Question

我不知道我必须做些什么才能让它在这里工作是代码：

Songs = new Mongo.Collections("songs");

if (Meteor.isClient) {
  // counter starts at 0
  Session.setDefault('counter', 0);

  Template.hello.helpers({
    counter: function () {
      return Session.get('counter');
    }
  });

  Template.hello.events({
    'click button': function () {
     // increment the counter when button is clicked
      Session.set('counter', Session.get('counter') + 1);
    }
  });
}

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

这是错误： TypeError：undefined不是函数在newapp.js：1：9

我所做的只是添加1行。另外，我如何在浏览器Javascript控制台中运行相应的Javascript代码，以将项目插入到Songs集合中。我是初学者。

使用JSONObject paramsVolley = new JSONObject(); try { paramsVolley.put("u_id", 4); } catch (JSONException e1) { e1.printStackTrace(); } JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST, "http://admin:1234@greentin.com/apiuser/getuserdet/format/json", paramsVolley, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { Toast.makeText(getApplication(), response.toString(), Toast.LENGTH_SHORT).show(); } @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String, String> headers = new HashMap<>(); String credentials = "admin:1234"; String auth = "Digest " + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP); headers.put("Content-Type", "application/json"); headers.put("Authorization", auth); return headers; } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError e) { Toast.makeText(getApplicationContext(), "Error Occurred",Toast.LENGTH_SHORT).show(); } }); GoGreen.getInstance().addToRequestQueue(jsonObjReq, tag_update_det);代替Mongo.Collection。最后Mongo.Collections没有必要。

只在顶部
