【问题描述】:
我想在事件处理程序中使用突变。我的事件是这样定义的:
(JSX attribute) onOk?: ((e: React.MouseEvent<any, MouseEvent>) => void) | undefined
这就是我从客户端调用突变的方式
export const IMPORT_INFO_MUTATION = gql`
mutation ImportPolicy($data: ImportPolicyInput!) {
importPolicy(data:$data)
{
_id
name
}
}
最终我这样称呼它:
onOk={() => {
useImportPolicyMutation({
variables: {
data: {
jsonData: JSON.parse(importPolicyData)
}
},
})
}
`不要担心突变中的变量和参数。他们很好。问题是我收到以下错误:
Unhandled Rejection (Invariant Violation): Invalid hook call. Hooks can only
be called inside of the body of a function component. This could happen for
one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
这是一个钩子,因为 useMutation 是这样定义的:
return ReactApolloHooks.useMutation<ImportPolicyMutation, ImportPolicyMutationVariables>(
ImportPolicyDocument,
baseOptions
)
那么,如何在事件处理程序中调用突变?
