I have a little problem in picking up the data from the JSON actually can get some data, however when you have the occurrence of "/_string" the script error.

example:

JSON

"results":[{
price_value_prices: 15.05
price_value_prices/_currency: "USD"
price_value_prices/_source: "$15.05" 
}];

AJAX

$.ajax({
  type: 'GET',
  url: $url,
  dataType: 'json',
  success: function (data) {
    data.results[$n].price_value_prices/_sources
  }
});

console log output

_sources is not defined

how can I solve this problem?

• 4 The problem is because your JSON is invalid - all keys and values must be wrapped in quotes, eg: "price_value_prices/_source": "$15.05". If you fix that you can then access the property using data.results[$n]['price_value_prices/_sources'] – Rory McCrossan Commented Dec 19, 2015 at 12:07

First thing, your JSON is invalid without the quotes on the left side for the field names, so change it to:

"results":[{
  "price_value_prices": 15.05
  "price_value_prices/_currency": "USD"
  "price_value_prices/_source": "$15.05" 
}]

And then access it using the [] operator.

data.results[$n]["price_value_prices/_sources"]

You cannot use / because it is another operator. If you have / or . in your field names, it is wise to use the [] operator.

Your JSON is invalid in four different ways:

1. You have a property initializer outside of any object initializer.

2. Property keys must be in double quotes in JSON.

3. You must have mas between properties in an object.

4. You have a ; at the end of it.

#2 would solve your / problem.

Here's a valid version:

{
    "results": [{
        "price_value_prices": 15.05,
        "price_value_prices/_currency": "USD",
        "price_value_prices/_source": "$15.05"
    }]
}

Assuming you parse that and assign the result to obj, you can access price_value_prices/_currency using brackets notation and quotes (any kind):

console.log(obj.results[0]["price_value_prices/_currency"]);
console.log(obj.results[0]['price_value_prices/_currency']);

Note the [0] after results, since it's an array with a single entry in it.
