Wht to do?

My code is

function handleResponse() {
  if (httpa.readyState == 4) {
    var response = httpa.responseText;
    if (response != 'empty') {
      alert(response);
      var foo = eval('(' + strJSON + ')');
      alert(foo);
    }
  }
}

// response alerts

[{
  "id": "1",
  "name": "Pepsodent 100g",
  "selling_price": "28.75"
}, {
  "id": "2",
  "name": "Pepsodent 40g",
