue, oldValue) {        lastRouteEle.removeAttribute("selected");        check(newValue);    }    return {        emit: emit,        config: {            onInit: function (a) {                console.log("onInit!!");            },            onReady: function (a) {                console.log("onReady!!");                var self = this;                ele = a;                var route = deepFind(self, options.path);                check(route);            },            onViewChange: function (a) {                console.log("onViewChange!!");            },            onDispose: function (a) {                console.log("onDispose!!")            }        }    }};var approute = new Approute({    path: "route"});var con = function () {    return {        $id: "test",        route: "index",        approuteconfig: approute.config    }};var vm = avalon.define(con());vm.$watch("route", function (newValue, oldValue) {    approute.emit(newValue, oldValue);});
