Ajax Json Query Directly To Python Generated Html Gets Undefined

I've been struggling three weeks for now and I'm at the dead end. Sysadmins are s*tty developers :) I'm trying to build lightweight cgi-bin python scripts to collect data and conve

Solution 1:

If I'm reading your javascript correctly, the responseText property is only set after the request has completed. Normally, these things execute asynchronously, so you register a function to be called after the data has been received. e.g.

function drawTable() {
  var drawChart = function(jsonData) {
      // Create our data table out of JSON data loaded from server.
      var data = new google.visualization.DataTable(jsonData);

      // Instantiate and draw our chart, passing in some options.
      var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
      chart.draw(data, {width: 400, height: 240});
  };

  $.ajax({
      type: "GET",
      url: "http://192.168.1.123:8099/cgi-bin/test.py",
      dataType:"json",
      async: false
  }).done(drawChart);

}

More examples can be found on in the jquery ajax documentation.
