在react中渲染嵌套的对象数组

我映射了多个对象。 [{name:"y", country:"US", cities:[obj,obj,ob]},{name:"y",

country:"US", cities:[obj,obj,ob]}]

我如何嵌套一个循环,以便首先遍历对象,然后遍历(在此示例中)城市?谢谢!

我的没有嵌套外观的渲染函数如下所示:

render() {

const persons = this.state.name.map((item, i) => {

return (

<div>

<h5> {item.name} </h5>

<h5> {item.country} </h5>

//here I would like to show the cities

</div>

);

});

return (

<div>

<div className = "panel-list">

All: {persons}

</div>

</div>

);

}

城市对象示例:

[{visitors:34, rating:4}, 

{visitors:1234, rating:1},

{visitors:124, rating:2}]

回答:

您可以使用嵌套映射来映射内部子对象以及

     render() {

const persons = this.state.name.map((item, i) => {

return (

<div>

<h5> {item.name} </h5>

<h5> {item.country} </h5>

<h4>{item.cities.map((city) => {

return (<li>{/* city object details here*/}</li>)

})}</h4>

</div>);

});

return (

<div>

<div className = "panel-list">

All: {persons}

</div>

</div>

);

}
