从方法调用填充模板

<template name="myTemplate">
  {{#each results}}
    <div><span>{{name}}</span><span>{{age}}</span></div>
  {{/each}}
</template>

Template.myTemplate.onCreated(function() {
  this.results = new ReactiveVar();
  Meteor.call('myMethod', (error, result) => {
    if (error) {
      // do something with the error
    } else {
      // results is an array of {name, age} objects
      this.results.set(result);
    }
  });
});

Template.myTemplate.helpers({
  results() {
    return Template.instance().results.get();
  }
});
