昨天是七夕,祝大家都过的快乐,希望这句迟到的问候不会造成大家心中的困扰。这一节讲到了前端比较重要的模块,性能以及调试异常模块。一个应用的性能往往是最核心的部分,就像人身体的各个器官一样,一小部分也不能马虎,否则你得到的只是你想象不到的苦果。在这里,我们封装了性能采集,调试输出、变量打印,以及异常收集。希望大家会对这方面有所了解与进步。

SIMPLE
ax::trace 输出信息
ax::var 变量输出,学习过PHP的应该知道有一个函数叫var_dump
总结
该模块封装了客户端应用的评估模块,即整个客户端的效率采集器,以及常用的调试方法。看似很多东西,其实也没有太过复杂的,输出调试借用了tracewin这个调试工具,大家可以网上找一下,用到的是windows的SendMessage接口。性能模块,封装了和异常有关的一些方法,那么我们下一节就开始讲解异常收集模块。
