在React中渲染对象属性

Question

我有一个像这样的对象

export const otherInformation = [
{
    "FAQ": ['Getting started guide', 'Selling policy'],
    "Help & Support": ['Help guide', 'Selling policy'],
    "Legal": ['Terms of Use', 'Privacy Policy']
}]

我的代码

class Information extends Component {
    render() {
        const otherInformationLoop = otherInformation.map((value, key) => {
            return (
                <div>
                    <div className="col-md-4" key={key}>
                        <div className="dashboard-info">

                            {Object.keys(value).map((val, k) => {
                                return (<h4 k={k}>{val}</h4>)
                                })
                            }

                        </div>
                    </div>
                </div>
            )
        })

        return (
            { otherInformationLoop }
            // <div></div>
        );
    }
}

我无法循环遍历该对象.

获得的错误是这样的

Information.render(): A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object

如何循环对象以获得获得的结果

提前致谢.任何帮助表示赞赏

您正在渲染一个数组,但是您只能从您的react组件返回一个块,将您的map函数包装在div中

class Information extends Component {
    render() {
        const otherInformationLoop = otherInformation.map((value, key) => {
            return (
                <div>
                    <div className="col-md-4" key={key}>
                        <div className="dashboard-info">

                            {Object.keys(value).map((val, k) => {
                                return (<h4 k={k}>{val}</h4>)
                                })
                            }

                        </div>
                    </div>
                </div>
            )
        })

        return (

            <div>{ otherInformationLoop }</div>
        );
    }
}
