列表和其他类型的集合某种程度上也可以用组件来描述.
为了避免完全给列表新建一个单独的组件, 我们可以使用以下这种写法.
const SearchSuggestions = (props) => {
// renderSearchSuggestion() behaves as a pseudo SearchSuggestion component
// keep it self contained and it should be easy to extract later if needed
const renderSearchSuggestion = listItem => (
<li key={listItem.id}>{listItem.name} {listItem.id}</li>
);
return (
<ul>
{props.listItems.map(renderSearchSuggestion)}
</ul>
);
};
如果你想在更复杂的场景里面或者其他什么地方使用这个组件, 你能很轻松的复制这段代码到新的组件中. (不要过度设计组件)
If things get more complex or you want to use this component elsewhere,
you should be able to copy/paste the code out into a new component.
Don’t prematurely componentize.
