代码

function SavePic(file){ 
     var d = new Date();
     var n = d.getTime();
     //new file name
     var newFileName = n + ".jpg";

     currentDir.getFile(newFileName,{create: true,exclusive:false},function gotFileEntry(fileEntry){
         var path = fileEntry.fullPath.replace(newFileName,"");
         fileEntry.remove();
         var fileTransfer = new FileTransfer();
         fileTransfer.download(file, path+""+fileName,function(theFile){

             alert("File Downloaded Successfully");
         },function(error){
               alert("File Download Failed"+ error.code);
           });
     },fail);
}
