我在拉斐尔空间上有一些矩形。我设置了一个快速鼠标坐标显示来精确放置对象:
document.addEventListener("mousemove",function(event){
var x = event.clientX;
var y = event.clientY;
document.getElementById('position').innerHTML = " X = "+ x +" Y = "+ y;
});
然而,似乎矩形往往比预期的位置高出大约 10 像素。为什么会这样?(我也知道使用style而不是 css 文件是不好的做法,但我只是想直接玩弄拉斐尔而不用担心)
var p = Raphael("paper");
let r1, r2, r3, l1;
r1 = p.rect(200, 200, 40, 40)
.attr({
'fill': 'red',
'cursor': 'pointer',
'href': 'https://www.google.com/',
});
r2 = p.rect(277, 320, 50, 50)
.attr({
'fill': 'blue',
'cursor': 'pointer',
'href': 'https://www.google.com/',
});
p.path("M 200,200 L 240,240");
r3 = p.rect(377, 300, 30, 80)
.attr({
'fill': 'yellow',
'cursor': 'pointer',
'href': 'https://www.google.com/',
});
document.addEventListener("mousemove", function(event) {
var x = event.clientX;
var y = event.clientY;
document.getElementById('position').innerHTML = " X = " + x + " Y = " + y;
});

我怀疑我的鼠标坐标系只是关闭,但如果是这样,我不知道如何相对于 Raphael("paper");
