我只关注felix-kling上的例子。但它只是抱怨Uncaught TypeError: Cannot read property 'getComputedStyle' of null。我正在使用chrome。当我从anotherOne复制示例时,会发生同样的错误。任何想法的人?

    <script type="text/javascript" src="jsnetworkx.js"></script>

<div id="canvas"></div>
<script type="text/javascript">
    var G = jsnx.Graph();
    G.add_nodes_from([
            [1,{color:'red'}],
            [2,{color:'green'}],
            [3,{color:'white'}]
    ]);
    G.add_edges_from([[1,2],[1,3]]);

    jsnx.draw(G,{
        element: '#demo-canvas',
        node_style: {
            fill: function(d) {return d.data.color || '#AAA';}
        }
    });



</script>

你没有id为demo-canvas的元素,所以没有要绘制的元素......你的元素被称为canvas所以......:

   jsnx.draw(G,{
        element: '#canvas',
        node_style: {
            fill: function(d) {return d.data.color || '#AAA';}
        }
    });
