推荐答案

这是一个包含名为<的属性的JavaScript对象code> on ，它又包含属于函数的属性。



要调用其中一个函数，你可以像这个：

This is a JavaScript object containing a property called on, which in turn contains properties which are functions.

To invoke one of the functions you would write it like this:

configuration.on.start(transactionId, arguments)
