Mouse position in D3

Question

I just wanted to get the mouse position using D3 by using the following code:

var x = 0;

svg.on(\'mousemove\', function () {
   x = d3.mouse(this)[0];               


        

Answer 1

I suspect you might be trying some like:

var x = 0;

svg.on('mousemove', function () {
   x = d3.mouse(this)[0];         
});

console.log(x);

Unless you have super fast hands, this will always write "0" to the console because the whole script executes while you are reaching for the mouse. Try putting your snippet directly into the console, move the mouse around and then type "x" into the console. You should see the latest x value.

I hope this helps, but I may have misunderstood the question.
