錯誤節點JS擷取記錄從MySQL數據庫

途徑：錯誤節點JS擷取記錄從MySQL數據庫

exports.authenticate = function(req, res) { 

    //connection.connect(); 
    var sql="SELECT * from users where username='"+req.body.user+"' and password='"+req.body.pass+"' LIMIT 1"; 
    connection.query(sql, function(err, rows, fields) { 
     if (err) throw err; 

     //res.send('Your data is: ', rows); 
     var str="Hi, <b>"+rows[0].name+"</b> ("+rows[0].email+")"; 

     sql="SELECT username,name from users ORDER BY name"; 
     connection.query(sql, function(err, datarows, fields) { 
      if (err) throw err; 
      //res.send('Your data is: ', rows+' <br/> All Users are : ', datarows.length+"<a href='/'>Login</a>"); 
      console.log(datarows); 
      res.render('home.jade', {title: 'Home',result:datarows}); 
      /*---------------The above calling jade-----------------*/ 
     }); 

     //str+="<a href='/'>Login</a>"; 
     //res.send(str); 
     //connection.end(); 
    });

玉：

extends layout 

block content 
    //p #{result} 
    -var list=[ { username: 'rohankumar1524', name: 'Rohan Kumar' }] 
    each item, i in result 
     p test #{item.length} 
     each role,j in item 
      p #{role}

輸出

test 

rohankumar1524 

Rohan Kumar

異常輸出

function (parser, fieldPackets, typeCast, nestTables, connection) { var self = this; var next = function() { return self._typeCast(fieldPacket, parser, connection.config.timezone, connection.config.supportBigNumbers); }; for (var i = 0; i < fieldPackets.length; i++) { var fieldPacket = fieldPackets[i]; var value; if (typeof typeCast == "function") { value = typeCast.apply(connection, [ new Field({ packet: fieldPacket, parser: parser }), next ]); } else { value = (typeCast) ? this._typeCast(fieldPacket, parser, connection.config.timezone, connection.config.supportBigNumbers) : ((fieldPacket.charsetNr === Charsets.BINARY) ? parser.parseLengthCodedBuffer() : parser.parseLengthCodedString()); } if (typeof nestTables == "string" && nestTables.length) { this[fieldPacket.table + nestTables + fieldPacket.name] = value; } else if (nestTables) { this[fieldPacket.table] = this[fieldPacket.table] || {}; this[fieldPacket.table][fieldPacket.name] = value; } else { this[fieldPacket.name] = value; } } }

另外這款

function (field, parser, timeZone, supportBigNumbers) { switch (field.type) { case Types.TIMESTAMP: case Types.DATE: case Types.DATETIME: case Types.NEWDATE: var dateString = parser.parseLengthCodedString(); if (dateString === null) { return null; } if (timeZone != 'local') { if (field.type === Types.DATE) { dateString += ' 00:00:00 ' + timeZone; } else { dateString += timeZone; } } return new Date(dateString); case Types.TINY: case Types.SHORT: case Types.LONG: case Types.INT24: case Types.YEAR: case Types.FLOAT: case Types.DOUBLE: case Types.LONGLONG: case Types.NEWDECIMAL: var numberString = parser.parseLengthCodedString(); return (numberString === null || (field.zeroFill && numberString[0] == "0")) ? numberString : ((supportBigNumbers && Number(numberString) > IEEE_754_BINARY_64_PRECISION) ? numberString : Number(numberString)); case Types.BIT: return parser.parseLengthCodedBuffer(); case Types.STRING: case Types.VAR_STRING: case Types.TINY_BLOB: case Types.MEDIUM_BLOB: case Types.LONG_BLOB: case Types.BLOB: return (field.charsetNr === Charsets.BINARY) ? parser.parseLengthCodedBuffer() : parser.parseLengthCodedString(); case Types.GEOMETRY: return parser.parseGeometryValue(); default: return parser.parseLengthCodedString(); } }

但是，當我在玉使用此代碼

extends layout 

block content 
    //p #{result} 
    -var list=[ { username: 'rohankumar1524', name: 'Rohan Kumar' }] 
    each item, i in list // list in place of result 
     p test #{item.length} 
     each role,j in item 
      p #{role}

的輸出爲

test 

rohankumar1524 

Rohan Kumar

預計

爲什麼出現這個問題，是任何其他module我有install通過npm

試試這個：

玉

extends layout 

block content 
    each item in result 
     p item.username 
     p item.name
