Question

我有这个代码试图将文档（记录）插入MongoDB集合（表）：

do
{
//statement here
}
while(condition)

它不起作用。在Chrome开发工具（F12）控制台中输入以下内容：

TimeAndSpace = new Mongo.Collection('timeAndSpace');

if (Meteor.isClient) {
    Template.addTimeSpaceForm.events({
        'submit form': function() {
            event.PreventDefault();
            var city = "Fort Bragg";
            var state = "California";
            var yearin = 1958;
            var yearout = 1959;
            // var city = event.target.city.value;
            // var state = event.target.state.value;
            // var yearin = event.target.yearin.value;
            // var yearout = event.target.yearout.value;
            Meteor.call('insertLocationData', city, state, yearin, yearout);
        }
    });

}

if (Meteor.isServer) {
  Meteor.startup(function () {
    // code to run on server at startup
  });
}

Meteor.methods({
    'insertLocationData': function(city, state, yearin, yearout) {
        console.log('attempting to insert a record');
        TimeAndSpace.insert({
            ts_city: city,
            ts_state: state,
            ts_yearin: yearin,
            ts_yearout: yearout
        });
    }
});

...返回＆＃34; []＆＃34; - 显然表明收藏品没有文件。

控制台在点击＆＃34; Add Place Lived＆＃34;提交按钮是：

TimeAndSpace.find().fetch()

如果您需要/需要知道，这里是HTML：

XHR finished loading: GET "http://localhost:3000/sockjs/info?cb=jmghsx3ec6".

我失踪或失火的原因是什么？

因为你犯了一些小错误并且错过了错误。例如，您在函数中缺少事件。然后你尝试PreventDefault而不是正确的preventDefault。此外，方法应仅放在服务器端。我也冒昧地将它用于你的表格。这是代码和功能性流星垫的链接。

TimeAndSpace = new Mongo.Collection('timeAndSpace');

if (Meteor.isClient){
    Template.addTimeSpaceForm.events({
        'submit form': function(event){
            event.preventDefault();
            var city = event.target.city.value;
            var state = event.target.state.value;
            var yearin = event.target.yearin.value;
            var yearout = event.target.yearout.value;

            Meteor.call('insertLocationData', city, state, yearin, yearout);
            console.log(TimeAndSpace.find().fetch());
        }
    });
}

if (Meteor.isServer){
  Meteor.methods({
      'insertLocationData': function(city, state, yearin, yearout){
          console.log('attempting to insert a record');
          TimeAndSpace.insert({
              ts_city: city,
              ts_state: state,
              ts_yearin: yearin,
              ts_yearout: yearout
          });

          console.log(TimeAndSpace.find().fetch());
      }
  });
}

为什么不将文档插入MongoDB集合？
