javascript - 如何在谷歌仪表板表中为 TR 赋值

Question

我正在使用 Google Dashboard 的表格功能，我想将 id 的值分配给创建的每一行的 tr，我有如下数组

   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();

我仍然无法弄清楚是否有某种方法可以将值绑定(bind)到 DOM 元素，我们将不胜感激。

Answer 1

这是一个解决方案，使用 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);
    });
  });

并删除 ID 列:

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);
    });
  });

考虑到排序:

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);
