如何读取Meteor中特定字段的值

Question

Template.CompanyEntry.helpers({
    companies: function() {
      var Company= Companies.find();
      console.log (Company); 
      var id = Company._id; 
      Session.set('CurrentCompany',id); 
      alert (Session.get('CurrentCompany')); 
      return Company; 
    }
})

我正在尝试从文档中读取特定值。我该怎么做？

喜欢这个。

var CompanyId = Companies.findOne({TargetName: TargetValue}, {fields: {_id: 1}); var id = CompanyId._id;

或者如果你不想使用findOne，因为find更有效

var CompanyArray = Companies.find({TargetName: TargetValue}, {fields: {_id: 1}, limit: 1}).fetch(); var id = CompanyArray[0]['_id'];
