javascript - 错误 : Failed to execute 'insertBefore' on 'Node'

Question

我尝试插入 <div> {{#each}} 周围的容器，但效果不佳。这也很奇怪，因为它适用于 2 个正常的帖子列表页面，但不适用于按距离排序的第 3 个页面。

更新:我注意到在我将模板 JS 从 template.name.onRendered 更改之后至 onCreated ，排序页面有效。但是，只有当您从以前的帖子列表页面而不是个人资料页面转到时，它才有效。

错误页面的唯一共同点是那些页面使用 publishComposite 进行排序。这可能是问题所在，因为 publishComposite 有父子关系吗？

错误信息

Answer 1

试试这个，让我知道:

Template.nearShops.onCreated(function () {  
  var self = this;
  self.autorun(function () {
    self.interval = Meteor.setInterval(function(){
      var currentLocation = Geolocation.latLng() || '';
      if(currentLocation) {
        Session.set('lat', currentLocation.lat);
        Session.set('lng', currentLocation.lng);
      }
    }, 2000);   
  });
  self.autorun(function(){  
    if(Session.get('lat')) {
      self.subscribe( "nearShops", Session.get('lng'), Session.get('lat') );
    }
  });
});

如果可行，我会做出解释
