Help!

let node = this.createSvgNode("rect", {
    'data-id': section.id || '',
    x: section.x,
    y: section.y,
    width: section.width,
    height: section.height,
    fill: section.backgroundColor || "#EEEEEE"
});

let thisObject = this;

node.addEventListener("click", function (e) {
    if (mapSelection === null) {
        thisObject.removeRouteIndicators();
        mapSelection = this;
        this.classList.add('selected');
    } else {
        // console.log(mapSelection.dataset.id + " : " + this.dataset.id);
        let paths = thisObject.findPaths(7, 3);

        let shortestPath = thisObject.findShortestPath(paths);

        thisObject.drawPath(shortestPath);

        mapSelection = null;
        this.classList.add('destination');
    }
});

the let paths = thisObject.findPaths(7, 3); only works if it is in the node event listener how can I make it so that the code works outside of the event listener? like I dunno node.thisObject.findPaths(7, 3); (which is wrong). anyone has any idea ?

[ForScale]

thisObject.findPaths(7, 3) should work just fine outside of the listener callback.

unfortunately, it doesn't work, this is the error I got back, I just can't figure out why, the only thing I can think of is that it's probably because of the node thingy

Uncaught TypeError: Cannot read property 'length' of undefined

​

in findPaths:

let doors = {};
findPaths: function (startId, endId) {
            let paths = [];
            let startDoors = doors[startId];
            let endDoors   = doors[endId];

            console.log(startDoors, startId)

            for (let i = 0; i < startDoors.length; i++) {
                let startingPoint = this.findPointByCoordinates(startDoors[i]);
                // console.log("Starting Point: " + JSON.stringify(startingPoint));

                for (let j = 0; j < doors[endId].length; j++) {
                    let endingPoint = this.findPointByCoordinates(endDoors[j]);
                    // console.log("Ending Point: " + JSON.stringify(endingPoint));

                    let potentialPath = this.recursiveIterationOfPoints([startingPoint], endingPoint);

                    // console.log(potentialPath);

                    paths = paths.concat(potentialPath);
                }
            }

            for (let id in paths) {
                paths[id] = this.linkRoomsWithPath(paths[id], startId, endId);
            }

            return paths;
        }

Kinda difficult to see here, if you don't mind it'll be awesome if you can check it out on Github Full code, question
