如果没有视觉示例,很难用语言解释我在寻找什么,所以这是基本思想:
https://codepen.io/jwiggiff/full/xxwvVbr

var cube = $('.cube');
var wrapper = $('.wrapper');

$(document).mousemove((e) => {
if(!cube.hasClass('locked')) {
var deltaX = e.pageX - (wrapper.offset().left+(wrapper.width()/2));
var deltaY = e.pageY - (wrapper.offset().top+(wrapper.height()/2));
var rotateY = deltaX/($(document).width()/2) * 90;
var rotateX = deltaY/(($(document).height()/2)) * -90;
cube.css("transform", " rotateY("+rotateY+"deg) rotateX("+rotateX+"deg)");
}
});

$('.top-label').click((e) => {
cube.toggleClass('locked locked-bottom');
$('.labels div:not(.top-label)').fadeToggle();
});
$('.bottom-label').click((e) => {
cube.toggleClass('locked locked-top');
$('.labels div:not(.bottom-label)').fadeToggle();
});
$('.left-label').click((e) => {
cube.toggleClass('locked locked-right');
$('.labels div:not(.left-label)').fadeToggle();
});
$('.right-label').click((e) => {
cube.toggleClass('locked locked-left');
$('.labels div:not(.right-label)').fadeToggle();
});

在 codepen 中,如果您单击屏幕边缘的文本,它会移动当前面以覆盖整个窗口。当您单击左侧或右侧文本时,它具有预期的结果。但是,如果单击顶部或底部的文本,您会看到立方体在远离屏幕平移时有一点弧度,而左/右的则没有。任何关于导致此反弹/弧线的原因以及如何解决它的想法将不胜感激!

最佳答案

添加 rotateY(0).cube.locked.locked-bottom.cube.locked.locked-top以避免这个问题。

这有点棘手,但这是因为您正在使用 rotateY(a) rotateX(b) 应用动态转换。这不会以相同的方式过渡到 rotateX() translateZ()rotateY() translateZ() .如果您制作 rotateX() translateZ()等于 rotateY(0) rotateX() translateZ()您将有相同的过渡:

var cube = $('.cube');
var wrapper = $('.wrapper');

$(document).mousemove((e) => {
if(!cube.hasClass('locked')) {
var deltaX = e.pageX - (wrapper.offset().left+(wrapper.width()/2));
var deltaY = e.pageY - (wrapper.offset().top+(wrapper.height()/2));
var rotateY = deltaX/($(document).width()/2) * 90;
var rotateX = deltaY/(($(document).height()/2)) * -90;
cube.css("transform", " rotateY("+rotateY+"deg) rotateX("+rotateX+"deg)");
}
});

$('.top-label').click((e) => {
cube.toggleClass('locked locked-bottom');
$('.labels div:not(.top-label)').fadeToggle();
});
$('.bottom-label').click((e) => {
cube.toggleClass('locked locked-top');
$('.labels div:not(.bottom-label)').fadeToggle();
});
$('.left-label').click((e) => {
cube.toggleClass('locked locked-right');
$('.labels div:not(.left-label)').fadeToggle();
});
$('.right-label').click((e) => {
cube.toggleClass('locked locked-left');
$('.labels div:not(.right-label)').fadeToggle();
});
