how to assign values to TR in google dashboard table

Question

i am using Google Dashboard's table functionality, i want to assign value of id to tr of each row that is created, i have array as follows

   var data = google.visualization.arrayToDataTable([
      ['Name', 'Donuts eaten','id'],
      ['Michael' , 5,'1'],
      ['Elisa', 7,'2'],
      ['Robert', 3,'3'],
      ['John', 2,'4'],
      ['Jessica', 6,'5'],
      ['Aaron', 1,'6'],
      ['Margareth', 8,'7']
    ]);

      var table = new google.visualization.ChartWrapper({
                    'chartType': 'Table',
                    'containerId': 'chart2',
                    dataTable: data,
                    'options': {
                        'width': '500px'
                    }
                });
                table.draw();

I am still unable to figure out if there is some way to bind values to DOM elements any help will be appreciated.

Answer 1

Here's one solution, using JQuery:

google.visualization.events.addListener(table, 'ready', function () {
  $('#chart2 .google-visualization-table-tr-odd, #chart2 .google-visualization-table-tr-even').each(function (e) {
      var idx = $('td:nth-child(2)', this).html();
      $(this).attr('id', 'row' + idx);
    });
  });

And to remove the ID column:

google.visualization.events.addListener(table, 'ready', function () {
  $('.google-visualization-table-tr-head td:nth-child(3)').remove();
  $('#chart2 .google-visualization-table-tr-odd, #chart2 .google-visualization-table-tr-even').each(function (e) {
      var td = $('td:nth-child(2)', this)
      var idx = td.html();
      td.remove();
      $(this).attr('id', 'row' + idx);
    });
  });

With sorting taken into account:

function tableCleanUp() {
  google.visualization.events.addListener(table.getChart(), 'sort', tableCleanUp2);
  tableCleanUp2();
}

function tableCleanUp2() {
  $('.google-visualization-table-tr-head td:nth-child(3)').remove();
  $('#chart2 .google-visualization-table-tr-odd, #chart2 .google-visualization-table-tr-even').each(function (e) {
      var td = $('td:nth-child(2)', this)
      var idx = td.html();
      td.remove();
      $(this).attr('id', 'row' + idx);
    });
}

google.visualization.events.addListener(table, 'ready', tableCleanUp);

Answer 2

In the simplest form it can be done as the following: tr.id = containerId;

Answer 3

There is no support in the Table visualization for assigning ID's to tr's. You have to parse the created HTML manually to set them appropriately.
