推荐答案

只是为了让你开始:

YourData = new Meteor.Collection("yourdata");

// Create
YourData.insert({text: "Some text in this record"});

// Get
var record = YourData.findOne();
var receivedTextFromDatabase = record.text;
console.log("Text: " + receivedTextFromDatabase);

// Update
YourData.update({_id: record._id}, {$set: {text: "Changed this text"}});

然后，您必须在模板中声明使用此集合 (YourData).更新集合将自动更新您的模板和 html.文档实际上相当不错——请查看.

Then you'll have to declare the use of this collection (YourData) in your templates. Updating the collection will then automatically update your template and html. The documentation is actually pretty good—check it out.
