试试这段代码：

document.addEventListener("deviceready", onDeviceReady, false);

    function onDeviceReady() {
        console.log("device is ready");
        window.requestFileSystem  = window.requestFileSystem || window.webkitRequestFileSystem;
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
    }

    function fail() {
        console.log("failed to get filesystem");
    }

    function gotFS(fileSystem) {
        console.log("got filesystem");

            // save the file system for later access
        console.log(fileSystem.root.fullPath);
        window.rootFS = fileSystem.root;
    }

    function downloadImage(url, fileName){
        var ft = new FileTransfer();
        ft.download(
            url,
            window.rootFS.fullPath + "/" + fileName,
            function(entry) {
                console.log("download complete: " + entry.fullPath);

            },
            function(error) {
                console.log("download error" + error.code);
            }
        );
    }
