svg.js with existing svg - svg

Question

I'm trying to implement svg.js to make a map of a clickable floorplan.
But I cannot make this work properly, or this works but doesn't work like I expected:
const map = SVG.get('mysvg');
map.click(function( event ) {
this.fill({ color: '#000' });
console.log(this);
console.log(event.target);
});
When I try to click on some area on the map, instead of change fill color I get nothing.
Actually svgjs triggers 'create' as you can see in console with inspector.
Not sure what am I doing wrong here?
I would expect that the area will change fill color?

You can use the select function as described here to create a Set. You'd then use the each() method from Set to iterate over each entry and apply the click event handler. For example:
const map = SVG.get("mysvg");
var restaurants = map.select('[id*="restaurant"]:not(g)'); // Create an svg.js Set, but do not capture the group in the set
restaurants.each(function() {
this.click(function(event) {
this.fill({ color: "#000" });
});
});
If you can edit the svg that you are using as an input, I would suggest adding a class to each of the clickable elements to use that as the reference for select. Otherwise, you'll have to do something like selecting all element id 'types' (i.e. restaurant, retail etc.) separately and concatenating the Sets using Set.add() before you do the loop to add the click listener, but that could get messy.
