或者您可以事先将它们变成数组：
return (
<div>
{ addressElement1() }
{ addressElement2() }
</div>
);
答案 1 :(得分：1)
嗯，你的实施有一些小错误。如果要渲染变量，则需要使用{address}。并且可以使用简单的[，]
组合React组件您的最终代码将是这样的
let address = [<addressElement1/>, <addressElement2/>]
return (
<div>
{address}
</div>
);
修改
let address = [<AddressElement1 key="left"/>, <AddressElement2 key="right"/>]
但是您必须重命名无状态组件宽度A而不是
如果您不想使用密钥，可以直接
return (
<div>
<AddressElement1/>
<AddressElement2/>
</div>
);
