Question

I’m doing pretty simple thing here: getting Facebook news feed using their graph API. I’m receiving the json object and fetching it to the page. “Likes” come as an array of JSONs (obviously) like so:

data.likes:

{
    "count":2,
    "data":[
        {"name":"Jennifer Doe","id":"{user_id}"},
        {"name":"John Doe","id":"{user_id}"}
    ]
}

My goal is to know if the current user liked it or not – assume that I have current user’s user_id. So, what’s the simplest way to check if the current user is liked this post or not?

I know I can set up for loop and go through each data, but that’s not only inefficient, but also looks bad. I can also use $.inArray() and look for particular JSON object, but I want to be able to search by user_id only.

Any help would be appreciated. Thanks!

Two solutions come to my mind immediately:

-a for loop like this

for (jsonobj in data.likes.data){
  //scan each jsonobj for the user
}

-you could alternatively convert the JSON object in a string with

JSON.stringify(jsonobj)

and then search in it for the user id with some search method (for example ‘search’: http://www.w3schools.com/jsref/jsref_search.asp or also indexOf: http://www.w3schools.com/jsref/jsref_indexof.asp).

if you need more details I can elaborate on this.
