# Tour of Heroes: the vision
|
||
# 《英雄之旅》目标概览
|
||
|
||
Our grand plan is to build an app to help a staffing agency manage its stable of heroes.
|
||
Even heroes need to find work.
|
||
|
||
我们的终极计划是构建一个程序，来帮助员工管理英雄们的马厩。即使英雄们也需要找工作。
|
||
|
||
Of course we'll only make a little progress in this tutorial. What we do build will
|
||
have many of the features we expect to find in a full-blown, data-driven application: acquiring and displaying
|
||
a list of heroes, editing a selected hero's detail, and navigating among different
|
||
views of heroic data.
|
||
|
||
当然，我们在这个教程中，我们只完成一小步。我们这次构建的应用将用到很多对特性：获得并显示英雄列表，编辑所选英雄的详情，并在英雄数据的多个视图之间建立导航。这些特性，在全面、数据驱动的应用中经常见到。
|
||
|
||
The Tour of Heroes covers the core fundamentals of Angular.
|
||
We’ll use built-in directives to show/hide elements and display lists of hero data.
|
||
We’ll create a component to display hero details and another to show an array of heroes.
|
||
We'll use one-way data binding for read-only data. We'll add editable fields to update a model
|
||
with two-way data binding. We'll bind component methods to user events like key strokes and clicks.
|
||
We’ll learn to select a hero from a master list and edit that hero in the details view. We'll
|
||
format data with pipes. We'll create a shared service to assemble our heroes. And we'll use routing to navigate among different views and their components.
|
||
|
||
这篇《英雄之旅》覆盖了Angular的核心原则。
|
||
我们将使用内建指令来显示/隐藏元素，并且显示英雄数据的列表。
|
||
我们将创建一个组件来显示英雄的详情，另一个组件则用来显示英雄列表。
|
||
我们将对只读数据使用单向数据绑定。我们将添加一些可编辑字段，并使用双向数据绑定更新模型。
|
||
我们将把组件上的方法绑定到用户事件上，比如按键和点击。
|
||
我们将学习从主列表视图中选择一个英雄，然后在详情视图中编辑它。
|
||
我们将通过管道对数据进行格式化。
|
||
我们将创建一个共享服务来管理我们的英雄们。
|
||
我们将使用路由在不同的视图及其组件之间进行导航。
|
||
|
||
We’ll learn enough core Angular to get started and gain confidence that
|
||
Angular can do whatever we need it to do.
|
||
We'll be covering a lot of ground at an introductory level but we’ll find plenty of links
|
||
to chapters with greater depth.
|
||
|
||
我们将学习足够的Angular核心技术，以尝试起步，并建立信心 —— Angular确实能做到我们需要它做的这些。
|
||
我们将覆盖大部分“简介级”知识，但是我们还会找到大量的链接，指向更深的章节。

## The End Game

## 终极游戏
|

|
||
Here's a visual idea of where we're going in this tour, beginning with the "Dashboard"
|
||
view and our most heroic heroes:
|
||
|
||
在这个教程中，还有一些可视化思想。放一个“黑板报（Dashboard）”视图，来展示我们最勇敢的英雄。
|
||
|
||

|
||
img(src='/resources/images/devguide/toh/heroes-dashboard-1.png' alt="英雄黑板报的输出")
|
||
|
||
:marked
|
||
Above the dashboard are two links ("Dashboard" and "Heroes").
|
||
We could click them to navigate between this Dashboard and a Heroes view.
|
||
|
||
这个仪表盘中有两个链接：“黑板报”和“英雄”。
|
||
我们将点它们来在“黑板报”和“英雄”视图之间导航。
|
||
|
||
Instead we click the dashboard hero named "Magneta" and the router takes us to a "Hero Details" view
|
||
of that hero where we can change the hero's name.
|
||
|
||
当我们点击黑板报上名叫“Magneta”的英雄时，路由将把我们带到这个英雄的详情页，在这里，我们可以修改英雄的名字。
|
||
|
||
figure.image-display
|
||
img(src='/resources/images/devguide/toh/hero-details-1.png' alt="英雄详情的输出")
|
||
|
||
:marked
|
||
Clicking the "Back" button would return us to the "Dashboard".
|
||
Links at the top can take us to either of the main views.
|
||
We'll click "Heroes". The app takes to the "Heroes" master list view.
|
||
|
||
点击“后退（Back）”按钮将把我们带回“黑板报”。
|
||
顶部的链接可以把我们带到任何一个主视图。
|
||
如果我们点击“英雄”链接，本应用将把我们带到“英雄”列表主视图。
|
||
|
||
figure.image-display
|
||
img(src='/resources/images/devguide/toh/heroes-list-2.png' alt="英雄列表的输出")
|
||
|
||
:marked
|
||
We click a different hero and the readonly mini-detail beneath the list reflects our new choice.
|
||
|
||
当我们点击另一位英雄时，一个只读的“微型视图”会显示在列表下方，以反应我们的选择。
|
||
|
||
We click the "View Details" button to drill into the
|
||
editable details of our selected hero.
|
||
|
||
我们可以点击其中的“查看详情”按钮来进入所选英雄的“编辑视图”。
|
||
|
||
The following diagram captures all of our navigation options.
|
||
|
||
下列图标汇总了我们的所有可选导航路径。

## Up Next
|
||
## 接下来
|
||
|
||
We’ll build this Tour of Heroes together, step by step.
|
||
We'll motivate each step with a requirement that we've
|
||
met in countless applications. Everything has a reason.
|
||
|
||
我们将共同一步步的构建出《英雄之旅》。
|
||
我们将通过与无数应用中类似的需求，驱动我们走向下一步。任何事，都会有理由。
|
||
|
||
And we’ll meet many of the core fundamentals of Angular along the way.
|
||
|
||
这一路，我们将遇到Angular的大量核心原则。
