You need to configure the inspections in Settings/Editor/Inspections, then in the list on the right, find JavaScript/JavaScript validity issues. That worked for me to remove the Chai warnings. (I am using the WebStorm 11 EAP at the moment.)
今天写代码的时候,有一个类的数据始终不能插入,老是提示在You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'describe, picPath1, picPath2, picPath3, picPath4, picPath5, agentId, belongStore' at line 1。因为用的是SSH进行插入,所以SQL语句不用自己写,检查了每个字段也没写错。
