将onclick事件添加到Sigma.js中的节点

Question

I have a very simple example in sigma.js that reads a gexf-file with some additional data.

// Instanciate sigma.js and customize rendering :
var sigInst = sigma.init(document.getElementById('graph-container')).drawingProperties({
    defaultLabelColor: '#fff',
    defaultLabelSize: 14,
    defaultLabelBGColor: '#fff',
    defaultLabelHoverColor: '#000',
    labelThreshold: 6,
    defaultEdgeType: 'straight'
}).graphProperties({
    minNodeSize: 0.5,
    maxNodeSize: 5,
    minEdgeSize: 1,
    maxEdgeSize: 1
}).mouseProperties({
    maxRatio: 4
});

// Parse a GEXF encoded file to fill the graph
// (requires "sigma.parseGexf.js" to be included)
sigInst.parseGexf(gexfFile);

This is actually just taken from a tutorial. Now I'd like to add an on-click event to all nodes. Can anyone tell me a proper way to do this?

Answer 1

According to the official documentation:

s = new sigma({...});

// Bind the events:
s.bind('overNode outNode clickNode doubleClickNode rightClickNode', function(e) {
    console.log(e.type, e.data.node.label, e.data.captor);
});

(The accepted answer did not work for me.)

Answer 2

Step1 - Writing the event handler

function onClick(event) {
    window.console.log("clicked!");
} 

Step 2 - Finding the event name

I've been wondering for a while what the event name could be. It appears the "onmouseover", "onmousedown", etc have been renamed with the "onmouse" part truncated and "nodes" appended at the end.

So for a click event it will be 'downnodes'

Step 3 - Linking the handler to the click event:

You have to use the bind() function to bind an event handler to an event name.

sigInst.bind('downnodes',onClick).draw();

Thanks to Matt for providing the list.

click, rightClick, clickStage, doubleClickStage, rightClickStage, clickNode, clickNodes, doubleClickNode, doubleClickNodes, rightClickNode, rightClickNodes, overNode, overNodes, outNode, outNodes, downNode, downNodes, upNode, upNodes - all should be lowercase.
