html文件中有一段代码：

    {{#each answer in question.answers}}
                    <div id="answer-option-wrapper-{{randomId}}" class="col-md-12 question-answer-option--wrapper">
                        <div class="col-md-12 question-answer-option">
                            <input class="col-md-1" style="margin-top: 0.5em;" name="answer" type="{{radioOrCheckbox question}}">
                            <input id="{{randomId}}" type="text" placeholder="Вариант ответа" class="col-md-10 question-field-answer" style="" value="{{answer}}">

                            <div class="col-md-1 delete-answer-option" style=""><i style="padding:2px"
                                                                                                                                         class="btn btn-danger fa fa-trash"
                                                                                                                                         aria-hidden="true"></i></div>
                        </div>

                    </div>
                {{/each}}

我使用 id 以防万一。question.answers是一个数组。有一个处理程序change .question-field-answer可以更新数据库中的这个值。不直接修改 DOM。

问题是在相同的值的answers情况下，如果您更改输入中的文本，该文本会出现在相邻的输入中。有时从上面，有时从下面。在mongo集合本身中，所有内容通常都会更新。我怀疑它meteor使用字符串值作为键（为什么不使用数组中的索引？）。

我这样跑

meteor debug


W20180909-12:13:05.082(3)? (STDERR) Debugger listening on [::]:5959
W20180909-12:13:07.380(3)? (STDERR) Debugger listening on [::]:5959
W20180909-12:13:07.758(3)? (STDERR) Note: you are using a pure-JavaScript implementation of bcrypt.
W20180909-12:13:07.758(3)? (STDERR) While this implementation will work correctly, it is known to be
W20180909-12:13:07.758(3)? (STDERR) approximately three times slower than the native implementation.
W20180909-12:13:07.759(3)? (STDERR) In order to use the native implementation instead, run
W20180909-12:13:07.759(3)? (STDERR) 
W20180909-12:13:07.759(3)? (STDERR)   meteor npm install --save bcrypt

W20180909-12:13:07.759(3)? (STDERR) in the root directory of your application.

然后如何开始调试？这是什么意思？

你好！一个小问题，开始在 Meteor 上编写应用程序是否值得？他是活着还是死了？据我所知，当前版本是 1.5.1。

伙计们请告诉我如何通过添加表单将图像添加到产品中 https://jsfiddle.net/2gvcfqh5

// коллекция
Items = new Mongo.Collection('items');

// менеджер шаблона
Template.itemAdd.events({
  'submit form': function(e) {
    e.preventDefault();
    function slugify(text) {
        return text.toString().toLowerCase()
          .replace(/\s+/g, '-')        // Replace spaces with -
          .replace(/[^\w\-]+/g, '')   // Remove all non-word chars
          .replace(/\-\-+/g, '-')      // Replace multiple - with single -
          .replace(/^-+/, '')          // Trim - from start of text
          .replace(/-+$/, '');         // Trim - from end of text
    };

    var imgArr = document.getElementById("imgItem").files;
    var item = {
      price: $(e.target).find('[name=price]').val(),
      title: $(e.target).find('[name=imgItem]').val(),
      titleSlug: slugify($(e.target).find('[name=title]').val()),
      img: imgArr
    };

    Meteor.call('itemInsert', item, function(error, result) {
      if (error) {
        return throwErrors(error.reason);
      }

      Router.go('itemPage', {_id: result._id});

    });
  }
});


//публикация
Meteor.publish('items', function () {
  return Items.find();
});

Meteor.methods({
  itemInsert: function (itemAttributes) {
    //check(Meteor.userId(), String);
    check(itemAttributes, {
      title: String,
      price: String,
      titleSlug: String,
      img_src: Object,
    });

    var item = _.extend(itemAttributes, {
      createdAt: new Date(),
    });

    var itemId = Items.insert(item);
    return {
      _id: itemId
    };
  }
});


// router

Router.configure({
  layoutTemplate: 'layout',
  loadingTepmlate: 'loading',
  waitOn: function () {
    return Meteor.subscribe('items');
  }
});

Router.route('/', {
  name: 'itemsList'
});

Router.route('/item/:_id',{
  name: 'itemPage',
  data: function () {
    return Items.findOne(this.params._id);
  }
});

Router.route('/add',{
  name: 'itemAdd'
});

Router.onBeforeAction('loading');
<template name="itemPage">
  <h1>{{title}}</h1>
  <p><span class="fz24">{{price}}</span> <i class="glyphicon glyphicon-ruble"></i></p>
</template>
