试试这个代码：

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); 
      } 
     ); 
    }
