Preventing Lazy Evaluation In Function Called By Fabric.js

This answer gives a helpful explication of how to add a 'link' (really, an event that redirects to a URL) to a particular object rather than to all objects on the canvas: How to ad

Solution 1:

It does appear to be about lazy evaluation/closures.

Using this beautiful answer (Javascript: Creating Functions in a For Loop), I was able to craft a solution. Posting here in the hopes it will be useful to others. See the linked answer for why it works.

var fxnArr = [];
  for( var p = 0; p < rows.length; p++ ) {
    fxnArr[fxnArr.length] = (function(val) { returnfunction(){  
        window.location.href = "mylink" + "/" + val; 
    } })(p);
  }
  for (var p = 0; p<2; p++) {
    varobject = new fabric.Circle({ radius: 10, top: 10 + 20 * p, left: 10 });
    object.on('selected', fxnArr[p] );
    canvas.add(object);
  }
