我正在尝试在 React/Redux 中创建一个表单。现在我只希望表单在提交表单时触发我的函数 handleSubmit。但是目前看起来该功能在页面加载时立即触发......

export default class AssetsAdd extends React.Component {

  componentDidMount() {
    console.log(this)
  }

  handleSubmit(event) {
    if (this.refs.titleInput !== '') {
      event.preventDefault();
      var asset = {
        date: '',
        title : this.refs.titleInput.value,
        id : '',
        type: this.refs.typeInput.value
      }

      return this.props.dispatch(addAsset(asset))
    }


  }

  render() {
    return (
      <div>
        <Row>
          <Portlet title='New Asset' form>
            <Form horizontal onSubmit={this.handleSubmit}>
              <FormGroup>
                <Label text='Title' size='3' />
                <Input ref="titleInput" placeholder='Enter asset title' size='4'/>
              </FormGroup>
              <FormGroup>
                <Label text='Type' size='3' />
                <Input ref="typeInput" placeholder='Enter asset type' size='4'/>
              </FormGroup>
              <FormGroup>
                <Label text='Description' size='3' />
                <Input ref="descriptionInput" placeholder='Enter asset description' size='4'/>
              </FormGroup>
              <FormGroup>
                <Label text='Documentation' size='3' />
                <Input ref="documentationInput" placeholder='Enter documentation URL' size='4'/>
              </FormGroup>
              <FormActionBar>
                <SubmitButton value='Submit'/>
                <CancelButton value='Cancel'/>
              </FormActionBar>
            </Form>
          </Portlet>
        </Row>
      </div>
    )
  }
}

function mapStateToProps(state) {
  return {
    assets: state.assets
  };
}

export const AssetAddContainer = connect(mapStateToProps)(AssetsAdd);

我知道其余的代码还不完全正确，但我现在主要关心的是在正确的时刻触发 onSubmit 操作。

提前致谢！
