[英]React redux submit and use data form submited in the next page
我正在使用 redux-form 並且在提交時我試圖將提交的數據傳遞到另一個頁面,在那里我應該使用提交的 redux-form 數據來構建其他東西。 我對 redux 領域很陌生,但我試圖了解減速器和動作創建器的工作原理。 在這一點上,我正在將提交的數據付諸行動,並且在 reducer 中,有效負載是未定義的。 那么我怎樣才能有正確的提交表單流程->調度一個動作->將數據傳遞到reducer->將數據獲取到下一頁。
這是我的 redux 形式:
<form method="POST" action="/" autoComplete="off" noValidate onSubmit={handleSubmit(handleSubmitData)}>
{initialFields.map((key, index) => {
return (
<Field key={index} label={key} name={key} component={renderTextField} />
);
})}
<Button type="submit" disabled={submitting} size="small" variant="contained" color="primary"> Submit </Button> {/* onClick={submitting ? submitting : reset } */}
<Button type="button" disabled={pristine || submitting} size="small" onClick={reset} variant="contained" color="secondary"> Clear Values </Button>
</form>
出口:
function mapStateToProps({ form }) {
return form;
}
export default connect(mapStateToProps)(reduxForm({
form: "swimForm",
validate,
asyncValidate,
})(SwimForm));
行動:
export const getSwimFormValues = (props) => async dispatch => {
console.log("From Action",props)
dispatch({
type: SUBMIT_SWIM_FORM,
payload: props.values
});
};
和減速機:
const initialState = {
values: []
};
export default function(state = initialState, action) {
switch (action.type) {
case SUBMIT_SWIM_FORM:
console.log("From Reducer", action,)
return {
...state,
values: payload
};
default:
return state;
}
}
首先,確保將payload
更改為action.payload
否則它將始終未定義。 然后你 map state 到道具的部分創建一個 object 像這樣:
const mapStateToProps = state => {
// make sure that the name of the property with form values is actually `form`
// you can log the state and see what exactly you need to assign
console.log(state);
return {
form: state.form,
}
};
