我重构了我的代码，现在有一个无状态组件从容器组件传递一个数组。然后我尝试映射传递到我的无状态组件的数组，但无法将其渲染。
正在正确传递数组，但是当我Sub Copy_Distribution()
Dim OriginSheet As Worksheet
Set OriginSheet = Sheets("Import Setup")
Dim ObjectiveSheet As Worksheet
Set ObjectiveSheet = Sheets("Import")
Dim ColumnToPaste As Long
Dim RowToGetValue As Long
Dim GetColumn As Long
ColumnToPaste = 15 'Because GetColumn
For RowToGetValue = 3 To 98 'From 3 to 98 right?
If OriginSheet.Cells(RowToGetValue, 12).Value > 0 Then
For GetColumn = 1 To 4
ObjectiveSheet.Cells(2, ColumnToPaste + GetColumn).Value = OriginSheet.Cells(RowToGetValue, 11 + GetColumn).Value
Next GetColumn
ColumnToPaste = ColumnToPaste + 4
End If
Next RowToGetValue
End Sub
时，它只显示第一个console.log(msg)并且没有任何内容被渲染。
有人能发现下面的代码有什么问题吗？
msg然后我有一个class App extends Component {
componentDidMount() {
const { getData } = this.props;
getData();
}
render() {
const { messages } = this.props;
return (
<ul>
<MessageList messages={messages} />
</ul>
);
}
}
const mapStateToProps = state => {
return {
messages: state.messages ? state.messages : [],
members: state.members ? state.members : []
};
};
const mapDispatchToProps = dispatch => {
return bindActionCreators({ getChatLog, getMembersData }, dispatch);
};
export default connect(mapStateToProps, mapDispatchToProps)(App);
无状态组件，看起来像这样。
MessageList
