本文介绍了在React中循环遍历对象的简单数组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我没有使用JSX.这有问题吗?这被认为是不好的做法吗?
I am not using JSX. Is this a problem? Is this considered bad practice?
var links = [
{ endpoint: '/america' },
{ endpoint: '/canada' },
{ endpoint: '/norway' },
{ endpoint: '/bahamas' }
];
class Navigation extends React.Component {
render() {
return (
<div className="navigation">
<ul>
const listItems = links.map((link) =>
<li key={link.endpoint}>{link.endpoint}</li>
);
</ul>
</div>
);
}
基于react docs的基本列表组件部分,看来我应该能够打印数组的内容,就像我在< ul></ul>内一样;
Based on the basic list component section of the react docs, it seems like I should be able to print the contents of an array, the way I'm doing it inside my <ul></ul>

问题是我正在使用对象数组吗?该文档正在使用一个简单的数组.我希望朝正确的方向前进.
Is the problem that I am using an array of objects? The docs are using a simple array. I'd appreciate a push into the right direction.
推荐答案
问题是您的语法无效,您应该输入以下内容:
The issue is that your syntax is invalid, you should have something like this :
var links = [
{ endpoint: '/america' },
{ endpoint: '/canada' },
{ endpoint: '/norway' },
{ endpoint: '/bahamas' }
];
class Navigation extends React.Component {
render() {
const listItems = links.map((link) =>
<li key={link.endpoint}>{link.endpoint}</li>
);
return (
<div className="navigation">
<ul>
{listItems}
</ul>
</div>
);
}
