JSON.parse 之后的数组索引 [""0""]

Question

I'm trying to parse data like this:

{
"streets": [{
    "street": "*Gewerbegebiet1",
    "hnr_needed": true
  }, {
    "street": "Abzweig Kienbaum",
    "hnr_needed": true
  }, {
    "street": "Ahornallee (Eggersdorf)",
    "hnr_needed": true
  }, {
    "street": "Ahornallee (Rehfelde)",
    "hnr_needed": true
  }, {
    "street": "Ahornweg",
    "hnr_needed": true
  }, {
    "street": "Akazienstr. (Altlandsberg)",
    "hnr_needed": true
  }, {
    "street": "Akazienstr. (Eggersdorf)",
    "hnr_needed": true
  }, {
    "street": "Akazienweg",
    "hnr_needed": true
  }, {
    "street": "Alte Dorfstr.",
    "hnr_needed": true
  }, {
    "street": "Alte Heerstr.",
    "hnr_needed": true
  }, {
    "street": "Alte Muehle",
    "hnr_needed": true
  }, ...

with this code (data is the JSON-Array):

data = JSON.parse(data);
data = data.streets;
for (var i = 0; i <= data.length; i++) {
  street_autocomplete.push( data[i].street );
}
$('#street').prop('disabled', false);

However, the first index of the array is not [0] but [""0""]. With every other index ([1], etc) it works fine. Could you give me a pointer please?

Answer 1

Maybe you have a single index problem by iterating over the last index.

for (var i = 0; i <= data.length; i++) {
//                 ^

should be

for (var i = 0; i < data.length; i++) {
//                ^
