#quiz4guo

这个web应用采用的技术:

• flask
• bootstrap
• sqlite
• jQuery & ajax

####核心代码段

#####5种页面 共制作了5种页面，为选择题，填空题，判断题，结分页（当前这个页面），添加题目页面

• 填空题用的是表单提交
• 选择和判断用的ajax方式

一个缺陷 单选题过渡到判断题时 页面重写不干净，出现['\u56e0', '\u4e3a', '\u6240', '\u4ee5']这样的js代码漏到页面上的问题

原因大概是ajax返回内容以document.write方式写到页面的奇怪副作用，无力解决，太邪门了。

bootstrap自适应，可以自动据终端屏幕大小调整页面，但结分页的分数栏用了自适应就消失了，所以结分页这句 <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/> 去除了。
