我正在使用Redux-Form，并且正在尝试在用户单击提交时获取表单值。

这些是外形道具。如您所见，有提交功能：

  • 提交
  • 提交成功
  • 提交失败

onSubmitSucess并且onSubmitFail永远不会被调用。onSubmit被调用但没有参数。

我想要的只是获取表单值，以便我可以将它们发布到 API。

我怎样才能做到这一点？

AutoFormInternal.js

class AutoFormInternal extends Component {

    render() {

        let {
            componentFactory,
            fields,
            fieldMetadata,
            layout,
            handleSubmit,
            submitting
        } = this.props;

        let model = this.props.values;
        let fieldMetadataEvaluated = metadataEvaluator.evaluate(fieldMetadata, model, '', fields);

        let groupComponent = componentFactory.buildGroupComponent({
            component: layout.component,
            layout: layout,
            fields: fieldMetadataEvaluated,
            componentFactory: componentFactory
        });

        return (
            <div className="meta-form">
                <form onSubmit={handleSubmit}>
                    { groupComponent }

您应该将 onSubmit 函数引用作为参数传递给表单的 handleSubmit 方法：<form onSubmit={handleSubmit(onSubmit)}>。请注意，此处未调用 onSubmit 函数引用，您将其作为表单提交的“回调”提供。

现在当表单提交时，它应该调用onSubmit函数，它应该有1个参数，整个表单的值作为一个对象。

class AutoFormInternal extends Component {

render() {

    let {
        componentFactory,
        fields,
        fieldMetadata,
        layout,
        handleSubmit,
        submitting,
        onSubmit // <-- You need to reference this function passed from the wrapper component in order to pass it to redux-form's provided handleSubmit function
    } = this.props;

    ... *snip* ...

    return (
        <div className="meta-form">
            <form onSubmit={handleSubmit(onSubmit)}> // <-- Here's where we pass onSubmit to redux-form's handleSubmit
                { groupComponent }
                <ButtonToolbar>
                    <Button type="submit" bsStyle="primary" disabled={submitting}>Submit</Button>
                    <Button disabled={submitting}>Cancel</Button>
                </ButtonToolbar>
            </form>
        </div>
    )
}
}

AutoFormInternal.propTypes = {
    fields: PropTypes.object.isRequired,
    handleSubmit: PropTypes.func.isRequired,
    onSubmit: PropTypes.func.isRequired,
    resetForm: PropTypes.func.isRequired,
    submitting: PropTypes.bool.isRequired,
    componentFactory: PropTypes.object.isRequired,
    entity: PropTypes.object.isRequired,
    layout: PropTypes.object
};

export default reduxForm({
    form: 'simple'
})(AutoFormInternal);`

... *snip* ...

return <AutoFormInternal
        fields={fields}
        fieldMetadata={fieldMetadata}
        entity={entity}
        layout={layout}
        validate={validate}
        componentFactory={componentFactory}
        onSubmit={(formValues) => console.log(formValues)} // <-- formValues should be now be populated when the form is submitted
        onSubmitSuccess={() => console.log('submit success')}
        onSubmitFail={() => console.log('submit fail')}
         />
