我开始通过观看一些教程和文档来学习 React.js。一些我在 Google Chrome 上遇到这个问题的原因:
在 Firefox 中，它不显示任何内容，应该显示代码中的信息。

JavaScript
var Note = React.createClass({
edit: function() {
alert('editing note');
},
remove: function() {
alert('removing note');
},
render: function() {
return (
<div className="note">
<span>

});
React.render(<Note>Hello World</Note>,
document.getElementById('react-container'));

div.note:active {

div.note p {

padding: 5px;
font-family: "Shadows Into Light", Arial;
}
div.note:hover > span {
opacity: 1;
}
div.note > span {
position: absolute;
bottom: 2px;
right: 2px;
opacity: 0;
transition: opacity .25s linear;
}
div.note button {
margin: 2px;
}
div.note > textarea {
height: 75%;
background: rgba(255, 255, 255, .5);
}
.glyphicon-plus {
position: fixed;
top: 10px;
right: 10px;
}
我不明白为什么我在两个浏览器中都缺少信息。该信息应该会出现，因为这是教程代码的一部分。
最佳答案
这是一个跨源问题。您可能正在尝试使用 file://或 C:\从本地驱动器加载 Note.js。要使用跨源请求，您需要在计算机上安装 Web 服务器。查看 express.js 和此示例，了解如何在您的计算机上设置简单的 node.js Web 服务器:https://expressjs.com/en/starter/hello-world.html
