Based on my understanding I have created below logic to create your payload. This code create exact structure you want to send as payload. In my code I have created mainData array to create payload. In your case you need to pass this mainData as your ajax payload data. Hopefully this will solve your problem

 var mainData={}; $(document).ready(function(){ $("#submit").click(function(){ mainData='{'+'\\n'+ '"name":'+ $("#name").val()+',\\n'+ '"mobile": '+$("#mobile").val()+',\\n'+ '"email": '+$("#email").val()+',\\n'+ '"address": '+$("#address").val()+',\\n'+ '"localityID": '+$("#localityID").val()+',\\n'+ '"cityID": '+$("#cityID").val()+',\\n'+ '"bookingDate":'+$("#bookingDate").val()+',\\n'+ '"timingID": '+$("#timingID").val()+',\\n'+ '"paymentType":'+$("#paymentType").val()+',\\n'+ '"affiliateID": '+$("#affiliateID").val()+',\\n'+ '"key": '+$("#key").val()+',\\n'+ '"password":'+$("#password").val()+',\\n'+ '"orderItems": '+$("#orderItems").val()+'\\n'+ ' });'; console.log("mainData="); console.log(mainData); }); }); 

 <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"> </script> <input type="text" id="name" placeholder="Name"/> <input type="number" id="mobile" placeholder="Mobile"/> <input type="text" id="email" placeholder="Email"/> <input type="text" id="address" placeholder="address"/> <input type="text" id="cityID" placeholder="City ID"/> <input type="text" id="localityID" placeholder="Locality ID"/> <input type="date" id="bookingDate" placeholder="Booking Date"/> <input type="text" id="timingID" placeholder="Timing ID"/> <input type="text" id="paymentType" placeholder="Payment Type"/> <input type="text" id="affiliateID" placeholder="Affiliate ID"/> <input type="text" id="key" placeholder="Key"/> <input type="password" id="password" placeholder="Password"/> <textarea type="text" id="orderItems" placeholder="order Items"></textarea> <input type="submit" id="submit" /> 

After created payload from above code you can pass payload in your ajax as follows

function _getTest(){
                $.ajax({
                url: "domain.com",
                type: "POST",
                contentType: 'application/json; charset=utf-8',
                data: JSON.stringify(mainData),              
                    success: function(data) {
                        console.log(data);
                    },
                    error: function(result) {
                        alert(result.responseText);
                    }
                });
            }
