有没有办法更改所选节点的节点大小而不更改选项中所有节点的大小？
这些是我的节点选项:
nodes: {
borderWidth: 1,
borderWidthSelected: 2,
physics: true,
color: {
border: '#000000',
background: '#ffffff',
highlight: {
border: '#000000',
background: '#B9B9BF'
}
},
shadow: {
enabled: false,
color: '#C11818',
size: 10,
x: 5,
y: 5
},
shape: 'circularImage',
mass: 2,
size: 25
}
我想放大所选节点，使其比其他节点更明显。
network.on("selectNode", function (params) {
var nodeId = params.nodes[0];
var node = nodes.get(nodeId);
nodeClick(nodeId, nodes, edges, network);
// var options= {
// nodes: {
// size: 40
// }
// };
// network.setOptions(options);
});
注释部分设置所有节点的大小，而不是选定节点的大小，并且节点对象也没有任何选项句柄。
最佳答案
您可以更改所选节点的字体大小以增加其大小:
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 }}
};
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
}
});
});
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
}
});
});#mynetwork {
width: 100%;
height: 100%;
border: 1px solid lightgray;
