    WhWidgetSendButton.init(host, proto, options);

好像您在声明变量$this->db->trans_start(); $this->db->query('AN SQL QUERY...'); $this->db->query('ANOTHER QUERY...'); //This raises an error $this->db->trans_complete(); //A rollback is done, and should cancel the first query，但从未设置它。

本质上是WhWidgetSendButton，然后您试图在未定义的变量上调用WhWidgetSendButton = undefined。

在致电.init(host, proto, options)之前，您需要将init设置为WhWidgetSendButton之类。

即使声明变量为尖角声明var xyz，也仍未定义错误
