推荐答案
乍一看它看起来相当不错（除了可能 clearTotals （）和clearAddOns（）方法，这些方法在您发布的代码中不可见。
At first sight it looks reasonably good (except for maybe the clearTotals() and clearAddOns() methods, which are not visible in the code that you posted).
当您说"我无法让它工作"时，精确度是多少你看到的症状是什么？什么是不起作用的，它的行为与预期的不同？
When you say "I can't get it to work", what are the precise symptoms that you are seeing? What is the thing that doesn't work, and how does its behaviour differ from the expected one?
