Question

我希望你帮助我。当我改变订阅时会发生一些奇怪的事情。因此，订阅中未显示的数据会显示一会儿。在这里我的消息来源：
1.自动运行等待分页：

    template.autorun(function (computation) {
      if (Session.get('factors.page.ready') || Session.get('rules.page.ready')) {
        var factors;
        var userIds = Factors.find({},{sort :Session.get('factors.sort')}).map(function (factor) {
        return factor.creator;
      });
      Meteor.setTimeout(function () {
        factors = Factors.find({},{sort :Session.get('factors.sort')}).fetch();
        Meteor.call('factors.getUserCount', _.pluck(factors, '_id'), function (err, counts) {
          if (err) return;
          _.forEach(counts, function (obj) {
            var factor = _.find(factors, function (factor) {
              return factor._id === obj._id;
            });

            if (factor) factor.userCount = obj.count;
          });
          if(!computation.firstRun) {
              template.factors.set(factors);
          }
        });
      }, 15);

      template.subscribe('users.names', { _id: { $in: userIds } });
    }
    });

也是分页autoruns：

template.autorun(function () {
    var options = Session.get(collection + '.options') || {};
    var sort = Session.get(collection + '.sort');
    var page = Session.get(collection + '.page') || template.page.get() || 1;
    if (!options.limit || typeof options.limit !== 'number') {
      options.limit = 10;
    }

    options.skip = (page - 1) * options.limit;
    if (sort) options.sort = sort;

    // create a subscription with parameters
    sub = Meteor.subscribe(collection, {
      filters: Session.get(collection + '.filters'),
      options: options,
      assignFirst: Session.get(collection + '.assignFirst')
    });
  });

  template.autorun(function () {
    var page = template.page.get() || 1;
    var options = Session.get(collection + '.options') || {};
    var limit = options.limit || 10;
    var visiblePagesNum = options.visiblePagesNum || 7;
    var visiblePagesHalf = (0 | (visiblePagesNum - 1) / 2);
    var visiblePages = [];
    // wait for ready
    if (sub.ready()) {
      count = Counts.get(collection) || limit;
      // get array of pages, i.e. [1, 2, 3...]
      pages = _.range(1, Math.ceil(count / limit) + 1);


      if (page - visiblePagesHalf < 1){
        visiblePages = _.first(pages, visiblePagesNum);
      }else{
        if(page + visiblePagesHalf > pages.length){
          visiblePages = _.last(pages, visiblePagesNum);
        }else{
          visiblePages = _.range(page - visiblePagesHalf, page + visiblePagesHalf + 1);
        }
      }
        // set first page if there is only one
      if (page !== 1 && (pages.length === 1)){
        template.page.set(1);
      }

      Session.set(collection + '.page', page);

      // set amount of pages for pagination
      template.pages.set(pages);
      // set visible pages
      template.visiblePages.set(visiblePages);
      if (collection === 'logs') {
        Meteor.setTimeout(function() {
          Session.set(collection + '.page.ready', true);
        }, 200);
      } else {
        Session.set(collection + '.page.ready', true);
      }
    } else {
      Session.set(collection + '.page.ready', false);
    }
  });

在页面上传输数据的助手：

factors: function () {
  return Template.instance().factors.get();
},
