如何使用node.js将表的所有行发送到Jade

Question

如何使用node.js将原始控制台值的所有行发送到Jade？ 此代码仅将WCF服务的1行发送给Jade。

var response = result['s:Envelope']['s:Body']  [0].OrderReportResponse[0].exeReport[0];
        console.dir(JSON.stringify(response));
        var marketOrder = response['a:MarketOrder'];
        for (var i = 0; i < marketOrder.length; i++) {
            var date = marketOrder[i]['a:SendingTime'];
            var time = marketOrder[i]['a:TransactTime'];
            var buyorSell = marketOrder[i]['a:Side'];
            var orderQty = marketOrder[i]['a:OrderQty'];
            var exchange = marketOrder[i]['a:Exchange'];
            var contractName = marketOrder[i]['a:ContractName'];
            var price = marketOrder[i]['a:Price'];
            var filled = marketOrder[i]['a:mFile'];
            var account = marketOrder[i]['a:Account'];
            var wrkQty = marketOrder[i]['a:WrkQty'];
            var execute = marketOrder[i]['a:ExeQty'];
            var undQty = marketOrder[i]['a:UndQty'];
            var type = marketOrder[i]['a:OrdType'];
            var modifier = marketOrder[i]['a:Modifier'];
            var trigPrice = marketOrder[i]['a:TrigPrice'];
            var status = marketOrder[i]['a:Status'];
            var avgPrice = marketOrder[i]['a:AvgPrice'];
            var tif = marketOrder[i]['a:TimeInForce'];
            var route = marketOrder[i]['a:Route'];
            var originator = marketOrder[i]['a:Originator'];
            var currentUser = marketOrder[i]['a:CurrentUser'];
            var algoName = marketOrder[i]['a:AlgoName'];
            var parentId = marketOrder[i]['a:ParentId'];
            var tTOrderId = marketOrder[i]['a:TTOrderId'];
            var ExchOrderId = marketOrder[i]['a:exchOrderId'];
            //console.dir(JSON.stringify(date, time, buyorSell, orderQty, exchange, contractName, price, filled, account, wrkQty, execute, undQty, type, modifier, trigPrice, status, avgPrice, tif, route, originator, currentUser, algoName, parentId, tTOrderId, ExchOrderId));
            res.render('aaa', {title: date, title1: time, title2: buyorSell, title3: orderQty, title4: exchange, title5: contractName, title6: price, title7: filled, title8: account, title9: wrkQty, title10: execute, title11: undQty, title12: type, title13: modifier, title14: trigPrice, title15: status, title16: avgPrice, title17: tif, title18: route, title19: originator, title20: currentUser, title21: algoName, title22: parentId, title23: tTOrderId, title24: ExchOrderId});
            return res.send();

Answer 1

您有两个主要错误。 首先，在Express中，每个视图只能渲染和发送一次响应。 其次，您的return调用导致循环在第一次尝试后立即退出，因此它仅返回第一行。 如果不是，则为return语句。 将这些调用嵌套在循环中将导致呈现最后一行。

避免在循环内嵌套渲染调用或响应发送-甚至根本不在Express视图内产生循环。 无需将25个局部变量发送到您的Jade模板； 只需将marketOrder响应对象发送到Jade模板，然后在模板内的对象上进行迭代即可将所有行附加到结果中。

您的Express路线代码应如下所示：

var response = result['s:Envelope']['s:Body'][0].OrderReportResponse[0].exeReport[0];
console.dir(JSON.stringify(response));
var marketOrder = response['a:MarketOrder'];
res.render('aaa', {orders: marketOrder});
return res.send();

在您的Jade模板中，我建议使用这样的mixin遍历行并将数据记录到控制台。 我没有为每个列硬编码tr值，而是将所有名称作为一个数组包含在mixin中以进行迭代。 为了使事情更干燥，我添加了一个条件，该条件允许mixin也用于thead行。

mixin tableRow(data)
      -
        var cols = ['SendingTime','TransactTime','Side','OrderQty',
        'Exchange','ContractName','Price','mFile','Account',
        'WrkQty','ExeQty','UndQty','OrdType','Modifier','TrigPrice',
        'Status','AvgPrice','TimeInForce','Route','Originator',
        'CurrentUser','AlgoName','ParentId','TTOrderId','exchOrderId']

      tr
            each col in cols
                  if data == 'head'
                        th=col
                  else 
                        td= data['a:' + col]

然后，在您的Jade文件的HTML中，遍历marketOrder数组以将行追加到表中，并记录该行各自的数据在服务器端，如下所示：

table
      thead
            +tableRow('head')
      tbody
            each row in marketOrder
                 - console.log(JSON.stringify(row))
                  +tableRow(row)

Answer 2

table（cell）mixin tableRow（data）-var cols = ['SendingTime'，'TransactTime'，'Side'，'OrderQty'，'Exchange'，'ContractName'，'Price'，'mFile'，'Account'， 'WrkQty'，'ExeQty'，'UndQty'，'OrdType'，'Modifier'，'TrigPrice'，'Status'，'AvgPrice'，'TimeInForce'，'Route'，'Originator'，'CurrentUser'，'AlgoName '，'ParentId'，'TTOrderId'，'exchOrderId']

  tr
        each col in cols
              if data==='head'
                    th=col
              else 
                    td= data['a:'+col]

表thead + tableRow（'head'）tbody＃tt订单中的每一行-console.log（row）+ tableRow（row）
