Assuming you are actually using Cordova, check FileEntry, which has methods named moveToand copyTo.
假设您实际上使用的是 Cordova，请检查FileEntry，它具有名为moveTo和 的方法copyTo。
Be aware that the file systems API are a callback hell.
请注意，文件系统 API 是回调地狱。
One quick example from the docs cooked overlooking the docs:
一个来自煮熟的文档的快速示例，可以俯瞰文档：
var fail = function(err) { console.log(err) }
window.resolveLocalFileSystemURI("file:///example.txt", function(file) {
window.resolveLocalFileSystemURI("file:///directory-to-move-to", function(destination) {
file.moveTo(destination,"example.txt");
},fail)
},fail);
I skipped the error handling functions for clearness, suppose it works without it.
为了清楚起见，我跳过了错误处理函数，假设没有它也能工作。
