This question already has an answer here:
- d3 version 4 workaround for drag origin 1 answer
I am facing a jump issue when I drag a <rect>
.
In this question they suggest to use drag.origin() but D3 v4 version doesn't have this method anymore.
Can some body suggest how to solve the jump issue?
回答1:
Instead of origin
use subject
.
So this
.origin(function() {
var t = d3.select(this);
return {x: t.attr("x"), y: t.attr("y")};
})
will become
.subject(function() {
var t = d3.select(this);
return {x: t.attr("x"), y: t.attr("y")};
})
Working fiddle using d3 v4 is here
