Question

There is a web application for me to build, and rather than image map, I would like to try something more elegant.

The story is, there gonna be a global map where different continents are denoted by different colors.

Say Australia is red and Asia is green.

Will there be a way that when my mouse is hovering on the shape of Australia that my code will tell me that I am hovering on Australia by checking for the color where my cursor is currently pointing at?

I know I can check for mouse coordinates on image or something else, but I really want to get something that is not depending on pre-defined values/shapes/margins.

Any idea and suggestion would be much appreciated. Thanks a lot in advance.

Answer 1

It depends on what kind of element your map is. It is definitely possible for certain elements in browsers that support canvas, but not for the whole page.
