正在尝试更新数据库。
为此,我这样做
从js代码

var data = {
    "jobid": $('#jobid').val(),
    "names": $('#names').val(),
    "scripttype": $('#testscripts').val()
};
var msg="";
for(i = 1; i <=4; i++) {
    data["Param" + i + "Key"] = $('#key' + i).val();
    data["Param" + i + "Value"] = $('#value' + i).val();
}
        $.ajax({
            type: 'post',
            url: "/save",
            dataType: "json",
            data: data
        });

在node.js方面
jobsCollection.update({
            _id: id
        }, {
            $set: {
                names: record.names,
                script: record.scripttype,
                // i dont know what should i place in this part???
               //   i have to set paramkey and paramValues
            }
        },
                     {
             upsert: true
             },
        function (err, result) {
            if (!err) return context.sendJson([], 404);
        });

在record.names和record.script类型中获取正确的值。
I don't know how to set values got from the for loop for updating

request going

Request: /save
{ jobid: '',
  names: 'first',
  scripttype: 'fow',
  Param1Key: '1',
  Param1Value: 'oneeeeee',
  Param2Key: '2',
  Param2Value: 'twoooooooo'
  etc........
  ............
 }

最佳答案

由于属性名称是动态的,因此您需要使用JavaScript的索引器样式属性访问器,如下所示。

基本上只需逆转该过程即可。我不确定数据在您调用update的位置,因此在以下示例中将其称为sourceData

// create an object with the well known-property names
var set = {
    names : record.names,
    script : record.scripttype
};

// now loop through the params and set each one individually
for(i = 1; i <=4; i++) {
    var key = "Param" + i + "Key";  // build a key string
    set[key] = sourceData[key];     // grab the data and set it
    key = "Param" + i + "Value";    // and repeat
    set[key] = sourceData[key];
}


然后,将其传递给您的更新:

jobsCollection.update({
            _id: id
        }, {
            $set: set          // pass the object created above
        }, /* etc. */


如果您不知道Params的计数,则可以:


发送
改用for .. in遍历所有属性


对于#2:

for(var key in sourceData) {
    // you could filter the property names here if you'd like
    // (like if only Params# were important)
    set[key] = sourceData[key];
}
