我必须将我的数据视为视觉网络格式，因此使用 cytoscape web。我使用示例链接http://lekshmideepu.blogspot.in/2012/03/cytoscape-web-examples.html来绘制具有不同颜色节点和边缘的网络，它适用于节点/边缘的颜色和大小。我需要为每个节点再设置一个事件超链接。请需要点击事件节点作为网络中的超链接？

绑定到click事件并window.location.href在处理程序中适当设置。

我创建了一个通过右键单击链接到链接的函数（显然，您可以将该部分更改为您想要的任何内容：

 cy.on('cxttap','node', function(e){
  var url=this.data('link');
   window.open(url);

});

元素的“数据”部分如下所示：

{ data: { id: 'a', name: 'a',link:'http://google.com' },classes:'a'},

假设网络数据有一个名为“link”的节点属性，你可以这样做：

vis.addListener("click", "nodes", function(evt) {
    var node = evt.target;
    var link = node.data.link;
    window.open(link);
});

看：

http://cytoscapeweb.cytoscape.org/documentation/visualization#section/addListener http://cytoscapeweb.cytoscape.org/documentation/events#section/EventType

当然，您可以从任何您想要的地方获取链接，例如存储在 JavaScript 对象中的您自己的数据缓存。您不需要将它们作为节点属性存储在 Cytoscape Web 中，但这可能更方便。
