使用Angular2开发,常会遇到路由重定向的应用场景. 路由重定向的配置办法是这样的: {path:'要定向的路径', redirectTo:'要定向到的目标路由'} 比如某组件有个路由插件,并且一进入该组件就想要路由插件加载出内容,我们的路由配置可能这么写: routes: Routes = [ { path:'', component:'ParentComponent', children:[ { path:'', redirectTo: 'page1' },//定向 { path:'pa

一.前言 就在上月,公司的一个同事建议当前的前端全面改用AngularJs进行开发,而我们采用的就是ASP.NET 5项目,原本我的计划是采用TypeScript直接进行Angular2开发.所以借用这段时间来写下如何在ASP.NET 5下搭建基于TypeScript的Angualr2的项目,下面我们就进入正题. 二.环境配置 如果读者直接按照Angular.io上的方式搭建是无法通过的,所以下面我们的教程基本跟Angular.io上的类似,只是其中的配置会有所不同,并且也会多出一些步骤. 1.

1.新建项目 2.新建Model public class TodoItem { public int Id { get; set; } public string Key { get; set; } public string Name { get; set; } public bool IsComplete { get; set; } public string Desc { get; set; } } 3.数据访问接口 public interface ITodoRepository {

首先,需要在VS2015环境下更新到update2,并安装asp.net core环境,并安装Node.js插件. 新建asp.net core项目: 此时,需要先新建npm配置文件,如图: 并定义node.js需要加载的文件: { "name": "angular2-quickstart", "version": "1.0.0", "scripts": { "tsc": "t

1.不同界面传参 <router-link :to="{path:'地址'},query:{name:val}">, 其它界面获取: this.$route.query.name 2.router重定向 router.redirect({ "*":"/index" }) 3.刷新当前路由 <router-link :to="{path:'地址'},query:{name:val}" @click.native

第一步:安装 cnpm install vue-router --save 路由配置基本语法 router下index.js引入 import Vue from "vue"; import Router from "vue-router"; import HelloWorld from "@/components/HelloWorld"; 按需引入 底下会写到懒加载路由 export default new Router({ routers: [

Ionic2使用了近似原生App的页面导航方式,并不支持Angular2的路由.这种方式在开发本地App的时候比较方便,但如果要用来开发纯Web页面就有点问题了,这种情况下Angular2的router可以提供更灵活的配置.比如在首页是一个Tabs页面的情况下,如何控制用户看到的第一项Tab?默认情况下都是会导航到第一个Tab,而且地址栏的URL并不会跟随页面的切换而变化.好在Ionic2提供了一种类似路由的DeepLinker功能,可以实现以上目的. DeepLinker与NavControl

angular2 组件 首先了解angular2 组件的含义 angular2的应用就是一系列组件的集合 我们需要创建可复用的组件供多个组件重复使用 组件是嵌套的,实际应用中组件是相互嵌套使用的 组件中的数据调用可以使用inputs和outputs 一个组件可以是一种指令 一个组件可以包含前端表现及后端逻辑 一个组件可以是一个代码片段,能够独立运行 进一步理解指令 一个指令就是一个组件 一个指令可以装饰指令,用于改变DOM 一个指令可以是模板指令,可以改变element 一个实际例子 一辆车有门

angularjs2 学习笔记(一) 开发环境搭建   开发环境,vs2013 update 5,win7 x64,目前最新angular2版本为beta 17 第一步:安装node.js 安装node.js(https://nodejs.org/en/),为的是能够使用npm获得angular2.0的开发包 验证是否安装成功 cmd下输入 node -v npm -v 第二步:在vs2013上安装typescript 安装完成后在项目中可以添加typescript项目了,并且在项目属性栏中会有

最近学习了 react-router v4,根据官方 API 文档和网上资源做了一个简单的路由示例. 先用官方的工具 create-react-app  初始化一个 react 项目模板,再根据自己的需要修改. 要实现的路由: 1. 登录页(/login) 2. 主页(/home):一级导航 3. 商品管理(/goods):一级导航 4. 商品列表(/goods/list):二级导航 5. 商品品牌(/goods/brand):二级导航 6. 路由重定向: (1)未登录时,地址栏输入主域名(lo

Angular2以组件化的视角来看待web应用,使用Angular2开发的web应用,就是一棵组件树.组件大致分为两类:一类是如list.table这种通放之四海而皆准的通用组件,一类是专为业务开发的业务组件.实际开发中大部分时间我们都需要处理业务组件.对于SPA应用来说,一个通用的问题就是如何控制页面的切换,解决这个问题的通用方法就是利用路由器来实现. 路由配置 现在我们先撇开Angular2来看看通用的路由器模型.通常来讲SPA应用需要路由配置信息: [ { path: '', pathMa

路由设置 Angular中路由的配置应该按照先具体路由到通用路由的设置,因为Angular使用先匹配者优先的原则. 示例: 路由设置如下: export const reportRoute: Routes = [ { path: 'report', children: [ { path: '', component: ReportComponent },{ path: ':id', component: ReportDetailComponent },{ path: 'report-new',
