[英]Using browser javascript, how to get the contents of the files and subfolders of the user-specified local directory
可能是特定于 Google-Chrome 的答案...我找到了 https://github.com/GoogleChromeLabs/browser-nativefs 。 这有一个链接https://browser-nativefs.glitch.me/ 。 查看源代码并下载 html、css 和 mjs 文件。
我修改了 script.mjs 如下(仅共享代码的修改部分,并带有注释以指示确切的修改):
Array.prototype.asyncForEach = async function (fn) {
for (let i = 0; i < this.length; i++) {
await fn(this[i], i);
}
};
openDirectoryButton.addEventListener('click', async () => {
try {
const blobs = await directoryOpen({ recursive: true });
alert('upload of folder is done')
//const blobs = await directoryOpen();
let fileStructure = '';
await/*added this 'await'*/ blobs.sort((a, b) => {
a = a.webkitRelativePath + a.name;
b = b.webkitRelativePath + b.name;
if (a < b) {
return -1;
} else if (a > b) {
return 1;
}
return 0;
}).asyncForEach/*changed this forEach to asyncForEach*/(async (blob) => {
// The Native File System API currently reports the `webkitRelativePath`
// as empty string `''`.
//added print out of file blob content
fileStructure += `${blob.webkitRelativePath}${
blob.webkitRelativePath.endsWith(blob.name) ?
'' : blob.name}, content: ${await blob.text()}\n`;
});
