Question

我试图让Google Sankey图表为每个节点打开PDF;我打开了一个窗口，但它不会渲染PDF。它将拉出正常的网页，而不是渲染PDF。

在实践中，我会计算网址，但我现在只是使用测试页面。

我只是在小提琴中实现了这一点 - 是否存在与JSFiddle相关的某种阻塞可能是问题？

google.charts.load('current', {
  callback: function () {
    drawChart();
    window.addEventListener('resize', drawChart, false);
  },
  packages:['sankey']
});

function drawChart() {
  var data = new google.visualization.DataTable();
  data.addColumn('string', 'From');
  data.addColumn('string', 'To');
  data.addColumn('number', 'Weight');
  data.addRows([
    [ 'Geometry', 'Algebra 2', 7 ],
    [ 'Geometry','FST',3],
    [ 'FST','Precalculus',4],
    [ 'FST','Concepts of Adv Math',6],
    [ 'Honors Algebra 2', 'Honors Precalculus', 7 ],
    [ 'Honors Algebra 2', 'Precalculus', 3 ],
    [ 'Algebra', 'Geometry', 7 ],
    [ 'Precalculus','Calculus',8],
    [ 'Precalculus','AP Calculus AB',2],
    [ 'Precalculus','Concepts of Adv Math',2],
    [ 'Honors Precalculus','AP Calculus AB',8],
    [ 'Honors Precalculus','Calculus',2],
    [ 'AP Calculus AB','AP Calculus BC',8],
    [ 'AP Calculus BC','AP Statistics',3],
    [ 'Calculus', 'AP Statistics', 2]


  ]);

  // Sets chart options.
  var options = {
    width: 600,
        tooltip: { isHtml: true },
      sankey: {
          node: {
              interactivity: true,
              nodePadding: 60
          },


      }
  };
  var chart = new google.visualization.Sankey(document.getElementById('sankey_basic'));

  google.visualization.events.addListener(chart, 'select', function() {
    var sel = chart.getSelection();

    if (sel.length) {
        var sel = sel[0].name.replace(/ /g,'');
      //var url = 'http://www.xb.org/images/currtest/'+sel+'.pdf';
      var url = 'http://www.pdf995.com/samples/pdf.pdf';
      window.open(url);

    }
  });

  chart.draw(data, options);
}

PDF不是从JS中的open（）渲染的
