JSON Throwing Error on Parsing

Question

Here is the JSON String I have. I have removed the opening and closing brackets from the JSON because I need to use the JSON values in jQuery to actually load the data in a select box:

{
    "text": "Pediatric FA, CPR & AED (2015)",
    "id": "128177000002431552~Pediatric FA, CPR & AED DVD Set (2015)~YES~117.19"
}, {
    "text": "FA, CPR & AED Manual (2015)",
    "id": "128177000002431564~FA, CPR & AED Manual (2015)~YES~17.73"
}

here is my Javascript Code

$.post("items.cfm",{"term":request.term})
                .done(function(data){
                    try{
                        var obj = JSON.parse(data),
                        values = [];
                        $.each(data, function(i, obj) {
                            values.push({"label":obj[x].text, "value":obj[x].id, "price":obj[x].id.split('~')[3]});
                        })
                        response(values);
                    }catch(e){
                        alert(e);
                    }
                })
                .fail(function(e){
                    alert(e);
                });

every time I run it I am getting the error

SyntaxError: Unexpected token , in JSON at position

Have you checked the browser console to see the actual JSON content returned from the HTTP request? And does it really say, "... at position" with no more information? — Pointy, Feb 24 '17 at 20:36
You can't have multiple objects in a JSON string unless they're encapsulated in square brackets as an array. Add a `[` and `]` on either end of the JSON string to make it valid. — Tyler Roper, Feb 24 '17 at 20:37
I said in my POST I am removing the start and end brackets, if i do not remove them then i get this error: `TypeError: Cannot use 'in' operator to search for '4592' in` — Hane, Feb 24 '17 at 21:07

You have two JSON objects separated by a comma. If you meant this to be an array, you need to surround it with array brackets:

[
{
    "text": "Pediatric FA, CPR & AED (2015)",
    "id": "128177000002431552~Pediatric FA, CPR & AED DVD Set (2015)~YES~117.19"
}, {
    "text": "FA, CPR & AED Manual (2015)",
    "id": "128177000002431564~FA, CPR & AED Manual (2015)~YES~17.73"
}
]

As a side note, if your server is generating invalid JSON, you should take a good look at the code that's producing the JSON. Chances are, there's code trying to generate this string by hand, which is a bad practice. The server should be using a library to convert the returned value into JSON.

@Hane: This other error you're getting is another issue entirely, [with its own fix](http://stackoverflow.com/a/18502129/120955). – StriplingWarrior Feb 24 '17 at 23:46
