Tips:
前端进阶的概念一直比较模糊，我们往往以掌握知识的多少来划分初级中级和高级，但这并不全面，谁都不能保证自己掌握的知识是最全最好的，尤其在前端工程师这个职业，每天都是日新月异。
           

所以，我认为要分辨一个前端工程师的境界，除了掌握知识的多寡，还要掌握前端的思想，以及对知识的应用程度，评判的标准简单划分初级就是页面与页面之间的交互，中级是页面与数据之间的交互，高级就是数据与数据之间的交互，微信小程序的设计思想就是基于数据与数据之间的交互，我们操作更多的是数据，而非document。

下面讲解一下在线答题的思路，为什么那这个模块来说，因为这是一个比较简单、典型而且又实际应用的案例。

        原文：http://www.yealuo.com/WebArticle/Detail?KeyValue=A410D649-424E-4123-A0C5-FFC768F24FB2&ArticleType=zw

首先，我们通过数据接口拿到试卷的试题，渲染到页面上之后，就可以答题了，而答题的过程，其实是操作从接口拿到的数据，这样我们每次操作改变的都是数据而非页面。

然后在通过页面调整传参的形式，把做题结果的数据传递到下一个目标页面，进行需要的数据操作（筛选，计算，渲染）等。 整个做题的过程，都发生在前端，发生在接口数据上，只有在最后一步，保存做题结果的时候才与服务端交互。 这个案例很简单，也很典型，没什么难度，就是想记录一下这种思想，为了便于运行，我先用模拟数据代替接口数据，下面请看代码：
