微信小程序异步API同步化研究

Research on Synchronization of WeChat Applet Asynchronous API

分析微信小程序异步API的特点,针对其在某些应用场景下不适用的情况,给出一种高效、通用的解决方案,实现在调用异步方式获取的关键变量之前,检查、等待、确保变量有意义的同步操作。

Analyzes the characteristics of WeChat applet asynchronous API, and gives an efficient and universal solution for the case that it is not ap-plicable in some application scenarios, implements checking, before calling the key variables obtained in asynchronous mode, waiting for, ensuring that the variables have meaningful synchronization operations.
