jQuery DataTable不适用于流星

Question

I am trying to implement jQuery DataTables in my Meteor project, but I am always getting the following error. Can someone please tell me what I am missing / doing wrong here? Below is my Meteor app code. Thanks.

Uncaught TypeError: Cannot set property 'pagesData' of undefined underscore.js:848

Project.html - Client folder

<template name="projectslist">
  <div class="projectslist">

    <div>
        {{> DataTable dtProjects }}
    </div>

  </div>
</template>

Projectlist.js - Client folder

Template.projectslist.dtProjects =  function() {    
  return {
    id: "my-unique-table-id",
    columns: [
      {
        title: "Name",
        data: "name"
      }, {
        title: "Description",
        data: "description"
      }, {
        title: "Delivery Date",
        data: "deliverydate"
      }
    ],
    subscription: "dtProjects",
    query: {
      grade: "A"
    }
  };
};

Server.js - Server Folder

var ProjectsTable;
  ProjectsTable = new DataTableComponent({
    subscription: "dtProjects",
    collection: Projects
  });
  ProjectsTable.publish();

Projects.js - Available for both Server and Client:

Projects = new Mongo.Collection('projects');

As per meteor-talk , JQuery dataTables duplicates a lot of the sorting and DOM manipulation functions that MiniMongo, Spark, and Spacebars provide. So even if you can get the styling sorted out (or decided to ignore styling), sorting and other functions wind up not behaving like one is expecting when the table reactively updates underneath DataTables.

Having said so, on July 30, 2014 Austin Rivas, the creator of the meteor-jquery-datatables (which menway - creator of the menway:jquery-datatables package forked to create the Meteor Datatable package) mentioned in Meteor Google support groups:

There are lots of difficulties with using jquery-datatables and meteor together do to duplicate functionality and having to reconcile jquery-datatables dom state with meteor reactivity.

So it might be a good idea to check another package or possibly check alternative approaches for pagination: https://github.com/awatson1978/clinical-ui-crud-table

Personally I would recommend Reactive Table https://github.com/ecohealthalliance/reactive-table . It is quite stable, easy to implement / configure.

Answer 2

1. Remove the mrt version:

   mrt remove jquery-datatables

2. Add the Meteor 0.9+ version:

   meteor add menway:jquery-datatables

However, it seems like it is still not 0.9 compatible as package.js still uses spacebars. Give it a shot, though.

Maybe it's worth looking at this extension instead: https://atmospherejs.com/ephemer/reactive-datatables
