context is not defined

非常抱歉,我的回答中有误。在使用 `context.emit` 时,需要将 `context` 作为参数传入 `setup` 函数中。以下是正确的示例代码:
```js
import { defineComponent } from 'vue'
export default defineComponent({
setup(props, { emit }) {
const handleClick = () => {
emit('my-event', 'some data')
}
return {
handleClick
}
}
})
```
在这个例子中,我们将 `context.emit` 改为了 `{ emit }`,并在函数中直接调用 `emit` 函数来触发事件。同时,我们也将 `context` 改为了 `{ emit }`,以便在函数中可以直接使用 `emit` 函数。

apifox前置脚本错误 :context is not defined
这是因为在前置脚本中使用了`context`变量,但该变量未被定义。请确认是否在前置脚本中正确地定义了`context`变量,并确保该变量在当前作用域中可用。
另外,也请注意前置脚本中的语法错误或其他逻辑错误,这些问题也可能导致该错误的出现。建议您逐行检查前置脚本并排除问题。如果无法解决问题,可以提供更多的代码和上下文信息以便于更好地理解问题。
