我正在尝试实现像这样的鼠标悬停效果。
我已经能够为每个瓷砖生成所需的css3d矩阵,根据它们的位置。
我已经通过缓慢的鼠标移动实现了这种效果,但是如果我快速从一个瓷砖移动到另一个瓷砖,它就无法正确更新。在瓷砖之间显示间隙。什么是更新所有瓷砖/瓷砖坐标的最佳方法,以便我获得一致的效果?
以下是我的js代码:
$('.box').each(function() {
$(this).css('height', '284px');
$(this).css('width', '284px');
});
generateGrid = function(w, h) {
var t = this;
this.p = [];
var d = 30;
var c = Math.floor($('.w').outerWidth() / 284 + 1);
var r = Math.ceil($('.w').outerHeight() / 284) + 1;
var vc = c * r;
for (i = 0; i < vc; i++) {
var l = {
x: Math.floor(i % c) * 284,
y: Math.floor(i / c) * 284
};
this.p.push(l);
}
var m = m || {};
m.Grid = function() {
this.elms = [];
this.init();
}, m.Grid.prototype = {
init: function() {
this.createTiles();
},
animateTile: function() {
var e = this;
for (i = 0; i < e.elms.length; i++) {
console.log(i);
e.elms[i].update();
}
requestAnimationFrame($.proxy(this.animateTile, this));
},
createTiles: function() {
var c = this;
for (i = 0; i < $('.box').length; i++) {
c.elms.push(new m.tile($('.box:eq(' + i + ')'), i));
}
c.animateTile();
}
}, m.tile = function(e, i, pt) {
this.el = e;
this.i = i;
var p = t.p;
this.elX = Math.floor(i % 4) * 284,
this.elY = Math.floor(i / 4) * 284,
this.p1 = p[i + Math.floor(i / 4)],
this.p2 = p[i + Math.floor(i / 4) + 1],
this.p3 = p[i + Math.floor(i / 4) + 6]
this.p4 = p[i + Math.floor(i / 4) + 5];
this.init();
}, m.tile.prototype = {
init: function() {
this.initEvents();
},
initEvents: function() {
var e = this;
var pts = t.p;
var p1 = pts[e.i + Math.floor(i / 4)],
p2 = pts[e.i + Math.floor(i / 4) + 1],
p3 = pts[e.i + Math.floor(i / 4) + 6],
p4 = pts[e.i + Math.floor(i / 4) + 5];
$(e.el).hover(function() {
TweenMax.killTweensOf(p1),
TweenMax.killTweensOf(p2),
TweenMax.killTweensOf(p3),
TweenMax.killTweensOf(p4),
TweenMax.to(p1, .3, {
x: p1.x - d,
y: p1.y - d,
ease: Back.easeOut
}),
TweenMax.to(p2, .3, {
x: p2.x + d,
y: p2.y - d,
ease: Back.easeOut
}),
TweenMax.to(p3, .3, {
x: p3.x + d,
y: p3.y + d,
ease: Back.easeOut
}),
TweenMax.to(p4, .3, {
x: p4.x - d,
y: p4.y + d,
ease: Back.easeOut
}),
TweenMax.to(e.el, .3, {
zIndex: 10,
ease: Back.easeOut
});
}, function() {
TweenMax.killTweensOf(p1),
TweenMax.killTweensOf(p2),
TweenMax.killTweensOf(p3),
TweenMax.killTweensOf(p4);
TweenMax.to(p1, .7, {
x: p1.x + d,
y: p1.y + d,
ease: Back.easeOut
}),
TweenMax.to(p2, .7, {
x: p2.x - d,
y: p2.y + d,
ease: Back.easeOut
}),
TweenMax.to(p3, .7, {
x: p3.x - d,
y: p3.y - d,
ease: Back.easeOut
}),
TweenMax.to(p4, .7, {
x: p4.x + d,
y: p4.y - d,
ease: Back.easeOut
}),
TweenMax.to(e.el, .7, {
zIndex: 0,
ease: Back.easeOut
});
});
},
update: function() {
var e = this;
var pts = t.p;
var p1 = pts[e.i + Math.floor(i / 4)],
p2 = pts[e.i + Math.floor(i / 4) + 1],
p3 = pts[e.i + Math.floor(i / 4) + 6],
p4 = pts[e.i + Math.floor(i / 4) + 5];
BLEND.TransformElement(
{
el: e.el[0],
src: [{x: 0, y: 0}, {x: w, y: 0}, {x: w, y: h}, {x: 0, y: h}],
dest: [
{x: p1.x - e.elX,
y: p1.y - e.elY},
{x: p2.x - e.elX,
y: p2.y - e.elY},
{x: p3.x - e.elX,
y: p3.y - e.elY},
{x: p4.x - e.elX,
y: p4.y - e.elY},
]
});
}
};
t.grid = new m.Grid();
};
generateGrid(284, 284);
我的代码中的BLEND.TransformElement(el,src,dest)会给出CSS3D矩阵,它运行良好。我需要正确更新顶点。
这是我的HTML和CSS:
<style>
.box{
float: left;
background: #2b5349;
transform-origin: 0px 0px;
}
</style>
<div class="w" style=" margin-bottom:190px;display:inline-block;width: calc(284px * 4); margin:100px auto;">
<div class="box" style="background: red"></div>
<div class="box" style="background: #2b5349"></div>
<div class="box" style="background: green"></div>
<div class="box" style="background: blue"></div>
<div class="box" style="background: darkgoldenrod"></div>
<div class="box" style="background: fuchsia"></div>
<div class="box" style="background: lightpink"></div>
<div class="box" style="background: mediumspringgreen"></div>
<div class="box" style="background: burlywood"></div>
<div class="box" style="background: orange"></div>
<div class="box" style="background: gold"></div>
<div class="box" ></div>
</div>
我正在从头开始完成所有这些操作,而不使用任何外部插件来实现特定的效果。请提供一些解决方案。
我已经存储了所有瓷砖的顶点,并在鼠标悬停时进行更新。当我从一个瓷砖悬停到另一个瓷砖时,将顶点值从新值重置为原始值的动画就会停止。如何解决鼠标进入和离开事件中的顶点更新问题。
