在vis.js中选择时是否可以设置节点上的字体颜色？

Question

我想在节点被选中时更改它们的外观。我可以更改节点和边框的颜色，但我也想更改文本的颜色。我是不是遗漏了什么或者是增强请求？

改编自与设置所选节点大小有关的：

var nodes = new vis.DataSet([
  {id: 1, label: 'Node 1'},
  {id: 2, label: 'Node 2'},
  {id: 4, label: 'Node 4'},
  {id: 5, label: 'Node 5'}
]);
var edges = new vis.DataSet([
  {from: 1, to: 2},
  {from: 2, to: 4},
  {from: 2, to: 5}
]);

var container = document.getElementById('mynetwork');
var data = { 
  nodes: nodes,
  edges: edges
};
var options = {
  interaction: { hover:true },
  nodes: { font: { size: 14, color: "#000" }}
};
var network = new vis.Network(container, data, options);

network.on("selectNode", function (params) {
  var selectedNodeId = params.nodes[0];
  var node = network.body.nodes[selectedNodeId];
  node.setOptions({
    font: {
      size: 20,
      color: "#ff0000"
    }
  });
});

network.on("deselectNode", function (params) {
  var deselectedNodeId = params.previousSelection.nodes[0];
  var node = network.body.nodes[deselectedNodeId];
  node.setOptions({
    font: {
      size: options.nodes.font.size,
      color: options.nodes.font.color
    }
  });
});

#mynetwork {
  width: 100%;
  height: 100%;
  border: 1px solid lightgray;
}

Is it possible to set the font color on nodes when selected in vis.js?
