問題描述

我正在使用node.js進行發票項目，其中我必須在字符串中存儲多個產品，而我的代碼是

架構文件 

var mongoose = require('mongoose');

var autoIncrement = require('mongoose-auto-increment');
var invoiceSchema = mongoose.Schema({

date: String,
documentNo:Number,
vendorName:String,
pno:Number,
productName:String,
description:String,
quantity:Number,
costPrice :Number,
mrp:Number,
invoiceNo:Number,
advance:Number,
due:Number,
discount:Number,
Tax : String,
netTotal:Number,
size:String,
colour:String,
grandTotal:Number

},{collection:'invoice-data'});

var invoice = module.exports = mongoose.model('invoice',invoiceSchema);

現在用於路由 

var product = require('../models/product');
var invoice= require('../models/invoice.js');
exports.addaInvoice=function(req, res) {
var date=req.body.date;
var invoiceNo=req.body.invoiceNo;
var vendorName = req.body.vname;
var pno = req.body.orderNo;
var productName = getElementById(req.body.productname);
var description = req.body.desc;
var colour = req.body.colour;
var size = req.body.size;
var quantity = req.body.quantity;
var costPrice = req.body.costPrice;
   var mrp = req.body.mrp;
     var amount=req.body.amount;
     var discount=req.body.discount;
     var discountvalue=req.body.discountvalue;
     var netamount=req.body.netamount;
var advance = req.body.advance;
var due = req.body.due;
var Tax = req.body.Tax;
var netTotal = req.body.netTotal;
var subTotal = req.body.subTotal;
var grandTotal = req.body.grandTotal;

    var newInvoice = new invoice({
            date: date,
            invoiceNo:invoiceNo,
            vendorName:vendorName,
            pno:pno,
            productName:productName,
            description:description,
            colour:colour,
            size:size,
            quantity:quantity,
            costPrice :costPrice,
            amount:amount,
            discount:discount,
            discountvalue:discountvalue,
            netamount:netamount,
            mrp:mrp,
            advance:advance,
            due:due,
            Tax :Tax,
            netTotal:netTotal,
            subTotal : subTotal,
            grandTotal : grandTotal
   });
    newInvoice.save();
            req.flash('success_msg',' purchase invoice added ')
    res.redirect('/users/invoicedetails');

}

HTML代碼

function calculate()
 {
    var quantity = document.getElementById('quantity');
    var costprice = document.getElementById('costprice');

    //var amount = document.getElementById('amount');
var result=quantity.VA*costprice.value;
    //amount.value = result;
$("#amount").val(result);

  }</script>
<SCRIPT language="javascript">
    function addRow(tableID) {

        var table = document.getElementById(tableID);

        var rowCount = table.rows.length;
        var row = table.insertRow(rowCount);

        var colCount = table.rows[0].cells.length;

        for(var i=0; i<colCount; i++) {

            var newcell = row.insertCell(i);

            newcell.innerHTML = table.rows[0].cells[i].innerHTML;
            //alert(newcell.childNodes);
            switch(newcell.childNodes[0].type) {
                case "text":
                        newcell.childNodes[0].value = "";

                        newcell.childNodes[0].checked = false;

這是我的html代碼，腳本用於克隆表格，用於在tablle中添加一行以進行多個產品輸入

現在，如果我有2個或更多產品，這將適用於一種產品

如何將這三種產品保存在與購買發票相同的文檔中

2 個解決方案

如果您使用的是bodyParser中間件，則可以從客戶端傳遞值數組。

在客戶端，您可能需要按如下方式命名輸入元素 

<input name="products[#{1}][productname]" type="text">
<input name="products[#{1}][description]" type="text">

<input name="products[#{2}][productname]" type="text">
<input name="products[#{2}][description]" type="text">

等等

這樣你的請求體就會有 

{
    "products": {
        "1": {
            "product name": "name goes here ",
            "description": "desc goes here "
        },
        "2": {
            "product name": "name goes here",
            "description": "desc goes here"
        }
    }
}

您可以迭代並獲取路由器中的值 

var products = Array.prototype.slice.call(request.body.products);
for (var i = 0; i < messages.length; i++) {
    var newInvoice = new invoice({
        productName: products[i].productname,
        description: products[i].description
    });
    newInvoice.save();
});

首先，您需要更改發票架構，以在其中添加多個產品。 您需要添加一系列產品子文檔，我在下面添加了一個示例模式 

// Product Schema 
var ProductSchema = mongoose.Schema({
    pno:Number,
    productName:String,
    description:String,
    quantity:Number,
    costPrice :Number,
    mrp:Number,
    size:String,
    colour:String,
});


var invoiceSchema = mongoose.Schema({
   date: String,
   documentNo:Number,
   vendorName:String,
   products: [ProductSchema],
   invoiceNo:Number,
   advance:Number,
   due:Number,
   discount:Number,
   Tax : String,
   netTotal:Number,
   grandTotal:Number
},{collection:'invoice-data'});

我沒有在語法上檢查這段代碼，如果你想在一個文檔中存儲多個子文檔，我只是想知道如何創建模式。

在您的node.js代碼中，您還需要保存一系列產品 

var productArr = [];
var temProduct = {};

temProduct.pno= pno;
temProduct.productName= productName;
temProduct.description= description;
temProduct.colour= colour;
temProduct.size= size;
temProduct.quantity= quantity;
temProduct.costPrice = costPrice;
temProduct.amount = amount;
temProduct. = mrp;


productArr.push(temProduct);
var newInvoice = new invoice({
        date: date,
        invoiceNo:invoiceNo,
        vendorName:vendorName,
        products:productArr,
        advance:advance,
        due:due,
        Tax :Tax,
        netTotal:netTotal,
        subTotal : subTotal,
        grandTotal : grandTotal
   });

  newInvoice.save(function(err, new_data) {
      if(err) {
          // Handle error here, if any come
      } else {
          req.flash('success_msg',' purchase invoice added ')
          res.redirect('/users/invoicedetails');
      }
  });

您可以像在productArr中一樣推送產品，然后將其添加到發票對象中，然后保存。

我再次提到，上面的代碼不好直接運行，你需要做一些改動，但它會讓你知道如何做到這一點。
