jQuery加载json数据

Question

I have been trying to load some data from a json table using jQuery.

For some reason it's not working but I believe I had covered every aspect? I am hoping it is a syntax error that maybe has slipped through and not a total cock up from my part.

This is where I am at:

HTML:

<table id="fixtures">
  <thead>
    <tr>
      <th>Home</th>
      <th>Away</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

javascript:

var jsonDataUrl = 'http://bushell.net/football/site/includes/functions.php';

$(function() {
  $.ajax({
    type: 'GET',
    url: jsonDataUrl,
    async: false,
    jsonpCallback: 'JSON_CALLBACK',
    contentType: "application/json",
    dataType: 'json',
    success: function(data) {
      addRows($('#fixtures'), data, ['data.homeTeamName','data.awayTeamName']);
    },
    error: function(e) {
      console.log(e.message);
    }
  });
});

function addRows(table, data, fields) {
  var tbody = table.find('tbody');
  $.each(data, function(i, item) {
    tbody.append(addRow(item, fields));
  });
  return tbody;
}

function addRow(item, fields) {
  var row = $('<tr>');
  $.each(fields, function(i, field) {
    row.append($('<td>').html(item[field]));
  });
  return row;
}

Console Error:

Answer 1

You must have to set a header

header("Access-Control-Allow-Origin: *");

In your functions.php that's where you are requesting with Ajax.

See this for more information:

"No 'Access-Control-Allow-Origin' header is present on the requested resource"
