从服务器获取结果后，调用Meteor中的客户端js函数 [英] Invoke a client js function in Meteor after getting results from the server

问题描述

我正在尝试查看客户端从Meteor方法调用获得结果后如何调用js函数.我唯一能得到的就是仅在进行实际方法调用的客户端上调用函数myFunc. 有什么想法可以在所有当前订阅的客户端上调用该函数吗?

I'm trying to see how can I invoke a js function after the client gets a result from a Meteor method call. The only thing I was able to get is to invoke the function myFunc only on the client that made the actual method call. Any thoughts how i can invoke the function on all the currently subscribed clients?

下面是代码:

function myFunc(error, result)  {
  alert(result);
}
if (Meteor.is_client) {

  Template.container.events = {
    'click input' : function () {
      Meteor.call('someMethod',myFunc);
      if (typeof console !== 'undefined')
        console.log("You pressed the button");
    }
  };
}



if (Meteor.is_server) {
  Meteor.startup(function () {
    // code to run on server at startup
  });
}

Meteor.methods({
  someMethod: function() {
    //console.log(!this.is_simulation);
    return "something";
  }
})

谢谢

推荐答案

当前，您不能直接向所有客户端广播方法调用.至少据我所知.但是一种解决方法是创建一个名为Alerts的集合并监视它的更改.然后，当您要将消息发送给所有用户时，可以在警报"中更改文档:

Currently you can't broadcast a method call to all clients directly. At least as far as I can tell. But a work around would be to create a collection called Alerts and monitor it for changes. Then when you want to send a message to all your users you can change the document in Alerts:

客户:

Alerts = new Meteor.Collection("alerts")

Meteor.autosubscribe(function() {
  Alerts.find().observe({
    added: function(item){ 
      alert(item.message);
    }
  });
});

服务器:

Alerts = new Meteor.Collection("alerts")

Meteor.publish("alerts", function(){
 Alerts.find();
});

Alerts.remove({}); // remove all
Alerts.insert({message: "Some message to show on every client."});
