我在react项目中使用react-codemirror2。我想添加一些功能，如自动括号关闭和自动标记关闭。有一个名为@codemirror/closebacks的npm包，但我找不到任何文档。
<ControlledEditor
onBeforeChange={handleChange}
value={value}
className="code-mirror-wrapper"
options={{
linerWrapping: true,
lint: true,
mode: language,
theme: 'material',
lineNumbers: true
}}
/>
这是我的反应成分。指定是否有一种方法可以在不使用@codemirror/closebackets等附加程序包的情况下进行操作。
您可以将autoCloseBrackets: true添加到选项中，它会正常工作。来自文档：
定义一个选项autoCloseBrackets，该选项将自动关闭括号和键入时使用引号。
import 'codemirror/addon/edit/closebrackets'
// other parts of the code//
<ControlledEditor
onBeforeChange={handleChange}
value={value}
className="code-mirror-wrapper"
options={{
linerWrapping: true,
lint: true,
mode: language,
theme: 'material',
lineNumbers: true,
autoCloseBrackets: true,
}}
/>
This really works:
