如何在vis js中设置选项？

Question

如何使用 Vis.js 库在我的网络中设置选项？

我找不到任何答案。大家都说：

network.setOptions(options);

但是我不明白。我如何编辑这些选项？

我想在网络中切换zoomView。

$("#zoom-network").click(function(e) { 
    // what to do here ? 
    network.setOptions(options); 
});

编辑感谢 AlexP，我找到了答案：

$("#zoom-network").click(function(e) {
    var options = {
        interaction : {
            zoomView : true
        }
    };
    network.setOptions(options);
});

<!doctype html>
<html>
<head>
  <title>Network | Basic usage</title>

  <script type="text/javascript" src="../../dist/vis.js"></script>
  <link href="../../dist/vis.css" rel="stylesheet" type="text/css" />

  <style type="text/css">
    #mynetwork {
      width: 600px;
      height: 400px;
      border: 1px solid lightgray;
    }
  </style>
</head>
<body>

  Create a simple network with some nodes and edges.
</p>

<div id="mynetwork"></div>

<script type="text/javascript">
  // create an array with nodes
  var nodes = new vis.DataSet([
    {id: 1, label: 'Node 1'},
    {id: 2, label: 'Node 2'},
    {id: 3, label: 'Node 3'},
    {id: 4, label: 'Node 4'},
    {id: 5, label: 'Node 5'}
  ]);

  // create an array with edges
  var edges = new vis.DataSet([
    {from: 1, to: 3},
    {from: 1, to: 2},
    {from: 2, to: 4},
    {from: 2, to: 5}
  ]);

  // create a network
  var container = document.getElementById('mynetwork');
  var data = {
    nodes: nodes,
    edges: edges
  };
  var options = {};
  var network = new vis.Network(container, data);
  network.setOptions(options);
</script>
</body>
</html>

对于像缩放这样的动画你必须使用.moveTo

$("#zoom-network").click(function(e) { 
    var options = { 
      scale: 1.5,
      animation: {      
        duration: 1000,
        easingFunction: "easeInOutQuad"
      }
    }
    network.moveTo(options); 
});

Answer 3

您可以设置单独的选项（例如，如果您要提供有效日期，您可能希望只设置 "end" 选项）。因此，假设您有一个先前设置的选项对象，如上面的答案所示，如果没有设置 "end" 选项，您将使用如下代码：

 if (this.end != null) {
       this.options["end"] = this.end;
 }
