獲得誤差函數做Ajax調用一次，我把這個變量

Question

出於某種原因，我不斷收到錯誤功能Ajax調用每當我把這個"ntaReqRef": ntaReqRef但是當我不包括它在我的Ajax調用完美的作品，所以我卡住至於它是否是非法的，還是它與我的代碼有關，因爲當我執行代碼時，它會在node.js中顯示正確的響應，但會提供一個錯誤函數。

function create(){ 
var samId = $('#samIda').val(); 
var itemDescrip = $('#itemDescrip').val(); 
var issueQty =$('#issuedQty').val(); 
var openQty = $('#openingQty').val(); 
var closeQty = $('#closingQty').val(); 
var corrupQty = $('#corruptedQty').val(); 
var remarks = $('#Remarks').val(); 
var ntaReqRef = $('#ntaReqRefa').val(); 
var postData = { 
       "samId": samId , "itemDescrip": itemDescrip, "issueQty" : 
       issueQty,"openQty" : openQty, "closeQty" :closeQty, 
       "corrupQty": corrupQty, "remarks": remarks, "ntaReqRef": 
       ntaReqRef 
       }; 
var postJSON = JSON.stringify(postData); 
$.ajax({ 
    url: "http://localhost:3000/api/insertRecord", // server url 
    type: "POST", //POST or GET 
    contentType: "application/json", // data to send in ajax format or querystring format 
    data: postJSON, 
    dataType : "json", //dataType is you telling jQuery what kind of 
    response to expect 
    success: function(response) { 
     alert('success'); 
     $("#Iresult").html("A record has been created. :D"); 
    }, 
    error: function(response) { 
     alert('error' + response); 
    } 
}); 
} 

我的關於變量有問題的html代碼。

<div class="field-wrap"> 
     <label> 
      NTA SAM Ref Number<span class="req">*</span> 
     </label> 
     <input type="NtaReqRef" id="ntaReqRefa" name= "ntaReqRef" required 
     autocomplete="off"/> 
     </div> 
     <input class="button" type="submit" id="insert" value="Create" 
     onclick="create()" /> 
     </form> 
     <div id= "Iresult"></div> 

這是我的服務器端代碼。

var MongoClient = require('mongodb').MongoClient; 
var url = 'mongodb://localhost:27017/myproject'; 
var insertDocument = function(db, req, callback) { 
db.collection('documents').insertOne({ 
//'_id': Object.keys(obj).length, 
    'samID': req.body.samId, 
    'itemDescription': req.body.itemDescrip, 
    'issuedQTY': req.body.issueQty, 
    'openingQTY':req.body.openQty, 
    'closingQTY':req.body.closeQty, 
    'corruptedQTY':req.body.corrupQty, 
    'Remarks':req.body.remarks, 
    'ntaSamRequestRef': req.body.ntaReqRef 
    //'Created Date': "<b>" + day + "/" + month + "/" + year + "</b>" 
}, function(err, results) { 
//assert.equal(err, null); 
    if(err) return callback(err); 
    console.log("Inserted a document into the documents collection."); 
    console.log(results); 
    var cursor = db.collection('documents').find({ 
     //'_id': Object.keys(obj).length, 
     'samID': req.body.samId 
    }).toArray(function(err, doc) { 
     if (err) { 
      return callback(err); 
     } else{ 
     console.log('Successfully queried'); 
     console.log(doc); 
     return callback(null, JSON.stringify(doc)); 
     } 
    }); 
}); 
}; 
module.exports = { 
postCollection : function(req,res){ 
    var samId = req.body.samId; 
    var itemDescrip = req.body.itemDescrip; 
    var issueQty = req.body.issueQty; 
    //var indexNo = Object.keys(obj).length; 
    var openQty = req.body.openQty; 
    var closeQty = req.body.closeQty; 
    var corrupQty = req.body.corrupQty; 
    var remarks = req.body.remarks; 
    var ntaReqRef = req.body.ntaReqRef; 
    //var createdDate = "<b>" + day + "/" + month + "/" + year + "</b>" 
    MongoClient.connect(url, function(err, db) { 
     //assert.equal(null, err); 
     if(err) { 
      res.send(err); 
      res.end(); 
     } 
     insertDocument(db, req, function(err,doc) { 
      if(err) 
       res.send(err); 
      else{ 
       setTimeout(function(){ 
        res.send(doc); 
        res.end(); 
       },2000); 
      } 
      db.close(); 
     }); 
    }); 
} 
} 

任何幫助表示讚賞。提前致謝！

我認爲問題出在你的HTML輸入字段

嘗試更改標有編號「ntaReqRefa」輸入欄下方

<input type="text" id="ntaReqRefa" name= "ntaReqRef" required 
autocomplete="off"/>
