Question

我有多行事件所以让它们成为单行事件我有逻辑以下但是当我们连接数组并将值推到results时它会抛出错误，任何想法我怎么能解决这个问题或正确的解决方案加入到数组的对象？

ctrl.js

 fs.readdir(dir,function(err, files){
            if (err) { throw err; }
               logFile = getNewestFile(files, dir)
               console.log(logFile);
            var items = [];
            var item = [];
            var readStream = fs.createReadStream(dir + '/' + logFile,'utf8');
                  readStream.pipe(split()).on('data', function (line) {
                      if (regex.test(line)) {
                          item = [];
                          items.push(item);
                      }
                      item.push(line);
                    var lines = items.map(function (item) {
                        return item.join(' ');
                    });
                    lines.forEach(function(line){
                      results.push({value:line});
                    });
                  });
              readStream.on('end',function(){
                var slicedArray = results.slice(Math.max(results.length - 200, 1));
                cb(null,slicedArray);
                results = [];
              });
        });
