Github API get the link header with ajax

Question

I'm using github api for a small web app and at some point I need to get link header for the pagination.

The final goal is to get the total number of commits per repository, I found that python script and tried to adapt it to JavaScript.

getData = $.getJSON('https://api.github.com/repos/'+user+'/'+repo+'/commits?callback=?', function (commits){

    console.log(getData.getResponseHeader('link'))
    // will return null

    console.log(getData.getAllResponseHeaders('link'))
    // will return an empty string

    console.log(commits)
    // will successfuly return my json
});

user and repo are respectively the user name and his repo name

It's for a Github page so I can only use JavaScript.

See the GitHub API docs for using JSONP callbacks: http://developer.github.com/v3/#json-p-callbacks

Basically, if you're using JSONP to call the API, then you won't get a Link header, but you will instead get the same information in the response JSON document (i.e. the body). Below is the example from the API docs, notice the Link property in the meta object

$ curl https://api.github.com?callback=foo

foo({
  "meta": {
    "status": 200,
    "X-RateLimit-Limit": "5000",
    "X-RateLimit-Remaining": "4966",
    "Link": [ // pagination headers and other links
      ["https://api.github.com?page=2", {"rel": "next"}]
    ]
  },
  "data": {
    // the data
  }
})
