我是 Vue 的新手，正在尝试处理表单。我正在制作一个 Web 应用程序来管理会议，为此我有一个多步骤表单来处理访客和主持人数据。当我单击提交按钮时，出现以下错误：- TypeError: Object(...) is not a function 。我在stackoverflow上搜索了它，但没有得到太多线索。以下是我的代码：-

问题是您在
createMeeting方法中调用scheduleMeeting--- ，或者更准确地说，您实际上并没有导入函数，而是导入了包含该函数的对象。您从
meeting.js导出这是导出您在
import语句中分配给scheduleMeeting的对象。因此，您的函数实际上位于代码中的
scheduleMeeting.scheduleMeeting处。以这种方式导出对象有点不寻常 - 默认导出与为 commonjs 导出设置
export.modules对象不太一样。我建议你遵循更 ES6 的方法：将
meeting.js更改为和你的进口声明
当然，还有其他方法可以构建它来修复它，但我认为这是最清楚的。
