Question

所以我试图在已经存在的项目constructor中添加命令以检索英雄联盟玩家的信息，我在npm上使用InsomBot来查找，对此软件包进行的唯一修改是更新API URL，因为它们已过时且不正确，我的代码在下面，调试器中的问题图像也在下面，一旦程序到达第105行，它就会跳转因为我似乎没有理由错过第111行，或许我在这里错过了一个简单的缩进错误，或者我没有正确地关闭某些内容，等等。任何帮助都将不胜感激。

第105行= api.summonerByName（term，＆＃39; na＆＃39;，function（results）{ 第111行= var defIndex = message.indexOf（def）;

Answer 1

第111行包含第105行之后的下一个语句，因此它非常有意义。

api.summonerByName()是一种异步方法，因此只有在有结果可用时才会调用其回调（第106和107行），但程序的其余部分将继续运行。

nodejs，函数无缘无故地跳转到完全不相关的行？
