Question

I’m trying to retrieve some data from a JSON response, but this doesn’t seem to work:

My javascript code:

  function recommend(response){

    var recommendedList = eval('(' + response.responseText + ')');

    $H(recommendedList).each(function(item){
          alert(item.artist);
        });     
  }

What I want is to retrieve each artist values from the JSON response.

and the JSON response is of the format:

[
 {"artist":"artist1","location":{"lat":"50.952226","lng":"5.34832","ID":28}},
 {"artist":"artist2","location":{"lat":"52.362287","lng":"4.883965","ID":32}},
  ...
]

A little help would be great. Thanks!

Answer 1

Guessing from the “$H()” that you’re using prototype, I’d just get rid of that “$H()” because the array should already be iterable.

recommendedList.each(function(item) {
  alert(item.artist);
});
