推荐答案

没有条码扫描器事件 - 大多数条码扫描器充当键盘输入，但通常可以配置为提供前导和尾随序列，以便您可以识别数据。究竟如何做到这一点因制造商和制造商甚至型号而异，因此您需要与扫描仪制造商交谈，或查看他们的网站。

There is no "barcode scanner" event - most barcode scanners act as a keyboard input, but can generally be configured to provide a leading and trailing sequence so you can identify the data. Exactly how this is done varies from manufacturer to manufacturer and even model to model, so you need to talk to the maker of your scanner, or check their website.
