javascript - 将 mongo 返回的对象中的键值存储在 Meteor 中

Question

好吧，我只想说我是 meteor 新手，正在绞尽脑汁。我有一位客户声明的收藏品。它有常见的客户字段、地址、城市、邮政等。

我对此集合进行以下调用以返回一条记录。

var customerRecord = customersColl.find({customerName: suggestion.value}).fetch();

这成功返回了一个包含我的客户记录的对象。现在我需要做的是将地址、城市邮政等这些值分配给变量。这就是我失败的地方。我尝试过的每一种方法都会出现错误或未定义。我如何让以下内容发挥作用:

var customerAddress = customerRecord.customerAddress.value;

这是我用于该对象的方案。

customersColl.attachSchema(new SimpleSchema({
    customerName:{
    type: String,
    label: "Customer:"
    },
    customerSuite: {
        type: String,
        optional: true,
        label: "Suite:"
    },
    customerAddress: {
        type: String,
        label: "Address:"
    },
    customerCity: {
        type: String,
        label: "City:"
    },
    customerState: {
        type: String,
        label: "State/Prov:"
    },
    customerZip: {
        type: String,
        label: "Zip/Postal"
    },
    customerPhone1: {
        type: String,
        label: "Phone 1:"
    },
    customerPhone2: {
        type: String,
        optional: true,
        label: "Phone 2:"

        regEx: SimpleSchema.RegEx.Email,
        optional: true,
        label: "Email 4:"
    },      
}));

这不起作用，但我尝试过的任何事情都没有起作用。对此的任何帮助将不胜感激。

更正代码

这是现在可与 findOne 配合使用的正确代码。谢谢大家的帮助。

        var customerRecord =  customersColl.findOne({customerName: suggestion.value});
        console.log(customerRecord.customerAddress);

fetch返回文档数组。您似乎期望检索单个文档，因此您应该使用 findOne相反:

var customerRecord = customersColl.findOne({customerName: suggestion.value});
