    javascript - Backbone.js: Build JSON array from collection - Stack Overflow

    programmeradmin4浏览0评论

    I have a backbone collection Platforms. The structure of Platforms looks like this:

    Platforms
  PlatformList
    models
      0: Platform
        attributes
          id: 1
          name: "some name"
      1: Platform
        attributes
          id: 2
          name: "some other name"

    I need to extract the attributes from the models within the collection, and build a JSON array in the following format:

    [{"id":1,"name":"some name"},{"id":2,"name":"some other name"}]

    Calling Platforms.models.toJSON() or JSON.stringify(Platforms.models) results in a literal string "[[object Object], [object Object]]"

    How can I build the JSON array that I need from this collection?

    • 1 Taking a quick look at the annotated source code, it looks like you might try Platforms.toJSON() – Dustin Graham Commented Mar 5, 2012 at 16:01

    Reset to default 14

    you should not do platforms.models.toJSON() but instead call toJSON on the collection itself!

    Platforms.toJSON()

    check the following jsfiddle on this solution http://jsfiddle/saelfaer/TP9NE/2/
