从函数返回JSX不会产生任何问题

Question

来自Return JSX from function

的跟进

我有一个组件需要检查多个选项并根据这些选项返回。因此，我创建了一个在我的组件返回语句中调用的外部函数，以确定将返回的格式：

render() {
    const { policy } = this.props;
    let deployment = policy.Deployment;
    let value = policy.value;
    let policyLegend = deployment.policyLegend;
    let policyObj = this.valueToPolicy(policyLegend, value);
    console.log(policyObj);
    if(policy.name == "SP4") {
      policyLegend[1].values = this.formatSp4Firmware(policyLegend[1]);
      return (
        <div>
          <Form onSubmit={ (event) => this.handleSubmit(event, this.props) }>
            {
              policyLegend.map((policy) => {
                return (
                  <div key={ policy.id }>
                    <h3>{ policy.displayName }</h3>
                    { this.renderSp4Policies(policy) }
                  </div>
                );
              })
            }
            <Button name={ 'Submit' } type='submit'>Submit</Button>
            <Button onClick={ this.props.onCancel }>Cancel</Button>
          </Form>
        </div>
      )
    } 
  }

renderSp4Policies(policy) {
    if(policy.displayName == "Firmware Options") {
      let firmwareDropdownNames = this.formatFirmawareDropdownNames(policy);
      let toggles = policy.values[0][Object.keys(policy.values[0])];
      let toggleOptions = []
      Object.keys(toggles).map(toggle => {
      	if(typeof(toggles[toggle]) == "boolean"){
          var obj = {};
          obj[toggle] = toggles[toggle];
      		toggleOptions.push(obj);
        }
      })
      return (
        toggleOptions.map(toggleOption => {
          let toggleName = Object.keys(toggleOption).toString();
          return (
            <Form.Field key={ toggleName }>
              <label>{ toggleName }</label>
              <Checkbox toggle />
            </Form.Field>
          )
        })
      )
    } else {
        return (
          policy.values.map(value => {
            return(
              <Form.Field key={ value.name }>
                <label>{ value.displayName || value.name }</label>
                <Checkbox toggle />
              </Form.Field>
            )
          }
        )
      )
    }
  }

我已经应用了上一篇文章给出的一些答案，取得了一定的成功。

在renderSp4Policies else语句中显示的内容，但原始if(policy.displayName == "Firmware Options")不返回任何内容。

感谢所有建议，提前谢谢！
