Lag*_*hen 11 javascript reactjs
我正在尝试阅读和写作，File System Web API但我不断发现TypeError Uncaught (in promise) TypeError: window.showOpenFilePicker is not a function，我不知道发生了什么。
这是反应代码片段：
const FileReader = () => {
const openThisFile = async () => {
const [fileHandle] = await window.showOpenFilePicker(); // error: Property 'showOpenFilePicker' does not exist on type 'Window & typeof globalThis'
console.log(fileHandle);
};
return (
<div>
<button onClick={openThisFile}>Open file</button>
</div>
);
};
export default FileReader;
所以我认为它在 React 中不起作用，然后我尝试了 Vanilla Javascript，但我仍然不断进入TypeError Uncaught (in promise) TypeError: window.showOpenFilePicker is not a function控制台。这是代码片段。

let fileHandle;
async function getFile() {
[fileHandle] = await window.showOpenFilePicker(pickerOpts);
// run code with our fileHandle
}
console.log(fileHandle);
</script>
</body>
</html>
知道我做错了什么吗？
