我尝试在{{#each}}周围插入<div>
个容器,但它不起作用。它也很奇怪,因为它适用于2个普通帖子列表页面,但不适用于按距离对它们进行排序的第3个页面。
更新
我注意到,在将模板JS从template.name.onRendered
更改为onCreated
后,排序页面正常工作。但是,只有当您从之前的帖子列表页面而不是从个人资料页面开始时,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,因为publishComposite具有子到父关系吗?
错误消息

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') );
}
});
});
如果这项工作我会解释

我通过将 cdk 从版本 9 更新到 11 来修复它。
我的情况:将 mat-card(cdkDrag) 嵌入到 mat-grid-list(cdkDropListGroup)/mat-grid-tile
