是否有可能从内部调用服务器方法observeMeteor 中的回调？
我整理了一个重现该问题的示例，即Meteor.call()从回调中调用myCursor.observe()不执行。当从观察回调中调用时，Meteor.method它本身也不会回调错误，它只是返回Undefined.
别再无视我了Meteor.call():) 非常感谢任何帮助！
观察.js
items=new Meteor.Collection("Items");
if (Meteor.isClient) {
Meteor.subscribe("Items");
Meteor.startup(function(){
itemsCursor=items.find();
itemsHandle=itemsCursor.observe({
added : function(doc){
console.log("added "+doc.text);
Meteor.call('aMethod',doc.text,function(e,r){
if(e){
console.log("error from server: "+e);
}else{
console.log("response from server: "+r);
}
});
},
removed : function(doc){
console.log("removed "+doc.text);
Meteor.call('aMethod',doc.text,function(e,r){
if(e){
console.log("error from server: "+e);
}else{
console.log("response from server: "+r);
}
});
}
});
});
Template.test.items=function(){
return items.find();
}
Template.test.events({
'click #add':function(){
items.insert({"text":"Timestamp: "+(new Date().getTime())});
},
'click #remove':function(){
items.remove(items.findOne()._id);
}
});
}
if (Meteor.isServer) {
Meteor.publish("Items",function(){
return items.find();
});
items.allow({
insert : function(userId,doc){
return true;
},
update : function(userId,doc){
return true;
},
remove : function(userId,doc){
return true;
}
});
Meteor.methods({
aMethod:function(text){
console.log("Got it! "+text);
return "Got it! "+text;
}
});
}
