I am working on a project using Canvas and KineticJS. I load/create a number of nodes and edges, and have desired functionality when I interact with these under various circumstances.
At the moment I'm binding event handlers to these objects as they're created using anonymous functions. Something like this:
Node.prototype.setupNode = function(x, y) {
this.visual.on('tap', function(e) {
console.log(this.id);
});
...
}
If I have a couple of event handlers to bind for each item, some of which are a fair number of lines of code, and I'm often binding a few hundred node and edge objects, are there more optimal ways of binding these events to these objects so that I can increase performance and decrease load time and resource usage?
Thanks in advance for any help whatsoever.
You can create a named function and then pass it's reference to the event binding function, like this:
function handleTap (e) {
//your code
}
Node.prototype.setupNode = function(x, y) {
this.visual.on('tap', handleTap);
...
}
