Question

我们公司的客户需要特定的条形码校验和。我想出了以下内容，允许用户输入经销商部件号，部件号和序列号。现在，当您单击“保存”时，它将使用校验和正确计算条形码。现在，我们已经添加了一个数量框，以便我们可以打印x个条形码，序列号递增1.（即第一个序列号是000001，接下来是000002，依此类推）。我上周试图做的是更改此代码，以便用户可以输入部件号和sn，它将计算每个条形码到数量。这就是我们想要的： If user enters part numbers, first serial number and quantity then clicks "Save" this should be the result. At present, this can only be achieved by entering each serial number and clicking save

*注意：虽然可以输入数量，但我的代码中尚未使用实际值...

因此，要实现这一点，我需要找到一种方法来增加序列号而不会丢弃前导零但保持qty.length的长度。我还需要弄清楚如何使用部件号循环每个新的序列号，以获得条形码的正确校验和。经过一周的盯着这个，我希望一些新鲜和有经验的眼睛可以提供帮助。这是我的代码。
