微信小程序之在线答题(2)

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:
