  plus.io.resolveLocalFileSystemURL( fileURL, function( fs ) {  

    // 可通过fs进行文件操作   

    if (fs.isDirectory) {  

      const directoryReader = fs.createReader();  

      directoryReader.readEntries((entries) => {  

        for(let i=0;i<entries.length;i++){  

          const entry = entries[i];  

          console.log([entry.name](http://entry.name))  

          if(entry.isFile&&nameModel.test([entry.name](http://entry.name))){  

            files.push(entry)  

            console.log('get a XLSfile')  

          }  

        }  

        console.log(files.length)  

        // return files;  

      })  

    }
